The relays will not re-energize until both actuating devices are deactivated and then simultaneously reactivated (SSI input channels closed). The Duo-Touch SG Two-Hand Control Kit system has been designed to meet: * Type IIIC requirements of ISO 13851 (EN 574) Safety of Machinery - Two-Hand Control Devices, and * Category 4 requirements of ISO 13849-1 (EN 954-1) Safety of Machinery - Safety-Related Parts of Control Systems - Part 1: General Principles of Design The Safety Module's output signal consists of four sets of redundant, forced-guided (mechanically linked) contacts (see Figures in Electrical Installation on page 10). Circuitry within the Safety Module monitors these internal contacts and prevents an output signal from occurring if a fault is detected. A feedback loop is offered for monitoring the status of the machine control elements. WARNING: Point-of-Operation Guarding When properly installed, a two-hand control device provides protection only for the hands of the machine operator. It may be necessary to install additional safeguarding, such as safety light screens, additional two-hand controls, and/or hard guards, to protect all individuals from hazardous machinery. Failure to properly guard hazardous machinery can result in a dangerous condition which could lead to serious injury or death.

AT-xM-11KM Status Indicators The DUO-TOUCH SG Two-Hand Control Safety Module may be used as an initiation device for most powered machinery when machine cycling is controlled by a machine operator. Using a two-hand control system makes the operator a "hostage" while the hazard is present, thus limiting or preventing exposure to the hazard. The two-hand control actuators must be located in a way that hazardous motion is completed or stopped before the operator can release one or both of the buttons and reach the hazard (see Separation Distance on page 9). Simultaneous use of both hands is required, meaning that both buttons must be actuated within a very short time span. The time span is specified by ANSI/RIA R15.06, ANSI/NFPA79, and ISO 13851 (EN 574) as not more than 500 ms, even under single-fault conditions. This requirement reduces the possibility of intentional defeat and unintended initiation of the machine cycle. When used in single-cycle or single-stroke mode, the machine control must provide an anti-repeat feature so that the operator must release the two-hand control actuators after each machine cycle, before a new cycle can be initiated. In addition to the anti-repeat of the machine control, the mute inputs (M1 and M2), the Safety Stop Interface (SSI), or Backdoor Timer also may be used to halt a machine cycle. X5 X1 S23 Z1 Z2 Y2 M11 M12 M21 M22 X6 Y30 Y31 Y32 Y33 X2 CAUTION: Machine Control Must Provide Anti-Repeat Control Appropriate anti-repeat control must be provided by the machine control and is required by U.S. and International standards for single-stroke or single-cycle machines. The AT-..M-11KM DUO-TOUCH SG Two-Hand Control Safety Module can be used to assist in accomplishing anti-repeat control, but a risk assessment must be accomplished to determine the suitability of such use. The actuating devices must be protected from accidental or unintended operation. This can be accomplished by their mounting position and/or through the use of protective shields such as rings, guards or shields; see Figure 6. Install activation devices so that they are protected to prevent defeat or inadvertent actuation (STB Touch Buttons shown) on page 8 and SG Mechanical Installation. NOTE: Two-hand control and two-hand trip safeguarding protect only the operator's hands. Additional safeguarding may be required. The user must refer to the relevant standards for additional requirements for the application of two-hand control and two-hand trip devices when used for safeguarding. "Muting" of the two-hand control can only occur during a non-hazardous portion of the machine cycle. When the hand controls are muted, the operator's hands may be removed from the devices, but the Safety Module's outputs remain closed. A mute cycle can be initiated after the Safety Stop Interface (SSI) is closed and the two-hand control buttons are activated. After the Mute Enable input closes, M1 and M2 can close (within the 3-second simultaneity requirement), then the Module will start a mute cycle, light the mute lamp, and latch the outputs ON. The outputs will remain ON until M1 or M2 opens, the SSI opens, the backdoor timer expires, a lockout occurs, or the Module loses power. WARNING: Muting Limitations Muting is allowed only during the non-hazardous portion of the machine cycle. A muting application must be designed so that no single component failure can prevent the stop command or allow subsequent machine cycles until the failure is corrected (per OSHA 1910.217(c) (3)(iii)(d), and ANSI B11.19). P/N 109782 Rev.B www.bannerengineering.com - tel: 763-544-3164 3 DUO-TOUCH(R) SG Two-Hand Control Modules Part-Revolution Clutched Machinery A two-hand control safety module can be used for the following functions: "inch" (jog), "single-stroke," or "continuous" (run). Two-hand control safety modules are recognized as a means of protecting the machine operator when the hand controls are safely located and protected from false operation (see Mechanical Installation on page 7 and Separation Distance on page 9) and when properly interfaced to the machine (see Electrical Installation on page 10) to control the required stopping action. Full-Revolution Clutched Machinery A two-hand control safety module used to initiate the cycle of a full-revolution clutched machine is known as a "two-hand trip device." Two-hand trip devices are recognized as a means of protecting the machine operator when the hand controls are safely located and protected from false operation (see Mechanical Installation on page 7 and Separation Distance on page 9) and when properly interfaced to the machine (see Electrical Installation on page 10) to prevent accidental cycle initiation. Theory of Operation The input circuit of the DUO-TOUCH SG Safety Module requires simultaneous actuation (within 0.5 seconds of each other) of both twohand control actuators to generate an output signal. The timing diagram illustrates that an output signal from the DUO-TOUCH SG Safety Module occurs only if switch #1 (SW1) and switch #2 (SW2) are actuated within 0.5 seconds of each other. The output signal drops within 35 milliseconds following the release of either switch. The device output does not re-energize until both hand controls are disengaged, and then simultaneously re-actuated. This logic reduces the possibility of defeating the two-hand control by tying down one or both hand controls.

Muting M1 and M2 Inputs "Muting" is the automatic suspension of the safeguarding function of a safety device during a non-hazardous portion of the machine cycle. To mute the two-hand control buttons appropriately, the muting system's design must: 1. Identify the non-hazardous portion of the machine cycle, 2. Involve the selection of the proper muting devices, and 3. Include proper mounting and installation of those devices. The M1 and M2 muting devices must have normally open contacts, or one device with a PNP output and one device with an NPN output. Both devices must fulfill certain input requirements (see Muting Device Inputs in Specifications on page 15). Several types of devices may be used, including (but not limited to): limit switches, photoelectric sensors (opposed or polarized-retroreflective), positive-driven safety switches, and inductive proximity sensors. 4 www.bannerengineering.com - tel: 763-544-3164 P/N 109782 Rev.B DUO-TOUCH(R) SG Two-Hand Control Modules CAUTION: Do Not Use a Single Muting Device A single device, such as one relay or one switch with two N.O. output contacts, may fail due to a single fault. Such a fault could result in an unintentional mute cycle and cause an unsafe situation. Muting Device Requirements The muting devices (typically sensors or switches) must, at a minimum, comply with the following requirements: * A minimum of two independent hard-wired muting devices must be used. If the sources disagree or conflict, the mute must end or must not occur. No one source can initiate or continue a muted condition. * The muting devices either must both have normally open contacts, or one device have a PNP output and one device have an NPN output. These contacts must "close" when the switch is actuated (to initiate a mute cycle), and "open" when the switch is not actuated (to end a mute cycle) and in a power off condition. * The activation of the inputs to the muting module must be from separate sources. These sources must be mounted separately in order to prevent misadjustment or a single common mode failure resulting in an unintended muting condition. For example, this condition could cause physical damage to the mounting surface, causing both muting devices to be knocked out of alignment, resulting in false "muting" signals. Only one of these sources may pass through, or be affected by, a programmable logic controller or similar device. * The devices must be installed so they can not be easily defeated or bypassed. * The devices must be mounted so their physical position and alignment cannot change. * It must not be possible for environmental conditions (such as extreme airborne contamination) to initiate a mute condition. * The muting sensors or switches must not be set to use any delay or other timing functions (unless accomplished in such a manner that does not lessen the level of safety integrity of the system and does not create a hazard by extending the mute cycle). M3 M1 M4 M2 Figure 3. If two pairs of mute sensors are required, parallel the output (hard) contacts of M1 and M3, and M2 and M4, as shown above. 24V dc 0V dc B2 + M1 PNP - M11 M12 + M2 NPN M21 M22 - Figure 4. If solid-state output mute devices are required, use only devices with a discrete output, as shown above. Two-wire sensors should not be used due to the possibility of excessive leakage current causing a false ON condition. WARNING: Avoid Hazardous Installations Two or four independent position switches (at M1-M2 or M3-M4) must be properly adjusted or positioned so that they close only after the hazard no longer exists, and open again when the cycle is complete or the hazard is again present. If improperly adjusted or positioned, injury or death could result. The user has the responsibility to satisfy all local, state, and national laws, rules, codes, and regulations relating to the use of safety equipment in any particular application. It is extremely important to be sure that all appropriate agency requirements have been met and that all installation and maintenance instructions contained in the appropriate manuals are followed. P/N 109782 Rev.B www.bannerengineering.com - tel: 763-544-3164 5 DUO-TOUCH(R) SG Two-Hand Control Modules Examples of Muting Sensors and Switches Photoelectric Sensors (Opposed Mode) Opposed-mode sensors, which initiate the muted condition when the beam path is blocked, should be configured for Dark Operate and have open (non-conducting) output contacts in a power OFF condition. Photoelectric Sensors (Polarized Retroreflective Mode) The user must ensure that false "proxing" (activation due to shiny or reflective surfaces) is not possible. Banner "LP" sensors with linear polarization can greatly reduce or eliminate this effect. Configure sensors for Light Operate (LO or N.O.) if initiating a mute when the retroreflective target or tape is detected (e.g., home position). Configure sensors for Dark Operate (DO or N.C.) when a blocked beam path initiates the muted condition (e.g., entry/exit). Both situations must have open (non-conducting) output contacts in a power OFF condition. Positive-Opening Safety Switches Two or four independent switches, each with a minimum of one closed safety contact to initiate the mute cycle are typically used. An application using a single switch with a single actuator and two closed contacts could result in an unsafe situation. Inductive Proximity Sensors Typically used to initiate a muted cycle when a metal surface is detected. Due to the possibility of excessive leakage current causing false ON conditions, two-wire sensors are not to be used. Only three- or four-wire sensors that have discrete PNP, NPN, or hard-contact outputs separate from the input power can be used. Muting Functions and Safety Stop Interface Mute Enable (ME) Input The Mute Enable input is a non-safety-rated input. When the input is closed, a mute cycle is allowed to begin; opening this input while the Module is muted will have no effect. If the application does not require the Mute Enable function, then the X1/X2 input must be jumpered. Typical uses for Mute Enable include: * To allow the machine control logic to create a "window" for muting to begin * To inhibit muting from occurring * To reduce the chance of unauthorized or unintended defeat of the safety system Mute Lamp (ML) Output and Configuration Most applications require that a lamp (or other means) be used to indicate when the safeguard is muted; the AT-..M-11KM provides for this at terminals Z3 and Z4. This indication is selectable between a monitored or a nonmonitored output signal (NPN sinking). The monitored output will prevent the initiation of a mute if an indicator failure is detected (current draw falls below 10 mA or goes above 360 mA). If the muting function is to be used in a country governed by EN regulation (requiring the CE mark), Lamp Monitoring must be selected and the lamp used must meet applicable requirements (see Figure 5). WARNING: Mute Status Must Be Readily Observed Indication that the safety device is muted should be provided and be readily observable. Failure of this indication should be detectable and prevent the next mute, or operation of the indicator should be verified at suitable intervals. Lamp monitoring must be selected if the application requires compliance with UL 61496. In addition to fulfilling the above requirement, the Mute Lamp output also can be used to prompt the operator when the hand controls may be released. This reduces the chance of premature release of the two-hand control actuators. 6 www.bannerengineering.com - tel: 763-544-3164 P/N 109782 Rev.B DUO-TOUCH(R) SG Two-Hand Control Modules Backdoor Timer Safety Stop Interface (SSI) The SSI provides for easy integration of safeguards, E-stop buttons, process control, etc. This input is always active: opening either channel will cause the AT-..M-11KM to issue a stop command. The channels operate concurrently (both must open and re-close, but not necessarily within a certain time frame). If the SSI is not to be used, terminal X3 must be jumpered to X4, and terminal X5 must be jumpered to X6. If the SSI is to be used, the connected device(s) must have electrically isolated, redundant hard contacts (voltage-free). See Figure 11 for hookup information and Specifications on page 15 for contact specifications. A variety of safety systems can be interfaced with the SSI. Each safety application has unique application requirements, and the user is responsible for ensuring proper installation, use, and compliance with all relevant standards and regulations.

The Backdoor Timer helps to hinder the intentional defeat of the muting devices and it is also useful in detecting common mode failures that could affect the mute devices. The timer begins when the second muting device makes the simultaneity requirement (actuated within 3 seconds of the first muting device being actuated), and will allow a mute to continue for the predetermined time. After the timer expires, the mute cycle will end - no matter what the signal from the mute devices indicates - and the safety outputs will open (even if the two-hand control switches are actuated). 31 K2 32 K2 K1 13 14 31 23 32 X3 X4 S2.1 S2.2 S2.3 X5 X1 13 14 31 23 32 24 X1 X6 X2 Y30 Y31 Y32 Y33 X2 Configuration DIP Switches Mute Lamp Output (ML) S1.3/S2.3 OFF = Monitored ML* ON = Non-monitored ML S1.1/S2.1 OFF OFF ON ON Backdoor Timer S1.2/S2.2 Time OFF 30 seconds ON *60 seconds OFF 300 seconds ON Infinite * Factory Default Setting Figure 5. Backdoor Timer Setup Mechanical Installation Installation of the DUO-TOUCH SG Safety Module The Module must be installed inside a NEMA 3 (IEC IP54) rated, or better, enclosure. It is not designed for exposed wiring. See Dimensions on page 19 for Safety Module Dimensions. The device mounts directly onto a standard 35 mm DIN rail. Heat Dissipation Considerations For reliable operation, the user must ensure that the operating specifications are not exceeded. The enclosure must provide adequate heat dissipation, so that the air closely surrounding the Module does not exceed the maximum operating temperature stated in the Specifications on page 15 . Methods to reduce heat build-up include venting, forced airflow (e.g., exhaust fans), adequate enclosure exterior surface area, and spacing between modules and other sources of heat.

For complementary PNP operation, model STBVP.. touch buttons must be used to ensure proper functionality. Standards require that the actuating devices be mounted to protect them from accidental or unintentional operation. Use shields, covers, rings, collars, dividers, or simTop Mount ilar protection to prevent accidental switch actuation and to discourage use of forearms or elbows. European standard ISO13851 includes a detailed discussion of approaches to protection of hand controls. The hand controls must be arranged far enough apart so that the operator cannot Figure 6. Install activation devices so that operate both hand controls by the use of one arm. Typically, this distance is not less they are protected to prevent defeat or inadthan 550 mm/21.7" in a straight line, but using guards or alternate mounting arvertent actuation (STB Touch Buttons shown) rangement can allow shorter distances, per ISO13851 (EN574). This standard also recommends that the hand controls be arranged on a horizontal (or nearly horizonTop Plate Shield tal) surface that is 1,100 mm/43.3" above the floor. Ergonomic principles should be considered to avoid unnecessary fatigue in the installation of the hand controls. See ISO13851 (EN574) Two-Hand Control, ANSI B11.TR1-Ergonomic Guidelines, and EN894-Safety of Machinery-Ergonomic Requirements-Control Actuators for further information. The figure to the right shows two examples for mounting Banner's STB Touch ButSide Mount tons. When mounted on top of the control bar (Figure 6), the protective field covers should be in place, as shown. For added protection, mount the devices sideways under and behind a protective hood, rather than on top of the bar, leaving the field Figure 7. Mount devices sideways under a covers off (Figure 7). This side mount reduces the possibility of the operator easily protective hood for added protection (STB positioning and leaving an object in the path of the beam, intentionally bypassing Touch Buttons shown) the safeguard. CAUTION: Install Hand Controls to Prevent Accidental Actuation Total protection for the two-hand control system from "defeat" is not possible. However, the user is required by OSHA regulations to arrange and protect hand controls to minimize possibility of defeat or accidental actuation. Requirements for Multiple-Operator Control Standards have specified several conditions for situations where multiple operators work together to control one machine: * Each operator must actuate his/her own pair of actuating devices, with all pairs of actuators active at one time, in order to initiate a machine cycle; the machine may not be allowed to operate until this condition is true * The actuators all must be released between cycles * The actuation and de-actuation of all workstations requiring two-hand control must be supervisable and must provide indication * The clutch/brake control system must be designed so that the clutch cannot be actuated if all the operating workstations are bypassed It is the responsibility of the user to determine if this two-hand control system can be interfaced to the machine in a manner to satisfy all existing requirements for multiple-operator control. 8 www.bannerengineering.com - tel: 763-544-3164 P/N 109782 Rev.B DUO-TOUCH(R) SG Two-Hand Control Modules Separation Distance WARNING: Location of Touch Button Controls Hand controls must be mounted a safe distance from moving machine parts, as determined by the appropriate standard. It must not be possible for the operator or other non-qualified persons to relocate them. Failure to establish and maintain the required safety distance could result in serious injury or death. Both hand controls must be located far enough away from the nearest hazard point that the operator cannot reach the hazard with a hand or other body part before the hazardous motion ceases. This is the "separation distance," and may be calculated as follows: For Part-Revolution Clutch Machinery Where the machine and its controls allow the machine to stop motion during the hazardous portion of the machine cycle, use the following formula: Ds = K x (Ts + Tr + Th) For Full-Revolution Clutch Machinery Where the machine and its controls are designed to complete a full machine cycle, once activated, use the following formula: Ds = K x (Tm + Tr + Th) For both formulas: Ds = the separation distance in inches K = 63" per second (the hand speed constant currently accepted by OSHA; see NOTE 1) Ts = the stop time (in seconds) of the machine, measured from the application of the "stop" signal to the final ceasing of all motion, including stop times of all relevant control elements, and measured at maximum machine velocity (see NOTE 2) Tr = 0.035 seconds (the response time of the Safety Module as measured from the time a stop is signalled by either hand control) Th = the response time of the slowest hand control (from the time when a hand disengages that control until the switch opens; see NOTE 3) Tm = the maximum time (in seconds) the machine takes to cease all motion after it has been tripped. For full-revolution clutch presses with only one engaging point, Tm is equal to the time necessary for one and one-half revolutions of the crankshaft. For full-revolution clutch presses with more than one engaging point, Tm is calculated as follows: Tm = (1/2 + 1/N) x Tcy where: N = number of clutch engaging points per revolution Tcy = time (in seconds) necessary to complete one revolution of the crankshaft P/N 109782 Rev.B www.bannerengineering.com - tel: 763-544-3164 9 DUO-TOUCH(R) SG Two-Hand Control Modules Example Separation Distance (Ds) Calculation The following example illustrates the use of the formula to calculate separation distance for a part-revolution clutch machine. This example uses 0.50 seconds as a typical value for Ts and 0.02 seconds for Th: K = 63" per second Ts = 0.50 seconds (measured by a stop-time measuring device) Tr = 0.035 seconds Th = 0.02 seconds Ds = K x (Ts + Tr + Th) = 63" (0.50 + 0.035 + 0.02) = 35" In this example, both hand controls must be located no closer than 36" from the nearest hazard point. NOTE: 1. The OSHA-recommended hand speed constant K has been determined by various studies, and although these studies indicate speeds of 63"/sec to over 100"/sec, they are not conclusive determinations. The employer should consider all factors, including the physical ability of the operator, when determining the value of K to be used. 2. Ts is usually measured by a stop-time measuring device. If the specified machine stop time is used, add at least 20% as a safety factor to account for brake system deterioration. If the stop-time of the two redundant machine control elements is unequal, the slower of the two times must be used for calculating the separation distance. 3. Th is usually insignificant for purely mechanical switches. However, Th should be considered for separation distance calculation when using electronic or electromechanical (i.e. powered) hand controls. In this example, STB response time = 0.02 seconds. Electrical Installation Because the DUO-TOUCH SG Safety Module interfaces to many types of machine controls, it is not possible to give exact wiring instructions here. The following guidelines are general in nature. CAUTION: Disconnect Power Before Wiring Before making any wire connections, make certain all power is disconnected from the Safety Module and the machine to be controlled. Electrical installation of hand controls, the DUO-TOUCH SG Safety Module, and the interconnection to the machine control must be made by qualified personnel and must comply with NEC (National Electrical Code), ANSI/NFPA79 or IEC60204-1, and all applicable local standards. Dangerous voltages may be present along the Safety Module wiring barriers whenever power to the machine control elements is ON. Exercise extreme caution whenever machine control power is or may be present. Always disconnect power to the machine control elements before opening the enclosure housing of the Safety Module. 10 www.bannerengineering.com - tel: 763-544-3164 P/N 109782 Rev.B DUO-TOUCH(R) SG Two-Hand Control Modules STB2 STB1 STB2 STB1 Logic +- +- +- Brown Blue Whit e Yell ow Black Whit e Yell ow Black AT-GM- 11K M AT-HM- 11K M SW1 +- Brown Blue Whit e Z1 Z2 S12 S11 S13 S22 S21 S23 Figure 8.

SW1 and SW2 must both have normally open and normally closed output contacts, or two current-sourcing complementary outputs each, all capable of reliably switching up to 20 mA, at 12V dc. If hand controls have metal housings, the housings must be connected to protective earth ground. If STB Touch Buttons are used, connect the brown and blue wires to terminals Z1 and Z2. If electronic actuation devices other than STB Touch Buttons are used, they must share the same voltage supply with the Safety Module. WARNING: Use of Electronic Hand Controls Electronic (powered) hand controls include optical touch buttons, capacitive touch buttons and similar devices. When electronic hand controls are used as input switches for a Safety Module, the hand controls and the Safety Module must be powered from the same voltage source. Failure to do so creates a potentially dangerous condition, which could result in serious injury or death. If power is applied to the Safety Module before power is applied to the electronic hand controls, an output from the Safety Module could result and may trigger machine motion. Also, electronic hand controls cannot guarantee the state of their outputs at the time power is applied to them. Connection of Power to the DUO-TOUCH SG Safety Module The Safety Module requires a 24V dc, 115V ac or 230V ac supply voltage (see Specifications on page 15 ). Use extreme caution whenever installing ac power. Use a minimum of 16 to 18 AWG wire for power and output connections. A hand-operated supply disconnect (e.g. a circuit breaker) must be provided (per NFPA79 and IEC/EN60204). Connection to the Machine to be Controlled WARNING: Interfacing Safety Outputs NEVER wire or interface an intermediate device (e.g., PLC, PES, PC) that can fail in such a manner that there is a loss of the safety stop command to the MPCEs. To do so could result in serious bodily injury or death. Figure 11 shows a generic connection of the Safety Module's two redundant output contacts to machine primary control elements MPCE1 and MPCE2. An MPCE is defined as an electrically-powered element, external to the safety module, which directly controls the machine's normal operating motion so that it is the last (in time) to operate when motion is either initiated or arrested. Some older machines offer only one MPCE; for such machines, it may be necessary to add a second MPCE to establish the appropriate level of safety integrity (e.g., control reliability). P/N 109782 Rev.B www.bannerengineering.com - tel: 763-544-3164 11 DUO-TOUCH(R) SG Two-Hand Control Modules The connection of the safety outputs must be in such a manner that the stop command issued by the ATxM-11KM can not be overridden by a device or circuit that is not at the same level of safety integrity. This means that the safety outputs are interfaced on the output of the machine logic (e.g., PLC or PC). Then, normally, a feedback signal identifies to the machine logic the status of the safety module and, if possible, the status of the MPCEs. If interposing relays are used, they must be of mechanically linked (forced-guided) design and monitored by the MPCE Monitoring Circuit (Y1/Y2). As a summary, Control Reliability (OSHA 29CFR1910.217, ANSI B11, and ANSI/RIA R15.06) and Category 3 and 4 (ISO13849-1) requirements demand that a single failure does not lead to the loss of the safety function, or does not prevent a normal or immediate stop from occurring. The failure or the fault must be detected at or before the next demand of safety (e.g., at the beginning or end of a cycle, or when a safeguard is actuated). The safety-related function of the machine control then must issue an immediate stop command or prevent the next machine cycle or hazardous situation until the failure or fault is corrected. The user must refer to the relevant standard(s) for complete information. 11 5V ac 230V ac (Depending on mo del ) A2 A1 24V dc B1 AT-GM-11KM AT-HM-11KM B2 0V dc for AC hookup Z1 Z2 + Z3 S12 Connections to actuation devices ML Mu te Lamp S11 S13 Z4 S22 X1 S21 S23 ME Mu te Enable X2 M1 NOTE: See Figures for alternate M1/M2 hookups M2 M1 1 M1 2 Y1 M2 1 M2 2 Y2 K1 Ma chine Control Circuit MPCE1 MPCE2 (1) (1) See warn ing at ri ght reg ardi ng in termed iate swit chi ng devices K2 13 14 23 24 31 32 * MPCE 1 MPCE 2 * Feedback (op tional) SSI1 SSI2 (2) X3 X4 Y30 X5 X6 Y32 (2) +24V dc +0V dc Y31 Y33 (2) Jumper SSI input s if not used Figure 11. Machine control circuit connections As shown in Figure 11, a normally-closed, mechanically linked monitor contact from each of the two MPCEs must be connected in series across terminals Y1 and Y2. This allows the Safety Module to monitor the state of the MPCEs, and to prevent a successive machine cycle, if an MPCE fault is detected. Monitoring MPCE contacts is one method of maintaining control reliability. When MPCE monitor contacts are not available, a jumper wire must be installed across terminals Y1 and Y2. When a jumper wire is used (dotted line between Y1 and Y2 in Figure 11), it is the user's responsibility to provide an appropriate level of safety for the means of machine interfacing to ensure that any single MPCE component failure will not result in the loss of safety. WARNING: Use of Arc Suppressors If arc suppressors are used, they MUST be installed as shown across the coils of the Machine Primary Control Elements (MPCEs). NEVER install suppressors directly across the output contacts of the Safety Module. It is possible for suppressors to fail as a short circuit. If installed directly across the output contacts of the Safety Module, a short-circuited suppressor will create an unsafe condition which could result in serious injury or death. When switching inductive ac loads, it is good practice to protect the Safety Module outputs by installing appropriately-sized arc suppressors. However, if arc suppressors are used, they must be installed across the load being switched (e. g., across the coils of external safety relays), and never across the Safety Module's output contacts. 12 www.bannerengineering.com - tel: 763-544-3164 P/N 109782 Rev.B DUO-TOUCH(R) SG Two-Hand Control Modules Initial Checkout Procedure CAUTION: Disconnect Power Prior to Checkout Before performing the initial checkout procedure, make certain all power is disconnected from the machine to be controlled. Dangerous voltages may be present along the Safety Module wiring barriers whenever power to the machine control elements is ON. Exercise extreme caution whenever machine control power is or may be present. Always disconnect power to the machine control elements before opening the enclosure housing of the Safety Module. Temporarily disconnect the wires connected to the outputs of the DUO-TOUCH SG Safety Module at terminals 13/14, 23/24, 31/32, Y32, and Y33. WARNING: Do Not Use System Until Checkouts Are Verified If all of the described checks cannot be verified, do not attempt to use the two-hand control safety system until the defect or problem has been corrected. Attempts to use the guarded machine under such conditions could result in serious bodily injury or death. To perform the initial checkout, it is necessary to view the red Fault LED and the six green Status indicators. Proceed with caution around open wiring. If the SSI inputs are to be used, verify the checkout procedures for the external safety systems or other devices connected to the SSI inputs as described by the appropriate manuals. Do not proceed until all checkout procedures are completed successfully and all problems have been corrected. 1. Verify that the two actuating devices are properly connected to the DUO-TOUCH SG Safety Module. 2. Apply power to the Safety Module and to the actuating devices, if applicable. 3. Verify that only the Power indicator is ON. The SSI indicator may be ON if the Safety Stop Interface is jumpered (i.e., not used) or if the connected device is in a closed/GO condition. If any of the other Safety Module indicators are ON, disconnect the power to the Safety Module and check all wiring. Do not continue this checkout procedure until the cause of the problem is corrected. 4. With the SSI input closed (i.e., SSI LED is ON), activate both hand controls simultaneously (within 0.5 seconds), and hold them engaged. The Output indicators should come ON. Release both hand controls simultaneously. Output indicators should go OFF. 5. Again, activate the two hand controls simultaneously, and hold them engaged. The Output indicators should come ON. Release one hand control, while holding the other engaged. One of the Input indicators should remain ON. Re-activate the hand control which was just released. The Input indicator that was OFF should remain OFF. Release both hand controls. Input 1 and Input 2 indicators should then be OFF. 6. Activate only one hand control and hold it engaged. Input 1 (or Input 2) indicator should come ON. After more than 1/2 second, activate the second hand control. Input 1 (Input 2) indicator should remain ON, while Input 2 (Input 1) indicator remains OFF. 7. Release both hand controls, and open the SSI inputs (if used). Verify that the SSI LED turns OFF. Activate both hand controls simultaneously (within 0.5 seconds), and hold them engaged. Input 1 and Input 2 indicators should come ON, but the Output LED must remain OFF. 8. Remove power from the Safety Module and disconnect the monitor contact feedback loop at terminals Y1 and/or Y2. Re-apply power to the Safety Module. Close the SSI inputs, and activate both hand controls simultaneously. Input 1 and Input 2 indicator LEDs should remain OFF. If the DUO-TOUCH SG Safety Module passes all of these tests, reconnect power to the machine and the output wires at terminals 13/14, 23/24, 31/32, Y31, and Y32. Also reconnect the monitor contact feedback loop at terminals Y1 and Y2. Do not attempt to use the DUOTOUCH SG Two-Hand Control Safety Module until all of the tests are passed. Perform the Daily Checkout in Periodic Checkout and Maintenance on page 14 to verify muting function and proper operation.

Attempts to use the guarded machine under such conditions could result in serious bodily injury or death. Daily Checkout To be Performed at every Power-up, Shift Change, and Machine Setup Change: Daily checkout and checkouts after tooling and machine setup changes must be performed by a Designated Person, appointed and identified in writing by the employer. 1. 2. 3. 4. 5. 6. 7. 8. Verify that all point-of-operation guards are in place and operating properly. Verify that the two actuating devices must be simultaneously engaged to actuate the machine. For single-cycle machines: Verify that maintained engagement of the two actuating devices results in only one machine cycle. For part-revolution clutch machinery: Verify that release of either actuating device results in the immediate arrest of the machine motion. Verify that the Mute indicator comes ON during the non-hazardous portion of the machine cycle and that the muting function occurs only when exposure to the safeguarded hazard is not possible. Verify that release of the hand controls is possible during the mute cycle and that the machine cycle is not stopped. Verify that the machine cycle stops any time the mute cycle ends or when the SSI input opens. Verify that the distance from each actuating device to the closest hazard point is not less than the calculated safety distance (see Separation Distance on page 9). Semi-Annual Checkout To be Performed at Six-Month Intervals: This semi-annual checkout must be performed by a Qualified Person.* A copy of test results should be kept on or near the machine. 1. Perform the daily checkout procedure (see above). 2. Perform the initial checkout procedure (see Initial Checkout Procedure on page 13). 3. Calculate the separation distance (see Separation Distance on page 9), and verify that the actuating devices are far enough away from the nearest hazard point. Relocate the actuating devices, if necessary. 4. Verify that the actuating devices are positioned to require the use of both hands for operation, and are protected from false or inadvertent operation. 5. Inspect the machine controls and the connections to the DUO-TOUCH SG Safety Module to ensure that wiring is correct, as described in Electrical Installation on page 10, and that no modifications have been made which could adversely affect the System. * Qualified Person: A person who, by possession of a recognized degree or certificate of professional training, or who, by extensive knowledge, training, and experience, has successfully demonstrated the ability to solve problems relating to the installation, maintenance and use of the DUO-TOUCH SG Two-Hand Control Safety System. 14 www.bannerengineering.com - tel: 763-544-3164 P/N 109782 Rev.B DUO-TOUCH(R) SG Two-Hand Control Modules Specifications Supply Voltage and Current A1-A2: 115V ac (AT-GM-11KM) or 230V ac (ATHM-11KM), +/- 15%; 50/60Hz B1-B2: 24V dc, +/- 15%, 10% max. ripple Supply Protection Circuitry Protected against transient voltages and reverse polarity Power Consumption Approx. 4 W/7 VA Output Configuration Outputs (K1 and K2): two redundant (total of four) safety relay (forced-guided) contacts Contact ratings: Maximum voltage: 250V ac or 250V dc Maximum current: N.O.
