Note: Keep 0.1s or more for power off time. PM4S Precautions during usage 4. In order to maintain the characteristics, do not remove the timer case. 5. When installing the panel, use the ATA4811 mounting frame (Sold separately). 6. If you change the operating voltage, be sure not to allow leak current into the timer. 7. Avoid leaving the unit powered continuously. Leaving the unit powered up with output set to ON continuously for a long period of time (about 1 month or more) will wear out the electronic components. If you will be keeping it powered continuously, combine with a relay to create the circuit shown below: 1. Avoid locations subject to flammable or corrosive gases, excessive dust, oil, vibrations, or excessive shocks. 2. Since the main-unit is made of polycarbonate resin, avoid contact with or use in environments containing methyl alcohol, benzene, thinners, and other organic solvents; and ammonia, caustic sodas, and other alkaline substances. 3. Power supply superimposed surge protector Although a surge protector will withstand standard-waveform voltage with the values in the next table, anything above this will destroy the internal circuit. You should therefore use a surge absorber. 12 V DC 24 V DC 500 V 100 to 120 V AC 200 to 240 V AC 4,000 V R T R * Surge waveform [(1.2x50) s uni-polar full wave voltage] R 8. The timer setting dial should only be turned within the range indicated on the dial face. Turning it too far may break the stopper and cause damage to internal components. T Acquisition of CE marking Please abide by the conditions below when using in applications that comply with EN61812-1. 1. Overvoltage category III, pollution level 2 2. The load connected to the output contact should have basic insulation. This timer is protected with basic insulation and can be doubleinsulated to meet EN/IEC requirements by using basic insulation on the load. 3. Please use a power supply that is protected by an overcurrent protection device which complies with the EN/ IEC standard (example: 250 V 1 A fuse, etc.). 4. You must use a terminal socket or socket for the installation. Do not touch the terminals or other parts of the timer when it is powered. When installing or un-installing, make sure that no voltage is being applied to any of the terminals. 5. Do not use this timer as a safety circuit. For example when using a timer in a heater circuit, etc., provide a protection circuit on the machine side. All Rights Reserved (c) COPYRIGHT Matsushita Electric Works, Ltd.

When pins 2 to 6 (screw-tightening pins x and c) are shorted (the start input is turned on) with the power supply on, the output goes on, and after the set time has elapsed, it goes off. Also, when pins 2 to 6 are released (the start input goes off), the output goes on, and after the set time has elapsed, it goes off. If the status of pins 2 to 6 (screw-tightening pins x and c) changes during the time-limit interval (the start input goes from on to off, or from off to on), the time-limit interval is restarted from the point at which the change took place. If the power supply is turned off, or pins 2 to 7 (screw-tightening pins x to v) are shorted (the reset input is turned on), a reset is carried out.

PRECAUTIONS IN USING THE PM4H SERIES 1. Input connections (PM4H-A type) 1) Be sure not to use terminal as the common terminal of the input signal as shown in Fig. A. Otherwise, the internal circuit of the timer may be damaged. Use terminal as the common terminal as shown in Fig. B. Contact input (or non-contact input) Fig. A 6 5 10 2 Operating voltage Fig. B 6 5 10 2 Operating voltage If the circuits is connected as in Fig. C, the internal circuits must be broken. Be sure to connect the circuit as in Fig. D. Fig. C 10 6 T No good 2. Input signal conditions (PM4H-A type) 1) Connection of contact input (Pin type example Reset input 2 Fig. D Stop input Good Contact input (or non-contact input) 7 Start input No good 7 3) Terminal - (screw terminal x-c) should be connected as the start input. Connect terminals - (screw terminal x-v) for reset signal input. Connect terminals - (screw terminal x-b) for stop signal input. Be sure not to connect with other terminals and apply excessive voltage. The internal circuit will be damaged. 4) The input wiring other than the power supply circuit should avoid these conditions, high-voltage wiring and parallel wiring with power wire. Wire in short with using the shielding wire or metal wiring tube. 5) For start, reset and stop input, use gold-plated contact with high reliability. Since contact bouncing causes errors in the start, use an input contact less bounce time. 6) Keep the minimum signal input time over 0.05 s. 5 6 7 2 10 6 T Good 2 2) When one input signal is simultaneously applied to more than one timer, be sure to avoid the wiring shown in Fig. E. Otherwise, the short-circuit current will flow and cause damage. Be sure to align the polarity of the power supply as shown in Fig. F. Fig. E Use gold-plated contacts with high-reliability. The bounce time at the contacts causes errors in the timer operation time. Accordingly, use start input contact whose bounce time is short. The resistance when shorted should be less than 1k, and when open resistance should be more than 100k. For the screw terminal type, connect the terminal x to the each input signal. 2) Connection of non-contact input (Pin type example) (open-collector) Input terminal 2 10 Fig. F Contact or non-contact input Input terminal 2 10 Good Input terminal 2 32 10 Power supply Stop input Power supply Start input No good 10 Reset input Input terminal 2 5 6 7 2 Apply the open-collector connection. The characteristics of the transistor used must be VCEO=10V or more, IC=10mA or more, and ICBO=6A or less. Additionally, the input impedance must be 1k or less, and the residual voltage must be 0.6V or less. For the screw terminal type, connect the terminal x to the each input signal. 3) Connection of non-contact input (Pin type example) (voltage input) Internal circuit with photoelectric sensor, etc. (The start input is turned on.) 1mA 5 6 7 Q 2 [Example of start input] Even if the open collector is not used, input is also possible from the non-contact circuit of 6 to 30V DC. In this case, the start input is turned on when the signal is turned from H to L. The residual voltage must be 0.6V or less when Q is on. On the AC type, an insulated transformer is required as the power supply for the photoelectric sensor, etc. (power supply for the input devices). Note: Keep the minimum input signal time of each signal to 0.05s or more. 3. Checking the contacts before use (PM4H-F only) When the power ON time is less than the minimum power application time, the contacts may remain in an ON state, so the state of the contacts should be checked before use. When the contacts are in an ON state, activating them once will return them to their normal state (the OFF state after time-out). (Be aware that relay characteristics may result in the contacts being in that same ON state if exposed to excessive vibration and impact during transport.) 4. Time setting To set the time, turn the set dial to a desired time within the range. Instantaneous output will be on when the dial is set to "0". When the instantaneous output is used, the dial should be set under "0" range. (Instantaneous output area) Note) When power supply is on, the time range, setting time and operation mode cannot be changed. Turn off the power supply or a reset signal is applied to set the new operation mode. If the position is not stable, the timer might mis-operate. PRECAUTIONS IN USING THE PM4H SERIES 5. Superimposed surge of power supply (PM4H series common) For the superimposed surge of power supply, the standard waveform is taken as the standard value for surge-proof voltage. If external surge occurs exceeding the specified value, the internal circuit may break down. In this case, use a surge absorption element. Operation voltage 100 to 240V AC 100 to 120V AC 200 to 240V AC 48 to 125V DC 12V DC, 24V DC 24V AC/DC Surge voltage 4,000V 500V The positive and negative voltages are applied each five times between the power pins. The typical surge absorption elements include a varistor, a capacitor, and a diode. If a surge absorption element is used, use an oscilloscope to see whether or not the foreign surge exceeding the specified value appears. 6. Acquisition of CE marking Please abide by the conditions below when using in applications that comply with EN61812-1. 1) Overvoltage category III, pollution level 2 2) This timer employs a power supply without a transformer, so the power and input signal terminals are not insulated.
