Explanation of operation 1. Time measuring takes place when the start input is ON. 2. When the elapsed (measured) time reaches full scale it returns to "0", and then measuring starts again from "0". 3. When reset input is ON, the display becomes "0". You cannot measure during reset input. For PC board mounting type the display disappears while the reset input is ON; however, the display reads "0" when the reset input turns OFF. 4.

LH2H Cautions for use 1. Non-voltage input type For both panel mounting and PC board mounting types 1) Never apply voltage to the non-voltage input type. This will damage the internal elements. 2) Since the current flow is very small from the start input and reset input terminals (1 and 3 on the panel mounting type and terminals e to t and S to F on the PC board mounting type) please use relays and switches with high contact reliability. When inputting with an open collector of a transistor, use a transistor for small signals in which ICBO is 1 A or less and always input with no voltage. 3) When wiring, try to keep all the input lines to the start and reset inputs as short as possible and avoid running them together with high voltage and power transmission lines or in a power conduit. Also, malfunctions might occur if the floating capacitance of these wires exceeds 500 pF (10 m 32.808 ft. for parallel wires of 2 mm2). In particular, when using shielded wiring, be careful of the capacitance between wires. PC board mounting type 1) For external power supply use manganese dioxide or lithium batteries (CR type: 3V). 2) Always reset after external power is applied and confirm that the display reads "0". 3) Make the wiring from the battery to the hour meter unit as short as absolutely possible. Also, be careful of polarity. 4) Calculate battery life with the following formula. t = A/I t: battery life [h] I: LH2H current consumption [mA] A: battery capacity until minimum operation voltage is reached [mAh] 5) Hand solder to the lead terminal. Do not dip solder. With the tip of the soldering iron at 300C 572F perform soldering within 3 seconds (for 30 to 60 W soldering iron). 2. Voltage input type 1) Be aware that applying more than 30 V DC to start input terminals 1 and 2, and reset input terminals 3 and 4 will cause damage to the internal elements. 2) For external resetting use H level (application of 4.5 to 30 V DC) between reset terminals 3 and 4 of the rear terminals. In this case, connect + to terminal 3 and - to terminal 4. This is the valid polarity; therefore, the hour meter will not work if reversed. 3) When wiring, try to keep all the input lines to the start and reset inputs as short as possible and avoid running them together with high voltage and power transmission lines or in a power conduit. Also, malfunctions might occur if the floating capacitance of these wires exceeds 500 pF (10 m 32.808 ft. for parallel wires of 2 mm2). 3. Free voltage input type 1) Use start input terminals 1 and 2 for free voltage input and reset terminals 3 and 4 for non-voltage input. 2) Be aware that the application of voltage that exceeds the voltage range of the H level to the start input terminal, and the application of voltage to the reset input terminal, can cause damage to the internal elements. 3) Since the current flow is very small from reset input terminal 3, please use relays and switches with high contact reliability. 4) When inputting a reset with an open collector of a transistor, use a transistor for small signals in which ICBO is 1 A or less and always input with no voltage. 5) To reset externally, short reset input terminals 3 and 4 on the rear. 6) Input uses a high impedance circuit; therefore, erroneous operation may occur if the influence of induction voltage is present. If you plan to use wiring for the input signal that is 10 m or longer (wire capacitance 120 pF/m at normal temperature), we recommend the use of a CR filter or the connection of a bleeder resistor. 4.

Acquisition of CE marking Please abide by the conditions below when using in applications that comply with EN 61010-1/IEC 61010-1 1) Ambient conditions * Overvoltage category II, pollution level 2 * Indoor use * Acceptable temperature and humidity range: -10 to +55C, 35 to 85%RH (with no condensation at 20C) * Under 2000 m elevation 2) Use the main unit in a location that matches the following conditions. * There is minimal dust and no corrosive gas. * There is no combustible or explosive gas. * There is no mechanical vibration or impacts. * There is no exposure to direct sunlight. * Located away from large-volume electromagnetic switches and power lines with large electrical currents. 3) Connect a breaker that conforms to EN60947-1 or EN60947-3 to the voltage input section. 4) Applied voltage should be protected with an overcurrent protection device (example: T 1A, 250 V AC time lag fuse) that conforms to the EN/IEC standards. (Free voltage input type) 7. Terminal connection Tighten the terminal screws with a torque of 0.8 N*cm or less. Notes) 1. Use the following as a guide for choosing transistors used for input (Tr). Leakage current < 1 A 2. Use as small a diode (D) as possible in the forward voltage so that the voltage between terminals 3 and 4 during reset input meets the standard value (0.5 V). ( At IF = 20 A, forward voltage 0.1 and higher.) R Tr 5 Green or 3 4 2 3 4 Note) Make sure that H (reset ON) level is at least 4.5 V. All Rights Reserved (c) COPYRIGHT Matsushita Electric Works, Ltd.
