H7E@-N@P Precautions (Common) Refer to Safety Precautions for All Counters. ■ New H7E (Except for PCB-mounting Counter) !WARNING !CAUTION This product has a built-in lithium battery. Do not short-circuit the + and − terminals, charge, disassemble, deform, or expose the battery to fire. The battery may explode (break), catch fire, or cause liquid leakage. Do not use any battery other than the specified one (Y92S-36).
H7E@-N@P Count Input, Timer Input or Reset Input to More than One H7E Counter at a Time AC/DC Multi-voltage Input Models • When connecting count/timer input from an SSR to the Counter that operates with AC/DC voltage input, use OMRON’s G3TA-IA/ID SSR (for DC) whose leakage current is 0.1 mA max. or connect a bleeder resistor in parallel to the input circuit of the Counter. • PNP/NPN Universal DC Voltage Input or Leakage current: 0.1 mA max.
H7E@-N@P 7. Press the Reset Key before use (not necessary for H7ER-N,-NV,NV1). (5) Tool (1) EN/IEC Standards The count or timer input, reset input, and backlight power supply terminals of the no-voltage input or PNP/NPN universal DC voltage input models (H7E@-N,-N1, H7E@-NV(-H),-NV1(-H)) are not isolated. (2) A SELV power supply conforming to Appendix H of IEC61010-1 should be used for the count or timer input, reset input and backlight power supply terminals.
H7E@-N@P Inputs PC Board (Bad Example) Do not route the wiring of the count, timer, or reset inputs in the vicinity of, or in parallel to the wiring of high-voltage or inductive load circuits (such as motors and relays). Also, keep the wiring as short as possible. PC Board (Good Example) H7E@-N@P Large-currentconsuming components Placed far away from the power supply. Large-currentconsuming components Wired in parallel with largecurrent-carrying components.
