Explanation operation
Counting takes place when count input signal Counting resumes again when count value reaches 99999999 (full scale value) then returns with count input. measurement takes place when reset input. When reset resetting takes place count becomes "0". Press front reset button when want reset manually (only panel installation type).

Note) Count becomes when reset input turned while count signal being input.

Cautions
Non-voltage input type both panel mounting board mounting types Never apply voltage non-voltage input type. This will damage internal elements. Also, since there possibility erroneous operation, connect parallel inputs non-voltage input type another counter from single input signal. Since current flow very small from count input reset input terminals panel mounting type terminals board mounting type) please relays switches with high contact reliability. When inputting with open collector transistor, transistor small signals which ICBO less always input with voltage. When wiring, keep input lines count reset inputs short possible avoid running them together with high voltage power transmission lines power conduit. Also, malfunctions might occur floating capacitance these wires exceeds 32.808 parallel wires mm2). When using mode, with wiring floating capacitance 9.843 parallel wires mm2). particular, when using shielded wiring, careful capacitance between wires. board mounting type external power supply manganese dioxide lithium batteries type: 3V). Always reset after external power applied confirm that display reads "0". Make wiring from battery counter unit short absolutely possible. Also, careful polarity. Calculate battery life with following formula. battery life LC2H current consumption [mA] battery capacity until minimum operation voltage reached [mAh] Hand solder lead terminal. solder. With soldering iron 300°C 572°F perform soldering within seconds (for soldering iron). Voltage input type aware that applying more than count input terminals reset input terminals will cause damage internal elements. external resetting level (application between reset terminals rear terminals. this case, connect terminal terminal This valid polarity; therefore, counter will work reversed. When wiring, keep input lines count reset inputs short possible avoid running them together with high voltage power transmission lines power conduit. Also, malfunctions might occur floating capacitance these wires exceeds 32.808 parallel wires mm2). Free voltage input type count input terminals free voltage input reset terminals non-voltage input. aware that application voltage that exceeds voltage range level count input terminal, application voltage reset input terminal, cause damage internal elements.

Since current flow very small from reset input terminal please relays switches with high contact reliability. When inputting reset with open collector transistor, transistor small signals which ICBO less always input with voltage. reset externally, short reset input terminals rear. Input uses high impedance circuit; therefore, erroneous operation occur influence induction voltage present. plan wiring input signal that longer (wire capacitance pF/m normal temperature), recommend filter connection bleeder resistor. reset multiple panel mounting type counters once (input same count) Non-voltage input type
Notes) following guide choosing transistors used input (Tr). Leakage current small diode possible forward voltage that voltage between terminals during reset input meets standard value (0.5 forward voltage higher.)
