This will damage the internal elements. Also, since there is a possibility of erroneous operation, do not connect in parallel the inputs of a non-voltage input type and another counter from a single input signal. • Since the current flow is very small from the count input and reset input terminals ( and on the panel mounting type and terminals to and to 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 μA or less and always input with no voltage. • When wiring, try to keep all the input lines to the count 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 0.003 in2). When using 2 kHz mode, use with a wiring floating capacitance of 120 pF (3 m 9.843 ft for parallel wires of 2 mm2 0.003 in2). In particular, when using shielded wiring, be careful of the capacitance between wires. PC board mounting type • For external power supply use manganese dioxide or lithium batteries (CR type: 3V). • Always reset after external power is applied and confirm that the display reads "0". • Make the wiring from the battery to the counter unit as short as absolutely possible. Also, be careful of polarity. • Calculate battery life with the following formula. t = A/I t: battery life [h] I: LC2H current consumption [mA] A: battery capacity until minimum operation voltage is reached [mAh] • Hand solder to the lead terminal. Do not dip solder. With the tip of the soldering iron at 300 °C 572 °F perform soldering within 3 seconds (for 30 to 60 W soldering iron). Voltage input type • Be aware that applying more than 30 V DC to count input terminals and , and reset input terminals and will cause damage to the internal elements. • For external resetting use H level (application of 4.5 to 30 V DC) between reset terminals and of the rear terminals. In this case, connect (+) to terminal 3 and (-) to terminal . This is the valid polarity; therefore, the counter will not work if reversed. • When wiring, try to keep all the input lines to the count 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 0.003 in2). FIBER SENSORS LASER SENSORS Free voltage input type • Use count input terminals and for free voltage input and reset terminals and for non-voltage input. • Be aware that the application of voltage that exceeds the voltage range of the H level to the count input terminal, and the application of voltage to the reset input terminal, can cause damage to the internal elements. • Since the current flow is very small from reset input terminal , please use relays and switches with high contact reliability. • When inputting a reset with an open collector of a transistor, use a transistor for small signals in which ICBO is 1 μA or less and always input with no voltage. • To reset externally, short reset input terminals and on the rear. • 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 32.808 ft 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.
