LC4H Electronic Counter Setting the operation mode and counter Setting procedure 1) Setting the operation mode (input mode and output mode) Set the input and output modes with the DIP switches on the side of the unit. DIP switches Table 1: Setting the output mode 1 2 3 4 5 6 7 8 Item DIP switch OFF ON Operation mode Refer to table 1 Minimum reset input signal width Maximum counter setting Input mode 20 ms 30 Hz DIP switch No.
LC4H Electronic Counter Operation mode 1. Input mode For the input mode, you can choose one of the following five modes • Addition • Subtraction UP DOWN • Directive DIR • Independent IND • Phase Input mode PHASE Operation IN1 or IN2 works as an input block (gate) for the other input. *Minimum input signal width: 16.7 ms; 5 kHz: 0.1 ms • Example where IN1 is the count input and IN2 is the input block (gate).
LC4H Electronic Counter 2. Output mode For the operation mode, you can choose one of the following seven modes • Maintain output/hold count HOLD-A • Maintain output/over count I HOLD-B • Maintain output/over count II HOLD-C • One shot/over count SHOT-A • One shot/recount I SHOT-B • One shot/recount II SHOT-C • One shot/hold count SHOT-D Operation mode Maintain output Hold count HOLD-A Operation Output control is maintained after count-up completion and until resetting.
LC4H Electronic Counter Precautions during usage 1. Terminal wiring 1) When wiring the terminals, refer to the terminal layout and wiring diagrams and be sure to perform the wiring properly without errors. 2) For embedded installation applications, the screw-down terminal type is recommended. When using the pin type, use the 11P cap (ATA4861). Do not solder directly to the unit’s round pins. For front panel installation applications, use the 11-pin type DIN rail terminal block (ATC18004).
LC4H Electronic Counter 3. Conditions of usage 1) Avoid locations subject to flammable or corrosive gases, excessive dust, oil, vibrations, or excessive shocks. 2) Since the cover of the 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) If power supply surges exceed the values given below, the internal circuits may become damaged.
LC4H Electronic Counter INSTALLATIONS 1. Surface mount 1) Use the pin type timer. 2) Put the terminal socket on the board directly or put it on the DIN rail (Fig. 1) 3) Insert the timer into the terminal socket and fix it with clip. (Fig. 2) 4) On DIN rail mounting, mount the timer on the DIN rail tightly. (Fig. 1) 3) a When the water-protected type is used, comfirm the conditions with which timer with rubber gasket and panel are attached tightly.
