LC2H 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. 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.

LC2H How to set 1. Preset value setting mode This is the mode for setting preset values. 2) The display reads “Un-Lock” after entering the lock mode (initial setting). Display after entering lock mode (Example showing “Un-Lock”.) Press the MODE key. Set the digit. Set the value. 1) Pressing the MODE key takes you to the preset value setting mode. 3) Pressing the setting key changes the display between “ Lock” and “Unlock”.
LC2H 5. Output setting mode This sets the operation mode. 2) Lock mode + Press the SET key while pressing the MODE key. HOLD-A SHOT-B HOLD-B SHOT-A 1) Pressing the SET key four times while holding down the MODE key takes you to the output setting mode. 2) The display reads “HoLd-A” (initial setting) after entering the output setting mode. + Press the SET key while pressing the MODE key. Un-Lock Lock When the lock is set, you cannot enter modes other than backlight setting mode.
LC2H Operation mode Output mode Output maintain/ hold count HOLD-A Operation Output control is maintained after count-up completion and until resetting. During that time, the count display does not change from that at count-up completion.
LC2H Cautions for use 1. Input and output connection 1) Input connection (1) Contact input Use highly reliable metal plated contacts. Since the contact’s bounce time leads directly to error in the count value, use contacts with as short a bounce time as possible. In general, select input to have a maximum counting speed of 30 Hz. Count input 1 2 5 6 3 4 Reset input (2) Non-contact input (Transistor input) Connect with an open collector.
LC2H PRECAUTIONS IN USING THE LC2H SERIES Cautions for use 1. Insulation sheet Before using a panel mounting type, please pull and remove the insulation sheet from the side of the product in the direction of the arrow. In consideration that the product might be stored for long periods without being used, an insulation sheet is inserted before shipping. Remove the insulation sheet and press the front reset button.
LC2H For LC2H total counter (installation frame type) (1) Remove the battery cover from the case. (2) Remove the battery from the side of the case. The battery will come loose if you put the battery side face down and lightly shake the unit. (3) Before inserting wipe clean the surface of the new battery. (4) Insert the new battery with the “+” and “–” sides in the proper position. (5) After replacing the battery, return the battery cover to the case.

TYPICAL COUNTER APPLICATIONS The highly accurate, reliable counters can be controlled from the front panel and are suitable for a wide range of applications. DOWN and HOLD-A modes for shipment quantity counting IND and HOLD-D modes for parking lots PHASE and HOLD-A modes for valve control Rotary encoder To valve FULL VACANT Photoelectric switch IN1 (up count) Motor IN2 (down count) (stop/start) Entrance Photoelectric switch Shipment quantities are counted to control the conveyor line flow.
COUNTER-RELATED TERMINOLOGY 1. Electro Preset Counter The counter is equipped with semiconductor counting circuitry. When the counter counts up to a preset number, its output circuit sends a signal. 2. Electro Magnetic Counter A magnet is magnetized and demagnetized to drive the dial and count up numbers. RATING 1. Rated Operating Voltage The voltage is applied to start the counter. COUNTINGS 1. Pulse This is a voltage or current signal sent at intermittent time intervals. 2.
PRECAUTIONS IN USING THE COUNTER Cautions for circuits 1. Protective circuit for counter contact In the circuit that switches an inductive load, a contact failure may occur at a contact point due to surge or inrush current resulting from that switching. Therefore, it is recommended that the following protective circuit be used to protect the contact point. Application AC DC (see note.) Available r c Diode Available Available If the load is a relay or solenoid, the release time lengthens.
PRECAUTIONS IN USING THE COUNTER Cautions for use (common for all models) 1. Terminal connections Correctly connect the pins while seeing the terminal layout/wiring diagram. In particular, the DC type, which has polarities, does not operate with the polarities connected reverse. Any incorrect connection can cause abnormal heating or ignition. 2. Connection to operating voltage 1)Apply the entire supply voltage through a switch, relay or other contact.

INSTALLING DIN SIZE COUNTER Installation methods 1. Surface mount 1) For the counters of LC4H series, use the pin type counter. 2) How to mount the counter From the panel front, pass the counter through the square hole. Fit the mounting frame from the rear, and then push it in so that the clearance between the mounting frame and the panel surface is minimized. In addition, lock the mounting frame with a screw. 2) Put the terminal socket on the board directly or put it on the DIN rail (Fig. 1).
