SW 2: 1, 2, 3 - 0 Sensitivity switch:

When to switch to “1” : The highest sensitivity and the 0-90° can be divided up to around 50 times movement.

When switch to “0” : The lowest sensitivity and the 0-90° can be divided up to around 10 times movement.

The sensitivity decreases 7 times movement by sectors from SW 1 to SW 2, SW2 to SW 3,SW 3 to

SW 4 and so on.

SETTINGS FOR OPEN AND CLOSE ( FOR 0M 2 - OM 13 )

The settings are set in factory, though in some cases re-set may be requred when a particular rate of

signal is requested

OPEN SETTING

a) Keep pressing “SET” for 2 seconds, until LED 9 comes on, it will enter the manual mode.

b) Keep pressing “UP” and let the actuator run to fully-open position, LED 2 comes on, then apply

input signal ( 5V or 10V or 20mA)

c) Press “MODE” once. The “OPEN” setting is complete.

CLOSE SETTING

a) Keep pressing “DOWN” let the actuator run to fully-closed position, LED 1 comes on, then apply

input signal ( 1V or 2V or 4mA).

b) Press “MODE” once. The CLOSE” setting is complete.

After completing the above settings, press “SET” once.

LAMP SIGNAL ( FOR OM 2 - OM 13 )

LED1: When actuator is fully-closed, LED1 comes ON.LED2: When actuator is fully-open, LED2 comes ON.

LED3: When you open the power of the actuator, LED3 comes ON.LED4: When the wrong power supply is applied to the actuator, LED4 comes ON.LED5: When the wrong signal type is applied to the actuator, LED5 comes ON.LED6: When the motor thermostat opens (over-heating), LED6 comes ON.LED7: When the output signal is short-circuited, LED7 comes ON.LED8: When the motor current is excessive, LED8 comes ON.LED9: When the actuator is operated manually, LED9 comes ON

If the LED is flashing after the operating check is complete, refer to the following.

Lamp Possibilities Solution

NO LAMP a) No power supply

b) The voltage is over 260V and caused the

board to burn out.

c) Wrong connection for the # 8, #9 of the

VR.

a) Check the power supply.

b) Check the voltage.

c) Check the wiring.

LED 5 a) Setting in 2-10V input signal but supply 4-

20mA. ( LED 5 —- ON )

b) Setting in 2-10V input signal and the sig-

nal is over 13.5V ( LED 5 —-ON )** Setting in 4-20mA but supply 2-10V signal. Theactuator will operate by 2-7V. But if the signal over7.2V the LED 5 will turn on.

Confirm the input signal.

LED 6 Motor thermostat turned off. Too high frequency for rated duty cycle.

LED 7 Output signal short circuit a) Confirm the wiring of output signal # 11(-)-#12 (+).

b) Whether # 11 & # 12 output signal short circuit

LED 2, LED 7 Incorrect wiring for 2-10V output signal. Confirm the wiring of output signal # 6 (-) - # 7 (+).

LED 8 Motor current is excessive. Too high frequency for rated duty cycle.

LED 9 Manual mode- Setting position for open &

close.

After completing the settings, press “SET” once.

Use hand - wheel for test or replace valve seat

Check if any foreign objects in flow stream Check for obstructions

Broken motor stem or bearing Replace with new parts

THE ACTUATOR IS OPERATINGBUT MOTOR IS HOT


Starting the actuator too frequently. ( too high frequency

for rated duty cycle)

Change system bandwidth or replace to a higher duty

cycle actuator.

Overload This situation often happens after operating for a long

time. It is suggested to replace the valve.

Under or over requested voltage. Check the supply circuit.

The gear jams the mechanical stops in fully-open or

closed position.

Reset the mechanical stops and limit switches
