FUNCTIONS

•Lock Detection

When the valve stroke does not come into deadband range

for longer than 2 minutes (approx.) due to motor locking or

some other reasons, the CRP stops power supply to the

motor.

In order to reset the lock, apply 0 % and 100 % input

repeatedly or turn the power supply off and on.

•Overload Protection

In order to protect the motor from frequent control

operations at high load (load rate ≥ 50 %), the CRP is

equipped with a thermal protector in its motor.

When the thermal protector is activated, the motor must be

cooled down at least for 30 minutes before restarting.

•Electrical Storke Limits

The valve operation can be limited within specific electrical

limits without utilizing mechanical limit switches.

Both limits are relative to the operation range adjusted with

zero/span adj. The lower limit is fixed to 3.8 mA, while the

higher limit is fixed to 20.2 mA.

•Manual Operation Handle

The CRP is manual operated in 25 turns.
