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.
