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.
