E5EZ-PRR

Meaning

Internal memory operation is in error.

Action

First, turn the power OFF then back ON again. If the display remains the same,

the Controller must be repaired. If the display is restored, then the probable

cause is electrical noise affecting the control system. Check for electrical noise.

Operation at Error

Control output and alarm output turn OFF.

Meaning

Valve opening has exceeded its regular range of

−10% to 110%.

Action

Check to see if there have been any wiring errors, burnouts, or short-circuits in

the potentiometer.

If there are no problems with the wiring, you can restart the power supply. If the

display remains the same, the Controller must be replaced. If the display is re-

stored, then the probable cause is interference which should be avoided.

Operation at Error

Control output will output MV based on the “MV during error” setting position.

Alarm output will operate as normal.

Meaning

Motor calibration did not completely finish.

Action

After confirming the potentiometer and the wiring of the motor driving valve, per-

form motor calibration again.

Operation at Error

Control output and alarm output set to OFF.
