S.Err indicator
Internal storage device error.
First, disconnect and then reconnect the power supply. If the display does not
change, then the E5EZ-PRR must be replaced. If the display returns, , then the
system might have been affected by electrical noise. Check for electrical noise.
Control output and alarm output off.
A potentiometer input error occurred.
Valve opening outside the -10% ~ 110% range.
Ensure that there are no wiring problems with the potentiometer, broken wires, or short
circuits.
If there are no wiring errors then the power supply can be turned on, and if the display
content has not changed it will need to be replaced. If normal operation resumes then
external interference might have been the cause, and should be avoided.
Control output will output MV based on the
Alarm output normal operation.
Electro-mechanical calibration did not completely finish.
Ensure that the potentiometer and valve drive motor were calibrated after they were
wired.
Control output, alarm output set to OFF.
