Operating Procedure
Troubleshooting
When an error has occurred, the display No.1 shows the error code.
Take necessary measure according to the error code, referring the following table.
The control output and the alarm output will turn OFF when an error occurs. (For s.err, the alarm output will be processed for a high temperature
error.)
If the input value exceeds the display limit (1999 to 9999) but it is still within the control range, [[[[ will be displayed for values under 1999.
Under these conditions, the control output and alarm output will operate normally.
*1. This error is displayed only when the process value and set point are displayed.
*2. If the display does not change, the Controller needs to be repaired.
If operation returns to normal, then noise may have caused the problem. Check for noise.
*3. e111 will be displayed on display No. 1 and sum will be displayed on display No. 2.
