ERROR DISPLAY
When an error has occurred, the No.1 display alternately indicates error
codes together with the current display item.
This section describes how to check error codes on the display, and the
actions you must take to remedy the problem.
Input error
The input value has exceeded the control range.
* Control range
Platinum resistance
thermometer,
thermocouple input
: Temperature setting lower limit -20_C to
temperature setting upper limit +20_C
(temperature setting lower limit -40_F to
temperature setting upper limit +40_F)
ESIA input : Same as input indication range
Check the wiring of inputs for miswiring, disconnections, and shortĆcirĆ
cuits and the input type.
If no abnormality is found in the wiring and input type, turn the power
OFF then back ON again. If the display remains the same, the E5GN must
be repaired. If the display is restored, then a probable cause can be electriĆ
cal noise affecting the control system. Check for electrical noise.
After the error occurs, the error is displayed, and control output functions
turn OFF.
Alarm outputs function as if the upper limit value has been exceeded.
When output input error" (advanced function level) is set to ON, the
alarm 1 output turns ON when an input error occurs.
An error message is displayed when process value" or PV/SP" are disĆ
played.
Memory error
Internal memory operation is in error.
First, turn the power OFF then back ON again. If the display remains the
same, the E5GN must be repaired. If the display is restored, then a probĆ
able cause can be electrical noise affecting the control system. Check for
electrical noise.
Control output and alarm output turn OFF.
