How to Use the 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 that must be taken to remedy the problem.
Meaning
Action
Input is in error.
Check the wiring of inputs, disconnections, and shorts, and check the input type and the input type jumper con-
nector.
For control output functions, output the manipulated variable matched to the setting of the
“
MV at PV error
”
param-
eter (level 2 mode). Alarm output functions are activated when the upper limit is exceeded.
Operation at Error
Meaning
Action
Internal memory operation is in error
First, turn the power OFF then back ON again. If the display remains the same, the E5CK Controller must be re-
paired. If the display is restored to normal, the probable cause may be external noise affecting the control system.
Check for external noise.
Control output functions turn OFF (2 mA max. at 4 to 20 mA output, and output equivalent to 0% in case of other
outputs). Alarm output functions turn OFF.
Operation at Error
Meaning
Action
Internal circuits are in error.
First, turn the power OFF then back ON again. If the display remains the same, the E5CK Controller must be re-
paired. If the display is restored to normal, the probable cause may be external noise affecting the control system.
Check for external noise.
Control output functions turn OFF (2 mA max. at 4 to 20 mA output, and output equivalent to 0% in case of other
outputs). Alarm output functions turn OFF.
Operation at Error
This error is output only during temperature input and is displayed for two seconds when the power is turned ON.
Calibration data is in error.
Must repair.
Both control output functions and alarm output functions are active. However, note that the readout accuracy is not
assured.
Meaning
Action
Operation at Error
Meaning
Though not an error, this is displayed when the process value exceeds the display range when the control range
(setting range
±
10%) is larger than the display range (
1999 to 9999).
When less than
“
1999
”
When greater than
“
9999
”
Control continues, allowing normal operation.
