8.2 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 you must be taken to remedy the problem.
Input error
Input is in error.
Check the wiring of inputs, disconnections, and shorts, and check the
input type.
For control output functions, output the manipulated variable matched
to the setting of the “MV at PV error” parameter (level 2 mode). Alarm
output functions are activated when the upper limit is exceeded.
Memory error
Internal memory operation is in error.
First, turn the power OFF then back ON again. If the display remains
the same, the E5EK controller must be repaired. If the display is
restored to normal, then a probable cause can be external n oise affect-
ing the control system. Check for external noise.
Control output functions turn OFF (2mA max. at 4 to 20mA output,
and output equivalent to 0% in case of other outputs). Alarm output
functions turn OFF.
A/D converter error
Internal circuits are in error.
First, turn the power OFF then back ON again. If the display remains
the same, the E5EK controller must be repaired. If the display is
restored to normal, then a probable cause can be external n oise affect-
ing the control system. Check for external noise.
Control output functions turn OFF (2mA max. at 4 to 20mA output,
and output equivalent to 0% in case of other outputs). Alarm output
functions turn OFF.
