Clearing Errors Section 8-3
• If the overcurrent is occurring momentarily, check the abnormal current
tripping type setting on page
58. The detection of short-lived abnormal
currents can be prevented by changing the setting from instantaneous
detection (detection after 10 ms) to standard detection (detection after
80 ms).
Over-temperature Output
(A30) Displayed
When error code A30 (over-temperature) and the temperature are displayed
alternately on the seven-segment display, there are two possible causes.
Check whether the S8M's internal temperature is too high or the setting of the
over-temperature output value is too low.
Run Time Alarm (A23)
Displayed
When error code A23 (run time alarm) is displayed on the seven-segment dis-
play, check whether some component in the system requires maintenance or
there is a problem with the setting of the run time value.
• If outputting run time alarms is not required, set the alarm value to 0.0 kh.
• When you want to clear the run time, execute the clear run time operation
in Setting Mode (see page 71). The run time cannot be cleared from the
Support Tool.
