Clearing Errors Section 8-3
8-3 Clearing Errors
When an error has occurred, the error code will be displayed on the seven-
segment display. Eliminate the cause of the error and clear the error.
It is possible to clear an error immediately after it occurs, but once an error
has been reset, another reset operation cannot be performed for at least 15
seconds to protect the S8M's internal circuits.
Errors can be cleared (reset) by pressing the Reset Key ( ) on the S8M or
executing a Support Tool operation.
Clearing Errors with
the Reset Key
The Reset Key ( ) can be pressed for 3 s or longer to clear an error and sup-
ply power to an output that was cut off.
The following example shows the display when branch output 1 was cut off
because an abnormal current was detected. If an error occurs, first determine
the cause of the error and eliminate the cause.
Clearing the Error Press the Reset Key for at least 3 s to clear the error. Power will be supplied at
the output again.
Even if an error such as an overcurrent occurs in Setting Mode or Test Mode,
the error code will not be displayed, and the error cannot be reset with the
Reset Key.
When the S8M is switched to Run Mode, the error code will be displayed and
the error can be reset with the Reset Key.
Note When the Reset Key is pressed for 3 s, “RST” will be displayed on the seven-
segment display.
Identifying and Correcting the Cause of the Error
When an error code is displayed on the seven-segment display, determine
whether an error actually occurred or there is a problem with the parameter
setting.
Correcting Abnormal
Current Tripping (A11)
Errors
When error code A11 (abnormal current tripping) and the current are dis-
played alternately on the seven-segment display, there are two possible
causes. Check whether the load connected to the output is too large or the
current setting is too low.
• If there are too many loads connected, split up the loads.
• If the current setting is too low, increase the setting.
