System Error

A system error is an error which causes the K7GE-MG to be unable to perform the functions that it was
primarily meant to perform.
In a normal state in which a system error does not occur, self-diagnosis error output is turned ON, but
due to the occurrence of a system error, the self-diagnosis error output is turned OFF, and an external
notification is sent.
The display and output when a system error occurs are as follows:
Main Unit
Probe Unit
A system error occurs due to the following two causes.
•
Duplication of the channel numbers of Probe Units
•
Hardware failure
If a system error occurs, first of all, make sure that there is no duplication of
the channel numbers of Probe Units. If the same channel number is set,
correct it and turn ON the power again. If the K7GE-MG can be started
normally, you can use it in this condition.
If the channel numbers are not duplicated, a hardware failure has occurred.
Contact your OMRON representative for repairs.
