• The power supply of the standby
system is turned OFF.
• The tracking cable is disconnected or
connected without turning off or
resetting the standby system.
• The tracking cable is not secured by
the connector fixing screws.
• Since power-off of the standby
system increases the control system
scan time, reset the WDT value,
taking the increase of the control
system scan time into consideration.
• When the tracking cable is
disconnected during operation,
securely connect it and restart the
CPU module. If the same error is
displayed again, the tracking cable or
CPU module has a hardware fault.
(Contact your local Mitsubishi
representative, explaining a detailed
description of the problem.)
