Replace
To replace the unit, follow these rules:
•
Turn off the power before replacing the unit. This includes the power to
all master and slave units in the network.
•
Make sure that the new unit is not damaged.
•
If a poor connection is the probable cause of any malfunctioning, do
these steps:
-
Clean the connectors with a clean, soft cloth and industrial-grade
alcohol.
-
Remove any lint or threads left from the cloth.
-
Install the unit again.
•
When returning a damaged unit to the OMRON dealer, include a detailed
damage report with the unit.
•
Before reconnecting the new unit, do these steps:
-
Set the EtherCAT node address to the same address as the old unit.
-
If the table registration function was used for the old unit, create a
new registration table for the new unit. See the Trajexia
Programming Manual.
Caution
The GRT1-ECT is a unit that is part of a network. If the GRT1-ECT
is damaged, it effects the whole network. Make sure that a dam-
aged GRT1-ECT is repaired immediately.
