Wiring of Power Supply
It takes more than 10 seconds for all GT units to be operable after turning on the power
supply of GT.
(The time varies according to conditions and the number of connected GT units.)
As for the power supply of GT, it is recommended to use the wiring that enables multiple GT
units to be simultaneously turned on.
If the power supplies of multiple GT units cannot be simultaneously turned on after turning on
the power supply of devices such as a PLC, an error message will be displayed and it may
take some time to make communication to be established.
(The error display disappears when all the GT units become operable.)
