No particular maintenance is required for the GAT10-DN. Check the inspection items listed in Master
PLC User's Manual so that your system can always be used in optimal conditions.
■
Maintenance
●
The external line should not be bundled with or installed adjacently to a load line except tho se from
the main power circuit line, a high voltage line and the PLC. Otherwise it will easily be affected by
noise, surge or induction.
●
For a shielding wire or a shielded cable, one-point grounding on the PLC side is required. Depending
on the condition of external noise, however, it may be better to ground on the externa l side.

External Wiring
As one of the requirements for enabling the GAT10-DN to function thoroughly and to establish a
highly reliable system, external wiring that is not easily affected by noise is necessary. The following
are matters to be attended to for external wiring.

The GAT10-DN has a built-in RS-485 terminating resistor. To the Shimaden instrument as the final
station, attach the terminating resistor supplied as an accessory to it. However, please attach the
terminating resistor to only one instrument (final station). If attached to two or more i nstruments,
correct operation cannot be guaranteed.
Note: No devices except Shimaden instruments should be connected to the RS-485 line. Otherwise,
correct operation cannot be guaranteed.
Note: Make sure to use GAT10-DN as a terminal station of RS-485 communications.
