Transfer Switch Communication

(Units with ACCM II or later transfer switch only)
Using #18 AWG twisted pair conductors, no greater than
200 ft in length, connect Tx Rx and Tx Rx GND from the
generator control panel (B) to GND and T/R on the transfer
switch control board (C) via the low voltage access hole (D).

Fault Detection System

The generator may have to run for long periods of time with
no operator present. For that reason, the system is equipped
with sensors that automatically shut down the generator
in the event of potentially damaging conditions, such as
low oil pressure, high temperature, over speed, and other erature, o erature, ov
conditions. Refer to Fault Detection System in the operator's
manual for more detailed information.
