6.1.12 Remote Speed Adjustment
Potentiometer Kit (Non-ECM
Models)
The remote speed adjustment potentiometer kit
provides controller-mounted engine speed adjustment.
The adjustment range is approximately ±5%. Some
applications locate this potentiometer with the
switchgear. This kit requires an electronic governor on
the generator set. See Figure 6-26. See Section 6.2,
Accessory Connections, for terminal identifications.

6.1.13 Run Relay Kit
The run relay kit energizes only when the generator set
runs. Use the run relay kit to control air intake and
radiator louvers, alarms, and/or other signalling devices.
See Figure 6-27 and Figure 6-28.
6.1.14 Shunt-Trip Line Circuit Breaker
A shunt-trip line circuit breaker provides a 12- or 24-DC
volt solenoid within the line circuit breaker case that can
energize the trip mechanism. This feature allows the
circuit breaker to be tripped by a customer-selected fault
such as alternator overload, overspeed, overvoltage, or
defined common fault. Connection requires a shunt-trip
wiring kit and a dry contact kit. See Figure 6-29.
