6. Sentry Setup Menus
6.1. Engine compatibility
The factory default settings of the SENTRY make it “out of the box” ready to operate a Cummins engine programmed
with the Emergency Vehicle Calibration. Typically, for the default configuration no values will require modification,
other than changing the desired engine rpm, high-idle rpm and pump pressure preset values.
The governor is capable of controlling any engine that allows J1939 PGN0 (Torque Speed Control) messages from a
unique source address. These engines include various Detroit Diesel DDEC engines, Mercedes Benz (MBE)
engines, Volvo, and others. Programming of the source address or other parameters on the engine ECM may be
required. The Scania engine allows control by proprietary J1939 messages and is supported by the SENTRY. In
cases where an engine does not support data link control, the SENTRY can be configured to control the engine with
an analog signal coupled to the engine remote PTO throttle input. Contact Class 1 or visit our website
(www.class1.com) for a complete engine compatibility list.
