CONTROL SYSTEM - Waukesha Engine System Manager (ESM) integrates spark timing control, speed
governing, detonation protection, start-stop control, diagnostic tools, fault logging and engine safeties.
Engine Control Unit (ECU) is central brain of the control system and main customer interface. Interface with
ESM is through 25 foot (7.6 m) harness to local panel, through MODBUS RTU slave connection RS-485
multidrop hardware, and through the Electronic Service Program (ESP). Customer connections are only
required to the local panel, fuel valve, and for 24V DC power supply. Compatible with Woodward load VHP™ Series Four ® Gas
sharing module. ESM meets Canadian Standards Association Class I, Division 2, Group D, hazardous
location requirements.

ENGINATOR® BASE – Engine, generator and radiator or heat exchanger are mounted and
aligned on a welded steel, wide flange base, designed for solid mounting on an inertia
block, with standard through–base holes for lifting.
ELECTRONIC SERVICE PROGRAM (ESP) – Microsoft® Windows-based program
provided on CD-ROM for programming and interface to ESM. Includes E-Help for
troubleshooting any ESM faults. Serial harness is provided for connection of a
customer supplied laptop to the ECU RS-232 port.
ENGINE MONITORING DEVICES – Factory mounted and wired sensors for lube oil
pressure and temperature, intake manifold temperature and pressure, and jacket
water temperature, all accessible through ESM. ESM continually monitors combustion
performance through individual knock sensors to provide detonation protection. Dual
magnetic pick-ups are used for accurate engine speed monitoring. ESM provides advanced
diagnostics of engine and all ESM sensors and logs any faults into non-volatile flash memory.

Continuous Power Rating: The highest electrical power output of the Enginator available for an unlimited number of hours per year, less maintenance. It is permissible to operate the 60
Hz Enginator with up to 10% overload for two hours in each 24 hour period.
Standby Power Rating: This rating applies to those systems used as a secondary source of electrical power. This rating is the electrical power output of the Enginator (no overload) 24
hours a day, for the duration of the primary power source outage.
Rating Standard: The Waukesha Enginator power rating descriptions are in accordance to ISO 8528, DIN6271 and BS5514. It is also valid for ISO 3046/1-1995 with an engine
mechanical efficiency of 90% and Tcra (clause 10.0) is limited to ± 10° F (5° C).
