SERVICE BULLETIN

Page 1 WAUKESHA ENGINEDRESSER, INC.WAUKESHA, WI 53188-4999

The tables in this Service Bulletin list Alarm andShutdown setpoints by engine series for variousengine operation parameters. These values can be

used as a guide when designing engine protection ormonitoring systems.

The alarm values shown are suggested values; theycan be changed to suit a specific application or mea-

surement device. By using controls that simulta-neously shut off the fuel supply and ignition system

upon reaching a shutdown value, the potential forengine damage is reduced.

Alarm and shutdown

values indicate devia-

tion from designed operation and are not meant

for continuous engine service. Engine and control

systems must be designed to and operated at nor-

mal values. Disregarding this information could

result in product damage and/or personal injury.

Alarm and shutdown values are based on using natural gas of 900 BTU/cu.ft. (35.38 MJ[25,V(0;101.325)]) Saturated Lower Heating Va

(SLHV) as fuel. Refer to the Gaseous Fuel Speciftion for Waukesha Enginesstandard sheet, S-788

or latest version, and the Lubricating Oil Recommdations for Waukesha Engines standard sh

S-1015-29 or latest version, for typical changesoperating temperatures for jacket water and lubewhen running on landfill or digester gas fuels.

Refer to the most recent version of the Gas Eng

Price Bookto determine which shutdown devices included as standard equipment with any speengine model.
