Engine Protection Shutdown
MODELS AFFECTED:
All Waukesha Engines
The tables in this Service Bulletin list “Alarm” and
“Shutdown” setpoints by engine series for various
engine operation parameters. These values can be
used as a guide when designing engine protection or
monitoring systems.
The “alarm” values shown are suggested values; they
can be changed to suit a specific application or measurement device. By using controls that simultaneously shut off the fuel supply and ignition system
upon reaching a “shutdown” value, the potential for
engine damage is reduced.
Alarm and shutdown
values indicate deviation from designed operation and are not meant
for continuous engine service. Engine and control
systems must be designed to and operated at normal values. Disregarding this information could
result in product damage and/or personal injury.
CAUTION
WAUKESHA ENGINE
DRESSER, INC.
WAUKESHA, WI 53188-4999
Alarm and shutdown values are based on using dry
natural gas of 900 BTU/cu.ft. (35.38 MJ/m3
[25,V(0;101.325)]) Saturated Lower Heating Value
(SLHV) as fuel. Refer to the “Gaseous Fuel Specification for Waukesha Engines” standard sheet, S-7884-7
or latest version, and the “Lubricating Oil Recommendations for Waukesha Engines” standard sheet,
S-1015-29 or latest version, for typical changes to
operating temperatures for jacket water and lube oil
when running on landfill or digester gas fuels.
Refer to the most recent version of the Gas Engine
Price Book to determine which shutdown devices are
included as standard equipment with any specific
engine model.
