10.  Warm-Up Load Delay

 - How long the engine /generator will run before it closes the "AT 

LOAD" contacts. (Default ø sec.) 

11.  Nominal RPM

 - Nominal operating RPM (1800 RPM for 60 Hz, 1500 RPM for 50 Hz). 

(Default 1800) 

12.  Engine Overspeed

 - Engine overspeed setpoint. (Default 1980 RPM [110%]) 

13.  Engine Underspeed

 - Engine underspeed setpoint. (Default 1620 RPM [90%]) 

14.  Engine Cooldown

 - How long engine will run after the remote run demand is removed. 

There are some Generator faults that will also go through a normal cooldown and proceed to 
lockout. (Default ø min.) 

15.  Post-Lube Time

 - Length of time after the genset has completed a normal run that any 

post-run lubrication system is to be activated. Set will not restart until timer expires. (Default is 
0 sec.) 

16.  Flywheel Tooth Count

 - Number of Flywheel teeth. (Default 168) 

17.  Crank Termination RPM

 - Speed to stop cranking the engine. Also considered the 

minimum engine run speed. (Default 600 RPM) 

18.  Oil Pressure Warning

 - Oil pressure at which the controller activates a warning 

indication. (Default 25 PSI) 

19.  Oil Pressure Shutdown

 - Oil pressure at which the controller shuts down the system due 

to low oil pressure. (Default 20 PSI) 

20.  High oil temperature warning

 - Oil temperature at which the controller will activate a high 

oil temperature warning alarm. (Default 245°F) 

21.  High oil temperature shutdown

 - Oil temperature at which the controller shuts down the 

system due to high oil temperature. (Default 250°F) 

22.  Low Eng. Temp. Warning

 - Coolant temperature at which the controller will activate a low 

temperature warning alarm. (Default 70°F) 

23.  High Eng. Temp. Warning

 - Coolant temperature at which the controller activates a 

warning indication. (Default 215°F) 

24.  High Eng. Temp. Shutdown

 - Coolant temperature at which the controller shuts down the 

system due to high temperature. (Default 220°F) 

25.  Battery Weak

 - Voltage setpoint for average battery voltage during cranking. Battery 

voltage that falls below this setpoint usually indicates either a bad battery or bad connections. 
(Default 8 VDC) 

Phase-out
