Engine Parameters
1. Pre-Autostart Delay - When system is in automatic mode, sets how long unit waits after a
remote run signal is active before proceeding with automatic start sequence. (Default 5
seconds, set to zero to bypass.)
2. Pre-Heat Type - Determines how long the preheat output is active.
a. None - No preheat. (Default)
b. Pre-Crank - For strictly the preheat timer length.
c. Crank Through - Preheat for the preheat timer + crank time.
d. Bypass Timer - Preheat + crank + start up lockout bypass.
e. Warm-Up - Preheat + crank + start up lockout bypass + warm-
up.
3. Pre-Lube Time - Amount of time a prelube output stays on prior to allowing a start. (Default
ø sec.)
4. Pre-Heat Timer - Amount of time that an engine is preheated prior to cranking. (Default ø
sec.)
5. Purge Crank Time - In gaseous-fueled engine applications, a purge crank is used to
prevent gas build up and vent any accumulated gaseous fuel from the system so that it will
start with a known condition. The engine cranks for a pre-settable time with the fuel output de-
energized. (Default ø sec.)
6. Crank Time - In an automatic crank cycle the longest time that the engine cranking motor
can be energized. (Default is 15 sec.)
7. Crank Rest Time - In an automatic crank cycle, the time that the engine cranking motor is
off between crank attempts. (Default 15 sec.)
8. Start Attempts - The maximum number of times that the engine cranking motor is
energized without a successful engine start. (Default 3 cycles)
9. Startup Bypass Time - Temporarily disables the low engine oil pressure, high engine
temperature and various other shutdown faults until the engine can come to a running
condition. (Default 15 sec.)
