Timers
The controller has an internal clock which is used not only to keep time, but to ensure programed events happen at the correct
times. The following sections are used to configure settings associated with timing functions.
NOTE : The controller has an on-board backup battery to keep time even when main power is not supplied to the
unit. This battery has an unpowered (no main power) lifetime of approximately five years.
4.5.1
Engine Logic
The following settings determine how the controller starts and stops the engine. It gives the user the functionality to add delays
and timers to the sequences. Most of the settings have a switched output associated with them that must be set in the
Switched Outputs settings.
NOTE : Setting a timer's value to 0 seconds will disable the timer. Example: If Delay to Start is set to 0 seconds, the
controller will not perform a Delay to Start when starting the engine.
Timers > Engine Logic:
Name Range Default Description
Delay to Start 0 ~ 90 seconds
0 s
Amount of time to delay the starting of the engine after
receiving a command to start.
DTS Manual Run
(Delay to Start on
Manual Run) Disable Delay or
Enable Delay
Enable Delay
Determines if the the Delay to Start timer is used when the
front panel RUN button is used to start the engine.

Determines the method used to control enabling the glowplug
output. See the
Preheat Mode section for more information.
Preheat Time 0 ~ 1200 seconds

0 s
Amount of time the Glowplug output is active before cranking
the engine. Used on diesel engines to warm the engine before
cranking.
Crank Time 3 ~ 30 seconds
10 s
Amount of time the Crank output is active before going to
crank rest. This timer immediately expires upon successful
cranking.
Midheat Time 0 ~ 90 seconds
0 s
Keeps Glowplug output turned on while cranking but not
during crank rest. Output will turn off upon crank failure, crank
success or midheat time expiration.
Crank Rest Time 1 ~ 90 seconds
15 s
Amount of time to delay between each attempt to start the
engine.
Crank Attempts 1 ~ 20
3
Number of attempts to start the engine before going to an
overcrank failure.
Fuel In Rest (Fuel
Crank Rest) Fuel ON or Fuel
OFF
Fuel ON
Determines if the fuel output stays on during the crank rest
time.
RPM Disconnect 100 ~ 2000 rpm
650 rpm
Speed at which controller determines the engine has started
successfully and turns off the Crank output.
Postheat Time 0 ~ 90 seconds
0 s
Amount of time the Glowplug output remains on after crank
success and the engine is running.
False Restart
(Restart on False
Start)
Enable false start (engine stall) detection. Refer to the False Restart section.
False Check (False
Restart Detect
Time)
Engine Stall Enable, Disable Disable
If enabled, after the false restart delay and if the engine speed
goes below the crank disconnect setting (1) disables oil
pressure shutdown , and (2), after two seconds the controller
will shutdown on an "engine stall" failure.
