Description of Operation and Instructions
LSC100 Light Sequence Commander
The Allmand LSC100 Light Sequence Commander includes an engine auto start controller and a light circuit
controller in one package. The LSC100 features 5 LEDs on the face of the control panel indicating the follow-
ing from left to right.
1. Flashing red (alarm)
2. Red (glow plug)
3. Yellow (crank)
4. Green (fuel)
5. Red (power)
TO START THE UNIT MANUALLY
, turn the power switch to the up ON position and place the Auto/Manual
switch to MANUAL.
The controller will check the fuel level. If insufficient fuel is present, the control will not start and indicate an
alarm by flashing the red LED. Fuel must be added before the unit will start. If sufficient fuel is present, a glow
plug relay is closed for a period of time and the red LED is illuminated. Glow plug on time is specific to the
engine model and determined by the engine water temperature. Kubota installations have a maximum of 10
seconds, Isuzu installations have a maximum of 5 seconds, and the Cat 3003/Perkins 103-10 have a maxi-
mum glow plug on time of 60 seconds. The glow plug on time must be set specifically for the engine require-
ments during installation. After the glow plug cycle, the fuel and crank relays close.
Once the controller detects frequency, the crank relay opens and the fuel relay remains closed. If the engine
does not start after five crank cycles with a 10 second rest, an overcrank fault occurs and the red LED flashes.
Once the water temperature reaches 120°F, the light relays begin to close sequentially, with a three-second
delay in between. (NOTE: Light circuit breakers must be in the ON position or the lights will not come on.) If
the fuel level in the tank falls below 1/10 full, the shut down sequence will begin. The low fuel fault will be
indicated by a flashing red LED. It will remain flashing until the fuel is replenished above 20 percent.
If oil pressure falls below minimum levels while running an oil pressure fault will occur, All light circuits and
engine relays will then open and the engine will shut down. The fault will be indicated by the flashing red LED.
To clear the fault, position the Auto/Manual switch in the center OFF position. Temperature is also monitored
through the sender. If a temperature above 234° F. is detected, a high temperature fault will occur. The fault
will be indicated by the flashing red LED that will clear after the Auto/Manual switch is placed in the center OFF
position.
TO START THE UNIT AUTOMATICALLY
, turn the power switch to the up ON position and place the Auto/
Manual switch to Auto. This allows the unit to be remotely started by the standard photocell. Optional remote
devices can include a day timer or a wireless communication unit.
Placing the ON/OFF switch or the Auto/Manual switch to the OFF position starts the shutdown sequence that
lasts approximately 30 seconds.
If the light tower is equipped with the photocell and a timer, the control panel will include an additional switch
that will select the source of control, either timer or photocell.
