SETUP PROCEDURE
The PowerHalt is a smart controller that detects diesel engine runaway and immediately stops the engine by triggering
the emergency air shut-off valve. The unit has the following states:
UNPROGRAMMED STATE:
When you fi rst purchase your kit, the controller’s red and green lights will fl ash in an
alternating order to indicate there is no emergency engine shut-off speed programmed.
PROGRAMMED STATE:
If an emergency engine shutdown speed has been programmed to the controller’s memory,
the controller unit will act in the following way:
■
Engine off:
no lights fl ashing.
■
Engine running:
green light fl ashes every 5 seconds indicating the system is working as intended.
■
Valve actuated (manually or automatically):
the emergency shut-off has occurred and the red light on the
controller turns on for 5 seconds.
SETTING THE EMERGENCY ENGINE SHUT-OFF SPEED
If the controller has no emergency engine shutoff speed programmed, setup is required for the emergency
shut-off system to function. The controller uses a setup engine speed and adds a user defi ned overspeed margin to
program the emergency engine shut-off speed.
IMPORTANT: Please consult your engine manufacturer and the relevant safety operating procedures to determine the
emergency engine shut-off speed prior to proceeding.
1.
With the engine idling, hold down the SET and TEST buttons simultaneously until both lights begin to fl ash
(approximately 5 seconds), then release the buttons.
2.
Press and release the SET button on the controller to begin monitoring engine speed – the red light will fl ash
rapidly to confi rm the engine speed is being monitored.
3.
Bring the engine to your desired setup engine speed
GRADUALLY
, then return engine to idle.
WARNING: The controller is monitoring for the peak RPM while the engine is brought up to speed
– do not exceed your target RPM or you will need to restart this procedure.
4.
Press the SET button: 1 time to add 10% to the setup engine speed for the emergency engine shut-off speed, 2
times for 20%, 3 times for 30% or 4 times for 100%.
5.
When the data is saved successfully, the red light will confi rm your input by blinking the same number of times the
SET button was pressed. If no engine speed is detected, the controller will exit the setup and erase any saved
engine speed from the memory.
6.
Check the controller to verify that programming was successful by confi rming that the green light blinks every
5 seconds while the engine is running .
7.
Document your emergency shut-off speed for future reference.
