POWERGUARD CONTROLLER FUNCTIONAL STATES
The PowerGuard is a smart controller and has the following three states:
STATE 1 – Pre Set-Up:
When you first purchase your kit the controller does not have an
rpm
trip point set
within its memory.
• The red and green
led
s alternately flash
STATE 2 – Normal Operation:
When the controller has a stored RPM trip point, it will behave in the
following way:
• When the engine is running: the green
led
will flash every 5 seconds indicating the system is active and
rpm
is being monitored
• When the engine is not running: no
led
lights will flash
• When RPM drops to zero (during normal key-off engine shutdown), the valve will perform an anti-foul
cycle (closing 0.25 sec then opening) which keeps the valve free of debris and corrosion. This results in
an extended valve life.
• If the valve is tripped manually or automatically, the valve will close and the red
led
will illuminate.
When 0
rpm
is detected and 30 seconds has elapsed, the valve will automatically re-open and red
led
light will go out.
STATE 3 – System Error:
If there is a system error detected during the initial power-up of the
PowerGuard controller, the
led
s will flash an error code as per the below sequence;
1. Rapid alternating illumination of the red and green
led
lights indicates a system error
2. A one second pause is followed by a flash code where the number of flashes is the error code as per
Flash Error Codes, as shown on page 7.
3. This cycle repeats until the error is fixed and the power to the controller is cycled.
