Is the VP communicating with the controller and
software?
Check the LEDs on the VP board or run the
Health Check
report in StorLogix.
When the VP is communicating with the controller, LEDs D4
and D5 will be blinking. See “Drawing 12: VP board diagram”
on page 36 for the location of the LEDs.
Yes
– Contact Technical
Support if the VP is still not
working.
No
– Check wiring and
proceed to step 5

Is the voltage at the VP, connector P1 pins 1 & 3 (1 &
2 for AC), greater than 18 Volts? (Use a volt meter to
measure the voltage).
Create a voltage map of the site by sketching out the locations
of every AI device on the site. Use a multimeter to take DC power
readings at each device. Note these readings on the sketch. Any
device that is receiving less than 12V is underpowered and can
cause the entire system to lock up.
Yes
– Voltage is too high,
check power supply and
retest
No
– Proceed to step 4
