TEST / TROUBLESHOOTING
Refer to the status LED indicator legend on page 5, which provides diagnostics of what stage the MDP is currently
operating.
1) Testing Battery Back-up Function:
With a load connected to MDP output remove input fuse and confirm load is powered without interruption from MDP
internal battery: The two GREEN LED’s (“CHARGING” & “INPUT CONNECTED”) should extinguish and the AMBER “Back-
up Power” LED will illuminate.
2) Start-up:
When connecting or reconnecting input power to the MDP it is normal for the “INPUT CONNECTED” LED & “BACK- UP
POWER” LED to both illimunate for 2-3 seconds.
3) Charging LED:
a)
It is normal for the CHARGING LED to extinguish when the three stage charger goes in to sleep mode. (Sleep mode
reduces MDP input current draw when the internal battery is full charged.)
b)
If fuses blow repeatedly, this usually indicates a shorted component. Contact NEWMAR for further trouble shooting
advice. Always verify that the replaced fuses are of the correct rating. Use standard ATC fuses. Do no use
slow-blow fuses.
c)
Flashing Red LED - internal charging temperature exceeds 50° C.
