NOTES ON POWER-UP BEHAVIOR
Initial Power-up:
When AC is applied to the input of the unit after the unit has been in a complete
OFF state (i.e. output has been turned off and unit not powered by valid AC),
the RUI will reflect stages in the boot sequence of the MPM control system:
o
Stage 1 – Boot up
one red and one green LED will be illuminated for 4 seconds.
o
Stage 2: Normal running -- RUI will behave as documented in
the Remote User Interface section.
Default Battery Setup:
MPM factory default operation is to power up seeking an active LiFePO
4
smart
battery communication connection. If no smart battery is discovered, the MPM
will raise a warning and enter Battery Discovery Mode. While in this mode the
MPM will continue to look for a smart battery connection and charge the
battery at a reduced current and float voltage that is safe for both SLA and
LiFePO
4
batteries.
Changing Battery Types:
The MPMView software can be used to reconfigure the unit for a different
battery type. The unit must be rebooted after changing the configuration, this
can be done from MPMView if the output is turned off and there is AC present
on the input.
“Cold” Start – Input AC NOT OK, start from Battery
If there is no input AC present, the MPM output can be “cold started” from the
battery by holding the output ON/OFF button for 3-5 seconds.

If the battery VDC is too low, cold start is not possible.

If the battery health is poor or state of charge is low, the output may
turn off shortly after cold start when the battery VDC falls below the
discharge cut-off threshold.
“Jump” Start – Input AC OK, start without battery
If the MPM is connected to a valid AC source, the unit will allow output power
to be turned on by holding the output ON/OFF button for 3-5 seconds.

If the battery VDC is too low, the MPM will attempt to recover the
battery using a specific pre-charge recovery profile for battery.
