Lighting Control Mode (DIP 1 ON)
• A quick press and release will clear any faults or reminders
that are present. A second quick press will then conduct
a lighting test. If no faults or reminders are present, the
initial press will conduct a lighting test. A lighting test
is used to verify correct wiring in the load circuit and /
or verify that the lighting components are operational.
The lighting test will override LVD for 10 minutes - the
override duration is not programmable.
• If no faults or reminders are active, press and hold for 5
seconds to initiate an Equalization (EQ).
Reset PS-MPPT to Factory Settings
To restore factory settings: Disconnect PV; disconnect
battery power; press and hold down the push-button;
re-start the PS-MPPT by connecting the battery; keep the
push-button depressed for 10 secs.
A Custom Edit Settings fault will occur. See p. 62 in Section
5 for details. The unit will then need to be re-powered to
resume normal opertation.
4.6 Alarms
Solar Overload
No LED indication. The ProStar MPPT will limit battery
current to the 25 or 40 amp maximum rating. An over-sized
solar array will not operate at peak power. The solar array
should be less than the ProStar MPPT nominal max. input
power rating for optimal performance. See Section 7.0 -
Technical Specifications for more information.
High Temperature Current Limit
The ProStar MPPT will limit the solar input current if the
heatsink temperature exceeds safe limits. Solar charge
current will be tapered back (to 0 amps if needed) to reduce
the heatsink temperature. The ProStar MPPT is designed
to operate at full rated current at the maximum ambient
temperature. This alarm indicates that there is insufficient
airflow and that the heatsink temperature is approaching
unsafe limits. If the controller frequently reports this alarm
condition, corrective action must be taken to provide better
air flow or to re-locate the controller to a cooler spot.
High Input Voltage Current Limit
The ProStar MPPT will limit the solar input current as the
solar array Voc approaches the maximum input voltge
rating. The array Voc should never exceed the 120 volt
maximum input voltage - see the array voltage de-rating
graph in Appendix.
Current Limit
The array power exceeds the rating of the controller. This
alarm indicates that the ProStar MPPT is limiting battery
current to the maximum current rating.
RTS Open
The Remote Temperature Sensor is not connected to the
controller. Use of the RTS is recommended for proper
battery charging.
Heatsink Temperature Sensor Open / Shorted
The heatsink temperature sensor is damaged. Return the
controller to an authorized Morningstar dealer for service.
Battery Sense Out of Range / Disconnected (only alarm
with LED indications)
Error status LED: Flashing red. Battery status LEDs: R/Y
- G/Y sequencing. A battery sense wire is disconnected.
Inspect the battery sense connections. This alarm is set
when the voltage at the battery sense terminals differs
by more than five volts from the voltage at the battery
terminals.
Uncalibrated
The controller was not factory calibrated. Return the
controller to an authorized Morningstar dealer for service.
