Solar Short Circuit
Charging Status LED: OFF. Solar input power wires
are short-circuited. Charging automatically resumes
when the short is cleared.
Battery Reverse Polarity
No LED indication, the unit is not powered. No
damage to the controller will result. Correct the
mis-wire to resume normal operation.
Load Short Circuit
Error status LED: Flashing red. Battery status LEDs:
R/G-Y sequencing. Fully protected against load wiring
short-circuits. After two (2) automatic load reconnect
attempts (10 seconds between each attempt) the
ProStar will wait, and then automatically reconnect the
load, once the short is cleared.
High Solar Voltage
Charging Status LED: R flashing. No battery
status indications. If the solar input open-circuit
voltage (Voc) exceeds the 60 Volt maximum rating, the
array will remain disconnected until the Voc falls safely
below the maximum voltage.
Remote Temperature Sensor (RTS)
Error status LED: Flashing red. Battery status LEDs:
R/Y - G/Y sequencing. A bad RTS connection or a
severed RTS wire has disconnected the temperature
sensor during charging. Charging automatically
resumes when the problem is fixed. To resume
operation without an RTS, disconnect all power to
the ProStar and then reconnect. If the controller is
re-started with the failure still present, the controller
may not detect that the RTS is connected, and the
LEDs will not indicate a fault. A metered model, an
RM-1 meter, or MSView PC software can be used to
determine if the RTS is working properly.
Battery / Load High Voltage disconnect (HVD)
Error status LED: Flashing red. Battery status
LEDs: R-G sequencing. Recovery will occur at HVD
re-connect threshold. See Section 7 - Technical
Specifications for values.
High Heatsink Temperature
Error status LED: Flashing red. Battery status LEDs:
R-Y sequencing. The heatsink temperature has
exceeded safe limits. Charging will cease, and the
load is disconnected. The load will automatically
be reconnected, and charging will resume when the
heatsink cools to a safe temperature.
Settings (DIP) Switch Changed
Error status LED: Flashing red. Battery status LEDs:
R-Y-G sequencing. If a settings switch is changed
while there is power to the controller, the LEDs
will begin sequencing and the solar input will be
disconnected. The controller must be re-started
to clear the fault and begin operation with the new
settings.
Custom Settings Edit
Error status LED: Flashing red. Battery status LEDs:
R-Y-G sequencing. A value has been modified in
custom settings memory. The controller will stop
charging and indicate a fault condition. After all
settings have been modified, the controller must be
