8.7 ERRORS
OVER VOLTAGE
If the GP-PWM-30-UL experiences a battery over voltage (>15.5
VDC) on battery bank 1, the controller will stop operating, and
the display will begin to ash with all icons. The controller will
resume operating when the voltage drops to a normal level
<15.5 VDC.
Icons Displayed: All symbols
The controller does not display over voltage on battery 2.
LOW VOLTAGE
Low battery 1: If the SOC of battery bank 1 reaches 0%, the
battery SOC symbol will show the text “LOW” beneath it. The
controller will continue operating in this condition and will only
stop operating if the voltage of Battery 1 drops below 9.0 VDC.
Low battery 2: If there are two battery banks connected and
the SOC of battery bank 2 reaches 0%, the battery SOC symbol
will show the text “LOW” beneath it. The controller will continue
operating in this condition and will only stop operating if the
voltage of Battery 1 drops below 9.0 VDC (this is because the
GP-PWM-30-UL is powered by Battery 1).
Icons Displayed: Battery SOC Symbol, LOW, Symbol 1 or 2
