Troubleshooting guide
SYMPTOM PROBABLE CAUSE ITEMS TO EXAMINE OR CORRECT
Output does not turn ON or
deliver power to load Input signal disconnected or reverse
polarity
Charge controller Load output OFF
Load over current protection tripped
Correct Input signal wiring. An “ON” input signal must be within the range of 3 – 32VDC on CBM input
terminals and be of the proper polarity.
Create conditions where charge controller load output turns ON.
Correct fault, reset over current protection.
Output does not turn OFF
and continues to deliver
power to load Signal present on CBM input
CBM input miswired so input signal is
always present
CBM output wired reverse polarity
Charge controller load output ON. Create conditions where charge controller load output turns OFF.
Correct Input signal wiring. An “OFF” input signal must be less than 1.0V on CBM input terminals.
Reverse polarity CBM output acts like a diode and passes current. Heatsink will be hotter than normal.
Heatsink hot May be Normal Operation
Installed improperly
When properly mounted in a vertical position with unrestricted airflow and operated at maximum specified
current of 70A DC, or 40A DUO-Option 100Hz PWM, heatsink may reach
≈30°C above ambient temp.
For operation at high power heatsink must be mounted vertically to promote convection cooling and airflow
must be unrestricted. Unit must not be enclosed in a confined space.
