1.Use a multi-meter to measure the DC input and DC output
batteries as well as the respective DC-DC input/output terminals.
Battery over-voltage is 15.5-16V:
2.Disconnect any other chargers in the circuit and let the battery
rest to lower the voltage. Disconnect any sensitive loads.
3.Double check correct DIP switches
Electronic Protection
If the DC-DC is not functioning correctly, it may be undergoing an internal electronic protection
and stop normal operation. This is not indicative of a defective unit but may require some
troubleshooting to resume normal operation.
High Voltage Shutdown 16V
High Voltage Restart 15.5V
1.Use a multi-meter to measure the DC input and DC output
batteries as well as the respective DC-DC input/output terminals.
They should be similar. Battery undervoltage is below 8-10V.
2.Disconnect any other loads in the circuit and let the battery
charge.
1.Use a multi-meter in DC Volts and probe the positive line onto
the positive battery terminal and probe the negative line to the
negative battery terminal. You should see a reading within
10V~14V and be a positive number.
2.If the DC reading is negative, your poles are reversed. Fix the
wiring to return to normal operation.
Lithium batteries in reverse polarity may cause
irreversible damage to the dc-dc.
3.Lead acid batteries below 8V may need an external charger to
reach minimum DC-DC voltages; Lithium batteries will be able to
recover due to Lithium Activation.
Low Voltage Cut-out 8V (Lead Acid)
Low Voltage Restart 10V
