OUTPUT VOLTAGE PULSING: 

SOLUTION: 

 

This is for lithium setting only. There is no float, but the unit will pulse high Voltage and switch off. Output 
Voltage will drop until the unit pulses again. (every 5 sec. approx.) 

 

Check the battery type has been selected correctly. 

 

UNIT CUTS IN AND CUTS OUT: 
(FAULT LIGHT SOLID THEN GOES OUT AND THEN CHARGING STATUS BLINKS FAST, SLOW OR SOLID) 

SOLUTION: 

Note: if the unit starts charging and the input Voltage drops below 9V (because of the battery on the output is being 
charged or there is high load) this brings the Voltage down, the unit will disconnect. When disconnected. The input is not 
under load, the input voltage will rise and if it goes above the Start Charge Voltage in AUTO START MODE or Low Voltage 
Reconnect in IGNITION MODE, the unit will then reconnect. 

 

The 10 second delay still applies. This means that, if the battery on the output is very low, or the load is high, the unit will 
cut in, and then cut out. This is until the input can get the output battery Voltage high enough to keep the input Voltage 
above the Cut in setting. (see below for solution)  

 

This is not a fault of the unit.  

 

The unit starts in bulk mode AND input is below Cut out Voltage (as the input and output are paralleled the 
overall input Voltage will drop depending on the charge source)  

 

This is caused by either low voltage or low current input or very flat battery or high load on output.

 

 

Check input Voltage and current at terminals. 

 

Make sure cable is correct size to avoid Voltage drop for the distance of the cable. 

 

Make sure that the charge source is supplying enough current on the input terminals. 

 

Check all connections. 

 

Increase input voltage or check for voltage drop. 

 

Reduce load. 

 

Wait for battery voltage to rise. 

 

NO BATTERY VOLTAGE LEVEL ON DISPLAY REMOTE: 

SOLUTION: 

 

Display will not show the Battery Voltage level when there is a load on the battery 

 

Check connections at green terminal block. 

 

 

CHECK ALL TROUBLE SHOOTING AND NOTES.  
IF YOU THINK THE UNIT IS FAULTY, DO NOT REPLACE WITH ANOTHER UNIT.
