Action
Turn the FLT POT counterclockwise to reduce the voltage (about two turns).
CAUTION
Risk of equipment damage
When increasing or decreasing the float voltage on a
working system with batteries connected, always
proceed very slowly. Only turn the float potentiometer
1/4 turn at any one time then allow the batteries to
stabilize before adjusting the FLT potentiometer
again.The batteries require a period of time to stabilize
to the new voltage and current levels.
Adjust the EQL POT counterclockwise two full turns.
Reset the ac breaker to the ON position.
Hold the FLT/EQL momentary switch to EQL position.
Watch the DVM readings and slowly adjust the FLT potentiometer clockwise
to increase the EQL voltage to –55.5 V dc.
Release the FLT/EQL switch. The unit should operate normally.
Continue with Procedure 8-6, "Adjusting the float voltage."
