Action
Step Action
1 Turn the FLT POT counterclockwise to reduce the voltage (about two turns).
2 Adjust the EQL POT counterclockwise two full turns.
3 Reset the ac breaker to the ON position.
4 Hold the FLT/EQL momentary switch to EQL position.
5 Watch the DVM readings and slowly adjust the FLT potentiometer clockwise
to increase the EQL voltage to -55.5 V dc.
6 Release the FLT/EQL switch.

CAUTION
Battery stabilization requirements
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.
