o
After the Float Mode LED on the Charger Control PWB becomes
lit, allow the battery voltage to stabilize for approximately
15 minutes or until the battery voltage no longer decreases.
Rotate R22, the Float Voltage potentiometer located on the
Charger Control PWB, to adjust the battery terminal voltage
to 52.4 volts. (CCW rotation decreases the float voltage.)
NOTE: In a fully charged battery, the terminal voltage may
drop very slowly to the normal float voltage. If no change
is noted as R22 is rotated, the system is not stabilized.
Allow more time and again try adjusting R22. Changes made to
R22 should be made slowly. If R22 is rotated too rapidly,
operation may be switched back to current regulating mode and
require restabilization. Battery voltage measurements should
be made with a digital voltmeter with final float voltage
adjustments within ±0.2 volts of the recommended values.
