Adjusting the C-Series
The charging rate and voltage reconnect/disconnect setting of the controller
are adjustable via two rotary potentiometer controls. The knobs are removable
to reduce the likelihood of tampering with the settings. Calibrated scales are
provided to allow setting of the control without requiring the use of a digital
voltmeter. Visual adjustment allows an accuracy of ± 0.1 volts.
Setting Voltage Parameters
In Charge Control mode, you can adjust the bulk and float charging voltage
by adjusting the potentiometers (pots) located in the bottom center of the
controllers circuit board (for more information regarding bulk and float charging
rates, see the
Three-Stage Battery Charging Process
section of this manual).
The potentiometer scale for bulk charge voltage is calibrated from 13.0 to
15.0 volts (when the voltage jumper is set for a 12 volt system) in increments
of 0.2 volts, from 26.0 to 30.0 volts (24 volt system) in increments of 0.4 volts,
or from 52.0 to 60.0 volts (48 volt system) in increments of 0.8 volts. For float
charge voltage, the potentiometer scale is calibrated from 12.5 to 14.5 volts
(12 volt system), 25.0 to 29.0 volts (24 volt system), and from 50.0 to 58.0 volts
(48 volt system) with the same increments as above.
