Setting LVR and LVD (Load Control Mode)
To change the low voltage disconnect (LVD) and low voltage reconnect
(LVR) settings, use the same BULK and FLOAT potentiometers.
When the C-Series is wired for
DC Load Control
mode, the potentiometers
scale calibration is altered from what is printed on the circuit board. A sticker
is provided with the C-Series with the proper scale calibrations for the Load
Control mode. The BULK potentiometer becomes the Low Voltage Reconnect
(LVR), and the FLOAT potentiometer becomes the Low Voltage Disconnect
(LVD). Place the sticker provided over the potentiometers. The knobs may
have to be removed for sticker placement, then reinstalled. The sticker is
packed inside the C-Series (bottom of unit).
If the sticker is lost, follow these instructions for voltage calibration using the
scale printed on the C-Series circuit board.
From the scale shown on the circuit board for the LVR setting (BULK
setting when in Charge Control mode), subtract 1 volt for 12-volt systems,
2 volts (for 24-volt systems), and 4 volts (for 48-volt systems).
From the scale shown for the LVD setting (FLOAT setting in Charge
Control mode), subtract 2 volts for the 12-volt system, 4 volts for a 24-volt
system, and 8 volts for a 48-volt system.

MANUAL reconnect of the loads is allowed when voltage has not exceeded
the LVR setting. To reconnect the loads, press the reset button on the right
side of the unit. If the voltage is below the LVR level, the DC load can be
reconnected for approximately 6 minutes. Multiple reconnects are allowed, but
the on time duration will vary with battery voltage. The EQUALIZE jumper
allows the controller to be set for AUTO reconnect of the dc load when the
voltage exceeds the LVR setting.
NOTE: The LED will light red only in Load Control mode; never in Charge or
Diversion mode (unless it is reversed upon reinstallation).

from the values printed on the
