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 potentiometer’s

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.

Figure 24

DC Load Control Adjustment Sticker

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).

Subtract the proper voltages

from the values printed on the

circuit board, if the sticker is
