Specialty Concepts SC2 - Manual (Page 11)

OPTION F - VOLT / AMP METERS :
These meters monitor the battery voltage and charging current of the system. The battery
voltage meter is an expanded scale meter with red, yellow and green indication of state of
charge. These are 5% meters and are intended to give an indication of system status, but are
not designed to give highly accurate readings of voltage and current. The Specialty Concepts
Digital Monitor (DM3) is available if higher accuracy is required.
OPTION P - 50 AMP CHARGE CURRENT :
This option provides 50 amps of charging current capabilities. The terminal accept up to 6
AWG wire. Load ratings and other specifications remain as stated in the specifications.
OPTION T - ADJUSTABLE FULL CHARGE TERMINATION SET-POINT:
DESCRIPTION: - This option allows for the adjustment of the high voltage charge termination
set-point on an SC2 equipped with this option. All other set-points remain fixed, and as
stated in the specifications section. No field calibration is required because the set-points
are switch selected. There are four set-point positions, with values (+ 2%) corresponding
to the following table :
TABLE 1 CONTROLLER SWITCH POSITION
VOLTAGE A B C D
12 VOLT 15.3 14.8 14.3 13.8
24 VOLT 30.6 29.6 28.6 27.6
36 VOLT 45.9 44.4 42.9 41.4
48 VOLT 61.2 59.2 57.2 55.2
The control is factory set at position B. To change the set-point, locate the adjustment
switch. The switch is located on the bottom or top of the control, and can be identified by
the label. Using a slotted screwdriver, turn the switch until the slot is pointing at the desired
position.
SET-POINT RECOMMENDATIONS:
POSITION A: Nicad batteries or for occasional equalization charging
POSITION B: Wet cell lead acid batteries
POSITION C: Sealed maintenance free batteries (heavy use)
POSITION D: Sealed maintenance free batteries (float applications)
