For proper operation, the SCR2000 Control must be
set to match the charger in which it is installed.
Cell Size Selection
From the data plate on the charger, note the num-
ber of cells. Place the corresponding DIP switch
(S1) on the SCR2000 Control in the “closed” posi-
tion.

Unique Part Number
Only one of the above DIP switches should be in the
“closed” position at any one time.
For chargers that are rated above 24 cells, a

Full Scale Digital Ammeter Selection
From the data plate on the charger, note the DC out-
put per circuit – Max. Amps. Set S1-7 and S1-8 as
follows:
Amp Hour Jumper
If shipped from the factory with a charger, the correct
amp hour jumper will be installed in the control board.
This jumper resistor tells the control the amp hour
size of charger. If the control is a replacement, be
sure that the amp hour jumper from the replaced con-
trol is installed into the new control. If the jumper is
missing or there is any question, consult the factory.
Single or Three Phase Control Settings
Replacement controls are shipped from the factory
set for use with a three phase charger. If the control
is to be used with a single phase charger, press and
hold the “1” key down while applying power to the
charger and control. When the key is released, the
display should read “1 PHASE”. When a battery is
connected, the control display should read “1
PHASE”. To reset the control for use with a three
phase charger, repeat the process described above,
holding the “3” key down upon power up instead of
the “1” key. When the “3” key is released, the display
should read “3 PHASE”.
