SCR2000 CONTROL FEATURES
The automatic equalize features allow for the
consistent application of equalize charges without
constant attention by the operators.
Programmable Cool Down Time
— A programma-
ble cool down feature allows the battery to cool down
for 0 to 8 hours before the charger signals charge
complete. During the cool down period the
alphanumeric display reads “COOL DOWN”. This
feature allows the battery to cool down before being
returned to use and can be used to minimize the
battery maximum temperature during operation.
Extra Run Time
—– The charge time can be ex-
tended past the normal charge termination point
(DV/DT or VT) from 0 to 60 minutes. If equalize has
been selected, any extra run time programmed will
not be added. This feature may be useful in some
abnormal charging situations such as cold storage.
Programmable Recharge Grade –
This feature
allows the same charger and control to charge
batteries at different BCI ratings. Settings for
100D6C8, 80D6C8, and 80D6C10 are available.
Programmable Amp Hour Settings –
Allow the
charger to charge batteries smaller than nameplate
ratings at exactly the correct rate.
Programmable Battery Temperature –
Allows the
charger to charge batteries at correct rates for the
estimated battery temperature.
Programmable Battery Type –
Allows typical
flooded and maintenance free batteries of several
types to be properly charged.
Maximum Charge Temperature –
Pauses the
charge cycle whenever the battery temperature
exceeds the programmed value (BID Module
required).
BID Module Compatibility –
Allows the charger to
automatically read battery size, type, and
temperature before and during the charge cycle and
optimize charging the battery type and conditions.
No Gassing
– A programmable time that effects
how long from the start of a charge cycle before the
gassing portion can begin. If the battery on charge
reaches the finish portion of the curve and the gas-
sing time has not elapsed, the control will interrupt
charging. This minimizes any battery gassing that
may occur during an opportunity charge cycle. Once
the “No Gassing” time has elapsed, the charger will
resume charging at the standard finish rate.
Programmable Start Rate Charging (Extended
AH)
- Batteries of AH rating less than the charger
nameplate AH rating that are equipped with or with-
out a BID module, can be configured for fast charg-
ing at rates from 20 to 50 amps/100AH. This mode
enables fast/opportunity charging for a wide range of
battery ratings. To operate in this charging mode
with a BID installed, program the BID battery type to
8 (function 55) and the BID start amps (function 58)
to the desired charger start rate in amp/100AH. If
operating without a BID, program the charger curve
type to 8 (function 39) and the Battery start amps
(function 57) to the desired charger start rate in
amp/100AH. For example, to charge an 800AH bat-
tery at 320 amps, the “BID Start Amps” would be
programmed to 40A/100AH. Please note that if the
programmed rate exceeds the maximum rated
charger amps, the charger output will be limited to
the maximum current rating.
SCR2000 Charge Archive Function
The archive function allows all 21 items of charge
cycle information to be retrieved and displayed. The
last 99 charge cycles are stored, with the most
recent cycle labeled #1 and earlier cycles labeled in
ascending order.
The most recent charger cycle data is moved to the
#1 archive location when the next battery to be
charged is connected to the charger. At this time the
all previous archive cycle data is shifted to the next
highest archive location (1 to 2, 2 to 3, etc.).
The following key sequence is used to access
charge cycle archive data:

The 19 archive data items are described in detail
below (see Figure 6-2):
AH RETURNED The total ampere-hours returned
during the charge cycle. This
number includes ampere-hours
delivered to the battery during
the 0-80%, 80% to End, and
Equalize portions of the charge
cycle.
CHARGE TIME The total charging time of the
charge cycle. This number
includes the time of the 0-80%,
80% to End, and Equalize
portions of the charge cycle.
