Christie SA10012, SA17512, SA25012 Operating Instructions Manual

IMPORTANT SAFETY INFORMATION

INSTALLATION and OPERATING INSTRUCTIONS

SA Series Chargers (SA10012, SA17512, SA25012)

INSTALLATION

INSPECTION:

Inspect the charger immediately upon receipt. If
there is any damage, call the carrier for an
inspection and file a claim.

APPLICATION:
These chargers are designed to charge groups

of 12 volt batteries connected in parallel. Six
volt batteries may also be charged by
connecting two of them in series (making the
equivalent of a single 12 volt battery).

VENTILATION:

The chargers are designed for continuous duty
use and to provide reliability, the free air
circulation method of cooling is used, (no cooling
fan). Under the circumstances, chargers must
be installed in a well ventilated area and in a
manner so that air flow through the charger is
not restricted. Severe damage may result if air
flow around the cabinet is obstructed.

CAUTION: BE SURE TO DISCONNECT
CHARGER FROM AC SOURCE BEFORE
ENTERING CABINET

CONNECTION TO AC INPUT:

Model SA10012

Measure the voltage of AC power source
available. The charger model SA10012 can be
operated from a nominal 115 volt line (actual
operating range 105 to 125 volts) or a nominal
230 volt line (actual operating range 195 to 255
volts). Factory settings are at 230 volts AC. To
change the AC voltage setting, remove the front
panel and reconnect terminal board as shown
on the wiring diagram furnished with the charger.
Model SA 10012 is furnished with an AC power
cord. Attach a 115 V or 230 V A-C plug to fit
your requirements.

Models SA17512 and SA25012

Measure the voltage of AC power source
available. The charger can be operated from a
nominal 230 volt line (actual operating range 195
to 255 volts) or a nominal 460 volt line (actual
operating range 420 to 510 volts). Factory

settings are at 460 volts AC. To change the AC
voltage setting, remove the front panel and
reconnect terminal board as shown on the wiring
diagram furnished with the charger.

Models SA17512 and SA25012 are designed to
be conduit wired to the AC supply. Connect the
charger to the AC disconnect switch or circuit
breaker with the proper size wire (10 AWG for
230 volt supply, 12 AWG for 460 volt supply).
Remove the back panel and connect wires to
terminals L1, L2, and L3 (if applicable) and
ground on the terminal block mounted near the
AC input conduit fitting.

ADJUSTING DC OUTPUT

Chargers should be adjusted for proper DC
output at time of installation.

CAUTION: BE SURE TO DISCONNECT
CHARGER FROM AC SOURCE BEFORE
MAKING ADJUSTMENTS

SET VOLTAGE BETWEEN 14.8 - 15.2. The
end charge voltage (the voltage which the
batteries approach when fully charged) will then
be 14.4 to 14.8 volts. Batteries will be
recharged in the minimum length of time, require
a minimum of attention and with good batteries
there will be no excessive gassing or
overheating.

Models SA17512 and SA25012

Adjustment taps are provided internally, on the
same terminal board as AC input voltage setting.

With an accurate voltmeter, measure the DC
open circuit voltage (output voltage with the
charger turned on but without batteries
connected) at the ends of the DC cables.

If the voltage is too low, move the adjustment
leads to the right. If the voltage is too high move
the adjustment leads to the left. The coarse
adjustment lead should be moved first to set the
output voltage at or just below the desired
voltage (14.8 - 15.2V). Then move the fine
adjustment lead.

Model SA10012

Adjustment controls are located on front of unit.

With an accurate voltmeter, measure the DC
open circuit voltage (output voltage with the
charger turned on but without batteries
connected) at the ends of the DC cables.

IF AC INPUT IS CONNECTED TO 230 VOLTS,
set open circuit voltage (output voltage with the
charger turned on but without batteries
connected to 14.6 -14.8. Once set, no further
adjustment should be required.

IF AC INPUT IS CONNECTED TO 115 VOLTS,
adjustment of controls may be required at
intervals during charging since most 115 volt AC
lines are not as stable as 230 volt AC lines.
Also, more current is drawn from a 115 volt line,
which may cause an AC voltage drop,
particularly when charging at full output of the
charger. For this reason, connection to a 230
volt AC input is strongly recommended.

When necessary to adjust controls, it is
important to have them set so that DC voltage
will be between 14.6-14.8 when batteries are
substantially charged. Experience in using the
charger will dictate settings, depending on
characteristics of your particular 115 volt AC line
and number of batteries connected.

CHARGING BENCH CONSTRUCTION:

Clore Automotive has available the Christie
Model BR-1 charging rack for 10 batteries.
Multiples of these racks may be connected in
parallel to charge more batteries. You may wish
to construct a charging rack of your own design.
The rack can be constructed to any height,
width, length and configuration desired. Heavy
lumber must be used throughout and with
substantial bracing to prevent swaying. You
must consider the total weight of all batteries to
be charged. Bus bars can be mounted on wood
uprights at the back of the rack or through center
of the rack, which permits batteries to be
charged on both sides. Recommended copper
bus bar minimum size for charging rack is 1/8" x
3/4". Holes must be drilled for mounting of bars
and connecting charging leads.

CONNECTING TO BUS BARS:

WARNING

***CARE MUST BE TAKEN NOT TO
REVERSE CONNECTIONS, WHICH WILL
CAUSE EXTREME SPARKING AT
BATTERY TERMINALS. BATTERY GASES
ARE HIGHLY EXPLOSIVE AND EASILY
IGNITED FROM SPARKING.

***DO NOT STAND OVER BATTERIES
WHILE CONNECTING/DISCONNECTING.

***DO NOT SMOKE OR STRIKE MATCH
AROUND BATTERIES.

***KEEP CHARGING ROOM AND BATTERY
AREA WELL VENTILATED.

***AS BATTERIES ARE ADDED, DO NOT
EXCEED RATED OUTPUT OF CHARGER,
WHICH MAY RESULT IN SEVERE DAMAGE.

Chargers are provided with 10 foot charging
cables terminated with lugs suitable for
connecting to bus bars. The positive cable is
marked with a (+) and the negative cable (-).
When connecting, make sure all surfaces are
clean and connections tight.

BUS BAR TO BATTERY CONNECTION:
Positive and negative leads must be attached to

the bus bars for parallel connection to the
batteries. Christie CL-24 and CL-48 Charging
Leads are recommended for this purpose. They
are supplied in pairs, one positive and one
negative. Leads are #10 wire, 24 or 48 inches
long, with a lug on one end for bolting to the bus
bar and a battery clamp on the other end,
including a color coded insulator (red for
positive, +, pos and black for negative, -, neg).

When connecting leads to bus bars, make sure
all surfaces are clean and connections tight.
Christie type SC18 Series Connectors are
recommended for connecting two 6 volt batteries
in series. Leads are #10 AWG wire, 18 inches
long, with charging clamps and insulators on
both ends.

OPERATION

STARTING TO CHARGE:

Models SA17512 and SA25012

On chargers with 230/460 volts AC input, once
set up, as under "ADJUSTING CHARGER DC
OUTPUT", should not have to be readjusted.

Model SA10012

If connected based on 230 volts AC input, once
set up, as under "ADJUSTING CHARGER DC
OUTPUT", should not have to be readjusted.

If connected based on 115 volts AC input, this
model has coarse and fine adjustment controls
on the instrument panel and may need
adjustments during charging

Charging rate will taper after batteries have been
on charge for a period of time, then more
batteries may be connected, again only until
rated output of charger is reached. For best
performance, minimum number of cells (either 6
or 12 volt batteries) to be connected is:

Model SA10012: 24 cells (4 12V batteries)
Model SA17512: 36 cells (6 12V batteries)
Model SA25012: 60 cells (10 12V batteries)

As battery voltage reaches 14.4-14.8 volts,
charging rate will taper to a very small amount
and batteries should be near full charge. If this
