SECTION 3
INTRODUCTION
STEED GEL 100 Industrial Battery Chargers are full wave silicon rectified ferroresonant
chargers.
Charging current and voltage are controlled by the control circuit. This charger is capable of
charging GEL cell batteries.
A solid state, pre-programmed microcomputer provides total control of charge termination,
preventing both undercharging and overcharging. The microcomputer incorporates built in fault
detection to ensure correct battery connection and smooth operation. The charge is terminated
automatically when the control determines that the battery is fully charged.

CONTROL FEATURES
CONTROL FEATURES
Automatic five second delayed start upon connection of a proper sized battery in good
condition.
Battery voltage sensing determines if there is a proper sized battery connected to the
charger. This prevents charging if there is a bad battery, no battery connected, bad batteryto-charger connection or battery voltage and charger mismatch.
Battery voltage and current are continuously monitored and controlled.
Automatic dv/dt charge termination.
Negative battery slope termination to prevent overcharge/thermal runaway.
Automatic 24 hour "REFRESH" charge adds a top off charge to a fully charged battery. The
charger will start a “refresh” charge 24 hours after a normal charge complete has been
reached, assuming that the battery was not disconnected during that time.
Back-up Timers prevent extended charging of a damaged battery. The first timer starts at the
beginning of the charge cycle and runs for 9 hours. If the battery has not reached the gassing
point the charger will shutdown. The second timer starts at the gassing point and runs for a
period of time determined by the charge profile. If the charger has not completed its cycle by
then it will shutdown.
Automatic Shutdown Lock-out will not allow a charge to start after a manual or problem
shutdown occurs. Automatic Shutdown Lock-out is cleared after the "Shutdown" battery is
disconnected. This allows a charge to begin upon connection of a proper sized battery.
Manual STOP switch - Will stop the charger from charging. The display will indicate “OFF”
until the battery is disconnected. When pressed with no battery connected, displays the delay
start setting.
One to nine hour programmable delayed start thumbwheel switch. This rotary switch can be
set from 0 to 9 hours to delay the start of charge.

Equalize switch - This switch when depressed will turn on and off the three-hour additional
equalizing charge. When the equalize function is turned on an “E” will be displayed in the leftmost digit of the display and the CHARGE COMPLETE LED will flash on for 1/2 second and
then off for 3 seconds until the charger goes into the equalize mode. The “E” will flash during
the actual equalize charge cycle.
Refresh mode - When the CHARGING and 80% LED’s light continuously and the CHARGE
COMPLETE LED is flashing the charger is in the refresh mode. The refresh cycle is an
additional charge at the finish rate current. This added charge period will start when the
charger is left connected to a battery for 24 hrs after a normal charge cycle is complete. The
charger will automatically charge at the finish rate current until dv/dt is detected or until the
ceiling voltage limit is reached (Flooded battery only).
Automatic shutdown occurs for any of the following seven failure conditions. The
SHUTDOWN LED will flash when a shutdown occurs.
Manual Jump Start – If the battery voltage is lower than 1.5 V/Cell, the charger can be
manually started by pressing both STOP and EQUALIZE buttons. The charger will shut
down within 5 minutes if the battery voltage does not reach 1.5 V/Cell.
Fault Codes
Fault code “Lo U” - Low volts per cell - the battery voltage is less than 1.5 V/Cell. The
charger will not be “locked off”. The charger will automatically start charging when the
battery voltage is greater than 1.5 vpc.
Fault code “Hi U”-High volts per cell - greater than 2.65, 2.75 or 2.80 vpc (set with 80%
point)
Fault code “dISC” - Battery disconnected from charger during charge.
Fault code “dur ” - Charge time duration exceeded - backup timer expired during “high
rate” charge.
Fault code “Lo I” - Low charging current - charging current less than approx. 3 amps.
Fault code “Hi I” - The charger will shut down for high current if the output current is
imbalanced or over the range for that model.
Fault code “Ph ” (three phase units only) - the incoming AC Voltage has improper
phase rotation. Have a Qualified service person rotate the AC Input phasing to the
charger.
LED Indicators
o “CHARGING” - charger is charging the battery.
o “80%” - the battery voltage is greater than the preset gassing voltage, see section 5.4 for
setting.
o “CHARGE COMPLETE” - the charge cycle has been terminated normally. If flashing slow
(1/2 second every 4 seconds), the charger is set to equalize at the end of the charge
cycle. If flashing on and off each second with the CHARGING and 80% LED’s lit
continuously then the charger is in the refresh mode.
o “SHUTDOWN” - the unit has shut down for a fault.
AMMETER/TIMER Readout will display the following information:
o Charging current
o Fault codes
o Delay start time
o Equalize mode
o Number of charge cycles remaining until the next Auto Equalize mode.
o Amp-Hours returned for this charge cycle.
o Charging time - the length of time the charger was charging.

CHARGER OPERATING PROCEDURE
PRELIMINARY SET-UP:
With all power removed from the charger set the DIP switches per the previous tables before
attempting to charge a battery.
Once power has been applied to the charger, a "dash" will sequence across the display on the
front panel. This indicates the charger is in the "IDLE MODE" of operation, awaiting a battery
connection.
6.2
IMMEDIATE/DELAY START:
The control may be programmed to delay the start of the charge from one to nine hours as well
as an immediate start of the charge upon battery to charger connection. Note: all units are
shipped from the factory set for immediate start (0 hour delay).
If a power failure occurs, no damage will occur to the battery or the charger. If a battery is still
connected when power returns, the GEL 100 will override any delayed start setting and initialize
an immediate start of the charge. Once the charge has been terminated, the delay start will
function normally thereafter.

Remove AC power from the STEED GEL 100 SERIES charger.

Open the charger cabinet door.

Locate the DELAY START thumb-wheel switch behind the front panel at the bottom of the
STEED GEL 100 control board. Adjust the DELAY START thumb-wheel switch until the
NUMBER INDICATOR on the switch yields the number of delay hours desired.

Close and secure the cabinet door.
8
6.3

Apply AC power to the STEED GEL 100 SERIES charger.

Without a battery connected the setting may be checked by pressing and holding the stop
button. Or when a good, proper sized battery is connected to the STEED GEL 100
SERIES charger, the display will indicate the amount of time before the charge is initiated
and the STEED GEL 100 control will begin a countdown to charge.
CHARGING THE BATTERY:
Compare the number of cells and amp-hour capacity of the battery to be charged with the
charger rating found on the charger nameplate. The number of cells in the battery to be charged
MUST match the nameplate data. The amp-hour ratings should also match for timely charging of
the battery. Once the battery to be charged has been determined to match the charger, the
battery may be connected to the charger. The control will measure the average volts/cell of the
connected battery.
If the control has verified the connection of a good battery (between 1.5 and 2.55 volts/cell), the
display will show a countdown to charge initialization and the LED’s will be flashing. When the
countdown reaches zero, the STEED GEL 100 control will start the charging operation.
If the average volts/cell reading is less than 1.5 volts, the display shows “Lo U,” the charge will
not begin and the red SHUTDOWN LED will be flashing. If the battery voltage “floats” above 1.5
vpc the charger will automatically begin a normal charge cycle.
To override the “Lo U” condition press and hold the Stop and Equalize buttons in for ten
seconds. The charger will begin charging. If the battery voltage does not rise above the 1.5 vpc
limit within 5 minutes the charger will be locked off and the override function will not work.
If the average volts/cell is greater than 2.7 volts, display shows “HI U,” The red SHUTDOWN
LED will turn on. Again, the charge will not begin.
Once the charge begins, the display will count down from 9 to 0 then show the output charging
current in amperes. The green CHARGING LED will be on. The chargers offer a three-stage
charge cycle. The Green CHARGING LED will illuminate throughout the charge cycle. The
cycle starts with high rate, constant current.
- For DEKA CHARGING PROFILE, This profile is a two step system with a constant current
then constant voltage. The charger will start in constant current mode of 18 Amps/100 AH until
the battery voltage reaches 2.33vpc (80% point). When the 80% point is reached the charger
changes to constant voltage mode and maintains the battery voltage at 2.33vpc. The charger
will terminate when one of the following conditions is met: (For setting see section 5.4)
 The change in rate of current with respect to time (DI/DT) is met.
 The charging current begins to revise. Negative battery slope.
 The charging current drops below 1.5Amps/100AH
 The charger has run for six hours since reaching the 80% point.
9
- For EXIDE CHARGING PROFILE, This profile is a three step system with a constant current,
constant voltage and then constant current. The stage of charge current is constant at
16A/100 AH until the battery voltage reaches 2.4 V/Cell (80% point). During the second stage
of the charge cycle the battery voltage is held constant at 2.4 vpc until the current drops to
1.5Amps/100 AH. The current is then held constant until six hours has elapsed from the 80%
point. See section 5.4.
6.4
TERMINATION OF CHARGE
MANUAL TERMINATION, while charging, is accomplished by pressing the STOP push-button
switch located on the front panel.
To remove a charging battery from the charger, it is important to press the STOP pushbutton switch first before disconnecting the battery from the charger. Failure to do this
may damage the charger.
When the charge has been terminated due to MANUAL TERMINATION, the red SHUTDOWN
LED will be on solid until the battery is removed. The display will show “OFF.”
PROBLEM SHUTDOWN
Each PROBLEM SHUTDOWN termination is indicated by a flashing red SHUTDOWN LED and
a FAULT code (section 4.1). After the battery is removed, the red SHUTDOWN LED will remain
flashing. The display indicator will remain on until the battery is disconnected from the STEED
GEL 100 SERIES charger. Refer to SECTION 4.1 for a more complete explanation of the
diagnostics.
6.5
THREE HOUR EQUALIZE BUTTON
When the Equalize button is depressed an “E” will appear in the leftmost digit of the display.
When the charger is actually in the equalize mode the “E” will be flashing. The equalize function
can be disabled prior to the start of the equalize cycle by depressing the Equalize button a
second time.
FOR THE DEKA PROFILE The Di/Dt termination will be eliminated and the charger will be allowed to charge for 6 hours
from the 80% point in the constant voltage mode set at 2.33vpc.
FOR THE EXIDE PROFILE The charge will be extended 3 hours in the finish constant current mode.
6.6
AUTO EQUALIZE MODE (if enabled see section 5.4)
The charger will automatically perform the equalize function described in section 6.5.
When this function is enabled, the remaining cycles until automatic equalize occurs can be
checked by pressing the EQUALIZE button with the battery DISCONNECTED.
