WARNING
THIS EQUIPMENT CONTAINS LETHAL VOLTAGE LEVELS. INSTALLATION AND SERVICING
MUST BE PERFORMED BY QUALIFIED PERSONNEL

IMPORTANT: SAVE THESE INSTRUCTIONS!

READ AND FOLLOW ALL INSTRUCTIONS BEFORE INSTALLING, OPERATING, OR
SERVICING CHARGER. ANY DEVIATION CAN CAUSE SERIOUS AND PERMANENT DAMAGE.
FAILURE TO FOLLOW THE INSTRUCTIONS VOIDS THE WARRANTY.

1. Install and ground the charger in accordance with the National Electric Code and your local electric
code. Failure to properly ground the charger could result in a fatal electric shock.

2. To reduce the risk of fire, install chargers on a surface of non-combustible material, such as concrete,
stone, brick or grounded metal.

3. This charger has been designed to only charge flooded, lead-acid batteries. It should not be used for
charging other types of flooded batteries or sealed batteries.

4. Connect only batteries of the same number of cells and ampere-hour rating as listed on the charger
nameplate. Damage to the battery could occur, particularly if the battery has fewer cells than the
rating of the charger.

5. Do not touch uninsulated parts of the output connector or battery terminals. A possibility of serious
electrical shock exists.

6. During charge, batteries produce hydrogen gas, which can explode if ignited. Never smoke, use an
open flame, or create sparks in the vicinity of the battery. Ventilate well when the battery is in an
enclosed space.

7. Do not connect or disconnect the battery plug while the charger is on. Doing so will cause arching
and burning of the connector resulting in charger damage or battery explosion.

8. Lead-acid batteries contain sulfuric acid, which is caustic and can cause chemical burns to the skin.
Refer to the battery manufacturers instructions for safe handling of batteries. Use proper personnel
protective equipment. Do not get in eyes, on skin, or on clothing. In cases of contact with eyes, flush
immediately with clean water for 15 minutes. Seek medical attention immediately.

9. Do not operate the charger with the door open or with any panels removed. De-energize all AC and
DC power connections before servicing the charger.

10. The charger is not for outdoor use. Do not expose the charger to water spray, rain or snow.

11. Do not operate the charger with damaged cables, including cables with exposed conductors or
damaged connectors. Replace damaged cables before operation.

SECTION 1 - INSTALLATION

1.1. Receiving

Immediately upon receipt of the charger, check it against the shipping invoice to ensure the shipment is
complete and undamaged.

Examine the outside of the packing for signs of rough handling before accepting the charger from the
carrier.

If there is evidence of damage, the receipt should be signed, and both copies (carrier's and receiving
copies) marked "Shipment Received Damaged". The carrier's representative should be called
immediately and asked to make a "Carrier's Damage Report".

If concealed damage is later detected, the carrier should be called and requested to make a "Carrier's
Inspection for Concealed Damage Report".

After inspection by the carrier, arrangements should be made with the charger representative to have
the charger repaired before placing it in service.

When contacting your charger representative for assistance on a damage claim or shipment error,
provide the Model, and Serial Number of the charger, and a full description of the damage or error.

It is good practice to move the charger to the installation site before uncrating. When using bars,
hammers, etc. for uncrating, use care to avoid damage to the charger.

WARNING: To reduce the risk of fire, install the battery charger on a non-combustible surface
such as concrete, stone, brick, or steel. DO NOT operate the charger on its shipping skid
materials. {

1.2. Location

For the best operating conditions and longest life, take care in selecting an installation site. Avoid
locations exposed to high humidity, temperature extremes or dust. Moisture condensing on machine
parts and electrical components can cause corrosion, which seriously affects operation, efficiency and
life. All units are designed for floor mounting. Standard cases may be stack-mounted if required, up to 3
high. If so, optional stacking brackets are required and available. Consult factory.

Dust and dirt will also decrease heat radiation from heat-generating components, such as transformers and
diodes. This will result in higher operating temperatures and shorter life. Adequate air circulation is needed at
all times in order to ensure proper operation. Provide a minimum of 6 inches of free air space at the sides and
rear of the charger. The front of the charger must remain unobstructed for serviceability.

1.3. Line Voltage Adjustments

All chargers are shipped with the AC line voltage jumper wires set for the AC voltage specified on the
purchase order. Before connecting the charger to the AC service, it should be verified that the internal
AC voltage connections match the available AC service voltage. If necessary change the AC voltage
jumper wires shown in Figs. 1.3.1 through 1.3.3.

NOTE: For 50 Hz. Single or three phase fixed voltage chargers, there are no adjustments.

CAUTION: It will be necessary in most cases to change the AC fuses when the AC voltage jumpers
are changed. Refer to the fuse chart on the inside door of the charger for the correct fuse rating.

• Two conductors and ground wire required for single phase.

• Three conductors and ground wire required for three-phase

1.5. Connecting AC Service to the Charger

1.5.1 Single-Phase Models

Connect the AC service to the L1 and L2 terminals located at the end of the AC fuse block.

Note: If the charger has been ordered with an AC input door-mounted disconnect switch, the AC input
wires will be connected to the L1 and L3 terminals at the top of the switch body.

1.5.2 Three-Phase Models

Connect the AC service to the L1, L2 and L3 terminals located at the end of the AC fuse block.

Note: If the charger has been ordered with an AC input door-mounted disconnect switch, the AC input wires
will be connected to the L1, L2 and L3 terminals at the top of the switch body.

7
1.6 Grounding the Charger

The charger must be grounded to the AC system ground for personnel safety.

The green ground wire in the AC input wiring must be connected to the charger ground stud
(identified by a green dot and ground symbol).

1.7 Battery Connector and Charging Cable

Verify that the connectors on both the battery and the charger are attached so that the positive
output terminal of the charger is connected to the positive battery terminal.

CAUTION: If the polarity is reversed, the DC fuse will blow.

If in doubt, check the polarity with a DC voltmeter.

1.8 Charging Rate Adjustment

Note: Charging rate adjustments may be necessary to compensate for locations of extreme AC line variation
or may be used to tailor the charger output for aging batteries.

The charging rate has been set at the factory; therefore, field adjustment should not be necessary.

If there appears to be a charging rate problem, consult the factory for suggested adjustment.

If it is necessary to either increase or decrease the charging rate, a rate adjustment terminal block is provided
on the top rear of the transformer mounting bracket.

The controlled-ferro charger design utilizes chokes to) control the transformer output. It may be necessary to
adjust the choke tap setting along with the adjustments to the transformer tap settings. The choke tap
adjustment block is located on the choke mounting bracket.

No adjustments should be made without consulting the factory.

 SECTION 2 - OPERATION

2.1 046-0272 Control

The 046-0272 charger control is powered from a 24VAC transformer that provides isolation from the AC service line. The
presence of a battery is detected by the control and causes a charge cycle to begin automatically. The control has
charging profiles that handle standard flooded, gel-cell, and sealed lead-acid batteries, as well as other battery types such
as nickel-cadmium. Each charging profile, or algorithm, uniquely controls the output current and voltage to optimally
charge a particular type of battery, based on battery manufacturer’s recommendations. The control can be set to start
charging at a certain time of day. It can be used with the I’m Cool System and the TOBi® Battery Management System.

The front panel has a 16 character LCD display which normally shows charging amps and volts per cell along with a
periodic message showing the charger state. This display also presents messages if an abnormal charge indication is
detected. A yellow ‘Charging’ indicator lights while the charger is charging. A green ‘Complete’ indicator lights when the
charge is complete. A red ‘Fault’ indicator lights if an abnormal charge indication is detected.
A 16-key keypad allows the user to display various parameters and to customize the operation of the charger.

2.2 PROGRAMMING
A minimum of five parameters must be programmed for proper operation: 1) the time of day and date, 2) the algorithm,
which is determined by the type of battery being charged, 3) the amp-hour rating of the battery which is obtained from the
charger data plate, 4) the nominal battery voltage which is obtained from the charger data plate, and 5) the current shunt
rating which is imprinted on the side of the current shunt located inside the charger. Gather this information before
programming the control.
Press the SET key to enter the programming mode. The display shows ‘SET PARAMETER’. Then another key or keys
are pressed for the parameter to be programmed. The display then shows a brief description of the parameter and its
current value. The parameter is changed by entering a new value using the numeric keys on the keypad. Data entry is
from left to right. If more than four digits are entered, the left-most digits scroll off the left end of the display. If an incorrect
number is keyed in, press 0 four times to scroll the bad number off the display and continue entering the correct value.
(Note that if no keys are pressed within about 8 seconds, the programming mode times-out and the control returns to the
normal ‘#A #.##VC’ display). Once the value is entered, press ) ENTER. If the value entered is correct, the display
shows ‘PARAMETER SAVED’ to confirm the value. (If an incorrect value is entered the display shows ‘!! ERROR !!‘ and
then returns to the normal ‘#A #.##VC’ display.)
Some of the programming parameters can be locked out to prevent a user from intentionally or unintentionally changing
the settings. When a parameter is locked, a lock appears on the display and the value cannot be changed. Refer to the
section on jumper settings for information on locking out parameters.

2.2.1 Setting the Time-of-Day

Press SET, then CLOCK. The display shows ‘TIME OF DAY’ followed by ‘TD:’ and then the time-of-day. Time is
entered in 24 hour format (military time). If the actual time is 3:27 PM, it is entered as 15.27. Enter the correct local
time using the numeric keys on the keypad. Press ENTER to save it.
2.2.2 Setting the Date
The date is set in 3 steps, first the month, then the day, then the year. Press SET, then 5, and then CLOCK. The
display shows ‘MONTH (1-12)’ followed by ‘MO:’ and the month, 1-12. Enter the month using the numeric keys on
the keypad and press ENTER to save it. If the month is accepted, the display then shows ‘DAY (1-31)’ followed by
‘DY:’ and the day-of-month, 1-31. Enter the day using the numeric keys on the keypad and press ENTER to save it.
If the day is accepted, the display then shows ‘YEAR (0-99)’ followed by ‘YR:’ and the year, 0-99. Enter the year
using the numeric keys on the keypad and press ENTER to save it.
2.2.3 Setting the Algorithm
Some algorithms have additional parameters that must be set for proper operation. Refer to table 2 to
determine which algorithm to use for your charger and battery type, as well as any additional parameters
that need to be set. If uncertain about which algorithm to use, contact the factory before attempting to
program the control.
Press SET, then 5, then START. The display shows ‘CHARGE ALGORITHM’ followed by ‘AL:’ and the algorithm
number. Enter the algorithm number using the numeric keys on the keypad and press ENTER to save it.

2.2.4 Setting the Amp-Hour Rating
Press SET, then 0. The display shows ‘BATTERY AH SIZE’ followed by ‘BS:’ and the battery size in amp-hours.
Enter the amp-hour rating using the numeric keys on the keypad and press ENTER to save it.
2.2.5 Setting the Battery Voltage
Press SET, then 5, then 4. The display shows ‘BATTERY VOLTAGE’ followed by ‘VR:’ and the battery rating in volts.
Enter the voltage rating using the numeric keys on the keypad and press ENTER to save it.
2.2.6 Setting the Current Shunt Rating
Press SET, then 5, then 5 again. The display shows ‘SHUNT RATING’ followed by ‘SR’ and the shunt rating in amps.
Enter the shunt rating using the numeric keys on the keypad and press ENTER to save it (if a current sensor is used,
enter 0 for the shunt rating).

2.3 OPTIONAL PARAMETERS

2.3.1 Setting the Cable Resistance
The cable resistance parameter is used to adjust the charger to compensate for extra long charging cables. To set
the parameter, connect a proper sized battery to the charger and allow the charge to start and the current to
stabilize. Press VOLTS twice to display the full battery voltage. Measure the voltage at the battery terminals using a
calibrated DC volt meter. If the readings differ, calculate the resistance as (Vcharger-Vbattery)/current. To change
the setting, press SET, then 3. The display shows ‘CABLE RESISTANCE’ followed by ‘CR:’ and the resistance in
mΩ (milliohms). Enter the new value and press ENTER to save it. Repeat this process as needed until the voltage
readings are the same.
2.3.2 Setting Start Times and Peak Energy Block Out
The control has two different ways to delay the start of a charge cycle. They are the time of day start and delayed
start parameters. The time of day start setting allows the charger to start only at the specified time regardless of
when the battery is connected. The delayed start setting delays the start of the charge the specified amount of time
after the battery is connected (Note: If both parameters are set, the control uses the time of day start). The control
also has energy management settings which allow a peak energy time to be blocked out. If a battery is connected
and charging during this time, the charger turns off and displays ‘ENERGY SAVE ON’. Once the period has ended,
the charger resumes from where it left off. All of these)parameters are grouped together. To set these parameters,
press SET, then START. The display shows ‘TIME OF DAY STRT’ followed by ‘TS:’ and the time of day start setting.
Enter the desired time (99:99 to disable) and press ENTER. The display shows ‘DELAY START TIME’ followed by
‘DS:’ and the delay time. Enter the desired delay time and press ENTER. The display shows ‘ENERGY SAVE ON’
followed by ‘PS:’ and the peak period start time. Enter the desired time of day for the start of the peak period (99:99
to disable) and press ENTER. The display shows ‘ENERGY SAVE OFF’ followed by ‘EP:’ and the peak period end
time. Enter the desired time of day end of the peak period (99:99 to disable) and press ENTER to save it.
2.3.3 Setting the Automatic Watering
The control has the ability to automatically water the battery. A 24VAC solenoid/valve must be installed (refer to
charger schematic) and the battery must have a single point watering system installed. To set the automatic
watering, press SET, then 5, then 1. The display shows ‘WATERING MODE’ followed by ‘WA:’ and the watering
mode setting. Enter the desired mode (0:disable watering, 1:water every charge cycle, 2:water after equalize only)
and press ENTER to save it. If watering is enabled, the display shows ‘WATERING CYCLES’ followed by ‘WC:’ and
the number of watering cycles. Enter the desired number of cycles (each cycle is 15 seconds on and 45 seconds
off) and press ENTER to save it.
2.3.4 Setting Automatic Equalize
The control has the ability to automatically equalize the battery based on the number of cycles or on a specific day of
the week. The equalize cycle can also be delayed a specified amount of time. To set the automatic equalize
parameters, press SET, then 5, then 3. The display shows ‘EQUALIZE CYCLES’ followed by ‘EC:’ and the number
of cycles before equalize occurs. Enter the desired number of cycles (0 to disable) and press ENTER. The display
shows ‘EQUALIZE DAY’ followed by ‘ED:’ and the equalize day. Enter the desired day (0 to disable, 1-7 for Sunday-
Saturday) and press ENTER. The display show ‘DELAYED EQUALIZE’ followed by ‘DE:’ and the equalize delay
time. Enter the desired delay time and press ENTER to save it.
2.3.5 Setting Cool Down Time
The control has the ability to set a cool down time to allow the battery to cool before it is used or to display the
elapsed time to determine the coolest battery. To set the cool down time, press SET, then 5, then 7. The display
shows ‘COOL DOWN TIME’ followed by ‘CT:’ and the cool down time. Enter the desired time and press ENTER. If
a time is set, the display shows ‘COUNT DIRECTION’ followed by ‘TU:’ and the direction. Enter the desired setting
(0:count down, 1:count up) and press ENTER to save it. If the direction is set to count down, the battery ready light
does not come on until the cool down time has elapsed. If the direction is set to count up, the battery ready light
comes on when the charge is complete and the elapsed time since the charge completed is displayed.
CF_13 Page 10 of 25
2.3.6 Setting Automatic Refresh
To set the automatic refresh interval, press SET, then 5, then 8. The display shows ‘REFRESH TIME’ followed by
‘AR:’ and the refresh interval time. Enter the desired interval for automatic refresh (00:00 to disable) and press
ENTER. A refresh consists of 30 minutes of charging at the equalize current.
2.3.7 Setting Charger Alerts
To set the alert parameter, press SET, then 5, then 0. The display shows ‘ALERT ENABLE’ followed by ‘AO:’ and
the alert setting. Enter the desired setting (0:disable alerts, 1:enable alerts) and press ENTER. The display shows
‘ALERT INTERVAL’ followed by ‘AI:’ and the alert interval in seconds. Enter the desired setting and press ENTER.
With alerts enabled, the control displays a message describing the charger state at the set interval.
2.3.8 Setting Automatic Start Mode
To set the automatic start mode, press SET, then STOP. The display shows ‘AUTO START MODE’ followed by ‘AS:’
and the automatic start setting. Enter the desired setting (0: manual start, 1:auto start, 2:auto start on AC) and press
ENTER. If manual start is set, the charger never starts automatically. When the battery is connected, the display
shows ‘CHARGER OFF’. Press STOP to manually start the charge. Also, in manual start mode the charger does
not begin a refresh or automatic equalize cycle once the charger has turned off. If auto start on AC is set, the
charger begins a new charge cycle whenever AC power is removed and restored to the charger. This is useful in
applications where the charger is permanently connected to the battery and a charge cycle is initiated by plugging in
the charger AC power cord.
2.3.9 Setting the Other Parameters
If the charger is part of an I’m Cool system or the TOBi® Battery Management System then the charger identifier (ID)
must be set. This and other additional parameters are programmed in a manner similar to that above. Table 1
describes the parameters and key-strokes used for programming them. When more than one parameter is in the
same row of the table, the control automatically sequences through the additional parameters.

2.4 OPERATION
If alert messages are turned on, periodically a message shows for about 2 seconds in the display. With no
battery connected, the control displays ‘0A 0.00VC’, and a ‘Ferro Magnetics’ message is shown. When
a battery is connected, a lamp test is performed. The charge begins, the yellow CHARGING indicator
lights and the display shows ‘CHARGE PHASE 1’ periodically along with the charging amps and battery
v/c. If equalize is active, an ‘=’ appears on the left side of the display to indicate an equalizing charge.
When phase 1 is completed, the charger starts phase 2 of the charge cycle. The display shows ‘CHARGE
PHASE 2’ along with the charging amps and battery v/c. Depending on the charger and battery type, the
charger may utilize up to 4 phases to complete a charge.
During the equalize portion of the charge cycle the display shows ‘EQUALIZING’ periodically along with
the charging amps and battery v/c.
When a charge is finished, the charger automatically turns off. The display shows ‘BATTERY READY’
and the green COMPLETE indicator lights. The battery may then be disconnected at any time.
2.5 EQUALIZE CHARGE
Over time batteries can develop inequalities in cell charge. This can lower the effective capacity of the
battery and shorten life. An equalizing charge re-balances the charge in the battery cells. Perform an
equalize charge if any of the following conditions exist:
1. On flooded batteries the specific gravity of any cell at the end of charge is 20 points less than the
average of all the cells.
2. The on-charge voltage of any cell at the end of charge is 20 millivolts less than the average of all
the cells.
3. The battery has been stored for 30 days.
The control can perform an equalize automatically based on the number of charge cycles or on a specific
day of the week. Normal equalize consists of an additional 3 hour charge time at the end of a normal
charge cycle.
The control is set at the factory to perform a normal equalize every 7 charging cycles for flooded lead-acid
batteries.
The control can also perform an equalize charge when requested manually. Press the = key. An ‘=’
appears on the left side of the display indicating an equalize charge for the current charge. If no battery is
connected, the equalize occurs on the next charge cycle to allow the cells to equalize their charge.
The auto-equalize or manual equalize charge can be cleared by pressing the = key again. The next auto
equalize charge occurs after the programmed number of charge cycles.

Page 15 of 25
2.6 THERMAL SENSOR OPERATION
The control has the ability to read the battery temperature with an optional thermal sensor. In order for
the sensor to function properly, it must be enabled in the control. This is accomplished by setting the ‘OK
to charge temp’ (OT) parameter to a non-zero value (see table 1). This value indicates the maximum
temperature that allows the charge to start. If the battery is above this temperature when it is connected,
the control displays the temperature and waits for the battery to cool down before starting the charge.
If the thermal sensor is enabled and is missing or damaged, the control displays an F11 indication when
the battery is connected.
The ‘Low charge temp’ (LT) parameter indicates the temperature at which the charge current is reduced
to limit the temperature rise of the battery. The current is reduced proportional to the amount the battery
temperature exceeds the limit.
The ‘No charge temp’ (NT) parameter indicates the temperature at which the charge is terminated. If this
temperature is reached during charge, the charger shuts down and displays an F2 indication.
Refer to the battery manufacturers recommendations before setting these parameters.
If the thermal sensor is enabled, the battery voltage milestones on charge (trip point, cutoff, etc.) are
compensated by 2.5mV/C per degree F (1.5mV/C per degree F for NiCad) above or below 77 degrees F.
If the temperature is below 77 degrees, the voltage is adjusted up and if the temperature is above 77
degrees, the voltage is adjusted down.

2.7 TOBI® PI OPERATION

The control has the ability to communicate with a Tobi® PI battery module. In order for communication to
occur, it has to be enabled in the control. This is accomplished by setting the ‘BC’ parameter (see table
1).
Setting the BC parameter to 0 disables communication.
)
Setting the BC parameter to 1 enables normal communication. While the battery is connected to the
charger, information is transferred between the charger and the Tobi® PI on the battery including the
battery temperature. In order for the charger to utilize the temperature, the temperature sensor must also
be enabled. Refer to the preceding section on thermal sensor operation.
Setting the BC parameter to 2 enables normal communication as well as algorithm upload. In addition to
the information transferred during normal mode, the charger also uploads and utilizes a charge algorithm
from the Tobi® PI on the battery. This can be useful if multiple battery types or AH sizes are used on the
same charger. Refer to the Tobi® PI manual for instructions on setting the charge algorithm. Note: If the
communication between the charger and Tobi® PI fails, the charger utilizes its own algorithm settings to
charge the battery.

SECTION 3 - OPTIONAL FEATURES

3.1 Fusible Door-Interlock Switch (JIC Switch)

The door interlock switch assembly connects the AC service to the charger’s input fuses for each AC line.
The switch is mechanically latched by the door so that it must be in the OFF position before the door can
be opened. Operation of the charger is identical to that of the standard model, except the charger cannot
be energized if the door is open.

3.2 Remote Control

The remote control option makes it possible to operate the charger at a point within 15 feet of the charger.
It includes a box equipped with the control option ordered, and either 15, 20, or 30 feet of jacketed control
harness. Operation is identical to that of a standard charger except that the control is not mounted on the
front of the charger.

3.3 Watering Valve

An optional 24VAC watering solenoid can be ordered. The valve will activate at the end of the charge
cycle. It works in conjunction with an automatic watering system that is supplied by others. Note:
Watering valves have a one year part replacement warranty only.

3.4 Charger Stand
