Balmar MAX CHARGE MC-614 Installation And Operation Manual

1. Programming for Battery Type

Float Voltage. Controls the target voltage for float stage. Adjustment spans from 13.0 to 13.8 volts.

F v

Default is based on battery program selected. To reverse direction of scroll, release magnet and wait for

LED to display Fv code. Re-activate switch and release when desired value is indicated.

Float Time. Controls time setting for float mode. Standard value set is 18 minutes. Settings are from 6

F 1

minutes to 12 hours. To reverse direction of scroll, release magnet and wait for LED to display F1c code.

Re-activate switch with magnet and release when desired value is indicated.

Low Voltage Limit. Allows user control of the regulator's low voltage limit.

Field Threshold - Bulk To Absorption . Controls the criteria used to determine field output re-

quired to maintain calculated bulk charging mode. Factory set at 65% field output. Raising "fba" shortens

calculated bulk charge time. Lowering "fba" increases calculated bulk charge time. Span of adjustment

is 16% to 96%. To reverse direction of scroll, release magnet and wait for LED to display "fba" code. Re-

activate switch and release when desired value is indicated.

Field Threshold - Float To Absorption . Controls the criteria used to determine the field current

F F

threshold required to cycle between absorption and float charging modes. Factory set at 65%. Raising

"ffl" increases calculated float charge time. Adjusted in 1% increments. Span of adjustment is 16% to

96%. To reverse direction of scroll, release "ffl" code. Reactivate switch with magnet and release when

desired value is indicated.

Alternator Temperature Threshold. Controls the setpoint at which point field current is reduced

A L

when the the alternator temperature sensor indicates an over-temp condition at the alternator. Requires

temperature sensor installation. Preset at 108˚.

Battery Temperature Threshold. Controls the setpoint at which point field current is discontinued

B 1

when the the battery temperature sensor indicates an over-temp condition at batteries being sensed.

Requires temperature sensor installation. Preset at 52°C.

Slope Voltage Correction. Adjusts the voltage (in milivolts) the regulator uses when monitoring

S L

battery temperature sensing. Can be custom adjusted to meet the needs of unique battery technologies.

Consult with battery manufacturer for specific slope voltage recommendations.

Battery Equalization

Due to the hazardous nature of equalization (the intentional overcharging of batteries to remove sulfation from the battery

plates) we strongly recommend that the process be done at the dock with a voltage-adjustable shorepower charger. If it is

absolutely impossible to do so, equalization can be done with the alternator and regulator by doing the following:

In Advanced programming, Pra, change the following values.

Cl to a voltage above the desired equalize voltage.

AHL to a voltage above the desired equalize voltage.

Bv to the desired equalize voltage.

Blc to the desired equalize time.

Disconnect ALL battery temperature sensors.

YOU MUST MONITOR THE BATTERIES DURING EQUALIZE PROCESS!

Once the equalization is complete, activate the regulator's basic programming and reset the battery program mode to UFP, and

allow the program to save. Once saved, access the basic programming mode again and reset for the desired battery program.

WARNING: EQUALIZATION IS A MANUAL PROCESS WITH POTENTIAL DANGERS. DO NOT LEAVE SYSTEM UNATTENDED.

Install Positive Battery Sense Wire

(REQUIRED FOR REGULATOR OPERATION)

Included with the MC-614 wiring harness kit is a fused wiring pigtail

which features a ring terminal at one end and a butt connector at the

other. In the center is a 1-Amp ATC-type fuse and fuse holder. This

wire MUST be connected at the (#9) Positive Battery Sense terminal.

A female quick connect plug has been pre-attached on the terminal

#9 pin. To complete installation of the sense circuit:

1. Identify the favored location for battery sensing. In most instances,

the positive output of the alternator, the common side of a battery

switch, or the positive post of the battery being charged will work

best. If the batteries are connected to a battery isolator, the

positive sense wire must be connected to the battery side of the

isolator, preferably at the larger of the battery banks.

2. Attach the included wiring pigtail with 1-amp fuse to a length of wire of sufficient to reach the desired sensing location.

If the length of the wire run between the regulator and the sensing location is 8' or less, a 16-gauge wire is satisfactory.

If the wire run exceeds 8', increase the wire size to 14 gauge.

3. Remove the female 1/4" spade terminal from the terminal #9 pin. Crimp the spade terminal to the sense wire and

reconnect the spade to the #9 terminal pin.

Install WHITE Stator-In And Tach-Out Wires

When an electric tachometer is used, the alternator's stator output will provide the electrical pulse needed to drive the

tachometer. The MC-614 has been designed to provide regulated tach output when the WHITE stator wire is connected

to the regulator's Stator In (#12 in diagram) terminal and the outfeed wire to the electric tachometer is connected to the

Tach Out terminal (#13 in diagram).

Stator output can also be used to detect alternator failure. See Page 6 for details.

When the tachometer is connected via the MC-614, the regulator will ensure that it will not discontinue supplying field

current when the batteries are fully charged. When connecting the tachometer to the alternator stator output, it will be

necessary to determine the number of poles in the alternator in order to properly adjust your tachometer. Most Balmar

alternators feature 12-pole rotors and stators, though, in some cases, the pole count may be 14. See alternator manual for

specifics. See your tachometer manual for adjustment instructions.

Install Battery #2 Temperature Sensor

Your Max Charge MC-614 voltage regulator can accomodate a secondary battery temperature sensor. Used in conjunction

with an optional MC-TS-B battery temperature sensor, the regulator can monitor temperature at a secondary battery bank

and respond to a battery over-temperature condition by discontinuing charging.

To install a secondary battery temperature sensor:

1. Connect the temperature sensor to the secondary battery bank following the directions provided for the primary battery

temperature sensor.

2. Plug the positive and negative sensor to the appropriate positive connector; the BLACK negative sensor wire should

be connected to terminal pin #14. The RED positive sensor wire should be connected to the #15 terminal pin.

Data TX and Data RX

Data TX and RX circuits provide a connection point with outside monitoring equipment. At this time, the Data TX and RX

circuits are only for factory use.

HAL

CAUTION: Reversing the polarity of the terminal connections on any of the alternator or battery

temperature sensors can result in invalid sensing and potential damage to alternators, regulator

14.0

and/or batteries.
