Regulator Programming Modes
Using The Magnetic Reed Switch
Control of the MC-612-DUAL regulator’s basic and advanced program-
ming modes is provided by a magnetic reed switch located in the upper left
corner of the regulator’s circuit board. The reed switch provides selectable
control of the regulator’s programming without creating an intrusion point as is
common on many other adjustable voltage regulators currently on the market.
A small screwdriver with a magnet embedded in the tip of the handle is included
to activate the magnetic reed switch. While any magnetic tipped tool can be used,
the Balmar programming screwdriver does an excellent job as an interfacing tool.
Programming is accomplished by contacting and removing the magnet from the
RED dot affixed to the regulator’s epoxy potting. If the magnet has difficulty ac-
tivating the reed switch at that position, try moving the up and down along the
length of the reed switch until the RED light is illuminated at the top of the LED
display, between the second and third display digits. The RED light indicates acti-
vation of the the reed switch.
Within the basic and advanced programming instructions, activation of the reed
switch will be described by the following actions:
• TOUCH / RELEASE - Indicates the action of contacting and immedi-
ately removing the magnet from the reed switch
• TOUCH / HOLD - Indicates the action of contacting and holding the
magnet to the reed switch
• TOUCH / HOLD / RELEASE - Indicates the action of contacting and holding the magnet to the reed switch,
then releasing the reed switch be removing the magnet from the RED dot on the epoxy potting
Basic Programming
Programming For Battery Type
The MC-612-DUAL features selectable programs for the following battery technologies; Standard Flooded (FSb), Deep
Cycle Flooded (FdC), gel (gEL), AGM (AgL), Optima (OPS), as well as a factory default program (UFP) and a program for
systems with voltage sensitive halogen equipment (HAL). Programming can be accomplished whenever the regulator is
activated.
System voltage must be greater than 12.5V for programming changes to take place.
When activating the programming mode, keep in mind that the regulator will scroll through the basic programming mode
three times before saving and returning to the operational mode. To adjust the regulator for your battery type:
1. Turn on the regulator. This may be accomplished by turning the ignition switch at the panel to the ON position. If the
regulator’s BROWN ignition wire is connected to an oil pressure switch, it may be necessary to start the engine to
activate the regulator.
2. Once the regulator is on and the display is scrolling, TOUCH / HOLD the magnetic end of the programming screw-
driver to the RED dot on the regulator as described above.
3. Continue to hold the magnet to the RED dot. The letters PRO will appear on the LED.
4. Continue to hold the magnet to the RED dot. The letters BA will appear on the LED.
5. Continue to hold the magnet to the RED dot. The LED display will begin to scroll through the various battery codes.
6. When the desired battery code is displayed, RELEASE the magnet from the RED dot.
7. The display will indicate BA once again. At this point, you have the option to re-enter the battery type mode by re-
applying the magnet to the RED dot. Otherwise, the display will cycle to bEL, indicating entry into the Belt Load Man-
ager mode.
