REGULATOR PROGRAMMING MODES
USING THE MAGNETIC REED SWITCH
Control of the MC-620 regulator’s basic and advanced programming 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 tip 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 activating the reed switch
at that position, try moving it 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 indicated activation of 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 immediately removing the magnet from the reed switch
TOUCH/HOLD - Indicates the action of contacting and holding the magnet to the reed switch
BASIC PROGRAMMING
PROGRAMMING FOR BATTERY TYPE
The MC-620 features selectable programs for the following battery technologies; Standard Flooded (FSb), Deep Cycle Flooded
(FdC), Gel (gEL), AGM (AgL), Optima (OPS), a factory default program (UFP), a program for systems with voltage sensitive
halogen equipment (HAL), and LiFePO
4
(LFP).
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 screwdriver 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
