VI. PRESET BATTERY PROGRAMMING
In addition to its Universal (default) factory program, which can be used safely
with most battery types, the MC-624 features programs for: gel, standard lead
acid, deep-cycle lead acid, AGM (absorbed glass mat), Optima (spiral), as well
as voltage-sensitive (halogen) applications.
The MC-624 is equipped with a magnetic reed switch, embedded in the epoxy
potting, which activates the regulator’s program-
ming. The switch works in two specific actions,
described in the shaded box below:
To set the regulator for your desired battery pro-
gram:
1. ‘ACTIVATE-HOLD’ the switch. The display will
show the
“Pro”
mode, indicating that the
Program mode has been activated.
2. ‘HOLD’ while the display scrolls, until the
numeric equivalent to your battery type is dis-
played on the LED screen. See
Figure 10
to
determine which selectable preset program is
most desirable for your battery technology.
Figure 11
provides detailed information
regarding preset programs.
3. ‘RELEASE’ when the desired value is attained.
4. Once a value has been chosen, the display will return to the
“Pro”
mode. At this point, you can adjust, up or down, by
repeating Steps 1 through 3 until the numeric display reflects your desired preset program.
If no changes are made, the program you have selected will be locked into permanent memory until modified. The
“SAV”
code will be displayed, indicating the program has been locked into memory.

‘ACTIVATE-RELEASE’
Refers to the activation and immediate deactivation of
the switch by lowering a magnetic tool (such as a pocket screwdriver with a
magnetic tip -- see
Figure 9
) onto the upper corner of the switch, and immedi-
ately deactivating the switch by removing the magnet from the switch. An LED
dot, described in Figure 9 will indicate switch activation.
‘ACTIVATE-HOLD ... RELEASE’
Typically used during programming, this
action requires holding the magnet to the switch until desired values are shown
on the display. Once the desired setting is reached, the magnet is removed to
deactivate the switch.
Note: Program function will alternately cycle up or down each time the PrA Mode is acti-
vated. If you miss your desired program value, release the switch and re-activate, the
cycling direction will automatically change. Any advanced programming values will be
retained within the regulator’s memory until the preset battery programming is reset.
