Accessing The Advanced Programming Mode
The MC-612-DUAL provides a broad range of advanced user adjustments in its password-protected Advanced Program
mode. The Advanced Program mode is accessed via the Basic Program mode. To access the Advanced Program mode:
1. With the regulator activated, TOUCH / HOLD the magnet to the RED dot on the regulator’s epoxy potting.
2. The regulator will cycle to PRO. RELEASE the magnet from the switch.
3. The regulator will cycle through all of the Basic Program modes; bA, bEL, Ab2, and dSP -- followed by three dash-
es.
4. TOUCH / HOLD when the three dashes are displayed. The dashes will be replaced by AP0 followed by AP1, and so
on.
5. When the display indicates AP5, RELEASE.
6. The display will cycle to PrA, indicating entry into the Advanced Programming mode.

Making Advanced Programming Adjustments
Once accessed, the Advanced Program mode allows the user to adjust time, voltage and temperature settings for most
operational modes. When the desired mode is indicated, TOUCH / HOLD the magnet to the RED dot on the epoxy pot-
ting. When the reed switch is engaged, the values for the various modes will scroll upward or downward. To reverse the
direction of scroll:
1. REMOVE the magnet from the reed switch.
2. Wait for the mode indicator to be displayed.
3. TOUCH / HOLD when the mode indicator is displayed. The values for that mode will begin to scroll in the opposite
direction. Continue to HOLD until the desired value is displayed.
4. REMOVE the magnet from the RED dot. The mode indicator will be displayed again, followed by the indicator for the
next Advanced Programming mode.
The Advanced Programming Modes are as follows:
Start Delay.
Controls the amount of time from regulator activation to start of charging. Factory
preset at onesecond. Can be adjusted to a maximum of 200 seconds. To reverse direction of scroll,
release magnet and wait for LED to display dlc code. Re-activate switch with magnet and release
when desired value is indicated.
Advanced Program Mode.
Once the correct password has been provided to unlock the Ad-
vanced Program mode, the PrA display will be immediately followed by thirteen advanced control
modes, including; start delay, compensation limit, bulk voltage and time, absorption voltage and
time, float voltage and time, field thresholds, temperature limits and slope.
Compensation Limit.
Controls the maximum limit of allowable system voltage. Starts at value
set by battery program currently in use. Adjustment spans from 14.1 to 15.9 volts. To reverse direc-
tion of scroll, release magnet and wait for LED to display Cl code. Re-activate switch with magnet
and release when desired value is indicated.
High Voltage Limit.
Allows user adjustment of the maximum allowable bulk charging volt-
age. Can be set to a maximum level of 15.6 volts, enabling functions like battery equalization.
WARNING: Extreme caution is required during any high voltage operation. Contact battery
manufacturer for equalization/conditioning protocols for your battery type.
Bulk Voltage.
Controls the maximum limit of allowable bulk voltage. Starts at value set by battery
program currently in use. Adjustment spans from 14.1 to 14.8 volts. To reverse direction of scroll,
release magnet and wait for LED to display bv code. Re-activate switch with magnet and release
when desired value is indicated.
