Accessing The Advanced Programming Mode

The MC-624 provides a broad range of advanced user adjustments in its Advanced Programming mode. The Advanced

Programming mode can be accessed at any time via the following steps:

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.

3. Remove the magnet from the switch when the PRO code is displayed.

4. The PrA code will be displayed, indicating entry into the Advanced Programming mode, followed by codes for the

individual Advanced Programming adjustment codes as described below.

5. Re-activate and hold when the desired Advanced Programming adjustment mode is indicated.

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 time from regulator activation to start of charging. Factory preset at one second.

Adjustable to a maximum of 999 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.

Compensation Limit. Controls maximum allowable temperature compensated system voltage. Ad-

justment spans from 28.2 to 31.8 volts. Default is 29.6V. To reverse direction of scroll, release magnet and

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

Bulk Voltage. Controls the target voltage for bulk charge mode. Starts at value set by battery program

in use. Adjustment spans from 28.2 to 29.6 volts. To reverse direction of scroll, release magnet and wait

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

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

minutes to 6 hours. To reverse direction of scroll, release magnet and wait for LED to display b1c code.

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

PrA

Absorption Voltage. Controls the target voltage for absorption charge mode. Starts at value set by

battery program in use. Adjustment spans from 27.8 to 29.4 volts. To reverse direction of scroll, release

magnet and wait for LED to display bv code. Re-activate and release when desired value is indicated.

Absorption Time. Controls time setting for absorption mode. Standard value set is 18 minutes. Set-

tings are from 6 minutes to 6 hours. To reverse direction of scroll, release magnet and wait for LED to

display a1c code. Re-activate switch with magnet and release when desired value is indicated.
