Press SET, then 5, then START. The display shows ‘CHARGE ALGORITHM’ followed by ‘AL:’ and the
algorithm number. Enter the algorithm number using the numeric keys on the keypad and press ENTER to save
it.
2.2.2.4 Setting the Amp-Hour Rating
Press SET, then 0. The display shows ‘BATTERY AH SIZE’ followed by ‘BS:’ and the battery size in amp-
hours. Enter the amp-hour rating using the numeric keys on the keypad and press ENTER to save it.
2.2.2.5 Setting the Battery Voltage
Press SET, then 5, then 4. The display shows ‘BATTERY VOLTAGE’ followed by ‘VR:’ and the battery rating
in volts. Enter the voltage rating using the numeric keys on the keypad and press ENTER to save it.
2.2.2.6 Setting the Current Shunt Rating
Press SET, then 5, then 5 again. The display shows ‘SHUNT RATING’ followed by ‘SR’ and the shunt rating in
amps. Enter the shunt rating using the numeric keys on the keypad and press ENTER to save it (if a current
sensor is used, enter 0 for the shunt rating).
2.2.3 OPTIONAL PARAMETERS
2.2.3.1 Setting the Cable Resistance
The cable resistance parameter is used to adjust the charger to compensate for extra long charging cables. To set
the parameter, connect a proper sized battery to the charger and allow the charge to start and the current to
stabilize. Press VOLTS twice to display the full battery voltage. Measure the voltage at the battery terminals
using a calibrated DC volt meter. If the readings differ, calculate the resistance as (Vcharger-Vbattery)/current.
To change the setting, press SET, then 3. The display shows ‘CABLE RESISTANCE’ followed by ‘CR:’ and the
resistance in mΩ (milliohms). Enter the new value and press ENTER to save it. Repeat this process as needed
until the voltage readings are the same.
2.2.3.2 Setting Start Times and Peak Energy Block Out
The control has two different ways to delay the start of a charge cycle. They are the time of day start and delayed
start parameters. The time of day start setting allows the charger to start only at the specified time regardless of
when the battery is connected. The delayed start setting delays the start of the charge the specified amount of time
after the battery is connected (Note: If both parameters are set, the control uses the time of day start). The control
also has energy management settings which allow a peak energy time to be blocked out. If a battery is connected
and charging during this time, the charger turns off and displays ‘ENERGY SAVE ON’. Once the period has
ended, the charger resumes from where it left off. All of these parameters are grouped together. To set these
parameters, press SET, then START. The display shows ‘TIME OF DAY STRT’ followed by ‘TS:’ and the time
of day start setting. Enter the desired time (99:99 to disable) and press ENTER. The display shows ‘DELAY
START TIME’ followed by ‘DS:’ and the delay time. Enter the desired delay time and press ENTER. The
display shows ‘ENERGY SAVE ON’ followed by ‘PS:’ and the peak period start time. Enter the desired time of
day for the start of the peak period (99:99 to disable) and press ENTER. The display shows ‘ENERGY SAVE
OFF’ followed by ‘EP:’ and the peak period end time. Enter the desired time of day end of the peak period
(99:99 to disable) and press ENTER to save it.
2.2.3.3 Setting the Automatic Watering
The control has the ability to automatically water the battery. A 24VAC solenoid/valve must be installed (refer to
charger schematic) and the battery must have a single point watering system installed. To set the automatic
watering, press SET, then 5, then 1. The display shows ‘WATERING MODE’ followed by ‘WA:’ and the
watering mode setting. Enter the desired mode (0:disable watering, 1:water every charge cycle, 2:water after
equalize only) and press ENTER to save it. If watering is enabled, the display shows ‘WATERING CYCLES’
followed by ‘WC:’ and the number of watering cycles. Enter the desired number of cycles (each cycle is 15
seconds on and 45 seconds off) and press ENTER to save it.
2.2.3.4 Setting Automatic Equalize
The control has the ability to automatically equalize the battery based on the number of cycles or on a specific day
of the week. The equalize cycle can also be delayed a specified amount of time. To set the automatic equalize
parameters, press SET, then 5, then 3. The display shows ‘EQUALIZE CYCLES’ followed by ‘EC:’ and the
number of cycles before equalize occurs. Enter the desired number of cycles (0 to disable) and press ENTER.
The display shows ‘EQUALIZE DAY’ followed by ‘ED:’ and the equalize day. Enter the desired day (0 to
disable, 1-7 for Sunday-Saturday) and press ENTER. The display show ‘DELAYED EQUALIZE’ followed by
‘DE:’ and the equalize delay time. Enter the desired delay time and press ENTER to save it.
2.2.3.5 Setting Cool Down Time
The control has the ability to set a cool down time to allow the battery to cool before it is used or to display the
elapsed time to determine the coolest battery. To set the cool down time, press SET, then 5, then 7. The display
shows ‘COOL DOWN TIME’ followed by ‘CT:’ and the cool down time. Enter the desired time and press
ENTER. If a time is set, the display shows ‘COUNT DIRECTION’ followed by ‘TU:’ and the direction. Enter
