Maintenance Instructions
1. For flooded lead-acid batteries, regularly check
water levels of each battery cell after charging and
add water as required to level specified by battery
manufacturer. Follow the safety instructions
recommended by the battery manufacturer.
2. Make sure charger connections to battery
terminals are tight and clean.
3. Do not expose charger to oil or to direct heavy
water spraying when cleaning machine.
DC Battery Connection Procedure
:
1. The Green wire outputs a battery voltage when the
charger is not plugged in to AC to provide an
Interlock function.
2. Securely fasten the Black / White ring terminal from
the battery charger to the negative terminal ("-",
"NEG", NEGATIVE") of the battery pack.
3. Securely fasten the Red wire ring terminal from the
battery charger to the positive ("+", "POS",
"POSITIVE") of the battery pack.
4. Select Charge Algorithm if battery type is other than
factory default.
Check / Change Charging Algorithm:
The charger comes pre-loaded with nine algorithms
for Lead Acid batteries as detailed in Table 1. Each
time AC power is applied with the battery pack NOT
connected, the charger enters an algorithm
select/display mode for approximately 11 seconds -
this is the only time the algorithm can be changed. In
this mode, the present algorithm is displayed on the
LED bar graph or 80% LED as shown in Table 1.
If the algorithm # is from one to six, it will be
displayed on the bar graph with the lowest LED
indicating that Algorithm 1 is selected; the second
lowest LED indicates that Algorithm 2 is selected, etc.
For all algorithm #’s, the algorithm number is also
indicated on the 80% LED by the number of blinks
separated by a pause. **
Note- algorithms 7-9 are
indicated only with the 80% LED indication - no bar
graph indication is given.
Check or change the charging algorithm
:
a. Disconnect the positive connector from battery
pack. Apply AC power and after an up/down flash
of the LEDs, the algorithm # will display for 11
seconds.
b. To change algorithm, touch connector during the
11-second display period to the battery pack’s
positive terminal for 3 seconds and then remove-
the algorithm # will advance after 3 seconds.
Repeat until desired algorithm # is displayed. A 30
second timeout is extended for every increment.
Incrementing beyond algorithm 9 moves back to
algorithm 1. After desired algorithm is displayed,
touch the charger connector to the battery positive
until the output relay is heard to click (~10
seconds) algorithm is now in permanent memory.
c. Remove AC power from the charger and
reconnect the charger positive connector to the
battery pack. It is highly recommended to check a
newly changed algorithm by repeating the above
steps a) and c).
