BATTERY CHARGER ALGORITHM ___________________________________________
Three algorithms are programmed into the Delta-Q
charger. Make sure correct algorithm is set for the
batteries being charged.
Checking Charge Algorithm
1.
Make sure system power switch is in off position and
key is removed.
2.
Disconnect battery pack power connector from
mower.
3.
Disconnect AC cord from wall outlet and charger
receptacle.
4.
Battery Power Modules: Using insulated tools,
disconnect positive lead for charger from battery
pack.
Hybrid Power Modules: Using insulated tools,
connect negative lead for charger to same battery
terminal negative cable for battery connector is
connected to.
All Units: Be careful not to allow positive lead from
charger to contact the mower or other battery
terminals.
5.
Connect charger to wall outlet. Charger will do a
Power On Self Test, then display the algorithm code
by flashing the amber 80% charge led on the left
side of the charger.
The number will flash for the first digit, then a pause,
then the second digit, then a pause, and then repeat
for 11 seconds.
For algorithm 38, the following sequence will flash on
the LED.
Flash - Flash - Flash - Pause - Flash - Flash - Flash -
Flash - Flash - Flash - Flash - Flash - Pause -
Repeat
6.
Disconnect charger from wall outlet.
Changing Charge Algorithm
1.
Follow instructions for checking charge algorithm.
2.
When 80% Charge LED is flashing the algorithm
code, touch the positive lead from charger to
positive battery terminal for 3 seconds, then remove
positive lead. Charger will switch to next algorithm
program in charger.
3.
Touch positive lead to positive terminal until relay
clicks (approximately 10 seconds or more). New
algorithm is now active.
4.
Disconnect AC power cord and positive lead.
Recheck to be certain correct algorithm is active.
WARNING
Use charger only with the algorithm that is appropriate
to the specific battery type. Using incorrect algorithm
may cause personal injury and damage.
Algorithm
Description
11
Used as alternate algorithm for charging
Trojan T890 batteries, but without random
equalization.
38
Default setting for charger. Used for
charging Trojan T890 batteries with random
equalization. Used with battery power
module batteries.
66
Used to charge buffer batteries on hybrid
power modules.
