Discharge indication, reading from right to left:
5 green led followed by 3 yellow, then 2 red.
- One red led flashes: 70% discharge.
- Both red leds alternate flash: 80% discharge.
This threshhold is the maximum discharge
acceptable to preserve the performance of the
batteries.
It can be adjusted by a potentiometer located
at the rear of the indicator. It is set at the factory
function of the batteries used and based on
standard operating cycles. The threshhold may
need adjusting if the operating cycle is very
different from the standard cycle (leading to a
faster or slower discharge).
NOTE
The setting can only be modified on a battery
that was submitted to a minimum of 15 charge
- discharge cycles.

To adjust the cut out threshhold, proceed as follows:
- Measure the battery electrolyte density when
the power is cut off (both red leds flash
alternately).
- Adjust the cut out threshhold using the
potentiometer knowing that each letter corrects
the battery electrolyte density by 20 points.
For example, if the potentiometer is set on the
letter L and the electrolyte density of 1,170 kg/
l when the power was cut off:
- The density will be 1,150 kg/l on the next
discharge cycle if the setting is modified to
the letter K.
- The density will be 1,190 kg/l on the next
discharge cycle if the setting is modified to
the letter M.
NOTE
- After any adjustment, check the electrolyte
density at cut off point over several charge/
discharge cycles.
- Trying to "increase" the battery capacity by
exceeding the 80% discharge threshhold will
lead to:
1- malfunctions of the electrical system due
to lack of energy.
2- damage to the batteries at short or medium
term.
