13.1.2 Battery installation
IMPORTANT!
Parameter no. 107must always be checked and adapted to the battery
that is installed in the truck. The parameter settings depend on bat
-
tery type, truck type, battery size and the truck application.
13.1.3 Setting battery parameters
Parameter settings for valve-controlled batteries
(VRLA)
BT recommends that when setting parameter 107in a Reflex truck with
Hawker Evolution batteries, the recommended value for wet batteries
should be reduced by six (6) units.
DANGER!
The battery's service life will be reduced if the value of parameter 107
is set to a value that is too high.
Always check that the parameter set-
tings are correct, using the instructions below as an aid.
When checking the charging state on a discharged 48 V battery, its no-
load voltage should be measured after a rest period. There should be
zero indication in the case of no-load voltage, which should not be less
than 2.02 V/cell or 48.48 V.
See the instructions below.
Instructions for verifying parameter settings
1. Charge the battery.
2. Use the truck in its normal application until the battery indicator
shows a discharged battery (0 % on the display).
3. Disconnect the battery from the truck and let the battery rest for at
least two hours.
IMPORTANT!
Do not charge or discharge during this time.
4. Measure the voltage on the battery at +20 °C. If the voltage is less
than U
end
(see the table below), the parameter value must be re-
duced. A value substantially above U
end
reduces the risk of dam-
age to the battery. At the same time, the operating time of the truck
is reduced. If a longer operating time is required, the parameter val
-
ue can be slightly increased.
5. Each change must be followed by renewed verification of the pa-
rameter setting.
