4.3 Battery connection
Before connecting the battery cable, ensure that the battery
voltage complies with the data on the machine plate.
Observe the manufacturer's instructions with regard to
the assignment of battery to charging unit!
Caution!
The charging unit must be correctly connected!
Connect the unit as follows:
1.
red cable (+ terminal) to + terminal of battery, and
2.
black cable (- terminal to - terminal of battery
or
insert the charging plug in the the appropriate socket of
the battery cable if the unit is fitted with a charging
plug.

On-Board-Version
In the on-board version the unit is mounted in a wall cabinet.
Furthermore the following options are included:
a) Protection against start (break of the driving motor) during
the charging process. The change-over contact can be
looped in the traction control circuit and is engaged as fol-
lows:
green = COM (common)
brown = N.C. (normally closed; break-contact)
white = N.O. (normally open; make-contact)
contact rating:
max. 60V/2A/120W
The relay remains energized as long as the unit is switched
on and mains voltage is present.
b) Printed-board coating (the printed boards are coated with a
plastic cover to avoid malfunctions caused by humidity).
c) Mechanics have been shock and vibration tested.

Operation
When the battery is connected, the charging process begins
automatically. The program set is indicated for approx. 10 secs.
by the LEDs flashing. The LEDs which indicate the various
charging programs are given in table 3 of the appendix.
When the battery is fully charged, the charging process is also
ended automatically.
If the charging process is interrupted manually before comple-
tion, the unit must be switched off at switch before disconnect-
ing the battery.

5.1 Function of the LEDs
The functions of the unit are indicated by four LEDs:
Table 1: Function of the LEDs
Battery charger type BC1216, BC1225, BC1235, BC2416, BC2425, BC2450, BC2465
LED 'charge' (yellow)
glows
during the main and gassing charge
phases
flashes
during the equalising charge and
the
second
(charge programs 7 and 15 only) in
combination with LED 'charge
ended'
LED 'charge ended' (green)
glows
after completion of charging
LED 'Fault' (red)
glows
on failure of microprocessor-con-
trolled charging-electronics
flashes in steps of 2 seconds
after forced switchover to gassing
charge
flashes in steps of 4 seconds
in case of overtemperature discon-
nection
LED 'maintenance-free' (yellow)
glows,
if the unit is set for programming
maintenance-free sealed batteries
(pre-set for programs 2 - 6 and 10-
14, for no. 7 and 15 as required)
Caution: maintenance-free batteries
must not be charged if the LED does
not glow!
