Connecting cable
Crouse-Hinds
A protective rubber sleeve (page 16, item 13)
mechanically reinforces the connecting cable
at its entry point into the cover.
The positive conductor is marked by a red in-
sulating sleeve. While the positive conductor
is directly screwed onto the spring contact
(page 16, item 10), the negative conductor is
connected to the fuse (page 16, item 11). The
cable and the conductors have to be laid in
acc. with fig. 1.
With closed battery container, the spring con-
tacts (page 16, cover, item 10 and 10A) estab-
lish the electrical connection between the con-
necting cable and the two pole caps of the
battery (page 16, battery container, item 20).
Battery

The battery is composed of three NiCd accu-
mulators with a rated voltage of 1.25 V each.
The capacity is 12 Ah. The accumulators are
built into housings of transparent plastic. The
cover is tightly bonded onto the housing.
Degassing happens via the Kammerhoff valve
via which the accumulator is also topped up
with battery water.
The accumulator cell is marked with the fol-
lowing data:
- manufacturer (not on accumulators of an
older year of manufacture)
- year of manufacture
- upper filling level mark
- bottom filling level mark

The electrolyte is composed of alkaline solu-
tion with special additives. Its density, in op-
eration, lies between 1.15 and 1.21 g/cm³.
Due to the use of special separators with high
absorbing capacity it is possible to operate
the accumulator with a low content of alkaline
solution.

The Kammerhoff vent (fig. 6, page 13) is to
prevent leakage of alkaline solution in any op-
erating position. The charging gases are
evacuated to the outside.
The degassing opening is also used for top-
ping up with battery water.
Type 1229 headpiece with tungsten lamp
The headpiece is also made from plastics. It
houses the tungsten lamp, the glass pane and
the reflector. The tungsten lamp is pressed
against the pane (page 14, item 7) by the
ejecting ring (page 14, item 13) and the pres-
sure spring (page 14, item 12). Should the
glass bulb of the lamp or the glass pane
break, the tungsten lamp will be lifted off the
contact springs (page 14, item 18, 20, 22).
Thereby, the circuit is reliably interrupted.
By turning the switch knob (page 14, item 27),
the functions „ Off-Main beam on-Off-Pilot
light on" can be switched. Below the cap
hook (page 14, item 37), the charging lock is
arranged. The contact bolt (page 14, item 31)
is the second charging contact. While the bat-
tery is on charge, the tungsten lamp must be
switched off.
The locking screw (page 14, item 39) prevents
an unauthorized opening of the headpiece.
The connecting cable is fitted so as to obtain
a distance of approx. 3 mm from the end of
the cable sheath to the inner edge of the cable
entry. The distance between the end of the
cable sheath and the pointed side of the
packing plug is then approx. 10 mm (fig. 4).
The leads are laid downwards at the inner
wall of the housing so that the reflector does
not exert pressure upon them.
Tungsten lamp
The cap light is fitted with a two-filament tung-
sten lamp. The main filament is located in the
focus of the reflector while the secondary fila-
ment is arranged above. The two-filament
lamp provides a high level of safety.
Connecting cable
Two highly flexible leads with a cross-section
of 1 mm² each are spirally wound around a
hemp core, thereby achieving a good flexibility
and high strength. The two leads have a re-
sistant sheath and are fitted with cable termi-
nals.

Basic principle
Via a protective resistor, the battery is charged
at constant potential. With increasing charge,
the battery voltage will rise and the charging
current will drop.
Chargers connected in parallel feed the charg-
ing energy to the charging stations via a
busbar system.
The charging voltage is 5.1 V =.
During the time-controlled fast charge inter-
vals, the charging voltage is raised to approx.
5.5 V =.
Charging rack
The cap lights are charged and kept ready for
use on the charging rack made of sheet steel.
Above the charging stations for the cap lights
there are arranged the box-shaped cross-ties
fitted with ammeters and key-shaped charg-
ing bolts for taking the headpiece. The electri-
cal connection to the headpiece is established
via the charging bolt and the contact spring.
The charging state is indicated by an amme-
ter.

Charging rectifier
The charging rectifiers supply the direct cur-
rent required for charging the batteries.
Input voltage:
230 V, 50/60 Hz
The output voltage can be set from 4.8 V ..5.5 V
with an accuracy of setting of approx. 2 %;
the output current is 120A.
In an overload condition, an electronic control
limits the output current to the rated value by
decreasing the output voltage, thereby pre-
venting an overload of the charger.
Handling and operation of the chargers and
accessory equipment are described in sepa-
rate operating instructions.
