Maintenance/Servicing

As far as the maintenance, servicing and
test of electrical apparatus for explosive
atmospheres are concerned, the respective
national regulations in conjunction with the
relevant standards will be applicable!
(IEC 60079-17)
Mind:
Because of the self-discharge of NiMH
batteries, the indication of the battery
capacity should be checked after 2 weeks
and recharged to secure the funktion of the
capacity indication.
"Service" safety function:
The service function serves for recording the
battery state and balancing the battery state's
display by the electronics. This process takes
apx. 36 hours. In case full capacity at any time
is required, we recommend to perform this
service test at 6 months' intervals. The test
should be carried out at about 15°C to 25°C in
order to ensure an accurate calibration of the
display.
Performance of the service:
1. Put the searchlight on charge.
2. Turn the rotary switch to "service" position.
Automatic run of the following processes:
3. The searchlight's battery will be charged.
The display of the charging state (LED's)
shows a travelling light from left to right.
4. Charging being completed, the searchlight
will undergo a controlled discharge via the
main beam lamp. The display of the
charging state (LED's) shows a travelling
light from right to left.
5. The battery state will be memorized.
6. The battery will again be recharged.
Thereat, the display of the charging state
(LED's)
fig. 3) indicates a normal charging process.
If not all LEDs light up at room temperature
after charging is complete, the battery is old
or faulty and must be replaced.
Note:
The more often a service is performed, the
lower the deviation of the charging state's
display will be.
Should the service run be interrupted, e. g.
because of: a defective main bulb, a mains
failure, changing the rotary switch position
(display: green LED's will light, red LED will
pulse), eliminate the fault (e. g. replace main
bulb) and re-initiate the service run.
Lamp replacement:
Lamp replacement may only be performed
in a "non-hazardous area"! The sign lables
with permissible lamps will be visable after
removing the brezel ring.

1. Switch off the searchlight and disconnect
the plug from the mains supply.
2. Unscrew the hexagon socket head screw
(fig. 1, item 7) on the lamphead.
3. Then remove the bezel ring by turning it left
(fig. 1, item 8).
4. Lift the bulb out of the bayonet holder
(main beam lamp: press - turn left - pull)
(fig.1, item 9) (pilot lamp: press - turn right -
pull) (fig.1, item 9).
5. Fit in the new bulb and close the lamphead
in inverse order.
Note:
For focussing the main bulb, there are 3 lock-in
positions provided in the holder.
Take care that the gasket is clean and
undamaged. Check the firm fit of the
hexagon socket head screw.
Battery replacement:
Battery replacement may only be performed
in a "non-hazardous area"! The sign lable
with permissible batteries will be visable
after opening the battery container
1. Switch off the searchlight and disconnect
the plug from the mains supply.
2. The slide on the bottom of the battery
container is pushed back so that the
hexagon socket in the drill hole of the slide
becomes visible (fig. 2, item 1).
3. Using the screw driver joined, unscrew the
hexagon socket head screw and pull off the
battery container.
Avoid short-circuiting!
4. Detach the blue (-) and the yellow (+)
battery lead (fig.2, item 3a/b) as well as the
plug connection (fig. 2, item 4) and remove
the battery set.
5. Fit in the new battery set and connect the
leads, observing the polarity. Blue (-) (fig. 2,
item 3a) and yellow (+) battery lead
(fig. 2, item 3b).
Caution: Do not squeeze leads!
6. Close the searchlight in inverse order.
Mind: Check the tight fit of the hexagon
socket head screw.
7 . Perform a service run as described in para.6.
Note:
Observe the national regulations on waste
disposal.
