6. 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.
Attention:
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.
Mind:
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.
Attention:
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.
