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/EN 60079-17)!
Mind:
Because of the self-discharge of NiCd batteries,
the indication of the battery capacity should be
checked after 4 to 6 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 recom-
mend 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.
Lights even after charging ends, at room
temperature, not all LEDs on the battery is to
be substituted aged or defective and needs.
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.

Explosion protected portable searchlight
SEB 8, SEB 8 L, SEB 8 ADR, SEB 8 DIN, SEB 8 L DIN
1. Switch off the searchlight and discon-
nect 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.
Put the new bulb into the best focusing
(usually middle position)
Mind:
Take care that the gasket is clean and
un damaged. 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 discon-
nect 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.
7. Disposal/Recycling
When the apparatus is disposed of, the
respective national regulations on waste
disposal will have to be observed.
In case of disposal you can obtain additional
information from your Cooper Crouse-Hinds/
EATON branch.
Subject to modifications or supplement of the
product range.
