Battery replacement
• Only use approved battery types. (See Ex-Safety Manual, table in section 6)
• Always replace all of the batteries together.
• Make sure that the polarity of the inserted batteries is correct.
• Please ensure that all used batteries are properly disposed of in an
environmentally friendly manner.
• After changing the batteries or the sealing rings always check to make
sure that the sealing rings and threads are clean and in a good condition.
3.4. Cleaining the rotary switch
A non-contacting rotary switch is used to switch on the Lite-Ex PL 30e (see description
above). Dirt or moisture does not eect the function. The rotary switch is easy to clean if
excessive amounts of dirt and grime have made it dicult to turn. First take o the torch body
and remove the batteries (see section 3.3 Battery replacement). Remove the rotary switch by
sliding it o the back of the torch, and then clean the switch. When putting the rotary switch
back on, make sure that the arrow marks on the ring line up with the alignment screw on the
bottom part of the torch head (see Illustration 1). Then re-insert the batteries, and screw the
body of the torch back on.
3.5. LED replacement
The Lite-Ex PL 30e is equipped with an extremely long-lasting LED lamp. Replacing the LED
is normally not required. If, however, the torch is defective or the brightness of the torch
has diminished, it should be sent to ecom instruments for inspection or repair. Under no
circumstances should you attempt to open the torch head. Manipulating the torch head or
LED on your own poses a risk to the safety of the torch and is not permitted.
3.6. Replacing the spare disc
The torch head is protected by the housing head that surrounds it as well as an additional
disc, which is positioned over the opening where the beam is emitted. The disc is made of
high-quality material. Should, however, the disc break, it is possible to replace it. To replace
the disc, hold on to the body of the Lite-Ex PL 30e and the twist ring, and carefully unscrew
the housing head by turning it anticlockwise. Clean the housing head thoroughly to remove
any remaining pieces, and check the sealing ring for damage. After this has been done, you
can install a new disc and, if necessary, new sealing rings. Only spare sealing rings of ecom
instruments are allowed. The sealing ring is positioned between the housing head and the disc
(see Illustration 1). When putting the housing head back on, ensure that the seal is positioned
properly on the disc. After installation, you should not be able to see any part of the sealing
ring through the opening where the beam is emitted. If the inside of the torch head or lens is
also damaged, the torch should be sent to the manufacturer for repair.
