7 Maintenance
The encoder contains no parts that require maintenance.
Do
not
try to repair the encoder yourself. Necessary repairs may only be made by
BAUER or an explicitly-authorized agent.
No change may be made to devices that are operated in areas
subject to
explosion
. Service work may only be performed by specially-trained and authorized
personnel.
When?
What?
Encoder faulty
Change the encoder.
Regularly
Check the encoder for damage.
Ex design: Damage to the device that can compromise the ex-
plosion protection is not permitted – the device must be taken out
of service and it must be ensured that it can no longer be oper-
ated.
Check all seals for possible damage and to ensure their tight fit.
Check all screws, couplings, and clamping elements as well as
cable entries to ensure a tight fit.
Ex design: Check that the guidelines according to EN 60079-19,
EN 60079-17, and EN 61241-17 are adhered to.
(1)
Clean the encoder (see further below).
If necessary
(not Ex)
Change the plug (not component of the scope of supply). Con-
sider that when so doing, you must shorten the length of the con-
nection cable.
Cleaning the encoder
To avoid damage to the encoder, please heed the following points:
– Do not use a high-pressure cleaner.
– If the plug connector has been unplugged, do not allow water, dirt or other sub-
stances to penetrate its open parts.
Clean the encoder with water or a non-corrosive cleanser.

According to these guidelines, the company operating electrical systems in areas subject to explosion is obligated
to have these checked by an electrician to ensure their proper condition.
