10 Maintenance, calibration
and work on equipment
Interconnection with intrinsically safe circuits
to check or calibrate the equipment inside or
outside hazardous areas is to be performed
only with intrinsically safe current/voltage
calibrators and measuring instruments to
rule out any damage to components relevant
to explosion protection.
Observe the maximum permissible values
specified in the certificates for intrinsically
safe circuits.
10.1 Maintenance
The electronic limit switch does not require
any maintenance when used for its intended
purpose.
DANGER!
Risk of electrostatic charging!
Due to the high surface resistance of
the enclosure cover (R
Isol.
≥ 10 9 Ω),
installation and maintenance on the
equipment must be performed in
such a way as to prevent electrostatic
charging.
Version with integrated solenoid valve
(Type 3738-20-xxx1400xxx000)
There are filters with a 100 µm mesh size in
the pneumatic connections for supply and
output which can be removed and cleaned,
if required.
The maintenance instructions of any up-
stream supply air pressure reducing stations
must be observed.
11 Servicing explosion-protect-
ed devices
If a part of the device on which the explosion
protection is based needs to be serviced, the
device must not be put back into operation
until a qualified inspector has assessed it ac -
cording to explosion protection require-
ments, has issued an inspection certificate or
given the device a mark of conformity.
