Maintenance plan
Maintenance intervals
The equipment operator must specify the maintenance intervals. The period depends on
existing operating parameters such as dust content and state, gas temperature, how the
equipment is run and ambient conditions.
The work to be performed by the operator and execution must be documented in a
Maintenance Manual.
Maintenance contract
Scheduled maintenance work can be carried out by the equipment operator. Only qualified
personnel according to Section 1 should be allowed to do the work. If desired, SICK Service
or authorized Service support centers can carry out all maintenance work. Any repairs will
be made by specialists on-site, whenever possible.
12.4
Consumables and spare parts
Consumables and spare parts for the measuring system are listed in the Spare parts
Section (
).

Maintenance on the sender/receiver unit
Information on sender/receiver maintenance
●
Commissioning and decommissioning, maintenance and cleaning may only be
performed after verification that no explosive gases are present (verification by gas
detector).
●
Check the potential equalization for corrosion, other damage and secure contacts.
●
Check lines for damage and strain relief.
●
Check that the locking parts of the device are firmly locked (laser adjustment opening,
cleaning opening, purge gas connection, hood, plug, sight glass).
●
There is a risk of explosion when pulling the sender/receiver unit out from the duct due
to the hot surface of the measuring probe and possibly escaping hot gases.
Ensure the probe is either cold or the temperature is significantly below ignition
temperature or no Ex atmosphere is present when removing the sender/receiver unit
from the duct.
●
Hot, aggressive or ignitable gas can escape when opening gas paths. Exercise particular
caution and take the necessary safety precautions.
To facilitate device maintenance, SICK offers a set of spare and wear and tear parts. In
addition to the required wear and tear parts for 5 years, this set contains a selection of
small parts that may only be replaced with original parts if lost (
