5.1 General
Maintenance strategy
The FLOWSIC100 Flare requires scheduled maintenance just like every electronic
measuring system. Regular checks and preventive consumable parts replacement can
lengthen the service life considerably and have a decisive influence on measurement
reliability.
Due to the measuring principle and system design, the FLOWSIC100 Flare only requires a
low maintenance effort despite the customary rugged field usage.
Maintenance work
The work to be carried out is limited to cleaning the sender/receiver units.
Switch the FLOWSIC100 Flare to "Maintenance" mode before starting any maintenance
work. This can be done using an external maintenance switch (connected to digital input
1), using the SOPAS ET operating and parameter program or via the LC-Display option
(
→ pg. 198, § 4.4).
Switch back to "Operation" after completing maintenance work.
Maintenance intervals
The maintenance interval depends on specific application parameters such as mode of
operation, gas composition, gas temperature and moisture as well as the ambient
conditions. Typical values are approx. 6 months up to 1 year. Shorter maintenance intervals
may be necessary under unfavorable conditions.
The plant operator must specify the specific work to be carried out and its performance in a
Maintenance Manual.
Maintenance contract
Scheduled maintenance work can be carried out by the plant 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.
5.2 Recognizing malfunctions
Every deviation from normal operation is to be regarded as a serious indication of a
functional impairment. These are, amongst others:
● Warning displays (e.g. heavy contamination)
● Large drifts in measured results
● Increased power input
● Higher temperatures of system parts
● Monitoring device triggering
● Smells or smoke emission
● Failure of a measuring path
NOTICE:
Proceed as follows when a measuring path fails:
 Pull back the sender/receiver units and disconnect them from the process
by closing the ball valve.
 Inform SICK Customer Service.
