Maintenance
5.1
General
Maintenance strategy
Just like any other electronic measuring system, the FLOWSIC200 requires regular
maintenance. By inspecting the system regularly and replacing wear-and-tear parts in good
time, the service life of the device can be lengthened significantly and ensures
measurements are always reliable. Due to the measuring principle and system design, the
FLOWSIC200 requires very little maintenance.
Maintenance tasks
Routine maintenance is limited to cleaning system parts from external contamination.
Before carrying out these maintenance tasks, set the FLOWSIC200 to Maintenance mode.
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 (
).
Switch back to “Operation” after completing maintenance work.
Maintenance intervals
Maintenance intervals depend on the local conditions and are therefore to be determined
by the plant operator. As a rule, the maintenance intervals are more than 24 weeks. For
FLOWSIC200 with sender/receiver units FLSE200-H and FLSE200-HM, maintenance
cycles of up to 5 years are possible when used according to specifications.
The work to be carried out by the operator as well as the completion is to be documented in
a Maintenance Manual.
Maintenance agreement
Regular maintenance activities 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. SICK offers a
range of economical maintenance and repair agreements. As part of these agreements,
SICK assumes responsibility for all maintenance activities, repairs are carried out by
specialists on site (as far as possible).
NOTICE:
When replacing components, only use parts that have been approved by SICK!
After all maintenance work, make sure the entire measuring system and any
accessories installed are in a safe condition.
If you have questions, contact the relevant SICK subsidiary.
NOTICE:
The ultrasonic transducers of the FLSE200-M sender/receiver units are
extremely touch-sensitive components.
Avoid direct contact when cleaning (for example clean by careful blowing out,
soft brush; no compressed air).
