If there is a need for frequent calibration, make sure that wash is functional and remove the
sensor to check visually that the prism is clean and has not been damaged. Re-install the
sensor and run complete field calibration (see chapter
Entering field calibration parameters
in K-Patents PR-23 Instruction Manual). After this, contact your local supplier.

Operating and Monitoring SD Sensor System
The SD sensor system runs automatically and does not need to be separately operated. If
there are no alarming changes in the diagnostic values or no alarm messages, you do not
need to adjust the operation. The main task of the operator is to make sure that the washes
and steam connections are functioning as they should.

6.1 Preventive Maintenance Plan (PMP)
Preventive Maintenance Plan (PMP) should be adopted in order to prevent bigger
maintenance procedures. Here are the recommended tasks:
Task
Weekly
Annual
Notes
Check the functionality of
diagnostics:
X
See the attached PMI checklist.
CONC (measurement value
of output)
This value should be closely monitored
daily for a week to set the default reading
for weekly inspections
CALC (chemical curve of
calibration)
This is the default reading from the
chemical curve concentration reading set in
calibration, to which you can compare the
CONC values to.
