Startup and operation

5.1

Starting up the system

DANGER
Uncontrolled system movement
When starting up, if the position measuring system is part
of a closed loop system whose parameters have not yet
been set, the system may perform uncontrolled
movements. This could result in personal injury and
equipment damage.
► Persons must keep away from the system's
hazardous zones.
► Startup must be performed only by trained technical
personnel.
► Observe the safety instructions of the equipment or
system manufacturer.
1. Check connections for tightness and correct polarity.
Replace damaged connections.
2. Turn on the system.
3. Check measured values (especially after replacing the
BTL). Recalibrate the BTL if necessary.

Operating notes

– Regularly check function of the BTL and all associated
components.
– Take the BTL out of operation whenever there is a
malfunction.
– Secure the system against unauthorized use.
– Observe the directives of the FDA and 3-A SSI, Inc. for
monitoring hygiene and cleaning of the device, as well
as the instructions for operation and maintenance of
the entire system. This especially applies to the
selection of gasket materials, which must be FDA and
3A SIS-conformal, as well as temperature-resistant and
chemically resistant for the cleaning methods applied
and the cleaning and process media used.
– Regularly check the entire device for damage and signs
of wear.
– Regularly check the rod for cracks (e.g. with a color
penetration test) and exchange it if damaged. This
especially applies if the BTL is subjected to heavy
product movements or other mechanical influences.
– Cleaning in place (CIP ) is possible.
1)
– As part of a cleaning validation, the cotter pin and the
float must be removed and checked. Check the holes
in the float and all surfaces that come into contact with
the product for cleanliness and clean them, if
necessary. This also applies to the area near the
welded port. If cleanliness is not achieved, the cleaning
method must be adjusted.
