6. Faults

CAUTION!
Physical injuries and damage to property and the environment
If faults cannot be eliminated by means of the listed measures, the gas
density switch must be taken out of operation immediately.
▶
Ensure that pressure or signal is no longer present and protect against
accidental commissioning.
▶
Contact the manufacturer.
▶
If a return is needed, please follow the instructions given in chapter 9.2
"Return".
For contact details see chapter 1 "General information" or the back page
of the operating instructions.
Faults
Contact is no longer
switching in accordance
with the specification.
Switching status remains
unchanged despite
reaching the switch point/
reset point.
For claims, the serial and product numbers must be stated. The serial number is printed
on the dial, the product number on the product label. With claims, the atmospheric
pressure and the temperature during the measurement must be given, as well as the
data on the reference standard (model, class).

7. Maintenance, cleaning and recalibration

7.1 Maintenance
These gas density switches are maintenance-free.
The switching function should be checked once or twice every year. For this the
instrument must be disconnected from the gas compartment to check with a pressure
testing device (e.g. WIKA BCS-10).
Repairs must only be carried out by the manufacturer.
Causes
Electrical connection is
interrupted.
Electrical load unsuitable for
the switch contact model.
Contact contaminated.
Contacts defective (e.g. fused
contact zone).
Measures
Carry out a continuity test on
the electrical connection lines.
Maintain the permissible
electrical loads for the switch
contact model.
Replace instrument. Before
recommissioning the
new instrument, provide
a protective circuit for the
contact.
