Response of a protective circuit
After a protective circuit (fuse) has been tripped, attempt to eliminate
the cause of malfunctioning (e.g. replace a defective valve) before
reactivating the protective circuit. Frequent tripping is always due to
an error which, in certain circumstances, may also cause damage to
the instrument.
Malfunctioning/Repairing a defective instrument
The repair of a defective instrument – irrespective of the warranty
period - is only possible when the instrument is dismantled and
returned to us with a description of the error. Please also inform us
about the currently used indicator.
Before you return the instrument for repair work, remove the bottle
and ensure that the measuring chamber has been flushed out and
is empty.
Insert a transportation plug into the outlet pipe to prevent leakage.
Use to the enclosed error log to describe the error and return it to
us together with the instrument. If the error log is no longer
available, download it at www.heyl.de.
