Repair work and Honeywell service work
The device has got hardly any consumables and wear parts. Honeywell recommends that the filter
in the process inlet is checked every year to prevent errors and enable the service calibration to be
completed with special gases.
For security reasons, the service calibration in fiscal mode and some other work may
only be carried out by the manufacturer or by personnel trained or authorized by it.
Please arrange an appointment promptly. This is also an ideal opportunity to rectify any other
discrepancies which occurred during the maintenance work and check the process gas inlet filter.
The instrumentation section may only be opened by trained personnel with the appropriate device
expertise.
If the device is used for fiscal measurements, the presence of a fiscal verification officer or a
representative may also be required if the instrumentation section is opened.
In any case, the following always applies:
DO NOT OPEN WHEN AN EXPLOSIVE ATMOSPHERE IS PRESENT
DISCONNECT POWER BEFORE OPENING
N’OUVREZ PAS L’APPAREIL DANS UNE ATMOSPHÈRE EXPLOSIBLE
DÉCONNECTEZ LA TENSION
AVANT L’OUVERTURE
Please contact Honeywell if the device suffers any damage or to arrange an
appointment for a service visit. The
details are provided at the start
of this document.
Spare and replacement parts for work which you can carry out yourself can also be
ordered from this contact.
The process gas inlet is fitted with a filter to protect the interior of the device from dirt. The filter
is neither visible nor accessible during normal operation. This filter may block and must then be
replaced if gas which does not meet the specifications is supplied or the upstream filter system
fails.
Example:
The message “
Process gas pressure alert
”, although the requirements from
chapter
11 have been satisfied, indicates a possible blockage. In this case, contact Honeywell to conduct
further tests or exclude other causes.
