10 Maintenance / Repair
WARNING
Bodily injury!
The device can be operated at high pressure and with
aggressive media. Any medium that squirts out can cause
severe injuries.
Depressurize the pipeline/tank before opening the
transmitter connection.
NOTICE – Potential damage to device as a
result of electrostatic charging!
When the housing is open, EMC protection is
impaired and there is no longer any protection
against accidental contact.
Do not touch conductive parts of the device.
Corrective maintenance work may only be performed by
trained personnel.
Before removing the device, depressurize it and any adjacent
lines or containers.
Check whether hazardous materials have been used as
materials to be measured before opening the device. Residual
amounts of hazardous material may still be present in the
device and could escape when it is opened.
Within the scope of operator responsibility, check the following
as part of a regular inspection:
— the pressure-carrying walls / lining of the pressure device
— the measurement-related function
— the leak tightness
— the wear (corrosion)
If pressure transmitters are used as intended under normal
operating conditions, no maintenance is required.
It is sufficient to check the output signal at regular intervals (in
accordance with the operating conditions), as described in the
instructions in the section "Operation". If deposits are
expected to accumulate, the measuring equipment should be
cleaned on a regular basis, in accordance with the operating
conditions.
Cleaning should ideally be carried out in a workshop.
10.1 Removal
WARNING – Potential danger if device is
disassembled incorrectly!
Before removing or disassembling the device,
check for hazardous process conditions such as
pressure on the device, high temperatures,
aggressive or toxic media, and so on.
Carefully read the instructions in the ‘Safety’,
‘Mounting’, and ‘Electrical connections’
chapters, and perform the specified steps in
reverse order.
