VERSAFLOW VORTEX 200
6.1 Maintenance
Maintenance work of a safety-relevant nature within the meaning of explosion protection may
only be carried out by the manufacturer, his authorised representative or under the supervision
of authorised inspectors.
Treat cover threads as necessary with the lubricating paint UNIMOLY C220
For systems in hazardous areas, regular tests are required in order to maintain the proper
condition.
The following checks are recommended:
• Check the housing, the cable entries and the feed lines for corrosion and/or damage.
• Checking the measuring unit and the piping connections for leakage.
• Check the measuring unit and the indicator for dust deposits.
• Including the flowmeter in the regular pressure test of the process line.
6.2 Dismantling
Exchanging the built-in equipment
The dismantling and installation is within the responsibility of the operator.
Due to the modular design of the vortex flowmeters, from a safety perspective, the electrical
equipment built into the signal converter can be replaced with identical spare parts. To do so,
remove the housing cover. Close the housing cover immediately after the spare parts are
exchanged. Ensure that the cover seal is tight.
General notes
Only identical displays or components from the manufacturer may be used.
The device must be de-energised, if it is absolutely necessary to open the flameproof enclosure
or the dustproof electronics compartment in the presence of a potentially explosive atmosphere.
Before connecting or disconnecting the electrical connection cables of the device, make sure
that all cables leading to the signal converter are isolated from the ground of the hazardous
area. This also applies to protective earth (PE) or functional earth (FE) and equipotential bonding
conductors (PA).
Display
The display can be rotated in 90° increments. It is connected to the connector as shown in the
following figure.
Exchanging the signal converter insert
It is permitted to replace the entire VersaFlow Vortex 200 signal converter insert with a brand-
new version identical in type.
