Operation; Start-Up - Honeywell VERSAFLOW VORTEX 200 Supplementary Instructions Manual

VERSAFLOW VORTEX 200

5.1 Start-up

Start-up is only permitted when the measuring device:
• is correctly installed in the system and connected.
• has been checked for the proper state with regard to its installation and connection
requirements.
• has been correctly locked to the electronics and terminal compartment.
The electronics and terminal compartment of the vortex flowmeter must be locked during
operation. The covers for the electronics and terminal compartment are secured by a lock.
First manually tighten the covers until the stop. Then loosen the covers (≤ 90°) so that the
lock (special closure) can be secured in the next possible position in the cover.
Use a WS3 Allen key to turn the screw.
No waiting period is necessary prior to opening the housing.
The operator of the system has to check prior to start-up, if the start-up was in compliance with
the national regulations for checks.
If the device needs to be configured due to the existence of an explosive atmosphere, this can be
done using the supplied bar magnets. There is no need to open the housing as it can be done
through the glass window of the electronics compartment or digitally via the signal output
®
(HART interface).

5.2 Operation

Vortex flowmeters must be operated in such a way that they remain within the maximum and
minimum permissible temperatures and pressures and the electrical limit values.
Vortex flowmeters may only be operated if the equipment parts necessary for safety are effective
in the long run, and are not rendered inoperable during operation.
In case of operation with flammable products the measuring units must be included in the
periodic pressure tests of the system.
Opening the signal converter (protection type "flameproof enclosure" or "dustproof housing" or
"terminal compartment in increased safety") in hazardous areas is only permitted in a de-
energised state.
