General safety notes
You can find the newest and/or additional information on the CD-ROM
provided, in the handbook, the datasheet, special manuals, certificates
and the download center at www.honeywell.com/ps.
Installation, mounting, commissioning, and maintenance can be
performed only by trained personnel.
Responsibility for suitability and intended use of this instrument rests
solely with the user.
The supplier accepts no liability for inappropriate use by the customer.
Improper installation and operation may lead to loss of warranty.
Moreover, the "general terms and conditions" on the back of the bill
apply, which form the basis for the sales contract.
If you have to send the device back to the manufacturer or supplier, fill
out the form contained on the CD-ROM and enclose it with the device.
Unless this form is completely filled out, it will unfortunately not be
possible for the manufacturer to perform repair or inspection.
Respect general and local electrical safety requirements.

Liquid measurement, prohibited installation locations
CAUTION!
Prohibited: Installing the flowmeter in an upper pipe bend 1, risk
of gas bubbles 2forming!
CAUTION!
Prohibited: Installing the device in a downstream pipe 3or
upstream pipe of a run-out 4.

Liquid measurement, recommended installation locations
CAUTION!
It is absolutely necessary to maintain the required inlet and outlet
runs!
1 Recommended: If the flowmeter is installed in a downpipe, it is absolutely essential to install
a riser pipe immediately after it.
2 Recommended: Installing the flowmeter in an inclined riser pipe.
3 Recommended: Installing the flowmeter in a vertical riser pipe.
4 Recommended: Installing in the bottom pipe bend.

General installation instructions
CAUTION!
Make sure that the connection flanges are sitting concentrically.
On metering points with varying thermal loads the flowmeters are
to be mounted with stress bolts (DIN 2509).
1 Installed length of flowmeter + thickness of gaskets.

VERSAFLOW VORTEX
www.honeywell.com/ps 13
CAUTION!
The inside diameters of the connection pipe flange, of the
flowmeter and of the gaskets must be the same! The gaskets
must not project into the pipe cross-section.
1 Internal diameter connection pipe
2 Internal diameter flange and gasket
3 Internal diameter measuring sensor

Installing instruments in flange design
Install the flowmeter as follows:
•Fix the flowmeter to one side of a flange using bolts and fixing nuts 2.
•Insert the gaskets 1between sensor and flange and align them.
•Check that the gaskets are concentric; they must not project into the pipe.
•Install the gasket, bolts and fixing nuts on the other flange side.
•Align the meter and the gaskets so that they are concentric.
•Now tighten all nuts step by step alternately across the diagonal.

Installing instruments in sandwich design
Install the flowmeter as follows:
•Push the first bolt 3through hole 5of both flanges.
•Screw on the nuts with washers at both ends of the bolt 3but do not
tighten them.
•Mount the second bolt through the holes 4.
•Place the sensor 1between the two flanges.
•Insert the gaskets 6between sensor 1and flanges and align them.
•Check that the flanges are sitting concentrically.
•Install the remaining bolts, nuts and washers. But do not tighten the nuts
yet.
•Turn the centering ring 2anti-clockwise and align the flowmeter.
•Check that the gaskets 6are concentric; they must not extend into the
pipe.
•Now tighten all nuts step by step alternately across the diagonal.

Turning the connection housing
Turn the connection housing as follows
•Switch off the power supply to the flowmeter.
•Loosen the four Allen screws 1on the underside of the converter
housing.
•Lift the converter housing and turn it to the required position in 90°steps.
•Screw the converter housing back on tightly.
DANGER!
All work on the flowmeter electrics may only be carried out by
appropriately trained personnel. The regional occupational health
and safety directives and safety regulations must be observed
without exception.
Do not damage the electrical cable by over tightening.
Do not undo the electrical plug connection.

Turning the LCD display
Turn the display as follows:
•Switch off the power supply to the flowmeter.
•Unscrew the cover in front of the display 1from the converter housing.
•Pull the display 2carefully a few centimetres out of the anchor fitting and
turn it to the required position 3.
•Press the display back onto the spacer pins 4, until it clicks firmly into
place.
•Turn the cover with gasket 5back onto the housing and tighten it by
hand.
INFORMATION!
If the flowmeter is installed in a vertical pipe, you have to turn the
display by 90
° ; if installed below a pipe, turn 180 ° .

Protection category
Therefore it is essential to observe the following points:
•Use only original gaskets that are clean and free of any damage. Defective
gaskets have to be replaced.
•The electrical cables used must be undamaged and must comply with
regulations.
•The cables must be laid with a loop 1upstream of the flowmeter to
prevent water from getting into the housing.
•The cable glands 2have to be tightened firmly.
•Align the meter in such a way that the cable gland is never pointing up 3.
•Close the unused cable glands using blanking plugs 4.
DANGER!
The flowmeter meets the requirements of protection category IP
67.
After all servicing and maintenance work on the flowmeter, the
specified protection category has to be ensured again.

Electrical connections of the signal converter
The following procedures are to be performed:
•Unscrew the housing cover 1of the electrical terminal compartment.
•Connect the device using the standard procedures.
•Pay attention to the correct polarity.
•Connect the grounding 7or 8.
The two grounding points are equally effective from a technical point of
view.
•Lubricate the thread of the cover periodically before closing it.
