5. Transport, packaging ... / 6. Commissioning, operation

5. Transport, packaging and storage

5.1 Transport

Check the air velocity transmitter for any damage that may have been
caused during transportation.

5.2 Packaging

Do not remove packaging until just before mounting.
Keep the packaging as it will provide optimum protection during
transport (e.g. change in installation site, sending for repair).

5.3 Storage
Permissible conditions at the place of storage:

Storage temperature: -20 ... +70 °C
Protect the instruments from moisture and dust.

6. Commissioning, operation

Installation and mechanical connection

The air velocity transmitter is installed in the duct. The cable for the
supply voltage and the cable for the relay connection (optional) have to
be laid separately, if high voltages (no safety extra-low voltage) are to be
switched with the relay. Both cables have their own cable entry.
The relay parameters have to be set before voltage is connected to the
relay connections. This ensures human safety against electric shock.

The instrument is equipped with a lid xing screw. This screw has to

be used, if the voltage connected to the relay connections is no safety
extra-low voltage.

6. Commissioning, operation

Electrical connection

The instruments are designed to operate with safety extra-low voltage

(SELV). When wiring up the instruments, the technical specications

for those instruments should be followed. In the case of a sensor with

GB

transmitter, as a rule, the transmitter should be operated in the middle
of the measuring range, since deviations can occur at the range limits.
The ambient temperature of the transmitter electronics should be kept
constant.
The transmitters must be operated at a constant operating voltage
(±0.2 V). Current/voltage spikes from switching the power supply on or

o must be prevented by the customer.

6. Commissioning, operation / 7. Options and accessories

Commissioning

A prerequisite for the commissioning is a proper installation of all
electrical supply, control and measuring lines and of the pressure
connection lines. Before commissioning, the leak tightness of the
pressure connection lines must be checked.

The air velocity transmitter is supplied with a special protection cap
protecting the sensitive sensor element against damage during
transport. Before commissioning, this protection cap absolutely must
be removed!

Commissioning of the option with relay

Jumper and pushbutton for the setting of the relay parameters:
Set the jumper "switching point" (sw.p.) and then push the button to set
the desired switching point. The set value (m/s) is shown in the display.

Set the jumper "hysteresis" (hyst.) and then push the button to set the
desired hysteresis of the relay switching point. The set value (m/s) is
shown in the display.

8. Maintenance and cleaning / 9. Disposal

8. Maintenance and cleaning

The air velocity transmitter is maintenance-free and oers long service

life provided it is handled and operated properly.

GB

Clean the instruments with a moist cloth (soap water).

Repairs must only be carried out by the manufacturer or appropriately

qualied skilled personnel.

9. Disposal

Incorrect disposal can put the environment at risk.

Dispose of instrument components and packaging materials in an
environmentally compatible way and in accordance with the country-

specic waste disposal regulations.
