Installation |
|
||
■■ |
When connecting the instrument, the process lines must be free of |
|
|
|
pressure. |
|
|
■■ |
Observe the suitability of the instrument for the media to be |
|
|
|
measured |
|
|
■■ |
Observe maximum pressures |
|
Electrical connection
The instruments are designed to operate with safety extra-low voltage
(SELV).When wiring up the instruments, the technical specifications for those instruments should be followed. In the case of a sensor with 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.
■■ Current/voltage spikes from switching the power supply on or off must be prevented by the customer.
Current consumption
35 mA + switch (7 mA each) + instrument with automatic zero adjustment (20 mA)
0 … 10 V output (10 mA), max. 80 mA

Connection diagram
Relay 1 (standard)
Power supply AC 24 V
Output signal 0 ... 10 V
GB
Relay 2 (option)
If the voltages being switched via the relays are not in accordance with SELV, then the power supply and signal/control cables of the relays should be installed so that they are separated. A separate cable entry is available for both.
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.

Zero point adjustment
|
|
Attention! |
|
|
Connect the voltage supply one hour before making the |
|
|
zero point adjustment. |
GB |
|
|
|
|
|
|
■■ |
Remove both hoses from the pressure connections and . |
|
■■ |
Press both the "up" and "down" buttons simultaneously, or select |
|
|
"Zero" in the setting menu: |
|
|
the green LED switches off and "Zero" is shown in the display. |
|
■■ |
Wait until the green LED switches back on, then reconnect the and |
|
|
pressure connections. |
In normal operation, we recommend that a zero point adjustment is carried out every 12 months.
Span calibration
Attention!
Connect the voltage supply one hour before making the span calibration.
A reference pressure measuring instrument is needed for the span setting.
The span should not be set without pressure being present. If the span is set with either no test pressure, or too-low a pressure, the instrument will lose its accuracy and no longer give correct measured values.
If this should occur, select the menu point "Span" and then select "Reset", in order to reset the span setting.

7.Maintenance and cleaning
The differntial pressure switches are maintenance-free and offer long service life provided they are handled and operated properly.
Clean the instruments with a moist cloth (soap water).
Repairs must only be carried out by the manufacturer or appropriately qualified skilled personnel.
40389228.01 09/2012 GB/D/F/E/I
8.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 countryspecific waste disposal regulations.
