The output signal is sent from each module for further evaluation via the same route. The power consumption increases by approx. 1 W for each additional module plugged in.

That is to say, on all devices in the system, the same reference potential must be present at the corresponding ground terminal (terminal 2). In the case of a DC supply, ensure correct polarity. ED 3 output signal 0­10 V Pressure transmitters 71 Ty p e s e r i e s F Adjustment and operation Operating ranges and output signals are adjustable over a wide range. An outstanding characteristic of the pressure transmitters is the variability of the characteristic curve, which means that the pressure range and output signal can be adapted to any subsequent control system. P0 = starting pressure of nominal range PN = nominal pressure (end point of nominal range) PA = starting pressure of set range PE = end pressure of set range Operator interface ED 1 1 = Setting spindle for setting the final value PE 2 = Setting potentiometer for setting the initial value PA 3 = Slide switch for selecting the output signal 0­20 mA (0­10 V) or 4­20 mA (2­10 V) 4 = Slide switch for inverting the output signal 5 = Slide switch for changing the steepness of the characteristic in a ratio of 8:5. Normal position: 8 For smaller operating ranges (< approx. 70% of the nominal range), select position 5 6 = Plug connector for further evaluation modules Output signals for module ED 1 Basic setting The factory default setting covers the nominal range P0 (usually 0 bar) to PN. Altering the range The range can easily be altered by shifting the end point and adjusting the steepness of the characteristic curve. Inversion The output signal can be inverted by means of a slideswitch. Operator interface ED 3 1 = Setting spindle for setting the final value PE 2 = Setting potentiometer for setting the initial value PA 4 = Slide switch for inverting the output signal 6 = Plug connector for further evaluation modules Output signals for module ED 3 Range alteration and inversion as above. The current signal can be reduced below 4 mA (down to approx. If the installation has a fault alarm system, the response threshold should be set below 2. 5 mA. 72 Pressure transmitters Ty p e s e r i e s F Setting and testing Altering the operating range To check functioning or change the settings from outside the system, a test set-up is required which meets the following requirements: 1. It must be possible to apply pressure to the pressure transmitter up to the desired final value. The pressure must be displayed by a sufficiently accurate pressure gauge. To display the output signal a voltmeter with a measuring range of 0­10 V (preferably 0­15 V) or an ammeter with a measuring range of 0­20 mA (preferably 0­25 or 0­30 mA) are required. To supply power to the transmitter, a 24 V AC or 24 V DC voltage source is needed. Setting operations must be carried out in the correct sequence 1. Set the slide switches (3) and (4) to the correct position (switch 3 is only present on ED 1) Switch (3): Output signal 0­10 V / 0­20 mA or 4­20 mA / 2­10 V (only on ED 1) Switch (4): Direction of action Switch up rising pressure = rising output signal Switch down (INV): rising pressure = falling output signal 3. [. . . ] A differential pressure must not be active, i. e. Remove the plastic cover and check slide switches 3 + 4. The FHBN is supplied with the correct voltage and the output voltage is displayed. Loosen the spindle locking screw above the inspection window. [. . . ]
