3.4 SPECIAL CONDITIONS OF SAFE USE Before turning on the device, make sure the installation is complete, and there are no visible defects. The device may only be used within the limitations specified in the technical specifications. Protection against electrostatic charge: The devices may partially contain static charging capable plastic components. The presence of electrostatic charges may cause a risk of spark generation and ignition and therefore electrostatic charges must be completely prevented: - Use a shielded cable! - Avoid friction on plastic surfaces! - Do not clean the device dry! For example, use a wet duster! Ex ia ...

4.2 WIRING Shielded and twisted multicore cable is recommended for the electrical connection. For devices with cable gland as well as cable socket, you have to make sure that the external diameter of the used cable is within the allowed clamping range. After you have connected the wires, tighten the gland screw firmly until proper sealing. For the installation of a device with cable outlet following bending radiuses have to be complied with: Cable without ventilation tube: - static installation: 5-fold cable diameter - dynamic application: 10-fold cable diameter Cable with ventilation tube: - static installation: 10-fold cable ...

PROGRAMMING 5.1 OPERATING INFORMATION 5.2 CONFIGURATION The device has, according to the order, max. four LEDs which are allocated to the respective contacts. The LEDs will light up when the respective set point has been reached and the contact is active. Regardless of the number of PNP switches, the structure of the menu system is the same for all types of devices. They differ only by the number of menu items. Following the chart (5.6) an ...

5.3 PASSWORD SYSTEM Your device's menu system can be protected by a password, so it is only possible for an authorized person to make settings. If you activate password access ("PAon"), the entire menu system will be closed. For more information, see "5.7 Detailed menu items". Entering the password will make the entire menu available again, then allow you to change the password at the special menu item 4. In case you forget your password, you can restore the instrument to the factory settings. To do this, use the special menu item 3. 5.4 CONFIGURATION EXAMPLE OF THE ANALOGUE OUTPUT (FOR 4 – 20 mA / 3-WIRE ADJUSTABLE) By the m ...

5.7 DESCRIPTION OF THE MENUSYSTEM Menu 1 – Access protection PAon  password active  to deactivate: set password. PAof  password inactive  to activate: set password. The default setting for the password is "0005"; modification of the password is described in "Special menu 4". Menu 2 – Set decimal point position For devices with 3-wire output 4 – 20 mA and 0 – 20 mA the decimal point was already set during production. Menu 2a – Indication of the start of measuring range (only 4 – 20 mA / 3-wire adjustable) Value defined at order, no input option. Menu 2b – Indication of end of measuring range (only 4 – ...

Menu 35 – Error signal definition (only 4 – 20 mA / 3-wire adjustable) Set the desired error signal (this is given out in case of a defect). Permissible options: "0FF" (no error signal), "C 0" (0 mA or 0 V), "C L0" (3.5 mA or 1.75 V) and "C HI" (23 mA or 11.5 V). The error message appears only when Menu 6 "HILo" is set to "on". Menu 36 – Offset compensation / position correction (only 4 – 20 mA / 3-wire adjustable) Enter the POSI menu; if offset ≠ ambient pressure it is necessary to place the device under pressure pended on mounting position (the pressure reference has to correspond to the zero point of the pressure ...

6. TROUBLESHOOTING Fault Possible causes Fault detection / remedy No output signal: Connected incorrectly. Check the connections! Conductor/wire breakage. Check all wires with cable tester! Defective measuring device (signal input). Check the ampere meter (and its fuse) and the analogue input of the signal processing unit! Analog output signal too low: Load resistance too high. Check the value of the load resistance! Supply voltage too low. Check the power supply and power / current on the transducer / transmitter! Slight shift of the output signal: The diaphragm of the sensor is severely contaminated. Cleaning with non-aggress ...
