    Before assembly a cut-out must be made to accommodate the device. The sizes and tolerances are given in the technical data. On front of the DI30 are the operating and display elements. On the sides are the fixing elements to mount the device in the panel. On the back are the terminals for all the electrical connections.
  • Page 14 The wall-type housing consists of an upper part and a lower part. A suitable seal has been inserted in the lower part to achieve protection IP 66. In the upper part is the DI30 with its operating and display elements. On the back are the terminals for all the electrical connections.
  • Page 15 3. Connecting cables have to be fed into the enclosure via the PG screws. 4. After connection the upper part of DI30 will be placed on the lower part. Using the four fixing screws, screw the upper part to the lower part. Be sure that the screws are completely tightened in order to attain ingress protection IP66.

  • Page 16: Electrical Connection

    Measuring input for standard signals The input signal is connected to terminals 10 to 12. The DI30 has a voltage input and a current input, to which most conventional sensors with a standard signal output can be connected. The measuring input is galvanically isolated from the power supply (supply voltage) and the transmitter supply.
  • Page 17 This section gives a few examples of practical connections. a) 4…20 mA signal, 2-wire-transmitter b) 0…20 mA signal, 3-wire-transmitter The voltage drop on the transmitter supply wire is irrelevant, which is why this can also be bridged directly on the indicator.

  • Page 18 6 Commissoning, operation c) 0…5 V/0…10 V signal, 3-wire-transmitter The ground is bridged via the sensor, which eliminates the measuring error through the drop in voltage on the transmitter supply wires. WIKA operating instructions digital indicator DI30...

  • Page 26: Description Of Device Parameters

    6 Commissoning, operation 6.6 Description of device parameters The DI30 has a number of unit parameters with which the function of the indicator can be adjusted to the relevant measuring tasks. Because of the large number of these settings and the limited possibility of displaying them on the 7-segment display, the parameters have been given consecutive numbers.
  • Page 27 The parameterised user level PN52 is active as long as the locking code PN51 and the access code PN50 are different. On delivery of the DI30 both parameters are set to 0000, so that the programming lock is deactivated.
  • Page 28 The behaviour of the alarm outputs can be influenced via various program numbers. The data refer to the scaled measurement and are updated with the set measuring time. A description of the various parameters is given in chapter “6.3.4 Description of alarm outputs”. WIKA operating instructions digital indicator DI30...
