The gauge can also be operated with other controllers.
Especially the fieldbus versions HPG400-SD (DeviceNet) and HPG400-SP
(Profibus) are usually operated as part of a network, controlled by a master or bus
controller. In such cases, the control system has to be operated with the appropri-
ate software and communication protocol (
→ [1] and [2]).
For reasons of compatibility, the expression "sensor cable" is used for all
HPG400 versions in this document, although the pressure reading of the
gauges with fieldbus interface (HPG400-SD or HPG400-SP) is normally
transmitted via DeviceNet or Profibus.
The sensor cable is required for supplying all HPG400 types with power.
In connection with the gauges with fieldbus interface (HPG400-SD and
HPG400-SP), it also permits access to the relay contacts of the switch-
ing functions (
→ 18, 34).
The application and length of the sensor cable have to be considered when deter-
mining the number and cross sections of the conductors (
→ 10).
Open the cable connector (D-Sub, 15 pins, female).
Prepare the cable and solder/crimp it to the connector as indicated in the
diagram of the gauge used:
