Preamble
The contacts of the DGPT2 are of the changeover type, with a common point, a Normally Closed contact, and a Normally Open contact (see illustration).
The contacts thus enable the user to choose between absent or emission-type operations.
Absent operation (also called negative safety)
For absent operation, the normally closed NC contact of the changeover should be used. This contact opens when the fault occurs. In the device, the output from this contact is always cabled with the blue (common) and red (NC) wires.
Emission operation (also called positive safety)
For emission operation, the normally open NO contact of the changeover should be used. This contact closes when the fault occurs. In the device, the output from this contact is always cabled with the blue (common) and white (NO) wires.
