Fig. 7.4: Terminal connection diagram on the inside of the controller
The terminal connection diagram indicates the basic functions of the connections.
Connecting the cables to the HPM controller for a particular installation is done after the terminal
assignment, which arises from the SD no. of the selected system diagram (→ Selecting the
System Diagram in HPMtool, P. 65).
The HPM controller has the following connections:
● 1 Input for mains voltage (L) and neutral (N) and ground wire (PE)
● 8 Sensor inputs (terminals 17 – 24); these can also be used as contact inputs
● 7 Potential-free relay outputs (terminals 1, 3, 5, 7, 9, 11, 13)
● 2 Contact/pulse counter inputs (terminals 25, 26)
● 2 Universal 0–10V inputs/outputs (terminals 27, 28)
