Page 220
The digital I/O ports (Dig I/O) on the pump can be used to exchange
digital signals with external devices. Each port provides one digital input,
one relay output, and one bidirectional input/output.
Figure 74: Digital I/O port
Pin Description
1 Bidirectional input/output
2 Relay output — Relay_NC (Normally Closed contact)
3 Ground — GND
4 Digital input — Input
5 Relay output — Relay_COM
COM is the common contact for NO and NC. If the relay is not activated or if
the pump is turned off, the connection is between COM and NC. If the relay
is activated, the connection is between COM and NO.
6 Relay output — Relay_NO (Normally Open contact)
To use the digital I/O functionality, the following prerequisites must be
fulfilled:
•
The digital I/O port must be connected to the external device with
the appropriate mini-DIN cable (part no. 6036.0006).
1. Plug the 6-pin connector of the cable into the digital I/O port
that you want to use.
The table lists the functions assigned to the connector pins and
the color of the cable wire connected to each pin.
