6.12.5.2 Connecting a Remote Terminal for Feedback via Digital Signal
Using suitable remote terminals (e.g. optical or acoustic signal generators), the status of the system
can be fed back to you via the pin groups
Digital output 1 , Digital output 2 , and Digital
output 3 of the X2 terminal. Which feedback options were set at the factory for terminal X2 and
its pin groups, is described in a previous section (see Section 6.2, page 26). The feedback options
that you can choose from can be found in the menu
Settings on the user interface of the
Cluster Controller.
Observe the maximum load capacity of the relay contacts
The relay contacts may be loaded with a maximum switching power of 30 W and a maximum
voltage of 48 V
DC
.
Requirements:
☐ The remote terminal must be technically suitable for connection to the digital output (see
Section 9, page 78).
☐ The connection cable must be prepared for connection to the multipole plug (see Section 6.5,
page 30).
