For detailed information on terminal assignment, refer to chapter " Terminal
assignment and DIP switches" (→ 2 27).
Connecting a voltage supply
X26:1/2/3 and connector X33 are connected in parallel. The DH.21B/41B option card
in the compact controller is supplied with voltage via X26:6/7.
The DHE21B/41B option card can be supplied with the required voltage by
MOVITRAC
®
B. For this purpose, connect X26:3 (6)/7 with X46:3 (6)/7 or with X12:9/8.
If the DHE21B/41B option card is supplied with DC 24 V from MOVITRAC
®
B, the
functioning of the DHE21B/41B option card is maintained after disconnection from the
power supply. This requires an external DC 24 V supply to X12:8/9 of MOVITRAC
®
B.
