Circuit diagrams VL1 ... 8 motorized operating mechanism (MO)
You can see the circuit diagrams for the motorized operating mechanism (MO) without
stored energy mechanism below.
The functions of the motorized operating mechanisms are described in the following chapter:
Motorized operating mechanisms (optional) (Page 32)
The isolated contact S3 (terminals 6, 7, 8) is used for scanning the contact position of the
mode selector (switching capacity in accordance with UL 1054: 16 A / 250 V AC; 0.4 A / 125
V DC; 0.2 A / 250 V DC).
With this changeover contact S3, two states of the mode selector can be scanned:
1. Local operation -> "MANUAL" or "LOCAL" position
2. Remote operation -> "AUTO" position
