6.2 Supply voltage

6.6 Connecti ng the safety contact edges to the coil core SPK 54 (fi gure 1)
The travelling safety contact edges are connected to the
travelling coil core
For this purpose, the travelling safety contact edge
CLOSING movement is connected to connecti on C of the
travelling coil core and the opti onal safety contact edge
OPENING movement is connected to connecti on O.
If a channel is not used, it must be connected to
!
an 8,2 kΩ resistor
18
For the voltage supply, either mains voltage (230 V AC 50/60 Hz) or low
!
voltage (24 V AC/DC) may be used The supply line to the switching unit must
be protected with an appropriate fuse
Never apply both voltages simultaneously!
Connect supply voltage 230 V AC to terminals L1 N or 24 V AC/DC to terminals 24
V AC/DC
6.3 Connecti ng the stati onary coil core
Connect the stati onary coil core (for example SPK 55) to terminals Transmit 1 + 2;
no special att enti on is required for polarity
6.4 Connecti ng the stati onary safety contact edges
The stati onary safety contact edge(s) on the leading pillar for the opening
movement is (are) connected to the Stati onary Opening terminal pair If several
safety contact edges are being used, they must be connected in series and the end
edge must be terminated using an 82 kΩ resistor
The stati onary safety contact edge(s) for the closing movement is (are) connected
accordingly to the Stati onary Closing terminal pair
If one or both channels for the stati onary safety contact edges are not used, the
supplied 8.2 kΩ resistors are to be connected to the respecti ve channels
6.5 Connecti ng the control circuits
The control circuit to be monitored for the opening movement (stop-opening
movement) is to be connected to the Stop Opening terminal pair; for the closing
movement (stop closing movement), the appropriate control circuit is to be con-
nected to the Stop Closing terminal pair
The connecti on for the control circuits is permitt ed only for switching
!
low voltages The control circuits are dependent on the rated current
to protect with an appropriate fuse or the rated current to the control
circuits must be limited by other measures to the maximum value
