Inductive signal transmission system

7.5 Connecting the control circuits

The control circuit to be monitored for the opening movement (stop-
7 6
opening movement) is to be connected to terminal pair 4, 5 ; for the
5
4
closing movement (stop-closing movement), the appropriate control
circuit is to be connected to terminal pair 6, 7. 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.

8. Connecting the safety contact edges

8.1 Connecting to the coil core SPK 54 (figure 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 connection C of the travelling
coil core and the optional safety contact edge OPENING
movement is connected to connection O.
If a channel is not used, it must be connected to an 8,2 kΩ resistor.
9.2 Connecting multiple safety contact edges per sensor circuit (figure 2)
One or more safety contact edges can be connected to sensor input O or C. For this purpose, the individual
safety contact edges are connected in series according to figure 2.
Up to five safety contact edges may be connected in series, whereby the total cable length must not exceed 25 m.
The length of one safety contact edges may be up to 25 m.
Before connecting the safety contact edges that are connected in series, it is recommended that the resistance
value of the arrangement be measured.
The resistance must be 8.2 kΩ ± 500 Ω when the safety contact edge is inactive and must not exceed 500 Ω
when it is active.
ASO safety contact edges must not be connected in parallel.

9. Commissioning / functional test
The gate system must be tested for proper function after all of the electrical connections have been established
and the supply voltage has been turned on. To do this, activate each of the safety contact edges one after
another and check the corresponding reactions of the switching unit.
