7.5 Connecti ng 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. Connecti ng the sensors

8.1 Connecti ng to the coil core SPK 54 (fi gure ��)
The travelling edges (SCE) are connected to the tra-
velling coil core.
For this purpose, the travelling SCE CLOSING movement
is connected to connecti on C of the travelling coil core
and the opti onal SCE OPENING movement is connected
to connecti on O.
If a channel is not used, it must be connected to an 8,2 kΩ resistor.
9.2 Connecti ng multi ple sensors per sensor circuit (fi gure 2)
One or more sensors can be connected to sensor input O or C. For this purpose, the individual sensors are
connected in series according to fi gure 2.
Up to fi ve sensors may be connected in series, whereby the total cable length must not exceed 25 m.
The length of one sensor may be up to 25 m.
Before connecti ng the sensors 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 SCE is inacti ve and must not exceed 500 Ω when it is acti ve.
ASO sensors must not be connected in parallel.

9. Commissioning / functi onal test
The gate system must be tested for proper functi on aft er all of the electrical connecti ons have been established
and the supply voltage has been turned on. To do this, acti vate each of the safety contact edges one aft er
another and check the corresponding reacti ons of the switching unit.
