7.5 Connecting the control circuits

The control circuit to be monitored �or the opening movement (stop‑
opening movement) is to be connected to terminal pair 4, 5 ; �or the
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 �use or the
rated current to the control circuits must be limited b�� other measures
to the maximum value.
8. Connecting the sensors
8.1 Connecting to the coil core SPK 54 (figure 1)
The travelling edges (SCE) are connected to the tra-
velling coil core.
For this purpose, the travelling SCE CLOSING movement
is connected to connection C o� the travelling coil core
and the optional SCE OPENING movement is connected
to connection O .
I� a channel is not used, it must be connected to an 8,2 kΩ resistor.
9.2 Connecting multiple sensors per sensor circuit (figure 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 figure 2.
Up to five sensors ma�� be connected in series, whereb�� the total cable length must not exceed 25 m.
The length o� one sensor ma�� be up to 25 m.
Be�ore connecting the sensors that are connected in series, it is recommended that the resistance value o�
the arrangement be measured.
The resistance must be 8.2 kΩ ± 500 Ω when the SCE is inactive and must not exceed 500 Ω when it is active.
ASO sensors must not be connected in parallel.

9. Commissioning / functional test
The gate s��stem must be tested �or proper �unction after all o� the electrical connections have been established
and the suppl�� voltage has been turned on. To do this, activate each o� the sa�et�� contact edges one after
another and check the corresponding reactions o� the switching unit.
