9. Connecting the sensors

9.1 Connecting to the coil core (figure 1)
The travelling edges (SCE) are connected to the
travelling coil core.
For this purpose, the travelling SCE CLOSING
C O
�ove�ent is connected to connection C o� the
travelling coil core and the optional SCE OPENING
�ove�ent is connected to connection O.
The cable �or the coil core is connected to the SCE
using the supplied cri�p connectors or b�� directl��
soldering the wire to the connectors.
Figure 1: Connection at the coil core
I� a channel is not used, it �ust be connected to an 8.2 k k k W resistor.
9.2 Connecting multiple sensors per sensor circuit (figure 2)
One or �ore 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 may be connected in series, whereby the total cable length must not exceed 25 m.
The length o� one sensor �a�� be up to 25 �.
Be�ore connecting the sensors that are connected in series, it is reco��ended that the resistance
value o� the arrange�ent be �easured.
The resistance �ust be 8.2 kW ± 500 W when the SCE is inactive and �ust not exceed 500 W when
it is active.
ASO sensors must not be connected in parallel.
