Reportez-vous au schéma de contrôle 58600-78 du Manuel du contrôleur sc100, Réf. 58600-18 pour connaître les versions des capteurs admises et les conditions d'installation.

1.Route the cable from the sensor through the strain relief in the digital gateway then properly terminate the wire ends (see Figure 5).

Note: Do not tighten the strain relief until the digital gateway is wired and the two halves are threaded securely together.

2.Insert the wires as shown in Table 3 and Figure 6.

3.Make sure the O-ring is properly installed between the two halves of the digital gateway and thread the two halves together. Hand tighten.

4.Tighten the strain relief to secure the sensor cable.

5.Connect the digital gateway to the controller.
