Installation
Figure 2 Hard-wiring the Sensor
3.2 Connecting the Sensor to the sc1000
1. Unscrew the protective cover on the controller socket. Retain the protective cover for
the sensor. When the sensor is removed, re-fit the protective cover.
2. Push the connector into the socket. During this process pay attention to the lugs on
the connector.
3. Hand-tighten the union nut.
Note: Do not use the middle connection for the sensors, which is reserved for the display module.
