Introduction The Solitel Vibrating Rod Level Switch provides reliable ® level detection of bulk solids and powders. This compact, integral switch is suitable for high or low level detection in hoppers and silos. It may also be used for plugged chute detection.
The SOLITEL switch is mounted to the vessel using a ⁄ " NPT threaded connection. • Ensure that the tip of the probe is located at the desired switching point giving consideration to the slope angle of the material. • The switch may be installed vertically or horizontally (at a downward angle) as shown in Figure 1 on page 3.

2. Use a grounding wrist strap when installing and removing circuit boards. A grounded workstation is also recommended. 3. Handle printed circuit boards only by the edges. Do not touch components or connector pins. 4. Ensure that all electrical connections are completely made and none are partial or floating.

Reference Information Troubleshooting SOLITEL is a simple and reliable device. However, care must be taken to avoid impacting or damaging the vibrat- ing probe. In the event the SOLITEL stops vibrating, the following procedure will identify if the problem is with the electron- ic module or with the sensor: Disconnect the wires going to the sensor.
5. Connect a digital multimeter between points MP5 on the back of the module and ground connection (terminal 3 on the electronic module) or the body of the vibrating probe. See Figure 7 on page 7. 6. Adjust potentiometer P2 on the rear of the electronic mod- ule to obtain a voltage between 0.4 volts and 1.0 volts.
