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 rugged, single-piece probe is suitable for use in a variety of powders or granular materials with a minimum bulk density of less than one pound per cubic foot. 1.1 Principle of Operation The Solitel rod vibrates at a 350 Hz frequency. When media makes contact with the rod, the vibration is dampened. The attenuation of the vibration is detected by the integral mount electronics, changing the status of the relay. 2.0 2.1 Installation Unpacking Unpack the instrument carefully. Make sure all components have been removed from the packing material. Inspect all components for damage, and report any concealed damage to the carrier within 24 hours. Check the contents of the carton, making sure it agrees with the packing slip and the purchase order. Verify that the model number imprinted on the nameplate matches the number on the packing slip and the purchase order. Report any discrepancies to the factory. Check and record the serial number for future reference when ordering parts. Serial Number 2.2 Mounting Prior to installation, it is recommended that the unit be calibrated using a sample of the media to be measured. Refer to Calibration, Section 2.5. IMPORTANT: Handle the instrument with great care, especially the probe. Any impact on the probe can damage the vibration system. Figure 1 56-601 Solitel Vibrating Rod Level Switch 3 • • • Figure 2 • The Solitel switch is mounted to the vessel using a 11⁄2" 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. Avoid mounting the sensor in a recess where build-up could dampen the vibration. See Figure 2. Do not cut or bend the vibrating rod. IMPORTANT: A deflection plate is required when the probe is exposed to falling material, collapsed arch, or, in the case of a low level switch, when the drag force of the emptying material exceed the specifications. The deflector can be a baffle plate or angle iron (11⁄2" × 11⁄2" × 1⁄8") located 4 to 6 inches above the rod. See Figure 3. Observe the specifications for bending force(F), torque(M), and pull force(F) as indicated below: See Figure 4. Standard: Extended Rigid: Extended Flexible: F = 100 pounds (445 N) M = 63 foot pounds (85 Nm) M = 63 foot pounds (85 Nm) F = 10,000 pounds (45 kN) Figure 3 VXH VXR VXK F M M Figure 4 F When using an extended length version for low level alarm, mount the probe above the outlet of the vessel to avoid the probe being dragged along by the outflowing material. 2.3 Electrostatic Discharge (ESD) Handling Procedure Magnetrol’s electronic instruments are manufactured to the highest quality standards. These instruments utilize electronic components which may be damaged by static electricity present in most work environments. The following steps are recommended to reduce the risk of component failure due to electrostatic discharge: 1. Ship and store circuit boards in anti-static bags. If an anti-static bag is not available, wrap board in aluminum foil. Do not place boards on foam packing materials. 4 56-601 Solitel Vibrating Rod Level Switch 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. Ground all equipment to a good earth ground wiring. 2.4 Wiring Manually position the housing in the correct direction to allow for easy wiring. The housing can rotate one full turn. Make sure the power supply is turned off. Unscrew and remove housing cover. Connect power leads to the proper terminals. To simplify wiring, the terminal strips may be removed from the module by lifting the front edge of the terminal block. Refer to Figure 5. 120 VAC – Connect the “hot” wire to terminal marked L1 and the “neutral” to terminal L2/N. There is no connection to the center terminal. 1. 2. 3. Figure 5 a. Fail safe jumper LED Sensitivity adjustment b. 240 VAC – Connect one wire to terminal L1 and the other wire to terminal L2/N. There is no connection to the center terminal. c. 24 VDC – Connect wires to terminals (+) and (-). There is no connection to the center terminal. 4. To ensure optimum noise immunity, attach the ground wire to the green grounding screw inside the housing base. Caution: On 24 VDC units, the negative terminal of the power supply is isolated from ground and proper earth grounding of the power supply shield wire is necessary for noise immunity. L1(+) No Connection L2/N(-) Power NO CO NC Relay 5. Connect relay terminals. Refer to Figure 6. 6. Set the fail-safe jumper as described in the table on page 6. For alarm applications, it is recommended that the de-energized status of the relay be used as the alarm status. This allows detection of power failure as an alarm status. 7. Wiring is complete. Replace the housing cover. 8. Apply power to the unit.

The LED will show red when in alarm condition and green when in normal condition. Test the operation of the switch by holding, and then releasing the vibrating rod; the LED will change color. The sensitivity of the switch can be changed using the density adjustment screw. Note that this adjustment screw has 270 degrees of rotation. Do not rotate past the stops. NOTE: If the adjustment is too sensitive, the switch may detect even slight residue of material rather than level. Prior to installation, it is recommended that the unit be calibrated using a sample of the media to be measured. 6 56-601 Solitel Vibrating Rod Level Switch 3.0 3.1 Reference Information Troubleshooting Solitel is a simple and reliable device. However, care must be taken to avoid impacting or damaging the vibrating probe. In the event the Solitel stops vibrating, the following procedure will identify if the problem is with the electronic module or with the sensor: Disconnect the wires going to the sensor. (Terminals 3, 4, and 5). The following gives the expected voltage range between the sensors. Terminals 3 and 4 3 and 5 Voltage 4 to 6 VDC 0.3 to 1.0 VAC If these voltage readings are not obtained, the electronics are defective and need to be replaced. If these voltages are measured, the problem is with the sensor. NOTE: The probe and electronics must be matched to ensure proper operation. Use the following procedure to match the electronics and the vibrating probe: 1. Connect the wires from the sensor to terminals 3, 4, 5. There will be two wires of the same color and one wire of different color. The two similar wires go to terminals 4 and 5; the single wire goes to terminal 3. 2. If the potentiometer is labeled “density” turn to the low position – if labeled “sensitivity” turn to the high position. Note this potentiometer has a 270 degree turn. 3. Apply power to the electronic module. 4. Turn the electronic module over. Front Rear Figure 7 7 56-601 Solitel Vibrating Rod Level Switch 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 module to obtain a voltage between 0.4 volts and 1.0 volts. The reading should be as close to 1.0 volt as possible. 7. Grasp the vibrating section of the sensor with your hand. The vibration should stop and the relay will change state. 8. Remove your hand from the sensor. The relay will change state. 9. The electronic module and probe are now matched. 3.2 Agency Approvals 3.2.1 CSA Model VXX-D1BX-XXX Class II, Div. 1 Type 4X These units have been evaluated to the applicable UL and CSA standards.
