Mounting Thermatel Flow/Level Switches are shipped assembled to the sensor. Units may be mounted in any position or ori- entation. Refer to Figures 1 and 2. Thermatel Flow/Level Switches should be located to allow easy access for service. During operation the electronics should not be exposed to ambient temperature above +158°... -
Page 6: Wiring
Wiring The wiring connections for the power and relay are suitable for 12–24 AWG wire. Caution: OBSERVE ALL APPLICABLE ELECTRICAL CODES AND PROPER WIRING PROCEDURES. 1. Make sure the power source is turned off. 2. Unscrew and remove housing cover. 3. -

1 through 6. The cable shield should be connect- ed to the green ground screw in the sensor housing. If the cable is supplied by Magnetrol, then this connection is pre-wired at the circuit board. The user only needs to connect the wiring at the terminal connection on the sensor enclosure. -
Page 9: Setup
There are two sets of switches on the TD1/TD2. One set has 4 switches, the second set has two switches. MODEL TD1 The switch settings are set at Magnetrol during setup. Figure 9 Changes in the positions may be required in the field TD1 Connections depending upon the application. -
Page 10: Led Operation
2.5.2 LED Operation TD1 – Two LEDs (Green & Red) • Green LED glows when power is on. • Red LED, glows when an alarm condition exists. The LED operation is independent of relay operation. • The red LED will blink rapidly if the switch detects a fault. It will blink slowly during initial power-on. -
Page 11: Calibration
2.6 Calibration Calibration must be performed using the actual fluid. The switch detects the cooling capabilities of the media. Calibrating the switch in a different media may change the set point. NOTE: Set the switches (Section 2.5.1) to the desired position before performing the calibration. - Page 12 5a. High Level Applications a. Set fail-safe switch to the “HL” position (switch up High Level Adjustment b. Turn alarm potentiometer counterclockwise until red (High Level Fail-safe) LED turns on. c. Turn alarm potentiometer clockwise until red LED turns off. d.

Page 13: Unable To Change Level
2.6.1.1 Unable to Change Level • Low Level: Follow the procedures in Step 5b, steps a–e on page 9. Any change in media will cause a low level alarm indication. • High Level: 1. Ensure that the sensor is located above the level of the fluid. -
Page 14: Adjustment Procedure For High Flow Detection
2.6.3 Adjustment Procedure – HIGH FLOW Detection 1. Place Fail-safe in the “HL” position ( 2. Increase the flow rate to desired alarm point. Allow 3 minutes for the sensor to stabilize. 3. Rotate alarm potentiometer counterclockwise until the red LED turns on. -
Page 15: Advanced Calibration Procedure (Td2)
2.6.4 Advanced Calibration Procedure (TD2 only) Measure and record the voltage between TP1 and TP2. This voltage will change as the set point potentiometer is adjusted. Voltage readings will be between 0 and 5 VDC. This value may be used for future reference or adjustment of set point. -
Page 16: Reference Information
3.0 Reference Information Description Thermatel TD1/TD2 switches are used for flow, level, and interface detection and control. Level detection is accom- plished by sensing changes in the heat transfer characteris- tics of the media. Flow detection is accomplished by sens- ing changes in heat transfer caused by the flowing media. -
Page 17: Fault Detection
Fault Detection The TD1 and TD2 have continuous self diagnostics to ensure the signal from the sensor is within a select range. If the electronics detect an out of range signal, the switch will go into fault mode. In the event of a fault, the red LED will blink and the Unmarked Wires relay will de-energize. -
Page 18: Troubleshooting
Troubleshooting The TD1/TD2 switches have various settings to handle a wide variety of flow and level applications. If the switch is not performing properly, check the switch settings on page 6 or the following: Symptom Application Action Unable to adjust set point to Air Flow Detection Ensure that the probe is extended into the flow obtain alarm... -
Page 19: Maintenance
Maintenance 3.6.1 Cleaning The probe may be cleaned by soaking, spraying solvents or detergent and water onto the sensor tubes, or by ultrasonic cleaning. Lime deposits may be safely removed by soaking in 20% hydrochloric acid. Warming to +150° F (+66° C) is permissible to speed this process. -
