8 54-610 thermatel model td1/td2 flow level switch 2.4.2 remote electronics wiring (td2 only) when using remote electronics, the sensor and electron- ic circuit board are contained in separate enclosures. a six conductor shielded cable is required for connection between the enclosures. the cable is routed to the electronic circuit board and connected to the green, 6-position terminal block (tb4). the cables six conductors are connected to terminals 1 through 6. the cable shield should be connected 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. if cable is supplied by user, remove bezel by placing screwdriver blade in slot in center of bezel and gently pull the handle away from the terminal strips. then remove screws and lift out the electronic module. attach the cable wiring as shown in figure 8. the sensor enclosure includes a 6-position terminal block for connecting a shielded 6-conductor cable. the cables six conductors are connected to terminals 1 through 6 in the sensor enclosure. the cable shield is connected to the green ground screw. refer to figure 8 for the pin numbers. note: the six conductors must be wired so that each terminal on the sensor terminal block tb4 (see figure 8) is connected to its corresponding terminal on the electronic circuit board. failure to do so will cause improper switch operation. 2.4.3 ma output wiring (td2 only) the td2 will output a ma signal which can be used for diagnostics or to provide trend indication from the switch. this ma output represents the sensor signal. the signal cannot be scaled by the user. the output is proportional to the flow rate. the range of outputs will vary for each unit due to differences in probes. the range of the ma output is also dependent upon the switch setting (section 2.5). the ma output can also be used for fault detection. in the event of a fault, the ma output will be greater than 22 ma if hlfs is selected or less than 3.6 ma if llfs is selected. the ma output is isolated from the input power. wiring of the ma output is shown in figure 7 on page 6. wiring should be 16 to 26 awg. note: due to atex requirements, the ma output is not provided on the td2-xd0x-xcx. sensor enclosure figure 8 1 6 tb4 123456 1 - white 2 - black 3 - red 4 - green 5 - orange 6 - blue shield td2 electronics
9 54-610 thermatel model td1/td2 flow level switch 2.5 setup 2.5.1 switch settings the td1 and td2 have a series of switches which may require field adjustment depending upon the application. switch position for the td1 is shown in figure 9 and switch position of the td2 is shown in figure 10. there are two sets of switches on the td1/td2. one set has 4 switches, the second set has two switches. the switch settings are set at magnetrol during setup. changes in the positions may be required in the field depending upon the application. there is a tag wired onto the switch which indicates the default settings. see figure 11. use the following table for recommended switch settings. switch purpose options heater control heat to sensor see sensor table below default is + temperature compensation on/off see sensor table below default is on media gas/liquid select default is liquid l use gas g position only for gas flow applications range expand sensitivity for water flow applications switch to e position for water flow applications to improve sensitivity default is s sensor application heater tempcomp media spherical tip (txa, txb) liquid flow + on l gas flow +* on g level - on l twin tip (txc, txd) liquid flow + on l gas flow +* on g level - on l hthp (txh) liquid flow + on l gas flow + on l** level - on l flow body (txl) liquid flow + on l gas flow + on l* fail-safe hl = high level fail-safe ll = low level fail-safe fault detection should be on (some applications may require that this be turned off, see section 3.5). four-position switch two-position switch sensor figure 9 td1 figure 10 td2 figure 11 td1/td2 setup tag power heater temp comp media range failsafe fault o f f g a se o n ls i l l o n q h l o f f alarm model td1 nc c no nc c no time delay alarm model td2 nc c no nc c no tp2 tp1 l2 l1 * applications at no flow or low flow should be set with heater to -. ** for best results use l setting for hthp probe and low flow body.
10 54-610 thermatel model td1/td2 flow level switch 2.5.2 led operation td1 C 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. td2 C four leds (red, yellow, & 2 green) leds indicate alarm status and fault indication. the led operation is independent of relay operation. ? red led glows when an alarm condition exists. it will blink if the switch detects a fault. ? yellow led glows when approaching an alarm condition ? green leds glow as the actual condition is further away from the alarm set point. this represents a safe mode. 2.5.3 led initialization the td1/td2 has an initializing period to allow the sensor to heat up. td1 C the red led will blink slowly during the initial- ization period. td2 C all leds will turn on then individually turn off. when complete the td2 will resume normal operation. 2.5.4 time delay (td2 only) turning the time delay potentiometer clockwise increases response time. this adjustment adds time delay in addi- tion to the sensor response time. generally this is set to full counterclockwise position unless additional time delay is required due to pulsating flow, turbulence, or splashing. if time delay is used, the red alarm led will first illumi- nate when an alarm condition occurs, the relay activation will occur after the appropriate time delay. time delay occurs while going into alarm. there is no time delay (other than sensor response time) coming out of alarm.
11 54-610 thermatel model td1/td2 flow level switch 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. changing the heater, range, fail-safe, or temperature compensation settings will affect the set point. select the fail-safe mode (hl or ll) before performing the calibration. the fail-safe selection does affect the calibra- tion set point. turning the alarm potentiometer clockwise to go from an alarm condition to the normal (safe) condition. turn the alarm potentiometer counterclockwise to go into alarm. note: the led operation changes with the fail-safe mode selection. the red led is illuminated when an alarm condition exists. high level fail-safe hlfs C the switch goes into alarm under a wet (high level) condition or if the flow rate has increased above the set point. on the td2, the green and yellow leds will be on at low flows or low level indicating a normal condition. the number of green leds illuminated will decrease as the flow rate increases. low level fail-safe llfs C the switch goes into alarm under a dry (low level) condition or if the flow rate has dropped below the set point. on the td2, the green and yellow leds will be on at high flow rates or high level indicating a normal condi- tion. the number of green leds illuminated will decrease as the flow rate decreases. 2.6.1 adjustment procedure for level applications 1. place htr switch in "-" position ( ). 2. set desired fail-safe condition. 3. ensure time delay potentiometer (td2 only) is fully coun- terclockwise (rotate 30 turns or until clicks are heard). 4. immerse in still liquid. wait a minimum of 3 minutes for the sensor to stabilize.

15 54-610 thermatel model td1/td2 flow level switch 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. this value can be recorded and checked in the future to ensure that the set point has not changed since last calibration. note: due to atex requirements, these test points (tp1 and tp2) are not provided on the td2-xd0x-xcx.
16 54-610 thermatel model td1/td2 flow level switch 3.0 reference information 3.1 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. the td1 is the basic version while the td2 offers advanced options including led indication of flow/level, optional remote electronics, ma output representing the sensor signal, time delay, and a voltage signal representing the set point of the unit. sensors are available in 316/316l stainless steel, hastelloy ? c, or monel ? welded construction. the easy to install and adjust units provide reliable, low maintenance performance in the most demanding applications. both switches have continuous diagnostics to detect a failure of the sensor. this is accomplished by continuously monitoring the signal from the sensor which must remain within set levels. in the event the switch detects a fault, the relay will de-energize and the red led will blink. 3.2 theory of operation the thermatel flow/level switch consists of a dual ele- ment sensing assembly mounted integrally to the electron- ics, or the sensor may be remote mounted up to 500 feet (150 meters) from the electronics (td2 only). each element of the sensor is a miniature rtd (resistance temperature detector). one element measures the tem- perature of the process, providing a reference temperature. the second rtd is self-heated to establish a temperature differential above the reference temperature. the cooling effect on the heated rtd, caused by the presence of flow or level, decreases the differential temperature between the two rtds. when the temperature difference reaches the set point, the relay will change state. sensor designs are suitable for operation in temperatures of -100 to +850 f (-73 to +454 c).
17 54-610 thermatel model td1/td2 flow level switch 3.3 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 relay will de-energize. in the td2, the ma output will go to less than 3.6 ma if low level fail-safe is selected or greater than 22 ma if high level fail-safe is detected. if a fault is detected, refer to 3.5 troubleshooting . 3.4 resistance values the following tables provide the expected resistance values for the sensor. refer to the indicated figures for pin locations. refer to 3.6.2 probe replacement for removing bezel and circuit boards. pin expected resistance 1 to 3 90 to 180 ohms (275 ohms with high temperature probe) 2 to 4 90 to 180 ohms (275 ohms with high temperature probe) td1 (see figure 12) pin expected resistance 1 to 3 or 4 90 to 180 ohms (90 to 275 ohms with high temperature probe) 2 to 5 or 6 90 to 180 ohms (90 to 275 ohms with high temperature probe) 1 to 2, 3 to 4, 5 to 6 0 to 12 ohms td2 C integral electronics (see figure 13) td2 C remote electronic enclosure (see figure 14) 123456 shield figure 14 td2 remote probe connections 1 4 1 4 unmarked wires marked wires figure 12 td1 probe connections 1 6 1 6 unmarked wires marked wires figure 13 td2 probe connections
