2.0 PRODUCT DESCRIPTION
The Level Plus M-Series transmitter is multi-functional with two 4-20 mA loops that utilize HighwayAddressable Remote Transducer (HART) communications. It provides up to two analog outputs of level, inter-face, or temperature. An optional electronics module displays simultaneous readouts of level, interface, or tem-perature. The optional electronics module is designed with three push buttons for local setup of all parameters.Outputs can be monitored using 4-20 mA signal output, when you use a RS-232 to HART Hand-Held Converterwith an optional integral display or MTS PC-compatible M-Series Field Setup software.
Level Plus M-Series transmitters can be housed in three types of enclosure configurations: • NEMA 4X electropolished• Stainless steel with I.S. approval• Single cavity or dual-cavity explosionproof enclosure with epoxy-powder coating.
The outer pipe is constructed of a variety of configurations (Contact factory for other materials):• 5/8 in. diameter rigid outer pipe of 316L stainless steel • 5/8 in. diameter rigid outer pipe of polished 316L stainless steel with sanitary process connection
and end-plug.• 7/8 in. diameter flexible pipe of 316L stainless steel
M-Series transmitters utilize a special sensor element which allows easy removal or replacement while the tank orvessel is in service, leaving the tank connection or seal intact. This design allows the sensor element to beinstalled or removed in situations where there is a low overhead clearance.
A temperature sensing function is optional with the M-Series transmitter. The temperature sensing device is aResistive Temperature Device (RTD) mounted inside the transmitter’s outer tube assembly. The RTD is a 1000ohm platinum film device.

2.2 Accuracy
The absolute accuracy of the transmitter is a function of the manufacture of the waveguide. That is, any imper-fections in the waveguide are reflected in the linearity of its output. MTS tolerances reflect a maximum non-lin-earity of 0.035% of full scale. Due to its high degree of repeatability, the differential accuracy is extremely high.
2.3 Theory of operation
The magnetostrictive Level Plus M-Series transmitter will pre-cisely sense the position of an external float by applying an inter-rogation pulse to a waveguide medium. This current pulse causesa magnetic field to instantly surround the waveguide. The mag-net installed within the float also creates a magnetic field. Wherethe magnetic fields from the waveguide and float intersect, arotational force is created (waveguide twist). This, in turn, cre-ates a torsional-sonic pulse that travels along the waveguide asshown in Figure 2-1 “Principal of magnetostriction”.
The head of the sensing element houses the sensing circuit,which detects the torsional-sonic pulse and converts it to an elec-trical pulse. The distance from a reference point to the float isdetermined by measuring the time interval between the initiatingcurrent pulse and the return pulse and precisely knowing thespeed of these pulses. The time interval is converted into a 4-20mA loop signal.
The Level Plus M-Series transmitter offers level, interface, ortemperature outputs. There are two current loops available; anyoutput may be assigned to either of the two loops.

3.0 INSTALLATION AND MOUNTING
The method you use to mount the M-Series transmitter is dependent on the vessel or tank in which it is beingused, and what type of sensor is being mounted. Most applications will require one of two methods; threaded orflange mounting, as shown in Figure 3-1a “Threaded-flange mounting for rigid and flexible pipe” and Figure 3-1b“Welded-flange mounting for rigid and flexible pipe”. (For detailed information about Sanitary application mount-ing, go to 3.2 “Sanitary Sensor Mounting” on page 8.)
3.1 Rigid and flexible transmitter mounting options
3.1a Threaded-flange mountingIn applications with smaller vessels and tanks, the transmitter can be mounted directly to the tank or flange byusing a threaded NPT fitting, assuming there is a proper threaded connection available. If the float will not fitthrough the tank flange, there must also be some means to mount the float on the transmitter from inside the ves-sel; this may require a float access port nearby the entry point of the transmitter (as shown in Figure 3-1a“Threaded-flange mounting for rigid and flexible pipe” on page 6).
Complete the following steps to mount the transmitter using the threaded-flange method:
1. Remove the float(s) retaining hardware, then remove the transmitter.
2. Insert the transmitter tip through the threaded vessel opening or flange.
3. The transmitter tip can now be lowered to the vessel bottom and the connection can be made from the thread-ed NPT fitting to the vessel. In general, there should not be more than 12 inches of the transmitter’s pipeassembly extending above the vessel.
Important:Before you completely insert the transmitter to the bottom of the vessel, you must remount the float(s) through anaccess port and also reattach the float retaining hardware.

3.1b Welded-flange mounting
The M-Series transmitter can also be mounted to a tank flange as shown in Figure 3-1b “Welded-flange mountingfor rigid and flexible pipe”. Complete the following steps to mount the transmitter onto a tank flange:
1. Install the product and interface floats onto the flexible-sensor pipe.
2. Install the bottom-fixing weight, magnet or hook (also referred to as retaining hardware) on to the tip of the trans-mitter.
3. To complete the installation, mount the transmitter, tank flange, flexible-sensor pipe and product/interface floats asan assembled unit in to the tank.
Note:In general, there should not be more than 12 inches of the transmitter’s sensor pipe length extending above the vessel.

3.2 Sanitary transmitter mounting
In sanitary applications, the M-Series transmitter is mounted to the tank using a standard sanitary process connec-tion and sanitary clamp* as shown in Figure 3-2 “M-Series transmitter, tank-mounted sanitary connection”. In mostcases, it is not necessary to remove the sanitary float as the sanitary end-plug fitting is sized to allow installationwith the float in place. Please note that some sanitary end-plug styles have the float(s) permanently mounted.
3.3 Installing a flexible sensor pipe with a bottom-fixing weight or magnet
Complete the following steps to install a flexible sensor pipe with a bottom-fixing weight or magnet:
1. With assistance, feed the flexible sensor pipe through the NPT opening of the tank flange until the flange ispositioned at the rigid section of flexible sensor pipe near the top of the transmitter. Insert the threaded por-tion of the adjustable fitting into the customer flange (apply pipe thread sealant if required). See Figure 3-1a“Threaded-flange mounting for rigid and flexible pipe” on page 6.
2. Slide the product float onto the flexible sensor pipe. See Figure 3-1b “Welded-flange mounting for rigid and flexi-ble pipe” on page 7.
3. Slide the interface float (optional) onto the flexible sensor pipe. Figure 3-1b “Welded-flange mounting for rigidand flexible pipe” on page 7.
4. If you are using a weight or magnet, mount the weight or the magnet to the welded end-plug section of the flexi-ble sensor pipe (this is the bottom rigid section of the flexible sensor pipe) using the supplied nut, spacer andwasher as shown in Figure 3-3 “Retaining hardware” on page 9. Securely tighten mounting nut using 1/2-inchwrench.
Attention:Be careful not to drop the flange on flexible sensor pipe as damage may result.
Important:When assembling and installing the M-Series transmitter, be careful not to allow the flexible hose to kink or becoiled in less than an 16-inch diameter.
To ensure proper and safe assembly and mounting of the transmitter, a minimum of two (2) individuals are required.Gloves are also required.

Insert the flexible sensor pipe (with floats) through the tank riser pipe and lower the transmitterassembly into the tank until it rests on the bottom. DO NOT DROP OR DAMAGE THE PIPE.
6. If you are using a flexible sensor pipe with a bottom-fixing hook, fasten the bottom-fixing hook to the appropri-ate customer-supplied mating hardware at the tank bottom.
7. Secure the flange onto the tank riser pipe.
8. Pull the flexible sensor pipe upward to straighten the pipe until the resistance of the weight or magnet is feltwithout raising the weight or magnet off the floor of the tank. Tighten the adjustable fitting to hold the sensorin place.
9. Terminate the field-wire cables noting proper wire orientation.
3.4 Installing a flexible sensor element
Complete the following steps to replace an transmitter electronics housing and flexible sensor element into an exist-ing pipe assembly:
Attention:• Do not bend flexible sensor element to less than a 16-inch bending diameter or damage may result.• Always use safe handling procedures when handling electronics equipment.• Be sure that the inside of the existing outer pipe is clean and dry, and free of debris before installing the M-Series
transmitter.

4.3 Cable specifications
The following section lists cable parameters and specifications for the M-Series transmitter. The list is not inclu-sive of all cable types and cable manufacturers and should serve only as a guideline when choosing cables. Othercable types can be selected that meet the requirements.
Parameter SpecificationMinimum cable size: 24 AWG or heavier (0.51 mm diameter)
Contact MTS for additional assistance in selecting proper cableCable type: Single pair shielded or multiple pair with overall shieldMaximum cable length: Twisted pair: 10,000 ft. (3,048 m)
Multiple twisted-pair: 5,000 ft. (1,524 m)Maximum cable length formula: Use the following formula to determine the maximum cable length for a
specific application:
L = [(65 x 106) ÷ (R x C)] - [(Cf + 10,000) ÷ C]
Where: L = Length in feet or metersR = Resistance in ohm, current sense resistance plus barrier resistanceC = Cable capacitance in pF/ft, or pF/mCf = Maximum shunt capacitance of smart field devices in pF
Example:Assume a high performing smart transmitter, a control system,and a single pair of shielded wires.R = 250 ohmC = 50 pF/ftCf = 5,000 pF
L = [(65 x 106) ÷ 250 x 50)] - [(5,000 + 10,000) ÷ 50]
L = 4,900 ft (1,494 m)

4.4 Safety guidelines for the M-Series transmitter
Be sure you:
* Follow any applicable local and national electrical codes and observe polarity when making electrical connec-tions.
* Never make electrical connections to the M-Series transmitter when it is powered on.
* Check that no wire strands are loose or sticking out of the terminal block connection on the interconnect boardwhich could short and cause a problem. see Figure 7-2a “Transmitter electronics interconnect board” on page 20/.
* Check that no wire strands, including shield, are in contact with the electronics module or interconnect board.
* Ensure that the electronics module is grounded through interconnect board and electrically isolated from theexplosionproof enclosure.
* Refer to the safe operating power chart in Figure 4-4 “Loop resistance vs power supply” which shows the relation-ship between loop resistance and operating voltage.
4.5 Safety Barriers for IS Installation
Figure 4-5, “Safety barrier types for the M-Series transmitter” illustrates passive/active safety barriers. See page 13 and14 for wiring and entity parameters.

5.0 SYSTEM CHECK
After you complete the M-Series wiring, complete the following steps to perform the system check:1. Apply power to the transmitter.
2. Using a DC volt meter, measure the voltage at loop #1 connections. The voltage must be ≥ 10.5V. If loop #2is being used, measure the voltage at the loop #2 connections, it also must be at ≥ 10.5V. If the voltage levelsare too low, turn off power to the transmitter..
3. Check for shorts, power supply voltage, and excessive loop resistance. Refer to Figure 4-4,”Loop resistance vspower supply” on page 17) which shows the relationship between loop resistance and operating voltage.
5.1 Performing a loop #1 test
To test loop #1, lay the transmitter on a flat surface and move the float along the operational range of the M-Series transmitter. If the transmitter is functioning properly, the output current will change as the float moves.
If the output current is less than 4 mA or greater than 20 mA, this could indicate a problem with the M-Seriestransmitter.
5.2 Performing a loop #2 test (if applicable)
If you are using loop #2, complete the following steps to test the loop (the following test varies depending on theconfiguration):
1. To access loop #2, power on loop #1.
2. If loop #2 is set for level measurement, test the transmitter in the same manner as defined in section 5.1,“Performing a loop #1 test” on page 18.
3. If loop #2 is assigned to measure temperature, first read the output current. Then, if the setpoint values areknown, calculate the temperature using the following formula:
T = [(T20mA - T4mA) ÷ 16] (I - 4) + T4mAWhere: T = TemperatureT20mA = Temperature @ 20 mA setpoint (Factory Setting: 300 °F)
T4mA = Temperature @ 4 mA setpoint (Factory Setting: -30 °F)
I = Output current (in mA)
The M-Series transmitter’s sensing Resistance Temperature Device (RTD) is located at approximately three inchesfrom the transmitter’s tip. Measure the temperature near the tip to see if it is an approximation of the calculatedvalue. If the output current is less than 4 mA or greater than 20 mA, there may be a problem with the sensingRTD (i.e., it may be shorted or open).
6.0 FLOATS
For information about floats, go to www.mtssensors.com and refer to the float specification, MTS part number550537. For float application information, please contact the MTS Level Plus Applications Engineering.

8.0 USING THE KEYPAD DISPLAY TO CALIBRATE THE LEVEL PLUS M-SERIES TRANSMITTERThe M-Series transmitter can be calibrated by using the HART communications protocol or it may be manuallycalibrated using the optional keypad display. This section explains modes of operation and the steps you need toperform to calibrate your transmitter manually using the keypad display.
8.1 Modes of operation
The M-Series transmitter runs in one of the following modes of operation. You can use these modes to calibrateand set up various operating parameters.
Run modeRun mode is the primary mode of operation. This mode will perform measurements, display data, and respondto HART commands. The run mode can be configured for various output options. The minimum configurationwill only perform a single-level measurement. More complex configurations will perform a second float measure-ment (interface), or temperature measurements.
Program modeThe program mode is only applicable to M-Series transmitter with the keypad display option. Enter this mode bypressing any of the three keys, Up keypad, Down keypad, and Enter keypad as shown in Figure 8-2, “M-Series key-pad display”. Menus guide the user through various programming options. When in the program mode, HARTcommunications are not functional. An automatic timeout feature is provided so that the transmitter does notremain inadvertently in program mode.
Display test modeThis mode is invoked through the keypad.
Keypad display usage in program modeThe M-Series transmitter can be configured by pressing three keys, the Up keypad, Down keypad, and Enter key-pad as shown in Figure 8-2, “M-Series keypad display”. This gives the user a means to calibrate and set up variousoperating parameters.

The three keypads are identified with “t” “”, and “<—”. The “s” keypad may be used to indicate Up responses,the “t” symbol indicates Down responses, and “<—” indicates an Enter response. Normally, the M-Series trans-mitter will remain in run mode. When you press any three keys, the transmitter will enter program mode. In pro-gram mode, the electronics module menu displays options that you can scroll through using the Up and Downkeypads. To select an option, press Enter.
Program mode TimerAfter you enter the programming mode, a one-minute timer is started. Each time you press a button, the timer isreset. If you do not press a menu button within one minute, the timer will expire and the transmitter will returnto the run mode (See “run” mode on page 21).
Loop #1 and loop #2 test portsUsing a standard multi-meter set the meter to DC current and attach across the terminals, loop current can beread directly from ports #1 and #2 see Figure 8-2, “M-Series keypad display”. The current read on the meter shouldcorrespond with the data being displayed. These ports allow the loop current to be read directly without havingto interrupt power.
HART portThis port allows for direct connection of the Rosemount-275 or 375 field calibrator or other HART host deviceas long as there is a load on loop 1.
8.2 LCD display and keypad (optional)
A sixteen character, seven-segment LCD display and three button keypad option is available. Level and tempera-ture measurements are displayed when the transmitter is in run mode. When power is applied to the transmitter,a Start message displays. When the transmitter is in run mode, the display is refreshed every three seconds. Thereare three data fields on the display; Level 1, Level 2 and Temperature see Figure 8.2 “M-Series keypad display”. If ameasurement is not available, dashes (- - - - -) will display in the corresponding field.
Note:In program mode, the transmitter will not respond to incoming HART commands. This function will prevent a user ata remote terminal from overwriting a parameter that is being entered at the same time from a local site.

9.0 USING THE HART COMMUNICATION PROTOCOL TO CALIBRATE THE LEVEL PLUS M-SERIES TRANSMITTER
Refer to the documentation that comes with the HART Model 275 and 375 Hand-Held Terminal for specificsensor calibration information. This section describes how the HART protocol is applied to the Level Plus M-Series transmitter only.
Using the HART interface allows for calibration without having to remove the transmitter from the process andposition of the floats. You can perform this function by using HART commands 35 and 65.
Any measured output may be assigned to any variable. Loop #1 is always the primary variable (PV); level one isusually assigned to loop #1. Loop #2 is always the Second Variable (SV); usually represents temperature or level32. The Third Variable (TV) and Fourth Variable (FV) may be assigned to any remaining output such as, level 2,temperature. Analog output codes are 0, 1, and 2 respectively.
Calibration set points for level are given as the absolute displacement (in the appropriate units) from the tip ofthe sensor pipe. For example, if the Zero (LRV) position for level 1 is given as 5 inches, the transmitter will pro-duce 4 mA when the float is 5 inches from the tip of the sensor pipe. If the Span (URV) position for level 1 isgiven as 30 inches, the transmitter will produce 20 mA when the float is 35 inches from the top of the sensorpipe. To calibrate the temperature set points, the Zero (LRV) and Span (URV) points are given in degrees. Fortemperature, the Zero (LRV) value (in degrees) must always be less than the Span (URV) value (in degrees).
9.1 Preparing the transmitter for re-calibration
The M-Series transmitter can be re-calibrated by using the HART model 275 and 375 hand-held terminal.Complete the following procedure to reset the low and high values for loop #1 (only loop #1 can be calibratedwith the HART hand-held terminal using the generic XMTR type driver. To access both loops as well as otherparameters, the MTS device driver must be purchased and installed in to the 275/375 hand-held device. Formore information about the HART device driver, go to HARTcomm.org.
Before you begin, do the following:
1. Connect the transmitter to a clean 24 Vdc power supply. Use a linear supply, switching types does not provideripple-free power. HART cannot tolerate more than a 25 mV voltage ripple.
2. If the unit is installed in a live application, place your automatic controllers in manual mode and be advisedthat the output current will change during calibration.
3. Follow safe working procedures for working on live equipment in a hazardous location before you remove thehousing cover.
4. Connect the HART hand-held terminal to the terminals that are labeled HART located on the front panel dis-play of the Level Plus transmitter.
5. Press the black and white I/O button on the HART terminal. The HART terminal will perform an automaticself test. The Main window displays. If the device is not connected properly, the message “No device found”displays.

2. To write the changed lower value to memory, press the Send key.
3. Two Warning messages will display before the new values take affect; if your new low values are correct, respondto the Warning messages by pressing OK when prompted. This action resets the Low Range Value, or 4 mAposition into the transmitter's memory.
4. Go back to the Range Values window to verify that the new parameters have been accepted into the transmit-ter’s memory.
5. Do one of the following:5.a Exit program mode.
5.b To reset the upper value, continue to 9.3 “Setting the Upper Range Value”.
9.3 Setting the Upper Range Value
Complete the following steps to set the Upper Range Value:
1. Open the Range Values window. To set the 20 mA Upper Range Value, press Key #2. The Process Variable,Upper Range Value (PV URV) window displays.
2. As shown the Lower Value window, the current value displays with a highlighted number below the value dis-played. To change the upper value, key in the new value. You can use whole numbers or whole numbers anddecimals (example, 40 = 40 inches, or 40.5 = 40.50 inches.) Whole numbers will be converted as decimalequivalents automatically by the HART terminal.
3. Key in the new Upper Range Value and press Enter or (F4). The Range Values window displays.
4. Verify that the upper and lower values are correct. If the values are correct, press Send.
5. You will be prompted with two Warning messages, press OK in response to both warnings.
