INTRODUCTION 1.1 Hardware Features The MATHSCON isolating signal converter can be user configured to carry out a wide range of mathematical functions on two isolated input channels. One input is a universal current, voltage, thermocouple, or RTD input and the other can be either voltage or current. Each channel can be multiplied by a factor or linearised and then any of the following functions can be performed on these input channels Addition, Subtraction, Multiplication, Division, Square Root, High Signal Select, Low Signal Select, Absolute Difference. The unit produces an isolated, scalable current or voltage output corresponding to the result of the required function. The unit can be powered by any DC voltage between 16 and 36Vdc or AC voltage between 16 and 32Vac. The instrument is packaged in a compact 17.5mm wide enclosure which can be mounted on a standard TS35 DIN rail. 1.2 Isolation Details The MATHSCON has full 3 port isolation of 1000V between the Input Stage, Output Stage, and Power Supply for functional reasons. 2. UNPACKING The instrument should be carefully inspected for signs of damage that may have occurred in transit. In the unlikely case that damage has been sustained, DO NOT use the instrument, but please retain all packaging for our inspection and contact your supplier immediately. The instrument comes with the following items as standard: 1 MATHSCON-6 Isolating Mathematical Signal Converter 1 MATHSCON-6 User Manual If the instrument has been factory configured the input and output details will be listed on the Serial number label on the side of the unit. If this label is blank then the unit will be set to its default configuration which is 4-20mA on both inputs and 420mA source output, scaled as (A+B)/2. Sensata Technologies Page 3 220808 MATHSCON User Manual If re-configuration is required, please refer to sections 4 and 5 of this manual. 3. CONNECTIONS The MATHSCON is housed in a compact DIN rail mounting enclosure, with 12 terminals, arranged in 4 rows of 3 terminals. Two rows are at the top of the front panel and 2 rows are at the bottom. All the sensor input terminals are on the bottom rows and the power supply and analog outputs are on the top terminals.

CONFIGURING THE MATHSCON ! WARNING ! ! DO NOT OPEN UNIT OR ADJUST SWITCHES WITH POWER SUPPLY, INPUT OR OUTPUT CONNECTED The MATHSCON is an extremely versatile device that can support many different types of input. The unit is configured by turning the power off, selecting the internal switch settings required, and turning the power back on. To open the MATHSCON, 2 catches just below the outer terminal blocks must be pushed in gently, one at a time. The front of the case can then be pulled, and the unit will come out of the box. Press here gently There are 4 switch banks, S1, S2, S3, S5, and one link 201 as shown below: Switch S3 1 12 Switch S2 1 12 Switch S5 1 2 Switch S1 1 12 Link 201 ON = 1 10 11 12 OFF = 0 Switch 10 is OFF Switch 11 is ON Switch 12 is OFF Switch S1 and S2 configures input 1 type, S1 and S5 configures input 2 type, and S3 configures the output type and function. Link 201 should be fitted for a 3-wire potentiometer on input 1. The switch settings are explained in the next few pages.

WARNING ! ! DO NOT OPEN UNIT OR ADJUST SWITCHES WITH POWER SUPPLY, INPUT OR OUTPUT CONNECTED Sensata Technologies Page 12 220808 MATHSCON User Manual 5. CALIBRATING THE MATHSCON When the unit is shipped the MATHSCON will be calibrated for the input and output types and ranges noted on the side label. If this label is blank, then the unit will be calibrated for 4-20mA on input 1 and input 2 and 4-20mA source output. The maths function will be Add 1+2, with scaling equivalent to Input 1 0-50%, Input 2 0-50%, output 0-100%. The MATHSCON is programmed and calibrated using a multimeter and one or preferably two input sources. The led on the front panel is used to indicate if the unit is in run mode (green) or one of the four programming modes (red or amber). 5.1 Run Mode In run mode the LED is green and the MATHSCON is working normally. Modes are selected by pressing either the up or down button on the front panel. After each press, the green LED will flash between 1 and 4 times to indicate which programming mode it will next enter (1 flash is mode 1, 2 flashes mode 2, etc.). To enter a programming mode both buttons must be simultaneously pushed and released. 5.2 Mode 1: Basic Calibration of Output The output must be calibrated to the output range selected with Switch S3. For example, if the output range selected is 4-20 mA : · In run mode choose mode 1 (1 flash of the green led) · Push and release both buttons on the front panel, LED will flash once and then go red · Adjust output to be 20 mA using the up and down buttons on the front panel · Push and release both buttons, LED will go amber · Adjust output to be 4 mA · Push and release both buttons, and the LED will go green, it is in run mode again 5.3 Mode 2: Basic Calibration of Inputs 1 and 2 The inputs must be calibrated to the two input ranges selected with switches S1, S2, and S5. Four values are learned in this order: Input 1 Span then Zero, Input 2 Span then Zero. For example, if Input 1 is 0-10V and Input 2 is 4-20mA. · In run mode choose mode 2 (2 flashes of the green LED) · Push and release both buttons, LED will flash twice and then go red · Inject 10V into input 1. The output will take a few seconds to stabilize as the input value is averaged to ensure an accurate reading is taken. Sensata Technologies Page 13 220808 MATHSCON User Manual · Wait until the output is stable then push the up button to confirm the value. · Push and release both buttons, the LED will go amber · Inject 0V into input 1 · Wait until the output is stable then push the up button to confirm the value · Push and release both buttons, the LED will go red · Inject 20mA into input 2 · Wait until the output is stable then push the up button to confirm the value · Push and release both buttons, the LED will go amber · Inject 4mA into input 2 · Wait until the output is stable then push the up button to confirm the value · Push and release both buttons, the LED will go green, it is in run mode again Note: if the up button is not pressed and released, the input value won't be learned. 5.4 Mode 3: Advanced Scaling If the input ranges are weighted differently (e.g., Input 1: 5-80%, Input 2: 18-65%), scaling must be applied to each input before the maths operation is applied. Four scaling values must be programmed to achieve this (e.g., a value represents 5, another 80, then 18 and 65). The scaling values are programmed into the MATHSCON by adjusting the output to proportionately represent the weighting of ScalingVal = x *(OutputSpan - OutputZero) + OutputZero Biggest Where x is the %value to be represented (eg 5,80,18 or 65 in example), Biggest is the biggest of the 4 %values (80), OutputZero and OutputSpan are the values calibrated in Mode 1, for example 4 - 20mA the two inputs. This equation allows us to calculate four scaling values: Input 1: 5-80% is 5 mA to 20 mA Input 2: 18-65% is 7.6 mA to 17 mA The four scaling values are learned in this order: Input 1 Span (20 mA) then Zero (5 mA), Input 2 Span (17 mA) then Zero (7.6 mA). · In run mode choose mode 3 (3 flashes of the green led) · Push and release both buttons, the LED will flash 3 times then go red · Adjust output to be 20 mA using the up and down buttons on the front panel · Push and release both buttons, the LED will go amber · Adjust output to be 5 mA · Push and release both buttons, the LED will go red · Adjust output to be 17 mA · Push and release both buttons, the LED will go amber Sensata Technologies Page 14 220808 MATHSCON User Manual · Adjust output to be 7.6 mA · Push and release both buttons, led will go green, it is in run mode again 5.5 Mode 4: Calibrate MATHSCON Output The MATHSCON must be taught what the output should be for two different sets of input values, ideally at either end of the output scale. Best results are obtained with two input sources, but it is usually possible to do this calibration with only one. If one of the inputs is not connected, the value of that input will default to the %value of its zero point, so if the input is scaled from 0% and multiplication is carried out, the result will always be zero, regardless of the value on the other input. Similarly, for a "lowest" maths operation, two input sources are required to set up an output value that is not zero. The two points are learned in this order: Output Span point then Zero point. E.g.: Input 1 is 0-10V and Input 2 is 4-20 mA Input 1 is scaled 5-80% and Input 2 is scaled 18-65% Output is 4-20mA, maths operation is Add, Output is scaled 23% to 145% If 2 input sources are available : · In run mode choose mode 4 (4 flashes of the green led) · Push and release both buttons, the LED will flash 4 times then go red · Inject 10V into input 1, 20 mA into input 2 · Adjust output to be 20 mA using the up and down buttons on the front panel · Push and release both buttons, the LED will go amber · Inject 0V into input 1 and 4 mA into input 2 · Adjust output to be 4 mA · Push and release both buttons, the LED will go green, it is in run mode again If 1 input source is available (say 0-10V), calculate what the output should be with one input at full scale, the other at zero Output span point = ((80+18)-23)/(145-23)*(20-16)+4=13.836 mA · In run mode choose mode 4 (4 flashes of the green led) · Push and release both buttons, the LED will flash 4 times and then go red · Inject 10V into input 1, leave input 2 disconnected · Adjust output to be 13.836 mA using the up and down buttons on the front panel · Push and release both buttons, the LED will go amber · Inject 0V into input 1 leave input 2 disconnected · Adjust output to be 4 mA · Push and release both buttons, and the LED will go green, it is in run mode again Sensata Technologies Page 15 220808 MATHSCON User Manual If an input is not connected, the input value that the output uses will correspond to the value learned in Mode 2 when the zero-scale input was learned. In other words, the input is clipped at the bottom end. Inputs are not clipped at the top end, however. 5.6 Reset the Calibration Values To reset the Mode 4 output calibration, change one of switches 11 or 12 and power on, off then change the switch back again. To reset the Mode 3 maths scaling, change one of switches 8, 9, or 10 and power on, off then change the switch back again. Sensata Technologies Page 16 220808 MATHSCON User Manual 6. INSTALLATION The MATHSCON's input and output circuits are classed as Separated Extra Low Voltage (SELV). This means that they must not be externally connected to voltages exceeding 30V ac or 60V dc, nor do they generate voltages above these limits internally. Where a higher voltage input is required a specially designed DIVIDER unit can be used to condition the input signal before connection to the process input terminals. The MATHSCON unit clips directly onto the `Top Hat' (TS35) symmetrical DIN rail. Ideally, mounting orientation should be vertical. Good airflow around the unit will maximize the reliability of the instrument. The use of ferrules is recommended for wiring terminations. Do not exceed the terminal torque rating of 0.4 Nm use an appropriate screwdriver. The unit can be removed from the DIN rail by sliding a small screwdriver into the slot at the rear of the enclosure on the lower face and gently levering the metal clip, whilst lifting the unit from the rail.
