Setpoint Programming with the Infrared Setpoint Programmer - G-Series Analog Output sensors only

Using the MTS IR Setpoint Programmer it is possible to adjust the G-Series

Analog sensor output at the ends of stroke for the Null (Setpoint 1) and Span

(Setpoint 2).

Required Equipment:

• G-Series model sensor

• Mating cable for sensor (if necessary)

• IR Setpoint Programmer (part no. 380078)

• Sensor power supply (+20.4 to +28.8 Vdc for input voltage option 1, and

+9 to +23 Vdc for option 2)

• Voltmeter or Ammeter (depending on output)

Setpoint Programming

Caution:

Prior to initiating G-Series programming, it is critical that the user ensures

that taking the sensor out of normal operating mode or

modifying the sensor's operating parameters will not cause harm to the

process utilizing the G-Series sensor feedback, nor to any persons associ-

ated.

For G-Series Analog sensors, the Null (Setpoint 1) value applies to the output

at the beginning of the measurement stroke nearest the sensor's electronics

housing. The Span (Setpoint 2) value applies to the output at the opposite

end, nearest the sensor's dead zone. For the G-Series model configuration

analog sensor output codes (e.g. V0 = 0 to 10 Vdc), the first value always

refers to the Null (Setpoint 1) output, (See Note 1).

1. Hold the IR Setpoint Programmer with the front facing the sensor LEDs,

no more than 4 inches (100 mm) away without obstruction. Press and

hold the programmer's POWER button and then apply power to the

sensor. Once the sensor receives the IR programming command, it will

respond with a continuously flashing red LED. If the sensor does not

enter IR programming mode, power down the sensor and repeat this step

again.

2. Programming inputs are made by pressing AND releasing the

programmer's buttons while the device is directed at the sensor LEDs.

When a valid input from the programmer is received and processed by

the sensor, it will display two green LED flashes (see Note 2). To adjust

the sensor setpoints follows the steps below.

3. Move the position magnet to the desired Null (setpoint 1) position. Then

select the + or - button below the "NULL (SP1)" label to increase or

decrease the output as shown on your meter. Select the COARSE or

FINE (1 or 2) buttons for larger or smaller adjustments (See Note 1).

4. Next move the position magnet to the Span (setpoint 2) position and

select the + or - button below the "SPAN (SP2)" label to increase or

decrease the output.

5. Return the position magnet to the null and span locations and confirm

that the outputs are as expected. Use the FINE adjustment feature if

necessary.

6. The new setpoint values will remain active until the sensor is powered

down. To save the adjustments to sensor memory, click the SAVE

(Enter) button. Otherwise, the sensor will revert to the last saved values

prior to power down. During programming to recall the last saved

values, click the RECALL (5) button.

N N o o t t e e : : A second button labelled "Recall" resides at the lower left side of

the programmer. It has no effect for setpoint programming.

7. Power to the sensor must be cycled to exit the IR setpoint programming

mode.

Hardware setup notes: :

1. Make sure sensor is NOT connected to the control or sensor interface.

2. Do not apply power to the sensor yet. However, make sure that the

appropriate power source and ground connections are correct as

indicated in Table 1 on page 2 .

3. Connect your voltmeter or ammeter to the sensor output and output

return signals as shown in Table 1 on page 2.

Notes:

1. G-Series Analog sensor outputs are adjustable over the entire sensor span.

The minimum adjustment increment is 0.015 inch (0.35 mm) and the

minimum spacing between null and span is 1 inch (25 mm). Do NOT attempt

to reverse the output polarity of the G-Series sensor by adjusting the setpoint

values. (To change the output polarity use the PC Setup Software to program

the sensor for a different output range.)

2. The sensor will continue to receive and process valid inputs when the

programmer's buttons are pressed and held down even after displaying the

two green LED flashes. However, when processing this streaming input

signal from the programmer, the sensor will not provide additional feedback,

(i.e. no additional two green LED flashes). Also, there will be no voltage or

current changes on the output until the programmer's button is released.
