3. System Components 3.1 MK292-Compatible Temposonics Position Sensors To interface with the MK292, a start/stop or pulse-width modulated output (see figure 3.1) is required from the Temposonics position sensor. The MK292 will convert these signals into a parallel BCD, Gray Code, or binary output. -

Page 16: System Parameters
< < System parameters are set via the front panel of the MK292 using the programming and BCD switches. • Programming Switch This momentary toggle switch is located at the bottom of the front panel. It has two activation posi- tions: #1 and #2. - Page 17 BCD Switches Programming Switch Figure 5-2 Figure 5-3 Front Panel of MK292 Module BCD Switch • LEDs There are six LEDs, one red and five green, which give visual indication of the operating condition and programming mode of the MK292.

Page 19: Detailed Programming Procedure
7. Detailed Programming Procedure 7.1 (RUN) Programming Mode / Red LED During initial start-up, the red 'RUN' LED will flash. This indicates that the MK292 is in the programming mode and input parameters are required for operation. If the 'RUN' LED is on, but not flashing, this means that parameters have already been set. - Page 20 Switch Setting: PWM Output (circulations) BCD Switch Circulations: 4 Circulations: 16 1) Hold the programming switch in Position #2 until the 'SC' LED is flashing (≈ 3 sec.) ADJUST The MK292 is now ready to accept the next parameter – Scale Factor (SC).
-
Page 21: Sc) Scale Factor
7.3 (SC) Scaling Factor / Green LED Each Temposonics position sensor has its own specific scale factor (gradient) which describes the velocity of the torsional strain pulse through the waveguide medium (refer to 'Principle of Operation'). The gradient is indicated on the sensor's label. Upon initial start-up or when replacing sensors, this value must be set to recalibrate system. -
Page 22: Re) Resolution
The MK292 is now ready to accept the next parameter – Resolution (RE). 7.4 (RE) Resolution / Green LED The resolution that can be achieved by the MK292 is dependent on the input from the Temposonics position sensor. The chart below indicates the range of resolutions depending on sensor type. -

Inches x 25.4 Circulation Count = N 1) Hold the programming switch in Position #2 until the 'ZERO' LED begins to flash (≈ 3 sec.) SETUP The MK292 is now ready to accept the next parameter -- Null Adjust (ZERO). -
Page 24: Zero) Null Adjust
7.6 (ZERO) Null Adjust / Green LED Null adjust allows you to set the mechanical ZERO position anywhere within the active measuring range of the position sensor. Move the sensor magnet to the desired ZERO position and proceed as follows: ZERO 1) Hold the programming switch in Position #2 until the 'ZERO' LED begins to flash (≈... - Page 25 Move the magnet to the desired mechanical start position and calibrate the offset as follows: OFFSET 1) Hold the programming switch in Position #2 until the 'ZERO' LED begins to flash (≈ 3 sec.) ADJUST The displacement output indicated position without the offset calculation 2) Enter the desired offset value using BCD switches S1-S6.

Page 26: Run) Operation Mode
1) Hold the programming switch in Position #1 until the 'RUN' LED begins to flash (≈ 3 sec.) SETUP The Programming Mode is exited and all parameter settings are stored in an EEPROM within the MK292 module. You are now in Operation Mode. -

If the magnet leaves the defined measuring range of the sensor, the system will indi- cate the following outputs: 1. If the magnet leaves the measuring range moving towards the end of the sensor rod, the output voltage will be NEGATIVE. 2. - Page 29 EXAMPLE, BCD Switch Settings SP1 = + 7.565 V SP2 = - 9.480 V S1 = 5 S1 = 0 S2 = 6 S2 = 8 S3 = 5 S3 = 4 S4 = 7 S4 = 9 S5 = 0 S5 = 0 S6 = 0 S6 = 9...
