  • Page 3: Summary

    (three types suited for use with Trans-O-Prox III: wms-251/RT, wms-501/RT and wms-800/RT , a mixed operation of both sensor types is allowed). Therefore four groups of terminal blocks for connecting the sensors can be found on Trans-O-Prox III ( sensor power supply + , GND, sender, echo).

  • Page 4: Transponder Mode

    RS232 with each measurement cycle to a host computer. The echo mode is selected, when Trans-O-Prox III has been activated and when there is a GND signal on MODE or when it is left open (unconnected). The echo mode can also be selected by a command via the serial interface.

  • Page 5: Programming Mode

    2.3.1 Manual programming During normal operation (Trans-O-Prox III activated) the switching distances (trip points) of the currently active mode (echo or transponder) can be adjusted by the buttons on the front panel. To enter manual programming press the ENTER button for 3 sec, until both yellow LEDs A1 and A2 start to blink.

  • Page 6: Command Set

    Manual Trans-O-Prox III page 28 of 42 must be terminated by a <cr> (carriage return, ASCII code 13 If the command is directly followed by a <cr>, the current parameters associated with this command will be output. Entering a parameter value after a command overwrites the pre- viously valid parameters, if parameters are entered in the correct format.

  • Page 7: Sp - Choice Of Used Language

    By the SA command the permanent inner switching distances (near trip points) are selected for the echo mode. SA<cr> subsequently outputs all trip points of sensor channels 1 to 4 (channel 4 is irrelevant for Trans-O-Prox III however, see chap. 3 ). Command format: SAx:y , x = channel no.

  • Page 8: Ta - Temporary Inner Switching Distance For Echo Mode

    Manual Trans-O-Prox III page 30 of 42 switching distance too low , decrease near switching distance first´ appears. The SB command stores the distances values within a non volatile memory (EEPROM), so that switching distances are memorized, when switching off the power supply.

  • Page 9: Hb - Hysteresis Of Switching Output A2 For Echo Mode

    Manual Trans-O-Prox III page 31 of 42 2.3.2.8 HB - hysteresis of switching output A2 for echo mode A switching hysteresis of output A2 for the far trip distance may be specified by the HB command, valid for the echo mode. Allowed values are 0 to 15 (equivalent 0 to 30 cm). If the approach of an object has led to a switching, the output will not be reset until the object distance has gone above TB + HB again.

    Manual Trans-O-Prox III page 32 of 42 ,y = distance value 2.3.2.12 YB - temporary outer switching distance for transponder mode If during normal operation the outer switching distance for transponder mode is altered very frequently, one should better use the YB command instead of the XB command. YB changes the outer switching distance only temporarily without storing it in the EEPROM.

    , x = 1 variable transmitted pulse length depending on measured distance 2.3.2.17 MD - Selection of pure echo mode By the MD command can be determined, whether the Trans-O-Prox III should operate in a pure echo mode on all four channels, or if it should also have the transponder function with channel 4 being the active reflector.

    Manual Trans-O-Prox III page 34 of 42 2.3.2.20 PH - peakhold of switching outputs If an object approach has led to a switching of output A1 or A2, the on-state of the switch- ing output is maintained for a specified number of measurement cycles given by PH, after the switching criteria has vanished, i.e.

  • Page 13: Dt - Software Validation Date

    The DT command outputs the software validation date. 2.3.2.26 NR - serial number of the Trans-O-Prox III Every Trans-O-Prox III is identified by a serial number, when can be called by the NR com- mand. 2.3.2.27 RS - system reset (cold boot) A software cold boot is performed as if there were a reset impulse, when switching on the power supply.

    Manual Trans-O-Prox III page 36 of 42 2.3.2.30 IT - logical signal state, when signal input disabled If a signal input has been disabled by the IS command, the logical state must be specified by the IT command. After a reset the value for IT is undefined.

To enter programming mode when it is unknown, which baud rate has been selected previously by BD, fixed baud rates can be forced by keeping the UP or DOWN button pressed, while switching on the power supply.

    XOFF (ASCII code 19dec). 3. Further informations Using the MD command Trans-O-Prox III can be adjusted in a way, that it operates in a pure echo mode. There is no transponder mode in this case; the function as active reflector on channel no.4 is void.
