    Application Examples

    Functional Description

    The BTM-A1__ / BTM-E1___is aDIN rail-mount, analog outputmodule which can provide multipleoutputs when used in conjunctionwith Balluff Micropulse digitalSTART/STOP transducers. TheBTM module can be configured toprovide position feedback, velocityfeedback or both position ANDvelocity feedback. In addition, theBTM module can be used withmultiple magnets on a singletransducer. The BTM module iscompletely user-programmable tomeet a wide variety of applicationrequirements.


    Balluff positioning systems areused in many areas includinghydraulic cylinders, presses, punchpresses, extruders, rolling mills,injection molding, blowmolding,woodworking and packagingmachinery, textile machinery, aswell as elevators, liquid levelmonitoring systems, and handlingequipment.

    The BTM module is factory-configured to provide 0V at thebeginning of the active stroke, and10V at the end of the active stroke.In some applications, it may benecessary to configure the outputfor values other than 0V and 10V10V(e.g., 1V and 9.5V)

    ModesInstallation and Setup

    The BTM-A1/E1 Module isdesigned to be mounted on astandard DIN rail. Shielded cableshould be used between the BalluffBTL.-P1... transducer and the BTMmodule. Consult the diagram onpage 5 for wiring information.

    Basic Programming

    BTM-A1/E1 module has twobasic modes of operation:

    - Normal Mode- Program Mode

    Normal ModeUpon start-up, the BTM-A1/E1always enters Normal Mode.While in Normal Mode, all front-panel LEDs off indicates thatthere are no errors present. Thefront-panel push buttons areused to enter Program mode.

    Program ModeIn Program Mode, it is possibleto:

    1. Scale the position signal(s).2. Set the output direction

    (rising or falling)

    Programming Notes

    - If the magnet travels more than4mm beyond the programmedsetpoint, the corresponding LEDwill blink to indicate an error.

    - Any error indication can becleared by simply correcting thecondition which is causing theerror.

    The Online adjustment mode can beused to manually adjust the output ofthe BTM module to any range.

    - Manually position the magnet atthe desired 0 V (BTM-A1) or 4mA (BTM-E1) point.

    - Press and release the PRG-button.

    - Position the magnet at thedesired 10 V (BTM-A1) or 20 mA(BTM-E1) point.

    - Press and release the PRG+button.

    The position signal should now bescaled to the proper length. Press theSEL+ or SEL- button to exit ProgramMode.

    Important - Before the onlineadjustment procedure is per-formed the output range andslope (rising or falling) must beset using the standard positionprogramming procedure.

    Position Programming (scaling) -single magnet mode

    The BTM module comes factoryconfigured to produce the followingposition output signals on channel1:

    BTM-A1 - 0 to 10 VdcBTM-E1 - 4 to 20 mA

    If an output range of other than 0 to10 V (e.g., -10 to +10 V or -5 to +5V) or 4 to 20 mA (e.g., 0 to 20 mA) isdesired, refer to the section entitledAdvanced Programming (page 8).

    Use the following procedure toscale the output range. Theminimum allowable range is 1".While perfor
