    EnglishBTMA1___ / BTME1___MultiChannel Analog Output Processor

    Example:

    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.

    on off off off

    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
