    Default Cr108x CLAMP 15 wiring

    All the IFM literature we've found labels pin 1, connector 1 as CLAMP 30 (permanent battery) & pin 5, connector 1 as CLAMP 15 (switched voltage). Our assumption was that you could leave pin 1, connector 1 permanently wired to the battery & control switching the display ON/OFF via pin 5, connector 1. That doesn't appear to work. Pin 5, connector 1 needs to have voltage for the display to power ON, but removing it isn't powering it OFF.

    Are we missing something? This isn't a big deal since we usually just switch both pins together. But we decided to experiment with the "recommended" wiring per the installation manual. Thanks.

    You have to program the display to shutoff with the clamp pin.


    This will shutdown the display when the power is removed from pin 5
