It is the similar problem with glow lamps. Meassure the current of the sensor. If it is higher than the specification of an LOGO! input, then LOGO! read a "1" signal. Check the section "sensor connection" on page 43/44 in the LOGO! manual (V8.3). Here you can find information.

You can't connect a 24 V 3 wire proximity sensor on a 230 VAC base module.
