1)
The input delay applies to ”0” after ”1” and to ”1” after ”0”
2)
Short circuit of the sensor supply
3)
Configurable only with IM151-1 HIGH FEATURE and IM151-7 CPU interface module

If the wire-break test is enabled, all free inputs must be stabilized so they do not trigger a module wire
break. This requires a resistor between terminal 24/48 V
(3, A4, 7, A8) and the free input. The resistor must supply an input current of at least 0.5 mA (see
”Sensor circuit” in the technical specifications table). This ensures that sufficient current will flow to
prevent wire-break detection.
When switched off the sensor must supply at least 0.5 mA (otherwise a wire-break will be detected
when switched off). Alternatively a resistor can be installed parallel to the sensor terminals (current
must be at least 0.5 mA).
