Contactor function with negated result (inverse contactor
function)
Å
The output signal is simply an inversion of the input signal; the
relay operates like a contactor with contacts that have been
negated. If the coil is triggered with the 1 state, the coil
switches its make contacts to the 0 state.

Representation in EZ
• Output relays Q:
ÅQ1 to ÅQ8 (depending on type)
•Markers M, N:
ÅM1 to ÅM16, ÅN1 to ÅN16
• Function relays (Text) D: ÅD1 to ÅD16
• Output relays S: ÅS1 to ÅS8
• Jumps: Å:1 to Å:8
Falling edge evaluation (cycle pulse) è
This function is used if the coil is only meant to switch on a
falling edge. With a change in the coil state from 1 to 0, the coil
switches its make contacts to the 1 state for one cycle.
