Working with contacts and
relays
In EZD circuit diagrams, the switches, buttons and relays of
conventional circuit diagrams are connected up using input
contacts and relay coils.
EZD circuit diagram:
First specify which input and output terminals you wish to use
in your circuit.
The signal states on the input terminals are detected in the
circuit diagram with the input contacts I, R* or RN. The outputs
are switched in the circuit diagram with the output relays Q, S
or SN.
Entering and changing contacts and relay function coils
Contacts
An input contact is selected in the EZD via the contact name
and contact number.
Example: input contact
