Parallel circuit operating like a series connection of break
contacts
A series circuit with more than three contacts (break contacts)
can be implemented with a parallel connection of make
contacts on a negated coil.
In the EZ circuit diagram you can switch as many rungs in
parallel as you have rungs available.
Table 20: Parallel connection of make contacts on a negated coil
Two-way circuit
A two-way circuit is made in EZ using two series connections
that are combined to form a parallel circuit (XOR).
An XOR circuit stands for an “Exclusive Or” circuit. The coil is
only energized if one contact is activated.
