4-42 Drawing a Circuit Diagram with Pico
Make sure that both coils are wired up in the correct order in the Pico circuit
diagram: first wire the “S” coil and then the “R” coil. This means that the machine
will be switched off when I2 is actuated, even if I1 is switched on.
Flip-Flop Relay
A flip-flop relay is often used for controlling lighting
such as for staircase lighting. Press the push button
wired to I1 once and the lights turn on. Press the push
button again and the lights turn off.

On-Delayed Timing Relay
The on-delay can be used to gate short pulses or to
initiate another movement after a time delay when a
machine is started.
The parameter settings for T1 are:
• Timing function on-delayed: “X”
• Time value and range: 10 seconds
If I1 is switched on, the trigger coil (TRG) of T1 is
energized. After 10 seconds, T1 turns on the output
relay Q1. If I1 is switched off, relay coils T1 and Q1
drop out and the timer is reset.
