A coil is automatically switched off if the power fails and if
easy is in STOP mode. Exception: Retentive coils retain signal
1 (see a Section “Retention”, Page 283).
“Set”
S and “Reset” R coil function
The “Set”
S and “Reset” R coil functions are normally used
in pairs.
The relay picks up when the coil is set (A) and remains in this
state until it is reset (B) by the coil function.
The supply voltage is switched off (C), the coil does not have
a retentive effect.
Figure 62: Signal diagram of “Set” and “reset”
If both coils are triggered at the same time, priority is given
to the coil in the circuit diagram with the higher circuit
connection number. This is shown in the above signal
diagram in section B.
Figure 63: Simultaneous triggering of Q01
In the example above, the reset coil has priority with
simultaneous triggering of the set and reset coils.
