Description
Start level
With the start button the standard requirement is communicated to the operational
control (regulator enable) through the outputs (Q010/Q011) after manual resetting
(Q00A to Q00D closed).
Reset level
The reset does not occur until the reset button has been released with the trailing
edge. This prevents unintentional restart when an error occurs (e.g. short circuit) in
the reset level.
Sensor / actuator level
The reset is realised here in series with the incorporated hardware feedback circuit
(I002). If the guard (I000/I001) and feedback circuit are closed and the reset button
(M000) is activated, the enables (Q00A to Q00D) are activated via a connecting
branch A. As soon as an actuator has finished its mechanical switching procedure,
the start condition no longer exists due to the open feedback circuit (I002). Con-
necting branch A is thus interrupted. The connection is now made via the closed
branch B (as long as the guard is closed). If the guard is opened, the enables
(Q00A to Q00D) are de-activated. This state remains in existence until the guard
and the feedback circuit are closed again. The process described above starts
again from the beginning.
