Cascade input automatic start /
monitored start
Automatic start:
The enabling circuits are switched to the operative
position, as soon as the starting condition on
cascade input 1 has been fulfilled, i.e. as soon as a
static +24 V DC signal is present (e.g. from T3).
Monitored start:
The enabling circuits are switched to the operative
position, as soon as the starting condition on
cascade input 1 has been fulfilled, i.e. as soon as a
static +24 V DC signal is present (e.g. from T3)
and the start button on terminal Y33 has
subsequently been actuated (start with the falling
edge).
-up testing
After a voltage failure, start
-up testing requires that
the sensors at Y12 and Y22 be actuated once by the
system operator.
With automatic starting / without
automatic starting after power
-F Local can be parameterized, so that the
enabling circuits automatically switch to the operative
position after a power failure i.e. without pressing the
start button Y33.
Y12, Y22 or cascade input 1 are parameterized for
"monitored start".
The starting condition on the sensor inputs and on
the cascade input has been fulfilled.
Valid actuation of the start button prior to the
power failure i.e. the enabling circuits were in the
operative position.
DM-F PROFIsafe
The "DM-F PROFIsafe safe tripping" function block consists of 3 sockets:
● Event - PROFIsafe active: Failsafe communication between the F-CPU and the DM-F
PROFIsafe is active.
● Event - Safe tripping: A safety-oriented tripping has been carried out.
● Status - Enabling circuit closed: The enabling circuit is closed.
The following schematic shows the "Safe tripping" function block, DM-F PROFIsafe:
