Description
During the delay time, sensor signal changes
are not evaluated.
• Delay time 50ms: Changes in the switching
position of strongly bouncing contacts are
hidden (e.g. position switch on heavy
protective doors).
• Delay time 10ms: The shorter delay time
allows for a quicker tripping of bounce-free
sensors (e.g. light arrays).
• Automatic start: The enabling circuits are
switched to the operative position, as soon
as the starting condition on sensor inputs
Y12, Y22, Y34 and 1 have been fulfilled. The
start button connection terminal Y33 is not
queried.
• Monitored start: The enabling circuits are
switched to the operative position, as soon
as the starting condition on sensor inputs
Y12, Y22, Y34 and 1 have been fulfilled and
the start button on terminal Y33 has
subsequently been actuated (start with the
falling edge).
• 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).
After a voltage failure, start-up testing requires
that the sensors at Y12 and Y22 are actuated
once by the system operator.
The DM-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.
Prerequisites:
• 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.
