Control inputs, error relay, sabotage protection
Control inputs
■
Depending
on
control
input
function
and
on
device
configuration,
events
can
be
triggered
by
active
switch
normally
open,
active
switch
normally
closed,
edge
control,
or
permanent
contact.
■
In
principle,
control
inputs
must
be
switched
to
ground.
Use
the
ground
terminals
labelled
on
the
device,
or
the
ground
terminals
of
the
terminal
block
labelled
"
common ground for all inputs of type control
input
"
in
the
table
above.
■
Status
changes
at
the
control
inputs
-
closing
and
opening
of
the
contact
-
must
have
a
duration
of
at
least
500
ms
to
allow
for
positive
detection
by
the
device
and
distinction
from
"swish
contacts".
Error relay
The
device
configuration
allows
designation
of
integrated
relays
as
error
relays
in
order
to
report
certain
operating
states
or
malfunctions
using
dry
contacts.
The
status
of
the
error
relay
then
always
corresponds
to
the
status
of
the
Error
LED
on
the
front
of
SmartDisc
:
■
Error
if
LED
on,
then
error
relay
energised
■
No
error,
if
Error
LED
off,
then
error
relay
de-energised
Examples for
possible errors
reported by
error relay:
■
Recording
underrun
(images
are
overwritten
too
early)
■
Recording
overrun
(insufficient
allocated
storage)
■
Storage
warning
threshold
reached
■
Hard
disk
error
(not
locked,
removed,
or
faulty)
■
Hardware
error
(e.g.
faulty
DSP,
video
decoder,
or
clock
module)
■
Video
signal
failure
(faulty
camera
or
video
cable),
low
contrast
image
(e.g.
caused
by
lens
cover)
■
Remote
connection
(triggered
by
alarm
or
routine
call)
cannot
be
established
For
a
detailed
list
of
error
messages
that
can
trigger
the
error
relay,
refer
to
chapter
"Log
file".
Viewing
the
Log
File
automatically
causes
reset
of
the
error
message;
the
error
relay
is
de-ernergised
and
Error
LED
goes
out.
Refer
to
the
manual
of
the
respective
SmartControl
software
for
more
information
on
log
file
configuration
and
evaluation.
Sabotage protection
The
error
relay
is
pulled
in
idle
-
no
error.
Therefore
the
error
relay
can
be
used
as
sabotage
detector,
as
it
automatically
falls
off
in
the
event
of
power
failure
(e.g.
caused
by
cut
power
lines).
Depending
on
the
error
relay
wiring,
an
interruption
of
the
relay
line
itself
can
be
reported
as
well.
⊥
There
is
a
theoretical
possibility
that
sabotage
protection
will
not
work
if
error
relay
switching
is
not
consistent
with
the
operating
mode.
