Input sequence
from right to left
If the additional function "Discrepancy monitoring" is not used
in a two-channel sensor, this should be especially justified in
the risk analysis.
Door interlocking mechanisms have an infinite discrepancy,
this allows the additional function to be used for error
detection.
With an activated discrepancy monitoring the interlock has
to be opened after an unlocking request.
Kontakteigenschaft (3.
position) = single-channel: The
input with the even number is always evaluated (e.g. sensor
on I02 and I03 the input I02 single-channel is evaluated).
The odd input must remain open.
Sensor type 0 (deactivate): With a HIGH signal to the
sensor inputs of a disabled sensor all safety clearances
are deactivated.
On deactivation of auto-start the function of monitored
start is selected.
Further Parameter
Interlock type
Power to unlock
For spring-locked guard interlocks.
Power to lock
For solenoid-locked guard interlocks.
The interlock type always applies to all connected guard
interlocks.
Analog inputs
Dual Sensor
2-channel analysis of AI0 and AI1 with percentage
tolerance between the two channels.
Single sensor
Single channel analysis of AI0 and AI1.
In addition to the input type, 4 limit values can be set for every input (if
“Dual Sensor“ is selected for both).
Inputs
Standard
(S) No cross-wire detection for input active.
Cross-wire short (C) Cross-circuit detection for this input is active.
Safety mat
(M) Connecting a 4-wire safety mat. Cross-circuit
detection for this input is active.
Times
Each MSP has a safety switch device input filter for bounce on
protective equipment, or detection of failures.
Monitoring time / discrepancy time
Maximum tolerated delay between the channels of a 2-channel input. If
exceeded a warning on the screen is displayed and the indicator light
Y3 flashes. Both channels must be opened to clear before the input can
be activated again. Unless otherwise specified, this time is set to 10s
(guard interlocks set to infinity).
Stable time
During the stable time (default value = 0.1 s) there is a debounce time,
which causes a turn-on delay. The release of the safety function only
takes place when both input contacts are switched stable for the
duration of the stabilizing time.
