Complementary information
Y
ou can use the changeover order as an additional check of your control unit. For exam‐
ple, deviations of a vehicle from the route or a plant from the prescribed production
process can be detected.
7.14.2 Several monitoring case tables
Certain variants of the safety laser scanner support multiple simultaneous monitoring
c
ase tables. For example, you can use a monitoring case table to switch between
different monitoring cases with different field sets. At the same time, you can use
another monitoring case table to keep a monitoring case always active with a particular
field set.
Even if you use several monitoring case tables, each shutdown path is assigned to only
one monitoring case table.
If you use several monitoring case tables, one monitoring case must be active in
each monitoring case table at all times. As long as no monitoring case is active in a
monitoring case table after the start, all outputs remain in the OFF state and the device
displays Waiting for inputs. If no monitoring case is active in a monitoring case table
during operation, all outputs switch to the OFF state and the device displays an error.
7.14.3 Settings for monitoring cases
Name
In t
he Name field, you can enter a meaningful name for the monitoring case. If you
create a lot of monitoring cases, you should consider a naming concept that makes
it possible to identify the monitoring cases easily (for example right cornering, left
cornering).
Sleep mode
If y
ou activate this option, the safety laser scanner changes to the sleep mode as soon
as the input conditions for this monitoring case exist.
7.14.4 Input condition
For each monitoring case, you choose the input conditions for which the monitoring
c
ase will be activated. The relevant monitoring case is activated for exactly this combi‐
nation.
Combinations which are invalid or already assigned are marked.
Speed
•
R
ange: The monitoring case is activated if the speed is within the specified range.
You can use static control inputs as additional input conditions.
•
Limit: The monitoring case is activated via the static control inputs. The safety laser
scanner monitors the speed. If the speed is outside the specified range, the safety
laser scanner switches the safety outputs to the OFF state.
In this mode, the safety laser scanner ignores different speeds of the two incre‐
ment
al encoders for 60seconds, even if the difference is greater than the config‐
ured tolerance.
Complementary information
The Generate input conditions function allows you to automatically assign input conditions
to monitoring cases.
