7 TKS 03 setting
Systems with personal
protection
When this configuration is selected, the hold-open devices (e.g., door drives)
are re-activated if the light barrier is interrupted during the closing operation.
Both the external and internal signal transducers are energised during this
interruption. In addition, the "light barrier failure" relay is activated. The closing
operation is continued once the light barrier is no longer interrupted.
When the configuration with personal protection is selected,
the hold-open system is re-energised when the light barrier
is interrupted, even if the "fault message with disabled light
barrier" is set.
Systems without
personal protection When this configuration is selected, the hold-open devices (e.g., electromagnetic
retainers) are no longer activated during the closing operation when the light
barrier is interrupted.
No fault message in the
event of disabled light
barrier
When this configuration is selected, a disabled light barrier is not evaluated.
This setting is, e.g., used with light barrier sections that are aligned through the
closing range. In this case, any intentional closing of the zone does not result in
a failure.
Fault message of the dis-
abled light barrier after
2 min
When this configuration is selected, a disabled light barrier is evaluated after
2 minutes. In addition, both the internal and external signal transducers are
energised. The "light barrier failure" relay is activated. If an alarm is received
after the fault message, the fire zone is closed without scanning the light barrier.
This setting complies with VdS and should be used as a rule.
Fault message of the
disabled light barrier
after 10 min If this configuration is selected, a disabled light barrier is evaluated after
10 minutes. In addition, both the internal and external signal transducers are
energised. The "light barrier failure" relay is activated. If an alarm is received
after the fault message, the fire zone is closed without scanning the light barrier.
This setting is, e.g., used with light barrier sections that are interrupted for a pro-
longed time period as determined by the production flow.
The alarm relay drops
out with silent closing When this configuration is selected, the incoming alarm is evaluated as a fire
alarm via connection terminals 19 and 20. The light barrier is scanned, the
"alarm" and "closing initiated" relays are activated, the set time function is
disregarded. In addition, the external visual signal transducer is energised. When
the configuration with
personal protection is selected, the hold-open device is
re-activated if the light barrier is interrupted.
The alarm relay does
not drop out with silent
closing When this configuration is selected, the incoming closing command is evalu-
ated as "silent closing" via connection terminals 19 and 20. The light barrier is
scanned, the "closing initiated" relay is activated, the set time function is disre-
garded. In addition, the external visual signal transducer is energised. When the
configuration with
personal protection is selected, the hold-open device is
re-activated if the light barrier is interrupted.
