5.2.4.7.9 Gap Suppression
For transport items with gaps, brief interruptions in the muting signal are to be expected. The “Gap Suppres-
sion” function ensures that a brief interruption in the detection does not result in the muting being terminated.
If the function is activated, interruptions of up to 250 ms are accepted in the signal from a MS.
DANGER!
• The “gap suppression” delays the termination of the muting by 250 ms.
• The user must ensure that, despite the set off-delay, no person can enter the danger zone.
5.2.4.7.10 Override
In some cases, a valid muting sequence can be interrupted due to the conveyor belt stopping, for example.
In this case, the object stops and prevents a valid muting sequence from being carried out. The Override
function enables the object to be transported out of the muting area despite the safety field being penetrated.
Usage condition
Condition Comment
1. Condition for
override Override function is parametrized.
A penetration of the safety field is
detected and at least
1 MS is active. With 2-sensor linear muting, the status
of the MS is not taken into account.
2. Override is request-
ed Valid signal sequence on the “Over-
ride” input See Figure 17
3. Active override “Override” input is active and at least
1 MS is active and penetration of the
safety field is detected. –
4. Override ended • “Override” input inactive or
• Safety field free and no MS active or
• Maximum override duration exceed-
ed
Depending on which status is reached
first. Maximum override duration: 150
s
Figure 17 shows a sample signal sequence during override.
