10.7.4 Mode 4: Two-Pulse control (bistable)
Typical application This mode is suitable for barriers on factory premises, etc. that are
often frequented by vehicles. The barrier must be operated by a
person.
Function The barrier is opened and closed completely via two separate
command units (signal). One pulse on the respective input is
sufficient for opening or closing. The pulse must be present
between 100 and 300 ms.
The input function "Open high priority" is superordinated to the
input function "Close". This means that while a closing signal is
applied, the barrier can be opened by the signal “Open high
priority”. When the opening signal is removed, the barrier closes
again at once after opening completely.
