Digital inputs, digital outputs and relay outputs
Clamp Function
– Inputs that you assign this function "–" to are being disabled.
| Emergency open Emergency situation (Fail Safe)
Connect fire service switches, emergency opening contacts, etc. to this
input. This input has the highest priority. As soon as +24 V DC are applied to
this input, the turnstile is in operation.
For turnstiles with the "Drop arm" option, the holding magnet for the drop
arm is released immediately in the event of a signal drop. The motor starts
up briefly so that the drop arm can be released.
For turnstiles without the "Drop arm" option, the passage is immediately
enabled in both directions in the event of a signal drop.
This input function is high priority to all other input functions.
Confirm warnings Confirm warning messages
A pulse at this input confirms the "Warning" output function. The output is
reactivated the next time a warning occurs.
The number of the warning message remains stored in the event list until
the control unit is restarted.
Open from left Opening pulse for passage from the left
If the signal is present for longer than 3 seconds, Permanent open is
activated. äPage 30, chapter 4.2.2, parameter "Permanent open".
Open from right Opening pulse for passage from the right
If the signal is present for longer than 3 seconds, Permanent open is
activated. äPage 30, chapter 4.2.2, parameter "Permanent open".
Inhibit opening Locking the turnstile
Use this input to lock the turnstile in both passage directions. No opening
signals are accepted anymore. Input IN1 "| Emergency open" remains
superordinated. This means that the turnstile can also be opened via input
IN1 when the turnstile is locked.
| Over-climb
detection
Sensor connection for over-climb detection (Fail Safe)
This input is used to connect a sensor such as a light barrier or a light switch
for detecting attempted climbing. As soon as 0 V is applied to this input and
there is no release for a passage, the function is activated and the "Climbing/
Crawling" output function is set.
| Under-crawl
detection
Sensor connection for under-crawl detection (Fail Safe)
This input is used to connect a sensor such as a light barrier or a light switch
for detecting attempted crawling. As soon as 0 V is applied to this input and
there is no release for a passage, the function is activated and the "Climbing/
Crawling" output function is set.
Random function Activate random function, confirm hits
As soon as +24 V DC are applied to this input, the random function is
activated. If a hit is generated, the hit can be confirmed with a 0 V pulse via
this input. äPage 35, chapter 4.2.7, "Random function" menu.
