MGC Control Unit
Digital inputs, digital outputs and relay outputs
Clamp Funcon
–Inputs that you assign this funcon "–" to are being deacvated.
| Emergency open Emergency situaon (Fail Safe)
Connect re 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 pedestrian gate is in operaon.
If there is no signal at this entry, the passage is cleared in both direcons.
This input funcon is high priority to all other input funcons.
Conrm warnings Conrm warnings
A pulse at this input conrms the "Warning" output funcon. The output is
reacvated the next me a warning occurs.
The number of the warning message remains stored in the event list unl
the control unit is restarted.
Open entry Opening pulse for the passage from the zone not controlled (ZNC) to the
zone controlled (ZC)
If the signal is present for longer than 3 seconds, Permanent open is
acvated. äPage 28, Chapter 4.2.6, parameter "Permanent open".
Open exit Opening pulse for the passage from the zone controlled (ZC) to the zone not
controlled (ZNC)
If the signal is present for longer than 3 seconds, Permanent open is
acvated. äPage 28, Chapter 4.2.6, parameter "Permanent open".
Inhibit opening Lock pedestrian gate
Use this input to lock the pedestrian gate in both passage direcons. No
opening signals are accepted anymore. Input IN1 "| Emergency open"
remains superordinated. This means that the pedestrian gate can also be
opened via input IN1 when the pedestrian gate is locked.
Random check funcon Acvate random funcon, conrm hits
As soon as +24 V DC are applied to this input, the random funcon is
acvated. If a hit is generated, the hit can be conrmed with a 0 V pulse via
this input.
For this entry to be eecve, you must select the opon "Counng" or
"Random" for the parameter "Mode" in the "Random check funcon" menu.

Sensor B1 (internal use) Connecon proximity sensor B1
Sensor B1 is connected to this entry by default. The inducve proximity
sensor is used to detect the end posions.
Sensor B2 (internal use) Connecon proximity sensor B2
Sensor B2 is connected to this entry by default. The inducve proximity
sensor is used to detect the end posions.
