Digital inputs, digital outputs and relay outputs
Function Descriptions
– Inputs that you assign this function "–" to are being deactivated.
| Emergency open Emergency situation (Fail Safe)
Connect fire brigade 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 operation.
If the signal drops, the pedestrian gate is opened and the passage is
released. The opening direction for emergency open is set via the
"Emergency behaviour" parameter.
This input function is high priority to all other input functions.
Confirm warning
messages
Confirm warnings
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 rebooted.
Open from left Opening pulse for passage from left
If the signal is present for longer than 3 seconds, permanent open is
activated. ä Page 48, chapter 6.2.2, Parameter " Permanent open ".
If several opening pulses are applied, they are counted and stored, and the
hold-open time is added up. If the pedestrian gate is already opened for
passage from right, there is no motor movement. Only the hold-open time is
extended.
Open from right Opening pulse for passage from the right
If the signal is present for longer than 3 seconds, permanent open is
activated. ä Page 48, chapter 6.2.2, Parameter " Permanent open ".
If several opening pulses are applied, they are counted and stored, and the
hold-open time is added up. If the pedestrian gate is already opened for
passage from left, there is no motor movement. Only the hold-open time is
extended.
Close (Inhibit
opening)
Close the pedestrian gate
Use this input to close the pedestrian gate in both passage directions. In the
case of permanent signal, no more opening signals are accepted. Input IN1
"| Emergency open" remains superordinated. This means that the
pedestrian gate can also be opened via input IN1 when the pedestrian gate
is closed.
Illumination off Switching the illumination off and on
As soon as +24 V DC are applied to this input, the floor illumination and the
frame illumination are switched off. As soon as there is no signal at this
input, the illumination is switched on.
