Description of menus and parameters
6.2.7 Random check function
The MGCplus control unit is equipped with the "Random check function" op-
tion. This function allows random bag and identity control of persons.
If a hit was generated by the random check function and the next validation is
blocked by the random check function, the following symbol appears on the
display of the control unit: « ».
For the random check function you can choose between "Counting" or "Ran-
dom" modes. You activate the random check function via a permanent signal
(+24 V DC) at the "Random check function" input. If the random check function
has generated a hit, the pedestrian gate is not opened despite a valid opening
pulse. A signal is emitted at the output with the "Random hit" function. You
can connect a signal lamp or a siren to this output.
The passage remains blocked until the random hit / validation is confirmed
with a 0 V pulse at the "Random check function" input.

Parameter Description
Mode Set the function of the random check function.
Options
› Inactive: The random check function is not in operation.
› Counting: If the number of passages since activation has reached the set
value for the "Hit range" parameter, a hit is reported and the passage is
blocked. For example, if you set the value "100" for the "Hit range" pa-
rameter, a hit is generated every 100
th
passage.
The hit is confirmed via the "Random check function" input function. Af-
ter acknowledgement, the random check function counter restarts.
› Random: You can set the random probability using the "Hit range" and
"Count of hits" parameters. By activating the random check function, the
set "Count of hits" is randomly generated, which must lie within the set
"Hit range". For example, if you set the value "100" for the "Hit range" pa-
rameter and "10" for the "Count of hits" parameter, hits are generated
randomly for 10 people out of 100.
