5.5 Operation contingencies and response
The turnstile is capable of providing information on the following operation contingencies:
1. Unauthorized
access.
2. Passage delay for more than 10 sec.
3. Barrier arms rotation sensor failure.
4. Intrusion detector activation (Sect. 5.4.2).
5. Power failure (decrease below acceptable level)
In the cases 1-4, a special
Alarm
signal is generated by closing the
A1
and
A2 X1
connector
contacts. The "Alarm" relay output signals parameters are indicated in Sect. 5.4.1.
When eliminating the cause of the
Alarm
signal, the "Alarm" relay contacts open and the signal is
removed.
An alarm lamp (buzzer) in the driver's cab can be connected to the output of the “Alarm” relay,
alerting the turnstile emergency operation.
During operation, the microprocessor monitors the voltage supplied to the turnstile, and when the
voltage is reduced (less than 21.8V), the "Battery" relay contacts (
LV1
and
LV2
of
X6
connector
block on the interface board (10)) will be closed to each other, indicating a low supply voltage (low
battery). With a subsequent increase in voltage to 23.6V, the "Battery" relay contacts
LV1
and
LV2
will open, thus indicating a nominal supply voltage (battery charge). The parameters of the
“Battery” relay output signals are indicated in Sect. 5.4.1.
In case of a voltage drop below the threshold value for switching off the electronics (17V), the
turnstile electronics will automatically disconnect from the power source. When voltage is restored
above the threshold for switching the electronics on (18V), the turnstile electronics will
automatically turn on.
6 MARKING AND PACKAGING
The turnstile has the marking on the inner surface of the side wall of the turnstile base. The label
contains manufacturer’s trademark and contact details, year and month of production, operating
voltage and power consumption of the turnstile.
To get access to the label it is necessary to detach the turnstile housing (1) from the turnstile base
in the following way:
1. Unscrew the four fixing screws of the housing (7) using the SW3 Allen key. The screws are
located on the lower surface of the turnstile base, the hub side.
2. Lift the turnstile housing by the lateral faces to half the height of the turnstile base.
3. Separate the indication cable (8) from LED indication unit (2).
4. Detach the housing carefully and put it on a plain and steady surface.
The housing is mounted on the turnstile base in the reverse order. When lowering the housing,
make sure that the indicator cable (8) folds forward and is not pinched by structural elements.
The complete delivery set of the turnstile (Sect. 4.1) is packed in a transportation box, which keeps
it undamaged during the transportation and storage:
