Reading Of Cycle Counter; Signal Of Service Required; Obstacle Sensor Operation - V2 ELETTRONICA City1 Mode D'emploi

READING OF CYCLE COUNTER

City1 control unit counts the completed opening cycles of the
gate and, if requested, it shows that service is required after a
fixed number of cycles.
There are two counters available:
• A totalizing counter for completed opening cycles that
cannot be zeroed (option "tot" of item "Cont")
• A downward counter for the number of cycles before the
next request for service (option "SErv" of item "Cont"). This
counter can be programmed according to the desired value.
The side scheme shows how to read the totalizing counter, how
to read the number of cycles before the next service is required
as well as how to program the number of cycles before the
next request for service (as for the example shown, the control
unit completed no. 12451 cycles and there are no. 1322
cycles before the next service request.
Area 1 is the reading of the total number of completed cycles;
through Up and Down keys, you can alternate the display of
thousands or units.
Area 2 is the reading of the number of cycles before the next
request for service: its value is rounded down to the hundreds.
Area 3 is the setup of this latter counter; if you press once UP
or DOWN key, the current counter value will be rounded up or
down to thousands, any following pressure will have the setup
be increased or decreased of 1000 units. The previous
displayed count will get lost.

Signal of service required

As soon as the counter of cycles before the next request for
service is zero, the control unit shows the request for service
through an additional 5-second pre-blinking.
WARNING: service operations shall be carried out by
qualified staff only. This signal will be repeated at each
opening cycle, until the installer enters into the counter reading
and setup menu, and possibly programs the number of cycles
after which the next service will be requested.
In case no new value is setup (that is to say that the counter
value is left at zero), the signalling function for the service
request will be disabled and no signal will be repeated anymore.

OBSTACLE SENSOR OPERATION

City1 control unit is equipped with a sophisticated system that
allows detecting if there is any obstacle stopping the door
motion. The sensitivity of this system can be adjusted through
the Sens menu: the higher is the setup value, the prompter will
be the control unit intervention if there is any obstacle. If you
set on 0, obstacle detection will be disabled.
WARNING: apart from any setup sensitivity value, this
system will detect an obstacle only if the door is stopped;
therefore, no obstacle braking the door without stopping it will
be detected. In addition, this system does not work when the
doors moves at slowed down speed.
The control unit reaction in case an obstacle is detected
depends on the t.rAL menu setup and on the moment when
such obstacle is detected.
Slowing down disabled
The door motor on which an obstacle is detected will stop
pushing and, for a second fraction, it will be given the
command to go backwards, so not to keep its gears under
stress. If t.SEr menu is set to 'no' (that is to say, no electric
lock) and an obstacle is detected during the last 3 seconds of
the closing phase, there will be no reversal, to allow the gate
completing its closing.
Slowing down enabled
Obstacle detection will be performed only if the door moves at
a normal speed. Both doors will stop and they will be given the
command to go backwards for 3 seconds, to take out the
obstacle detected. The following Start command will let the
former door motion start again. In case the slowing down
phase has already begun, no obstacle will be detected and this
kind of situation cannot be considered as dangerous since the
motor, when working according to its slowing down function, will
push the obstacle with a very low pressure.
