READING OF CYCLE COUNTER
control unit counts the completed opening cycles of
the barrier 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 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 about no. 1300 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.
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.

WARNING: service operations shall be carried out by
qualified staff only.
