16 - READING OF CYCLE COUNTER
PD21 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 thatcannot
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 hereafter 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. 1300 cycles
before the next service request.
Area 1
is the reading of the total number of completed cycles;
through
h
and
i
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
h
or
i
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.
16.1 - 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.
