READING OF CYCLE
COUNTER
Pd8 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.
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.
