11 - READING OF CYCLE COUNTER
PD19 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:
tot
Cont
• A totalizing counter for completed opening cycles thatcannot be zeroed (option
of item
)
SErv
Cont
• A downward counter for the number of cycles before the next request for service (option
of item
).
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.
and i keys, you can alternate the display of thousands or units.
Area 1 is the reading of the total number of completed cycles; through
Area 2 is the reading of the number of cycles before the next request for service: its value is rounded down to the hundreds.
or i key, the current counter value will be rounded up or down to
Area 3 is the setup of this latter counter; if you press once
thousands, any following pressure will have the setup be increased or decreased of 1000 units. The previous displayed count will get lost.
11.1 - 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.
