11 - READING OF CYCLE COUNTER
The PD22 control unit counts the completed opening cycles
and, if requested, it informs the user after a preset number of
manoeuvres that maintenance operations are required.
There are two counters available:
• A totalizing counter for completed opening cycles thatcannot
be zeroed (option tot of item Cnt )
• A downward counter for the number of cycles before the next
request for service (option SErv of item Cnt ).
To access the menu follow these instructions:
1. Press and hold down the OK key until the -Cnt appears on
the display
2. Release the OK key: the display will show tot
11.1 - CYCLE COUNTER
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.
11.2 - 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.
m WARNING: service operations shall be carried out by
qualified staff only.
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; on first pressing the
h or i key the current value of the counter is rounded to the
thousand, each press after this increases the setting by 1000 units
or decreases by 100. The previous displayed count will get lost.
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.
