11 - EMERGENCY DEAD MAN OPERATION
This operational mode can be used to move the gate in DEAD
MAN mode in particular cases, such as installation/maintenance or
in the case of malfunctioning of photocell, edge, limit switches or
encoder.
To activate the function the START command must be pressed
3 times (presses must last at least 1 second; the pause between
commands must last at least 1 second).

The fourth START command activates the gate in MAN PRESENT
mode. To move the gate keep the START command pressed for
the duration of the operation (time T).
The function will automatically turn off after 10 seconds of
inactivity of the gate.

NOTE: if the
parameter is set as
command (from the terminal block or remote control) moves the
gate in the open and closed directions alternatively (unlike the
normal DEAD MAN mode).
12 - READING OF CYCLE COUNTER
PD20 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 thatcannot
tot
be zeroed (option
of item
• A downward counter for the number of cycles before the next
request for service (option
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;

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; on first pressing the
h
i
or
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.

12.1 - 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.
