Internal command
: any control device (pushbutton,
photocell, sensor, etc.) which, by closing a contact, can
command an opening cycle of the system from inside.
10. External command
: any control device (pushbutton,
photocell, sensor, etc.) which, by closing a contact, can
command an opening cycle of the system from outside.
Fig. 17 shows the control device connection. To install
more than one internal/external control device, connect
the N.O. contacts in parallel.
Connecting microwave radar / passive infrared sensors.
In the conventional configurations the control units are
microwave radar and/or passive infrared sensors. To
connect the FAAC sensors/radar units equipped with a 5-
pole electrical cable, refer to fig. 18.
11. Emergency control (fig. 19/a):
any control device (normally
a pushbutton) which, by opening a contact, commands
an emergency closure of the system. Alternatively this
input can be used to command emergency opening by
programming the system in a suitable manner using the
CODIS programming unit (optional).
To install more than one emergency control device,
connect the N.C. contacts in series.
N.B.
: If emergency control devices are not connected,
jumper inputs
11
and
15
.
Activating function no. 6 at CODIS programming level III
enables the emergency control to be activated by closing
a N.O. contact.
In this case, in order to install more than one emergency
control device, connect the N.O. contacts in parallel.
12. STOP safety control (fig. 19/a):
any device (safety sensor,
photocell, etc.) which, by opening a contact, has a safety
effect on the operating cycle. In particular, this safety
device interrupts the opening/closing movement of the
door.
When the safety device is disengaged, the door resumes
its opening/closing movement and continues to the end
of the cycle.
To install more than one STOP safety device, connect the
N.C. contacts in series.
N.B.:
If STOP safety devices are not installed, jumper inputs
12
and
15
.
13. CLOSURE safety command (fig. 19/a):
any device (safety
sensor, photocell, etc.) which, by opening a contact, has
a safety function on the closing movement of the door.
The safety device causes an immediate reversal of the
closing movement of the door, but has no effect on the
opening movement of the door.
To install more than one CLOSURE safety device, connect
the N.C. contacts in series.
N.B.:
If CLOSURE safety devices are not connected, jumper
inputs
13
and
15
.
Connection of MINISWITCH photocells
The MINISWITCH photocells can be used as a safety device.
POSITION “1”: AUTOMATIC
When an internal/external command is given, the door opens and then re-closes after the pause time.
POSITION “0”: MANUAL/NIGHT
The position “0” can be used to select two different operating functions according to the programming carried out on the 961
B-E programming unit (see section 5.3.3).
The two functions are:
MANUAL:
The door can be opened manually. The return spring pulls the door closed again.
NIGHT:
The external command is inactive. The door can be opened solely by
activating the internal command (fig. 22) or EMERGENCY OPENING (fig. 19/a) input.
POSITION “2”: OPEN
When this function is selected, the door opens and remains open. The door can be closed only by activating the EMERGENCY
CLOSURE input (fig.19/a).

14. Accessories power supply (+24 Vdc)
15. - 16. Accessories power supply (0 Vdc)
17. Status signal output: Common (fig. 20)
18. Door open signal output
(max. contact capacity 0.5 A / 24
Vdc) (fig. 20)
19. Door closed signal output
(max. contact capacity 0.5 A /
24 Vdc) (fig. 20).
Terminals 17/18 and 17/19 can be used to power two 24
Vdc (max. 0.5 A) warning lamps to provide door open and
door closed signals respectively (fig. 20).
20. - 21. Alarm signal output
(max. contact capacity 0.5 A / 24
Vdc).
Terminals 20 and 21 can be used to power a 24 Vdc (max.
0.5 A) warning lamp for remote signalling of an alarm
condition (fig. 21).
The operator signals a malfunction by means of an acoustic
alarm from a buzzer (see Table 6).
22. “KEY” opening command (fig. 22):
any device which, by
closing a contact for more than 3 seconds, commands
door opening in any operating function selected.
To install more than one “KEY” command, connect the
N.O. contacts in parallel.
23. Output for “DOUBLE LEAF” application (fig. 22):
see section
9.2
24. Output for GONG acoustic signal / Output for “INTERLOCK”
application
(fig. 22):
When the CLOSURE safety device comes into operation, it
activates the output between terminals 14 and 24 for one
second at intervals of 0.5 seconds. The output is suitable for
controlling an acoustic signal (GONG). The maximum load
is 300 mA (fig. 22).
In the event of “INTERLOCK” operation, it is necessary to
activate function no. 3 at CODIS level III and use outputs 24
and 25 for the connection between the two operators
(see section 9.1).
25. 0 Vdc
26. - 27. - 28. PC connection:
These outputs allow for interfacing
with a PC, which if necessary can control a number of
doors from a single central unit (fig. 23).
For this application refer to the relevant technical manual.

N.B.:
To RESET, hold down the button for at least 4 seconds.

7. FUNCTION SWITCH
The 961 B-E operator has a 3-position function switch (0-1-2)
mounted on one of the end covers (fig. 1 - ref. 12). This cover
can be fitted on the right or the left as required (fig. 8).
The switch electrical connection is shown in fig. 13.
The selectable operating functions are shown in fig. 24.
