4 = -FSW TX = Negative pole for power supply to photocell transmitters
Separate connection of the negative pole of the transmitters makes it possible to use the Failsafe control on the
photocells, thus increasing the system's safety level.
5 = FCA = Opening Limit-switch contact (N.C.)
The opening limit-switch consists of a micro-pushbutton which, activated by the cam when the door reaches open
position, stops movement immediately or, according to programming, after 3 sec.
6 = FCC = Closing Limit-switch contact (N.C.)
The closing limit-switch consists of a micro-pushbutton which, activated by the cam when the door reaches closed
position, stops movement immediately or, according to programming, after 3 sec.
For control unit operation, both limit-switches must be connected.
7 = FSW OP = Opening Safety Devices contact (N.C.)
Safety devices are all devices (photocells, sensitive edges,…) with N.C. contact, which, if there is an obstacle in the
area they protect, operate by stopping or reversing the door opening movement (see chap.7.2 - Advanced
programming).
They have no effect during the closing stage.
If the opening safety devices are engaged while the door is closed, they inhibit any Open pulse.
To install several safety devices, connect the N.C. contacts in series.
If no opening safety devices are connected, jumper connect "FSW OP" to the inputs common contact.
8 = FSW CL = Closing Safety Devices contact (N.C.)
Safety devices are all devices (photocells, sensitive edges,…) with N.C. contact, which, if there is an obstacle in the
area they protect, operate to reverse door closing movement. They have no effect during the opening stage, except
in the Ad function (see chap.5.3.1. - Advanced programming).
If the closing safety devices are engaged while the door is open, they inhibit any Open pulse.
To install several safety devices, connect the N.C. contacts in series.
If no closing safety devices are connected, jumper connect "FSW CL" to the inputs common contact.
9 = ENCODER = Input for encoder signal
The signal received from the encoder must be connected to this terminal. To supply power to the encoder, connect
the remaining two wires to terminals “1 - 3” observing the polarity indicated on the board.
The control unit will not operate without an encoder
For two-motor applications, the encoder must be applied only to motor 1 (the one with the unit)
10 = OPEN = OPEN Command (N.O.)
Any device (push-button, detector,…) which, by closing a contact, supplies an opening (or closing) pulse to the door.
To install several Open devices, connect N.O. contacts in parallel.
5.1.4. CONNECTOR J4 (low voltage)
Connector J4 is used for rapid connection of RECEIVING boards. The receiver board must be inserted with the components
facing the board.
Insert and remove the boards after cutting power.
6. SIGNALLING LEDs
A two-digit display is installed on the board. During normal operation, it
indicates the status of the inputs. Fig.4 shows the exact correspondence
between the horizontal segments (we will call them LEDs from now on) of
the display and the inputs.
The table below indicates the status of the LEDs in relation to the status of
the inputs.
