4.1 Terminal board J1 (inputs)
OPEN - Open" command (N.O. - terminal 3): means any pulse
generator (e.g. button) which, by closing a contact, commands
opening and/or closing of the barrier.
CLOSE - Close" command (N.O. - terminal 4): means any pulse
generator (e.g. button) which, by closing a contact, commands closing
of the barrier.
FSW - Safety contact when closing (N.C. - terminal 5): the purpose
of the closing safeties is to protect the area affected by the movement
of the barrier during the closing phase, reversing its motion. They
never trip during the opening cycle.
The closing Safeties, if engaged when the automated system is open,
prevent the closing movement.
If CLOSE safety devices are not connected, jumper
terminals FSW and GND (Fig. 26) and leave the FAILSAFE
function (parameter
on the default value (disabled)
STP - STOP contact (N.C. - terminal 6): means any device (e.g.
button) which, by opening a contact, can stop movement of the
automated system.
If STOP safety devices are not connected, jumper
terminals STOP and GND (Fig. 26)
EMR - Emergency contact (N.C. - terminal 7): means any device
(e.g. switch) which, if activated in a situation of emergency, will open
the barrier until the contact is restored. When activated, this input has
priority over any other command.
If emergency safety devices are not connected, jumper
terminals ALM and GND (Fig. 26)

4.1.1 Connecting the safety devices
The E680 control board features an input for closing safety devices,
which trip during closing of the automated system, provided to protect
the gate area from the risk of impact.
These devices must use a signal with "N.C." contact, and must be
connected in series to the relay photocells that may be installed on
the system, as shown in Fig. 23 to Fig. 26.

safety enabled: in addition to making the connection as
shown in the diagram, it is necessary to set in Advanced

FAILSAFE safety
Fig. 26: connection of no relay safety device
4.1.2 Connecting BUS photocells
Up to 8 pairs of photocells can be connected to the E680 control board
using BUS technology. The connection must be made in parallel,
on terminal board J6, using a single power/communication line, as
shown in Fig. 27.
