The MEI module can be installed without any need for
programming(exceptfortheinputsreservedfortheGatecoder/
LimitSwitch,whichmustbeconfigured).Besuretoobservethe
allocation of the default inputs below:
IN6 - CLOSE = Closure command (N.O.)
This means any device (e.g. pushbutton) which
gives a command to close the leaf/leaves when
a contact is closed in “deadman” logic. In the
other logics, when the gate is open, on pause
or stopped, it gives the command to close the
leaf/leaves while it is inactive with the gate
closed or opening.
IN7 - SAFE CL = Safety edge closing (N.C.)
This input is specifically for connecting
pneumatic safety edges which intervene
during the closure phase.
Opening this contact during the closure phase
causes timed inversion (2 sec. subject to
modification) and then stops the movement.
ÜIf no devices are connected, jumper this
input to the negative (terminal “-” of MEI
module if the Failsafe is disabled, terminal 9
of 460P if the Failsafe is enabled).
IN8 - SAFE OP = Safety edge opening (N.C.)
This input is specifically for connecting
pneumatic safety edges which intervene
during the opening phase.
Opening this contact during the opening phase
causes timed inversion (2 sec. subject to
modification) and then stops the movement.
ÜIf no devices are connected, jumper this
input to the negative (terminal “-” of MEI
module if the Failsafe is disabled, terminal 9
of 460P if the Failsafe is enabled).
It is possible to connect devices which activate
simultaneously,suchasopeningand closing safety
edges(see connectionexamples insection 8).
If these safety devices activate during opening or
closing, they stop the gate.
For details of operation,refer toTable 9.
IN9 - EMERG = Panic device (N.C.)
This means any device (e.g. pushbutton) which
immediately opens the gate or barrier when a
contact is opened regardless of the state of
the other inputs.
Once the panic opening command has been
given, normal operation can be resumed only
by resetting the contact and turning the
electronic control unit off and then back on
again.
ÜIf no devices are connected, jumper this
input to the negative (terminal “-” of MEI
module).

IN10 -
GC1/FCA1 = Gatecoder 1 / Opening limit switch 1
This input varies according to the programming
performed (use of Gatecoder or Limit switch):
Gatecoder used
= GC1
This is the input for the signal coming from the
Gatecoder installed on the leaf connected to
the motor M1 (LEAF 1).
Limit switch used
= FCA1 (N.C.)
Input for Leaf 1 opening limit switch contact.
The limit switch is a device with an N.C. contact
which slows down the leaf connected to motor
M1 (LEAF 1) if the contact opens during the leaf
opening phase.
Gatecoder and Limit switch not used
In this case the input is not active.
IN 11 -
GC2/FCC1 = Gatecoder 2 / Closure Limit Switch 1
This input varies according to the programming
performed (use of Gatecoder or Limit switch):
Gatecoder used
= GC2
This is the input for the signal coming from the
Gatecoder installed on the leaf connected to
motor M2 (LEAF 2).
Limit switch used
= FCC 1 (N.C.)
Input for Leaf 1 closure limit switch contact.
The limit switch is a device with an N.C.
contact which slows down the leaf connected
to motor M1 (LEAF 1) if the contact opens
during the leaf opening phase.
Gatecoder and Limit switch not used
In this case the input is not active.
5. GATECODER

theexactpositionoftheleafforthegateonwhichitisinstalled.
Two-leaf gates require a Gatecoder for each leaf.
The GATECODER is compatible only with the 460P card.
Table 7 GATECODER technical characteristics
Power supply 24Vdc
Housing protection IP 66
Ambient temperature -20 °C +55 °C
Connection to 460P 3x0.35 mm2 cable length 1 metre
Functions Deceleration/anti-crushing
Installable on operators 402-422-400
By using a learning cycle during the 460P card programming
phase,theGatecoderslowsdowntheleafatthedesired point
during both closing and opening.
Furthermore the Gatecoder also constitutes an effective
electronicanti-crushingsafetydevice(whichcanbedisabled)
because if an obstacle is detected while the leaf is moving it
reverses the direction of movement.
The obstacle detection time before reversal of movement is
programmable(standard1 sec.).
