safety devices and stop the movement of the gate leaves
(fig. 3).
The 410 MPS card has an additional FAIL-SAFE device which
serves to check that the N.C. contact on the photocell
receiver is working efficiently before any operation(Can
be disabled through bridge Fig. 1 ref.13) .
N.B.
: If the
Opening safety devices
are engaged when the
gate is closed, they prevent the leaves from opening.
If the
Closing safety devices
are engaged when the gate
is open, they prevent the leaves from closing.
OP. - Opening safety device contact (N.C.)
: in the
A-S-E-EP-AD
logics, during the opening phase the safety devices stop
the movement of the gate leaves; when they are
disengaged the opening movement recommences. They
do not engage during closure.
N.B.: If opening safety devices are not connected, jumper
inputs OP and FSW TX
(Fig. 4).
The purpose of the opening safety devices is to safeguard
the zone behind the gate leaves (A, fig. 3).
CL. - Closing safety device contact (N.C.)
: in the
A-S-E-EP-AD
logics, during the closing phase the safety devices reverse
the direction of movement of the gate leaves, or they stop
the movement of the leaves then reverse direction when
they are disengaged (see microswitch
SW4
settings). They
do not engage during the opening cycle.
N.B.: If closing safety devices are not connected, jumper
inputs OP and FSWTX
(fig. 4).
The purpose of the closing safety devices is to safeguard
the zone in which the leaves move during the closing cycle
(B, fig. 3).
If the Fail-Safe function is not used, see cabling at page 4
for connections of photocells.
Important: for further information on the operation of the safety devices, see table 3.
Application examples
The following are the commonly used connection arrangements (enable fail -safe):
