9 OP-A
OPEN A contact - N.O.
TOTAL opening
Connect a button or other pulse generator which, by closing
a contact, commands TOTAL opening of both leaves.
10 OP-B
OPEN B contact - N.O.
PARTIAL opening
Connect a button or other pulse generator which, by closing
a contact, commands the PARTIAL opening.
on 2-motor systems = 100% of leaf 1 opening;
on 1-motor systems = 50% of leaf 1 opening.
When a logic requiring a CLOSE (
b
,
C
) input is selected, the,
OPEN B input automatically becomes CLOSE - N.O. (leaves
closing command).
To install more than one OPEN A or OPEN B pulse generator, connect the N.O. contacts in
parallel (see related Fig.)
11 STOP
STOP contact - N.C.
Connect a button or other pulse generator which, by opening
a contact, stops movement of the automated system.
To install more than one STOP device, connect the N.C. contacts in series (see related Fig.).
If stop devices are NOT connected, jumper the terminals STOP and GND.
12 FSWCL
FSW CL contact - N.C.
closing safety
Connect a photocell or other device which, by opening a con-
tact, reverses the movement of the automated system during
opening (FSW OP) or during closing (FSW CL).
13 FSWOP
FSW OP contact - N.C.
opening safety
To install more than one safety device, connect the N.C. contacts in series (see related Fig.).
If safety devices are NOT connected, jumper terminals FSW CL and FSW OP and GND if the
FAIL-SAFE safety is not active; otherwise jumper FSW CL and FSW OP and OUT1 (FAIL-SAFE).
