5.4. TERMINAL BOARD CN4
5.4.1. T
OTAL OPENING
"COM2 – OPEN A" terminals. Normally open contact. Connect, to these terminals,
any pulse generator (push-button, key selector, etc...) which by closing a contact,
generates a total opening or closing impulse of the gate. The operation of this contact
is defined by operating parameter "D", see paragraph 9.
• A total opening impulse always has priority over pedestrian opening.
• To connect several pulse generators, connect the devices in parallel.
5.4.2. P
EDESTRIAN OPENING
"COM2 – OPEN B" terminals. Normally open contact. Connect, to these terminals, any
pulse generator (e.g. push-button, key selector, etc...) which, by closing a contact,
generates a partial opening or closing impulse of the gate. Opening for pedestrians
corresponds to 30% of the memory-stored total opening.
• A total opening impulse always has priority over pedestrian opening.
• To connect several pulse generators, connect the devices in parallel.
5.4.3. S
TOP
"COM2 – STOP" terminals. Normally closed contact. Connect, to these terminals, any safety device (e.g. pressure
switch, edge etc...), which, by opening a contact, causes the gate to stop immediately and disables any automatic
function. The status of this input is signalled by LED "DL2". The gate resumes its memory-stored cycle only by means of
another total or partial opening pulse.
• If no STOP devices are connected, jumper connect the input.
• To connect several STOP commands, connect the devices in series.
5.4.4. C
LOSING SAFETY DEVICES
"COM2 – FSW CL" terminals. Normally closed contact. Connect, to these terminals, any safety device (photocell, safety
edge, pressure switch etc...) which, by opening a contact, affects the gate's closing motion, causing it to reverse to
the opening position. The status of this input is signalled by LED "DL3".
5.4.5. O
PENING SAFETY DEVICES
"COM2 – FSW OP" terminals. Normally closed contact. Connect, to these terminals, any safety device (photocell, safety
edge, pressure switch etc...) which, by opening a contact, affects the gate's opening motion, causing it to reverse to
the closing position. The status of this input is signalled by LED "DL4".
