15) The automationincludesanintrinsicanti-crushing device consistingofatorquecontrol which,however,mustbeinstalled
together with other safety devices.
16) The safety devices [e.g.: photocells, sensitive edges, etc…] protect any dangerous areas against Movement
mechanical risks, such as, crushing, dragging, or shearing.
17) Use of at least one indicator-light is essential for each system (e.g.: FAAC LAMP MINILAMP, etc.) as well as a sign
adequately fixed to the frame structure, in addition to the devices mentioned at point “16”.
18) FAAC accepts no responsibility regarding safety and correct operation of the automation, should components made
by manufacturers other than FAAC be used in the system.
19) Use only FAAC original spare parts for maintenance.
20) Do not make any alterations to the components of the automation.
21) The installer must supply full information regarding manual operation of the system in case of an emergency and hand
to the user of the system the “User’s Guide” included with the product.
22) Do not allow children or other persons to stand near the product while in operation.
23) Keep remote controls or any other pulse generator well away from children, to prevent the automation from being
activatedaccidentally.
24) The user must refrain from attempting to repair or adjust the system personally and should contact qualified personnel
only.
25) Anything not expressly provided for in these instructions is not permitted.

Ü Before attempting any work on the card (connections,
programming, maintenance), always turn off power.
Warning: If plugs J3 and J4 are disconnected, high voltage
may be present on the flashlight and motor outputs.

3.2. TERMINAL BOARD J2 (low voltage)
1 = OPEN A (N.O.) – Total opening
This is any pulse generator with N.O. contact which,
when activated, produces a gate opening movement.
In A, E and S logics, it commands both opening and
closing.
To install several Open A devices, connect N.O. con-
tacts in parallel.
2 = OPEN B (N.O.) – Opening for pedestrians / Closing
This is any pulse generator with N.O. contact which,
when activated in logics A, E and S, produces a gate
opening movement for pedestrians. In B and C logics,
it commands a closing movement.
To install several Open B devices,connect N.O.con-
tacts in parallel.
3 = STOP command (N.C.)
This is any device (e.g. a push-button) which, by open-
ing a contact, stops gate movement.
To install several stop devices,connect the N.C.con-
tacts in series.
ÜIf Stop devices are not connected, link the input to
the common contact (terminal 5) via a jumper.
4 = FSW closing safety devices contact (N.C.)
Safety devices are all devices (photocells, sensitive
edges, magnetic coils) with N.C. contact, which, if
there is an obstacle in the area they protect, operate
to interrupt gate movement. The purpose of the clos-
ing safety devices is to protect the gate movement
area during closing.
If the safety devices are tripped during closure, gate
movement is reversed, whereas they have no effect
during opening. If used when the gate is open or paus-
ing, closing safety devices prevent its closing.
To install several safety devices,connect the N.C.con-
tacts in series.
ÜIf closing safety devices are not connected, link
this input to the common contact (terminal 5) via a
jumper.
5 = Common contact for commands
6 = Negative of accessories power supply
7 = 24 Vdc (+) power supply for accessories
Max load of accessories is 500 mA.
To calculate absorption values, refer to the instruc-
tions for individual accessories.
9 = Warning light output (24Vac)
The maximum load of the warning light is 5 W.
For instructions on operation of the warning light, con-
sult microswitch programming.
ÜIf you cut out jumper LK1, you obtain a voltage free
contact between terminals 8 and 9 (see fig. 6).

4. PROGRAMMING
To program operation of automation, use the microswitches as
shown below.
ÜYou must press the RESET push-button after every program-
mingjob.
Function logics
The following are available:
A1/A2 = “Automatic” S1/S2 =“Safety”
E1/E2/B = “Semi-automatic” C = “Dead man”
Operation of automation in the different logics is indicated in
Tables 4-5-6-7-8-9-10-11.
Pause time
Pausetimeis waiting time inopenpositionbeforere-closingwhen

Pause times include pre-flashing if any
Operation of warning light
Usedto change the appearance ofthe warning light at closing
by making it flash.
Pre-flashing

• Condition ccausesanalarmsituation disabling any activity:
Normal operation can be restored only after eliminating the
alarmcause and pressing the RESET push-button (orturning off
powersupplymomentarily).
To have this condition signalled, the warning light must be
connected: the alarm is signalled by very rapidly flashing light
(0.25sec).
6. ROTATION DIRECTION CHECK
1) Release the operator, take it manually to mid-travel and re-
lock it.
2) Power up the system and then press the RESET push-button.
3) Give an Open command tothe operator, check if the gate
moves in opening direction and then press the RESET push-
button to stop the leaf moving.
4) Ifrotationdirectionisincorrect, change over wiring of cables
T1 and T3 of the electric motor.
