2.3.5) Testing the connections
!
The following operations entail working on live circuits;
most of these run on extra-low safety voltage so they are
not dangerous but some contain mains voltage which
means they are HIGHLY DANGEROUS! Pay the greatest of
attention to what you are doing and NEVER WORK ALONE!
• Power the unit and check that voltage between terminals 10-11 is
approx. 24Vac.
• Make sure that the "OK" LED, after flashing rapidly for a few sec-
onds, flashes at intervals of one flash per second.
• Now check that the LED's related to the N.C. (Normally Closed) con-
tacts are on (all safety devices active) and that the LED's related to
the N.O. (Normally Open) inputs are off (no command); if this is not
the case, check the connections and efficiency of the various
devices. The STOP input switches off both FCA and FCC LEDs.
• Make sure that the voltage between terminals 21-22 ranges from
9Vdc to 11Vdc
• Release the gate, take it to the halfway point and then block it; it is
now free to move in either the opening or closing direction
• Now make sure that movement occurs in the right direction, that is,
see whether the movement set on the unit corresponds to that of
the leafs. This check is of paramount importance, if the direction is
wrong, in some cases (in the "Semiautomatic" mode, for instance)
the "Automatic" system might appear to be working properly; in fact,
the "OPEN" cycle is similar to the "CLOSE" cycle but with one basic
difference: the safety devices are ignored in the closing manoeuvre
which is the most dangerous.

3) Adjustments

Adjustments can be made through trimmers or selectors that modi-
fy the following parameters:
TL TP
TLM
• WORKING TIME (TL):
These adjust the maximum duration of the opening or closing
manoeuvre.
To adjust the working times TL, select the "Semiautomatic" oper-
ating mode by setting Dip-Switch 1 to ON, then adjust the TL trim-
mer to halfway along the travel distance. Now run an opening and
closing cycle and, if necessary, readjust the TL Trimmer in order to
leave enough time for the whole manoeuvre plus a margin of about
2 to 3 seconds.
If the TL trimmer is at maximum and there still is not enough time
to perform the entire manoeuvre, cut the TLM jumper to increase
the working time.
The modification of the working time will be effective starting with
the next opening manoeuvre.
If you wish to use the deceleration function (dip-switch 8), see the
notes (chapter 6.1) on the working time adjustment method.
• PAUSE TIME (TP):
In the "Automatic" mode, this adjusts the delay between the end of
the opening manoeuvre and the beginning of the automatic closing
manoeuvre.

• To see whether or not the direction of rotation is correct, give a
short impulse to the Open input, and make sure that the automat-
ic system moves in the opening direction; if this movement is
incorrect, proceed as follows:
- Turn the power off
- Exchange the wires that power the motor ("open" with "close")
- Once this has been done, check whether the direction of rota-
tion is correct by repeating the last operation.
• Make sure that the limit switches (if any) are properly connected;
move the limit switch lever and see whether the related limit switch
is triggered (switches off the corresponding LED on the control unit).
• Check the operation of the "Constant resistance Stop" input (e.g.
sensitive edge), if used:
Start an opening manoeuvre and check whether the automatic
movement stops immediately and briefly reverses direction after
the device connected to the input is triggered.
Repeat this test for the closing manoeuvre.
The "OK" LED located in the centre of the board microproces-
sor has the task of signalling the status of the internal logic: regular
flashing at 1 second intervals indicates that the internal microproces-
sor is active and waiting for commands. When the microprocessor
recognises a variation in the status of an input (whether it is a com-
mand or a function Dip-Switch input) it generates a rapid double flash
even if the variation does not have any immediate effects. Extremely
rapid flashing for 3 seconds means that the control unit has just been
powered and is carrying out internal testing.
To adjust Pause Time TP, select the "Automatic" operating mode
by moving Dip-Switch 2 to ON and adjust the TP trimmer as
required. Then carry out an opening manoeuvre and check the
time elapsed before "Automatic" closing manoeuvre.
• FORCE (F):
The control unit features a selector switch that enables you to ad
just the FORCE (F) of the motor on 5 levels: 30/45/60/80/100% .
Take great care when adjusting this selector switch, as this may
affect the level of safety of the automatic system. Trial by error is
required to adjust this parameter, measuring the force applied to
the leaf and comparing it with regulatory values.
