Adjustments can be made through trimmers that modify the follow-
ing parameters:
WORKING TIME (TL1 TL2):
These adjust the maximum duration of the opening or closing
manoeuvreofmotor1(TL1)andmotor2(TL2).

the gate is closed.
If gearmotors with electric limit switches or limit stops are used,
adjust these switches or stops to maximise the opening or closing
range of a leaf.
ToadjusttheworkingtimesTL,selectthe“Semiautomatic”operat-
ing mode by setting Dip-Switch 1 to ON, then adjust the TL trimmers
to halfway along the travel distance. When these adjustments have
been made, execute an opening and closing cycle; if necessary also
adjust the TL trimmers so that there is enough time to execute the
entire manoeuvre and still leave a margin of 2 or 3 seconds before
theelectriclimitswitches(onthemotorswithlimitswitches)orthe
limit stops cut-in.
In order to check when the working time for the two motors termi-
nates, check whether the Motors ON LEDs, located on the control
unit,haveswitchedoff.(TheLEDswillswitchoffwhentheWorking
Timefortherespectivemotorisup).
If the TL trimmers are at maximum and there still is not enough time
to perform the entire manoeuvre, cut the TLM1 jumper to increase
the working time of motor 1 and cut the TLM2 jumper to increase
the working time of motor 2. These jumpers are located alongside
the corresponding trimmers.
IfyouwishtousetheDECELERATIONfunction(Dip-Switch8On),
adjust the working time trimmers so that the motors begin the decel-
eration stage approximately 50 - 70cm before the opening or closing
limit stops are reached.
OPENING TIME DELAY (TRA) AND CLOSING TIME DELAY
(TRC):
If the gate has two leaves that might jam if they start moving simulta-
neously, or that might overlap when closing, you need to adjust the
OpeningTimeDelaytrimmer(TRA)ortheClosingTimeDelay(TRC)
trimmer to overcome these problems.
The TRA trimmer must be adjusted to ensure that the leaf moved by
thesecondmotorisoutoftherangeoftheleafmovedbytherst
motor when the latter starts moving.
The TRC trimmer must be adjusted to ensure that, during the closing
operation, the leaf moved by the second motor reaches the end of
itstravelaftertherstmotorhascompleteditsclosingmanoeuvre.
PAUSE TIME (TP):

the opening manoeuvre and the beginning of the closing manoeuvre.
FORCE (F):
TakegreatcarewhenadjustingtheFORCE(F)trimmer,asthismay
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.
BALANCING manoeuvre times (BAL):
The BALANCE trimmer on this control unit enables a differentiation
between the work time between leaf opening and closing manoeu-
vres.
This is useful when the motor has different speeds in the two direc-
tions, such as in the case of hydraulic motors or when the gate leafs
are offset in opening and closing, causing different force levels and
thus requiring different travel times within the same space.
Therefore if the gate is offset in closing, the opening manoeuvre
may terminate before reaching the mechanical stops, in which case
rotate the BAL trimmer clockwise (Op) to increase the opening
timeuntilthedecelerationstartsatthesetpoint(50cmbeforethe
mechanicalstop)andthemanoeuvrelastsforafurther3-5seconds
after the leafs have reached the mechanical stops.
On the other hand, if the gate is offset in opening, balance by
rotating the BAL trimmer anti-clockwise (Cl) to extend the closing
manoeuvre time.
If the trimmer is positioned exactly at the centre, the opening and
closing manoeuvres will have the same work time.
