PROGRAMMING
The control unit can be programmed by adjusting the trimmers (A-
E) and switches (F)
They are shown here below with their factory settings.

ADJUSTING THE TRIMMERS
Trimmer
Description
Sets the time between the end of an opening manoeuvre and the start of the next closing manoeuvre.
A
Pause
Only valid if the control unit is programmed in Automatic operating mode ("Table 6").
Adjusts the maximum speed of the boom from the start of movement to the slowing cam.
B
Speed
It must be set so as not to create jerking movements during normal operation; the movement must be as even as
possible.
Adjusts the intervention threshold of the obstacle detector from the start of movement to the slowing cam.
C
Force
If an obstacle is encountered, the manoeuvre is completely reversed. A brief reversal takes place after the third
consecutive intervention.
Adjusts the speed of the slowing cam up to the end of travel.
D
Low Speed
It must be set so as not to create jerking movements during normal operation; the movement must be as even as
possible.
Adjusts the intervention threshold of the obstacle detector from the slowing cam up to the end of travel.
In the event of an obstacle where no positions have been acquired or within the "non-reversal zone", the manoeuvre is

immediately stopped.
Where positions have been acquired or outside the "non-reversal zone", the manoeuvre is completely reversed.
A brief reversal takes place after the third consecutive intervention.

7.1 ADJUSTING THE TRIMMERS
The control unit has five trimmers (see "Figure 41"), which are de-
scribed in the following table.
m
To make the trimmer adjustment effective, switches
13 and 14 should be set to "OFF" before the adjust-
ment, and set back to "ON" once it is complete.
E
To assess the effect of the trimmer adjustments, it is advisable to
have the barrier mechanism perform some opening and closing
manoeuvres.
Do this operation manually (hold-to-run):
1.
set switches 13 and 14 (A) to "OFF"
2.
if you are doing this procedure for the first time, set all trim-
mers to the halfway point
3.
by acting on the devices connected to the Step-by-step,
Open and Close inputs, have the barrier mechanism per-
form some opening and closing manoeuvres: check that
15
the boom movement begins with a phase of acceleration,
14
followed by a constant speed, and that it starts the deceler-
13
ation phase 20° before the mechanical stop
12
4.
release the control button to immediately stop the manoeu-
vre: if the SbS (Step-by-Step) input is used as a control, the
first movement after the stop will be an opening manoeuvre
5.
adjust the trimmers so that the operation of the automated
system is as you require
6.
set switches 13 and 14 (A) back to "ON".
