7.1 - Control unit
The control unit has a variety of factory settings which can be reprogrammed: this chapter describes the available functions and how to program
them. Also refer to chapter 8 ‘Further details’.
The control unit is equipped with micro-switches and trimmers (Fig.4):

TP Trimmer
This is used to adjust the 'Pause Time' parameter: it adjusts the time between the end of an Opening
manoeuvre and the start of a Closing manoeuvre.
Only if the control unit is programmed in 'automatic' operating mode (Table 5)
FL Trimmer
This is used to adjust the 'Working Force' parameter: it adjusts the maximum speed of the boom before
the boom starts the slowing down phase, set between the limit switch and the mechanical stop.
Adjustment: it must be set so as not to create jerking movements during normal operation; the move-
ment must be as even as possible.
FR Trimmer
This is used to adjust the 'Deceleration Force' parameter: it adjusts the slowing down speed performed
by the boom between the limit switch and mechanical stop.
Adjustment: it must be set so as not to create jerking movements during normal operation; the move-
ment must be as even as possible.
I Trimmer
This is used to adjust the 'Stop Ampere' parameter: it adjusts the intervention threshold of the obstacle
detection system on the control unit: the system intervenes both in opening and closing.
Note - Since the motor needs more power at the start of each manoeuvre (departure), the 'obstacle
detection system' is excluded.
Adjustment: it must be adjusted so that the boom stops or reverses its manoeuvre if a contrary action
is applied that prevents its movement
To assess the effect of the trimmer adjustments, it is advisable to have the barrier mechanism perform a few opening and closing manoeuvres:
do this operation manually (hold-to-run):
01. Set the micro-switches to 'OFF'
02. Provisionally adjust the trimmers:
- 'Stop Ampere' and 'Working Force' = maximum stroke
- 'Deceleration Force' = half way
03. By acting on the devices connected to the Step-by-step, Open and Close inputs, make the barrier mechanism perform some opening
and closing manoeuvres: check that the boom movement begins with a phase of acceleration, followed by a constant speed, and that
it starts the deceleration phase 20' before the mechanical stop
04. Release the command key to obtain the immediate stoppage of the manoeuvre: if the S.S (Step-by-Step) input is used as the com-
mand, the rst movement after the stop will be an opening manoeuvre
05. Adjust the trimmers so that the operation of the automated system is as you require
7.2 - Programmable functions
The control unit has a set of micro switches (PROGRAM SWITCH - Fig. 5) which activate functions to adapt the automation to the user's needs
as well as making it safer to use.
The micro-switches allow the user to select the various operating modes and programme the desired functions, as described in Table 5.
To activate/deactivate a function:
Micro switches: 1 ... 10 ACTIVATION = ON DEACTIVATION = OFF
IMPORTANT! - some functions are safety critical; make sure to check which function is safest.
