LOGIC ADJUSTMENTS
TRIMMER
TCA Trimmer for adjusting the pause (5-120 sec), or the time the door remains open with the
TCA is enable. The count begins at the end of the operating time for the opening phase or
when reaching the opening limit switch. It stops when a manual closing command is given
and is temporarily disabled when a stop command is given.
TL Trimmer for adjusting operating time (5-120 sec), or the time the overhead door takes to
complete a maneuver. The count begins each time a command is given. It is advisable to
adjust the time to a few seconds longer than is really necessary.
Note: the deceleration time can be fixed (1/3 or the work time) or adjustable:
With software version up to 3.00:
- with fixed deceleration enabled (DIP 4 set to ON - DIP 8 set to OFF), set the TL
to activate complete closure. If deceleration is disabled (DIP 4 set to OFF - DIP 8
set to OFF), reduce the TL accordingly, to compensate for the increased speed
on closure.
- with adjustable deceleration enabled (DIP 4 set to ON - DIP 8 set to ON), with
work time (TL) remains set at 48 sec. Adjust the trimmer TL to set the decelera-
tion time as required (0-48 sec).
With software version up to 3.10:
- with DIP4 set to OFF (no deceleration applied): the work time can be set from 4
to 48 sec.
- with DIP4 set to ON (settable deceleration applied): the work time is established
by the SETUP procedure.
WORK TIME AND DECELERATION SETUP PROCEDURE
By moving DIP4 from OFF to ON, or on power-up with DIP4 set to ON and the work time
not memorised, the stroke setup procedure is activated. Led DL7 flashes quickly.
PROCEDURE WITHOUT LIMIT SWITCHES INSTALLED:
1 Press the key AP/CH to start closure of the automation leaf.
2 When the leaf is closed, press the key AP/CH. The automation inverts movement and
starts opening.
3 Press AP/CH when deceleration is required
4 Press AP/CH when the leaf reaches the completely open position.
5 LED DL7 lights up permanently (procedure completed and parameters memorised).
Note: if the limit switches are not installed, "generous" time settings are recom-
mended.
PROCEDURE WITH LIMIT SWITCHES INSTALLED:
1 Press the key AP/CH to start closure of the automation leaf.
2 When the leaf reaches the closing limit switch, it must invert movement.
3 Press AP/CH when deceleration is required.
4 When the leaf reaches the opening limit switch, it must stop.
Note: STOP can be pressed at any time to repeat the procedure, starting from point
1.
FR obstacle detection sensitivity adjustment.
NOTE: by rotating the TRIMMER FR clockwise the sensitivity of the gearmotor to obstacles
diminishes and therefore the thrust force increases; vice-versa, by rotating it counter-
clockwise, the sensitivity of the gearmotor to obstacles increases and therefore the
thrust force diminishes.
RCM Selector for motor clutch adjustment, it has four positions for adjusting the motor torque
to four different levels. It is advisable to adjust this starting from a minimum value and in-
creasing said value if it is not sufficient to open the door, thus exerting the minimum torque
needed to move the door so that any accidental bumping against persons or property will
cause the least possible damage.
