FUNCTIONS
5.1.
IxT Protection
The function is always active and protects the motor from overloads due to mechanical hardening or obstacles that
prevent normal door travel. If the current absorbed by the motor exceeds a certain threshold (about 5 A) for more
than 7 seconds, the board is disabled and remains in IxT alarm.
After a pause of about 15 seconds, the Drive closes the door at reduced speed.
5.2.
Vandal-proof Function
This function can only be activated if the light curtains are enabled by parameter G0 (
[Enabled L.C.]
if DISP801 is
used). If the light curtains connected to the Drive detect a persistent obstacle for a time longer than that set in the
parameter M6
→
G1 (
[LIGHT CURTAIN]
→
[Anti-V(sec)]
if DISP801 is used) the Drive commands a slow closure.
The closure is also signaled by an acoustic signal if G4 = 1 (
[Buzzer Nudge]
=
[YES]
if DISP801 is used).
By setting parameter G1 (
[Anti-V(sec)]
if DISP801 is used) = 0, the function is disabled.
5.3.
Light Curtains Vega B-LIFT 240 Safety Test
The function can only be activated if the light curtains are enabled by the G0 parameter (
[Enabled L.C.]
if DISP801 is
used). The function can be enabled by parameter M6 → G2 (
[LIGHT CURTAIN]
→
[Sec. Check]
if DISP801 is used).
If the safety test is enabled, when the door is fully closed the Drive performs a test on the light curtain in order to
verify if it is functioning correctly. If the test fails, the doors will close at low speed and the closure will be signaled by
an acoustic signal.
5.4.
Coupling Reopening on the floor
–
EN81-20/50
The function can be enabled by M7 → P0 = 1 (
[PAR. EN81-20/50]
→
[Enable REOPENING]
=
[YES]
if DISP801 is used).
If the reopening is enabled, when the
[CLOSE]
command is no longer active, after a few seconds (programmable) the
board reopens the door a few centimeters (programmable).
This small reopening is used to unlock the landing door so that you can reopen the door when from inside the car
when you are on the floor.
