6.4 CONFIGURING MOVEMENTS AND TIMING
In BASIC PROGRAMMING
-
PA
OPEN A pause time ,
Pb
OPEN B pause time In op-
erating logics with automatic closing, the gate remains
open for the pause time (configurable specifically for
full or partial opening).
-
Mn
Number of motors Before carrying out the SETUP
procedure, the number of motors has to be configured
in order to specify single or two leaf operation.
-
FA
Opening limit switch ,
FC
Closing limit switch If
present, the limit switches must be enabled, either
for stopping or slowing down the leaf.
-
Cd
Leaf closing delay This function is used in 2-leaf
automations to prevent interference between leaves
and to handle any overlap.
In ADVANCED PROGRAMMING
-
bo
Maximum force at initial thrust time When it starts,
the motor works at maximum force for a few seconds,
ignoring the limits set in basic programming (
F1
,
F2
). Increase the time in the case of particularly
high friction.
-
Od
Leaf opening delay This function is used in 2-leaf
automations to prevent interference between leaves
and to handle any overlap.
6.5 ADJUSTING THE ANTI-CRUSHING
SYSTEM
Anti-crushing protection is obtained by limiting the
static force exerted by the actuator in the event of im-
pact with an obstacle. When an obstacle is detected,
the board also issues a REVERSE command.
The reverse movement (partial or complete, accord-
ing to function
IP
) is not active in the search for stop
space specified in function
r8
(automation stopped
by obstacle).
OBSTACLE DETECTION is carried out by checking the cur-
rent absorbed by the motor or by using the encoder
(if present).
- The fourth consecutive obstacle, which is detected
in the same direction and position, is defined as the
new mechanical stop of the leaf (when the obstacle
is removed, the original length of travel is restored
automatically).
The functions used for adjusting the anti-crushing sys-
tem are listed below. Some allow the static force or the
kinetic energy of the leaf on the obstacle to be limited;
others configure the reverse on obstacle. Adjust the
functions together, taking into consideration the con-
figuration of the automation and the conditions of use.
For example, in particularly windy areas, with panelled leaves, if
the obstacle detection system is ultra-sensitive or the sensitivity of
the anti-crushing system is too high, frequent unwanted reversals
can occur.
In BASIC PROGRAMMING
-
F1
Motor 1 Power ,
F2
Motor 2 Power Decrease the
value if you want to limit the static force in the event
of impact.
-
SP
Speed of the movement Decrease the value if
you want to limit the kinetic energy of the leaf on an
obstacle.
-
En
ENCODER If encoders are installed, they must be
enabled in order to detect obstacles.
-
US
Ultra-sensitive obstacle detection Recommended
for 24 V hydraulic actuators with encoder.
-
r8
Search for stop Reverse on obstacle is not active
in the search for stop space. SOFT TOUCH (
SF
) can be
enabled, if necessary.
In ADVANCED PROGRAMMING
-
IP
Reverse on obstacle Specifies the amount by which
the leaf is reversed: complete or for 2 s.
-
r1
,
r2
Slowdown Leaf1, Leaf2 Specifies the extent
of the leaf slowdown near the open / closed posi-
tions. Alternatively, the slowdown enabled limit
switch can be used (
FA
,
FC
in basic programming).
The slowdown allows you to limit the inertial forces and reduce the
vibrations of the gate when it is stopping.
-
EC
Anti-crushing sensitivity Specifies the speed
at which the anti-crushing system triggers after an
obstacle has been detected.
-
SF
SOFT TOUCH : the leaf reverses slightly after the
mechanical stop has been detected.
This function allows the impact forces to fall within the limits
indicated by current regulations.
