PERSONAL PROTECTIVE EQUIPMENT
F
Install the board cover before switching on the power supply.
!
During operation there is a risk of fingers and hands being trapped between
the rack, pinion and cover.
Under certain conditions, as a result of prolonged continuous operation,
the body of the gearmotor can reach high temperatures. Avoid touching it.
SET-UP PROCEDURE
Carry out the steps, referring to the relative paragraphs and § 10 for
the accessories.
1.
With the gearmotor released, move the leaf manually to the halfway position.
2.
Turn the power supply on and check the status of the LEDs
(§ Diagnostics).
3.
Install the limit switches on the rack
.
4.
Set the opening direction
: function
d I
in basic programming.
The opening direction is established by looking at the 746 E R from the
release device side.
5.
Program the pre-limit switch decelerations
: function
r P
in advanced
programming.
The pre-limit switch deceleration reduces the inertia of the gate, allowing the impact
forces to fall within the limits indicated in the standard.
The deceleration is carried out only after a complete cycle has taken place
from one limit switch to the other.
Each time the power is turned on/restored, the cycles carried out before
the complete movement take place at normal or slow speed according to
parameter
S r
in advanced programming.
6.
Adjust the stop positions
:
-
Adjust the position of the limit switches on the rack
-
Set the post-limit switch deceleration and the braking so that the
gate stops in the correct positions: functions
r A
and
b r
in
advanced programming. The leaf must stop a few centimetres
before reaching the mechanical stop.
The post-limit switch deceleration is carried out as soon as a limit switch on the gate
engages the sensor (the corresponding LED on the board turns off). Braking takes
place after the deceleration.
Set the values so that a stop position is obtained in which the sensor is not released
by the limit switch. Excessive braking causes the leaf to move backwards after it has
stopped.
7.
Set the time-out
: function
t
in advanced programming.
The time-out prevents the motor from overheating if the limit switch fails to en-
gage: set a time of approximately 10 s longer than the travel time measured between
one limit switch and the other.
8.
Adjust the anti-crushing system (§ 8.4)
.
9.
Complete the basic / advanced programming
, according to the required
operating characteristics.
10.
Memorise the radio controls
, if used, following the specific instructions.
11.
Make sure that the automation is working properly with all the devices installed.
12.
Install the cover
.
