7.5 STARTING THE AUTOMATION
Start the automation following instructions for the E844 3PH board.
7.6 ADJUSTING THE ANTI-CRUSHING SYSTEM
The anti-crushing system is realised by a combination of the limitation
of static force exerted by the operator in the event of impact and the
reverse movement following the detection of the obstacle.
We suggest:
-
limit the static force to a value lower than 150 N
-
set the sensitivity of the obstacle detection system so that ob-
stacles are not detected by mistake
-
make sure that the anti-crushing system has been adjusted
correctly by using an impact force tester in accordance with
standard EN 12453
Refine the adjustments if necessary.
LIMITING THE STATIC FORCE
The static force is limited by adjusting the mechanical clutch.
F
The clutch must be adjusted with the power supply disconnected.
!
The 844 ER 3PH is supplied with the clutch adjusted for maximum thrust force.
1. Turn off the power supply and remove the protective cover from
the board.
2. Hold the drive shaft in position using a spanner and adjust the
screw of the clutch using a screwdriver (
):
(+)
turn clockwise to increase the force
(
–)
turn anti-clockwise to decrease the force
3. Put back the protective cover on the board and turn the power
back on.
OBSTACLE DETECTION
The electronic board determines the position of the leaf and the
speed of movement via the encoder and detects the presence of an
obstacle in the event of impact.
Adjust the sensitivity of the detection system (if it is too sensitive, it
can lead to obstacles to be detected by mistake): function
EC
in
advanced programming.
!
Do not disable the obstacle detection system.
