ENGLISH
When you have made the connections between the 578D
equipment and the on-board operator interface board, and
have adjusted the limit-switches (see operator instructions),
check opening direction as follows:
•
Cut power to the system.
•
Release the operator and partially open the door.
•
Lock the operator, power up the system again and command
opening. If the door begins its closing movement, change
opening direction (see Par.5.1). After you have changed it,
return to viewing automated system status, and then power
down and power up the equipment.
NOTE -
For perfect installation of the 578D equipment, using
sectional doors operator 541, take care over the following
aspects:
OPERATING LOGIC (
LO
) :
If you wish to control the operator 541 by using an UP and
DOWN push-button, you have to use the following logics: B ,
C , B/C . (REFER TO THE TABLES OF THE LOGICS)
DECELERATION BEFORE (
rP
) AND AFTER TRAVEL-STOP (
rA
)
:
NOTE:
NEVER INCREASE THE DEFAULT VALUE OF THE AFTER
TRAVEL-STOP (
rA
), SET ON THE CONTROL BOARD
The reduction of the operator’s speed during deceleration
also reduces the force it can deliver. If the door is not well
balanced, 541 may not be able to perform deceleration at
opening (door with strong tendency to close) or at closing
(door with strong tendency to open), because the delivered
force is not sufficient to overcome the imbalance.
In this case,
0 must be set as the pre- and post-limitswitch deceleration
value (see advanced programming in Par.5.2),
because a
different value could prevent the limit-switch being reached
or prevent reversal of motion following tripping of the anti-
crushing system.
ANTI-CRUSHING SAFETY DEVICE DURING CLOSING:
although it has an Encoder sensor, the 541 operator cannot
intrinsically guarantee this safety device, because it is not
fitted directly on the door, but acts on the rope winding
shaft. Therefore, the ENCODER sensor cannot detect any
obstacle during closing. In this connection, we recommend
to observe current legal regulations for protecting the lower
part of the door.
NOTE -
For motors with an inductive sensor (746 and 844) take
care over setting post-limitswitch deceleration and braking:
if deceleration is too long or braking is insufficient, the plate
fitted on the gate rack can go beyond the sensor until it
disengages the sensor. When the gate is stopped, check if
only the limit-switch involved is engaged. The relevant LED
must be off. If it went off and then re-lighted, or if both the
LEDs of the limit-switches are off, reduce the post-limitswitch
deceleration value and/or increase braking value.
At end of programming, run a few complete cycles to check if
the automated system and the accessories connected to it are
operating correctly, giving special attention to safety devices,
operator thrust force adjustment, and to the anti-crushing
device (Encoder sensor). Hand over the "User's guide" page (in
the operator instructions) to the customer, and describe how
the system works, as well as the operator release and locking
operations indicated in the said guide.
DECELERATION BEFORE (
rP
) AND AFTER TRAVEL-STOP (
rA
)
:
Always set to 0 (ZERO) the deceleration parameters for the
values: before and after travel-stop
rP
= 0
rA
= 0
FINAL BRAKING (
br
) :
Always set to 0 (ZERO) the final braking parameter
br
= 0
