4.5.
ADJUSTING THE COUNTERWEIGHTS
The weight of the counterweights must be increased to
ensure smooth operation. If there is insufficient space to
add to the existing counterweights, remove them and
replace them with blocks of a higher specific weight. To
adjust the weights, release the operator and move the
door to half-open position (45°). The door should remain in
balance.
4.6.
DOUBLE APPLICATION
For garage doors from 3.50 to 5 m wide, two 593 operators
must be used. The maximum permitted height is 3 m. Install
following the same criteria as for a single motor (fig. 7).
5. STARTUP
5.1.
DIRECTION OF ROTATION
1.
Disconnect the electronic control unit from the power
supply.
2.
Unlock the operator, and manually move the garage
door to its half-open position (see section 6, manual
operation).
3.
Relock the system (see section 6, manual operation).
4.
Reconnect the power supply.
5.
Send an OPEN command and check that the garage
door opens correctly.
N.B.
If the first OPEN impulse causes the garage door to
close, invert the position of the black and brown wires
on the electronic control unit.
5.2.
ADJUSTMENT OF OPERATION TIME
Time the opening movement. On the electronic control
unit, select an operation time that is a few seconds longer
than that of the movement you have timed, in order to
obtain optimal hydraulic locking efficiency.
5.3.
ADJUSTING TRANSMITTED TORQUE
The 593 operator is fitted with an anti-crushing system to
stop door movement whenever an obstacle is encountered
during movement.
Start garage door opening and adjust operator torque by
means of the green screw
(V, fig.4).
Repeat the same
operation for door closing by means of the red screw
(R,
fig.4).
Correct adjustment is obtained when the door stops
with a torque of approximately
15 kg
measured on the
lower edge of the door.
To increase torque, turn the screws clockwise; to reduce
torque, turn screws anti-clockwise.
When you have completed the adjustment operations, fit
the bypass safety device on the operator by means of the
relevant screws, as shown in the figure below.
5.4.
TESTING THE AUTOMATED UNIT
After completing installation, attach the danger warning
labels between the transmission tubes and the telescopic
arms (figs. 6-7). Carry out a careful functional check of the
operator and all accessories connected to it.
Give the customer the “User guide” and demonstrate how
to use the operator correctly. Point out the potential danger
zones of the automated unit.
6. MANUAL OPERATION
Should the need arise to actuate the garage door manually
because of a power failure or malfunction, operate the
unlocking lever device as shown in
fig. 20
.
A customised key-operated emergency release can also
be installed outside
(fig.21)
(optional)
.

- Insert the key in the lock, and turn the key
anticlockwise
by
1 turn.
- Manually open or close the door.
7. RETURNING TO NORMAL OPERATION
To prevent an accidental impulse from actuating the garage
door during this operation, before you restore normal
operation, disconnect the system from the power supply.
lever (standard):
- turn the lever
clockwise
all the way.
customised key (optional):
- turn the key
clockwise
all the way;
- slowly turn the key
anticlockwise
up to the point where it
can be extracted.
