Start-Up
Give a short opening impulse by strapping the impulse input and adjust if necessary
as follows. See also illustration on page 37.
1. Set the hold open time with the potentiometer on the Control Unit.
2. To adjust the
opening speed
.
a Adapt the High Speed Opening (HSO), to the existing traffic situation. Turning
clockwise decreases the speed.
b The Low Speed Opening (LSO), needs to be adjusted only if the door is
extremely heavy. Turning clockwise decreases the speed.
Note!
If it is hard to obtain an even and smooth braking, the opening torque
(pump pressure) must be reduced.
3. Adjustment of the
closing speed
.
a Adjust the Low Speed Closing (LSC) as low as the traffic situation allows.
Turning clockwise decreases the speed.
b If a higher closing speed is required, open the High Speed Closing Valve
(HSC) (closed from factory).
Note!
If the installation requires adjustment of the closing torque follow the
instructions on page 37.
4. Adjust the
opening angle
by using the
limit switch
. The limit switch is slid into a
groove in the hydraulic unit and tightened with a lock screw. By moving the limit
switch sideways, the opening angle is changed.
Note!
To make the adjustment easier, the limit switch can be moved to the under-
side of the hydraulic unit. Any of the grooves at the motor side of the outgo-
ing shaft can be used.
5. If an electric strike or panic hardware is installed, additional
“lock-kick”
can be
obtained during the last 5° of the closing cycle by adjusting the LK screw on the
hydraulic unit. This screw is normally closed. Adjust by opening the screw 90°
and check the function.
Note!
Opening the screw too much may delay the opening.
6. Connect the activation units.
7. Check that the installation complies with valid regulations and requirements from
the authorities.
8. Special care should be taken regarding entrapment between driven parts and sur-
rounding fixed parts.
