ADJUSTMENTS

Give a short opening impulse by strapping the impulse input and adjust if necessary
as follows.
Adjustment of the opening speed
Adapt the high speed opening HSO, to the existing traffic situation. Turning clockwise
decreases the speed.
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.
Adjustment of the closing speeds
Adjust the low speed closing LSC as low as the traffic situation allows. Turning clockwise
decreases the speed.
If a higher closing speed is required, open the high speed closing valve HSC (closed from
factory).
An additional “lock-kick” can be obtained during the last 5° of the closing cycle by adjusting
the screw LK 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.
Opening angle
Fine-adjust the opening angle by means of 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 underside of the
hydraulic unit. Any of the grooves at the motor side of the outgoing shaft can be used.
Closing force
To comply with authority requirements or to overcome over/under pressure the closing torque
can be adjusted. The closing torque (spring force) is adjusted by means of an Allen screw
placed at the end of the spring tube. The end plate has to be dismantled. Turning the screw
clockwise increases the force. One turn equals a torque change of approx. 1 Nm (28 turns
from min. to max.). The door must be in open position when extremely low torque is adjusted.
Opening torque
If the closing torque (spring force) has been changed, or if the door does not open to its full
extent, the opening torque (pump pressure) must be adjusted as follows:
1. The factory set torque for DB104 is 70 Nm and for DB105 40 Nm at a door opening angle
of 0-2°.
2. Measure the opening torque by using a spring balance and adjust if necessary.
The torque is adjusted by means of an Allen screw placed on the pump. Turning clockwise
increases the opening torque/pump pressure. One turn equals a torque change of approx.
30 Nm.
