Adjustment of spindle limit switch setting:
After wiring up the operator in accordance with the separate wiring diagram, make a test run:
Using the emergency hand chain, open the door halfway, or in the case of the quick release version,
uncouple the drive from the door and open the door halfway by hand. Press the "OPEN" button.
The door should open. If the rotational direction is wrong, reverse the phases. Close the door manually. Shift the red no-load
lever (A) to the front ("X" position) and unlock the driving plate (B) in the direction of the switch box. By means of the red
knurled wheel (C) to the right of the switch box, turn the switch spindle (H) so that the switch carriage (G) actuates the limit
switch (D) "CLOSE", until the red LED (K) on the mounting plate lights up. Relock the driving plate (B) and secure with the
no-load lever (A) (position "Z"). The lever must be heard to click into place!
Re-adjust the setting if required with fine setting (M) on the switch carriage (G); Turn the adjusting cam clockwise: the drive
cuts off earlier. Open the door to its end of travel open position, and with the knurled wheel (E) on the adjusting spindle (l) set
the limit switch (F) "OPEN" until the green LED (L) on the mounting plate lights up.
Check the door's end of travel positions, re-adjusting if necessary as described above.

Pulling the emergency hand chain, disconnects the drive from
the electricity supply.
Important! After actuation of the emergency hand
chain an automatic reset is carried out and
the operator is switched on electrically.
Afterwards, it is essential to screw the emergency hand
chain firmly in place with the wing nut as shown in the
detail to fig. 5.
Before connecting the emergency hand chain to the supplied
chain link, it is important to ensure that the chain is not fitted
twisted.
If the chain is twisted, malfunctions may occur when the hand
chain is operated.
When operation the emergency crank handle, the operator
will be switched off electrically.
Important: Ater emergency operation, bring the
handle back into home position, otherwise
the operator will remain switched off.

Pull on the cord with red knob, loop the taut cord tightly around the fixing screw
as shown in the detail below and secure with the wing nut. After employing the
quick release, it is important to secure the pull cord with slight slack with the
wing nut as shown in the detail below.
Important! Please observe the regulations governing
spring safety devices and cable safety
devices specific to the country in question.
Caution! The operator motor may only be disengaged with the door
closed. This must be carried out by specialist
personnel for maintenance purposes only.

Attention:
Only carry out work on the completely installed door and with the torsion spring tensioned.
The given dimension of 135 mm must be observed.
In the case of longer fixtures, screw housings
O
B and
O
C to the fixture using mounting plate
O
A . For doors with a wicket
door, >5600 mm, screw the housing without mounting plate
O
A directly onto the door leaf, the electronics circuit board on
the control unit side, the distributor on the opposite side.
Attention:
Remove the locking pin of the cable slack device or cable safety device on both sides.
Insert safety contact
O
D into the housing of the cable slack device or cable safety device and screw in place.
Attention:
The flat cable of the safety switches must be fed into the housing from below.
Loosen the outer PG nuts on both housings, push the PG nuts over the flat cable of the switches, insert the flat cable through
the moulded gasket and retighten the nuts.
If a closing edge safety device is included, cut out the floor seal as shown in figures 11.1 or 11.2. Push the optosensors
(transmitter = grey, receiver = black) into the profile, with the receiver on the control unit side and the transmitter on the
opposite side.
Allow the connecting cable to re-emerge through the pre-punched opening in the floor seal. Push connecting cable
O
G
through the upper chamber in the floor seal and allow to re-emerge through the pre-punched opening in the floor seal.
Loosen the central PG nuts, push them over the flat cable, insert through the moulded gasket and retighten the nuts. Now
push together the plugs on both sides in accordance with the printed symbols.
Attention:
Any PG connections not in use must be closed off with sealing washers
Close both housings with their covers.

If operator drives in neither direction:
- Check the voltage. Check the fuses in the mains isolator and the small fuses in the control box as well as
the mains plug.
- check wiring to limit switches and to motor unit.
- check the static current circuit, i.e. "Stop" button, wicket door contact, cable slack device.
Drive operates in "Close" direction without self-hold:
- The closing edge safety device (optosensor) is automatically tested for correct function prior to every
door closing cycle.
If during the course of this self-monitoring no test signal is given (light path interrupted, cable broken),
the controls will automatically switch over to the dead man's circuit for the next door closing cycle
("Close" without self-hold).
If self-hold is not available, check the following:
- Press-and-release operation for direction "CLOSE".
- optosensor not connected?
- wire broken or terminal fault on coiled cable.
- drive cuts out within 1 sec. of the door opening or closing (power limitation activated).
- check that door runs smoothly.
Commissioning
Industrial door operators must be wired, commissioned and checked at least once a year by a qualified specialist
(with written verification).
The closing edge safety device must be tested as follows:
Optosensor test:
Remove the optosensor or receiver from the door bottom edge seal.
Open and close the door.
The next door closing cycle must then be without self-hold.
Maintenance
The Dynamic operator is pratically maintenance-free. However, all moving parts of the door and operator should be
checked regularly.
Maintenance of the wicket door contact:
Check whether the magnetic contacts connected in series switch separately.
To do this, bridge one contact at a time and open the wicket door.
This should cut off the electric operator immediately.
