Note

If the force is insufficient for the learning cycle, it can be

increased as follows:

By pressing the black button for at least 3 sec. during learning

cycle, the max. admissible shut down speed will be switched

from 50% to 40%.

The successful switching is indicated by the luminosity (approx.

1 sec.) of the halogen lamp. Repeat this procedure for a new

learning cycle.

If the force or speed is insufficient for the learning cycle,

the force/speed can be increased from 30 % to 50 % via

the DIL 4. Start the learning procedure once again.

For sectional doors, we recommend setting the DIL 4

to "OFF" before starting the learning phase.

3.2.3 Setting the maximum forces

The required forces for opening and closing the door,

which were learned and stored during the learning

phase, are updated also during the subsequent travel

cycles.

That's why, if the running action of the door gets

increasingly sluggish (e.g. spring tension slackens), it is

important for safety reasons that these values do not

infinitely reset themselves, as any necessary manual

operation of the door could otherwise present a possible

safety risk (e.g. door could crash to the floor).

The actually required forces are firmly memorised on the

microprocessor during memorisation – safe from errors

and power failure. The power tolerance at delivery is

suitable for the operation of standard doors. If the

memorised power is exceeded during closure, an

obstacle release of 300 mm in “OPEN” direction will be

effected. If the power values are exceeded during

opening, a short reverse will be effected, i.e. the operator

moves a short way to the closure direction.

Note

The obstacle release in “CLOSE” direction can be switched

from 300 mm reverse to complete opening. Switching is

effected if the black button is pressed for at least 3 sec. during

the first force learning caycle in opening direction (first cycle

after memorisation). The successful switching is indicated by

the luminosity of the halogen lamp. If the function “automatic

closing” is selected, the door generally opens completely after

having met an obstacle. For a new learning process this

procedure has to be repeated.

3.2.4 Setting the door speed

The door speed of the operator can be changed if

necessary. To set the speed a potentiometer is available,

which is accessible after opening the vision panel and is

marked with P1 (see figure 20.2).

Herewith the speed is augmented through turning

clockwise and reduced anticlockwise. The speed is

factory set on max. (P1 on right stop).

Note

After changing the door speed the operator has to be newly

programmed!

4 Installation: garage door operator and accessories

4.1 Notes on work involving electrics/electronics

4.2 Connecting the radio receiver

The radio receiver is plugged in as follows:

Plug connection (see figure 8). The receiver is plugged

into the corresponding connector plug-in on the

operator head. Check that the plug has properly engaged.

With regard to programming hand transmitter buttons

into the receiver, please refer to the corresponding

instructions.

4.3 Connecting an external radio receiver *

The radio receiver is plugged in as follows:

The plug of the receiver is plugged into the corresponding

4-pole corrector jack (see figure 8).

- the green ledge (GN) to the clamp 20 (0 V)

- the white ledge (WH) to the clamp 21 (channel 1)

- the yellow ledge (YE) to the clamp 23 (channel 2)

- the brown ledge (BN) to the clamp 5 (+24 V)

Note

The antenna flex of the radio receiver should not touch metal

objects (nails etc.). The best sending position has to be found by

trying. GSM 900- mobile phones can influence the use of the

radio system when used at the same time.

In case of a 2-channel receiver the first channel always takes

the function of control by impulsion (opening of the door). The

second channel can be used for partial opening or for closing.

(see chapter 5.1 and 5.2).

4.4 Electrical connection / Connection clips (see figure 7)

To connect additional components, the view panel must

be removed. The terminals to which the additional

components, such as floating internal and external button,

OFF button or wicket door contact as well as photocells,

are connected, carry a safe low voltage of max. 30 V DC

only. All the connecting terminals are designed for multiple

assignment, however, for max.1x1.5mm2 (see fig. 7.2).

Before connecting, always pull out the mains plug first!

ATTENTION! The following points apply

to all work involving electrics/electronics:

- Electrical connections may only be made by a

qualified electrician!

- On-site electrical installation must comply with the

relevant safety regulations (230/240 V AC, 50/60 Hz)!

- Before working on the operator, always unplug from

the mains!

- External voltage at any of the controls connecting

terminals will completely destroy the electronics!

- To avoid malfunctions, ensure that the control

cables of the operator (24 V DC) are laid in an

installation system separate to other supply lines

(230 V AC)!

* Accessory is not included in delivery!
