Berner GA 401, Installation, Operating And Maintenance Instructions

ENGLISH 

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!

4.1   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!
