Garage door opener, function - GF68.05-P-0001RF
Model 205, 253 with code 232 (Garage door opener)
Function requirements, general
- Circuit 15R ON
The circuit 15R status is sent by the electronic ignition lock control unit (N73) over the interior CAN (CAN B) to the front SAM control unit (N10/6).
Garage door opener, general
The garage door opener (A67n2) is a remote control capable of learning with which various receivers for the opening and locking systems for doors or gates can be activated. The garage door opener is integrated into the inside rearview mirror (A67). The garage door opener is connected to the front SAM control unit via the roof LIN (LIN B13). The garage door opener radio signal has a range of approx. 85% of the original hand transmitter. Frequencies between 284 and 390 MHz are available for the radio signal.
User guidance (single-hand operation) consists of a multicolored indicator lamp in the garage door opener (A67e4) (green, yellow and red).
The garage door opener function comprises the following partial functions:
- Function sequence, transmit radio signal
- Function sequence, program the memories
- Function sequence, erase the memories
- Function sequence for resetting to as-delivered state
- Function sequence for protection against misuse
Function sequence, transmit radio signal
When one of the following buttons is pressed, a radio signal assigned to this memory is transmitted:
- Button 1 garage door opener (A67s1)
- Button 2 garage door opener (A67s2)
- Button 3 garage door opener (A67s3)
The function is confirmed by the garage door opener indicator lamp (green).
Function sequence, program the memories
Keep desired garage door opener button pressed for at least t = 10 s. As a result the garage door opener changes into learning mode which is displayed by the flashing of the garage door opener (yellow) at a frequency of f = 1 Hz. Then press original hand transmitter close to the garage opener transmitter unit with transmitter function activated for up to t = 90 s (s = 3 to 20 cm). The transmission frequency of the original hand transmitter is now programmed. In the process the garage door opener transmitter unit searches for the suitable frequency among the possible transmission frequencies.
Successful termination of the teach-in procedure is indicated by the garage door opener indicator lamp illuminating green (fixed code learned in) or flashing green (variable code with f = 5.6 Hz learned in). An unsuccessful attempt is indicated by the garage door opener indicator lamp illuminating red.
The garage door opener is compatible with approx. 85% of the garage door opening systems offered on the primary turnover markets. If the original hand transmitter is not compatible with the garage door opener, a universal receiver ("Fix Kit Receiver") which reacts to the in-plant programming of the garage door opener can be installed in the garage.
Function sequence, erase the memories
To erase the memories, press the two outer garage door opener buttons (1 and 3) simultaneously for a period of a least t = 10 s. The garage door opener indicator lamp flashes green for t = 10 s. Release garage door opener buttons during flashing phase. The existing data of the memory locations is erased.
The garage door opener goes to the learn-in mode when one of the three garage door opener buttons is pressed again. If no programming is performed in learning mode during a period of t = 100 s, the garage door opener switches off automatically to protect the on-board electrical system.
Function sequence for resetting to as-delivered state
To reset press the two garage door opener outer buttons (buttons 1 and 3) simultaneously for at least t = 30 s.
Basic setting: "Chamberlain"-algorithm (f = 310 MHz).
Function sequence for protection against misuse
The front SAM control unit sends a security code to the garage door opener via the roof LIN with each function activation. If the safety code transmitted does not coincide with the stored safety code, the channels learned in are erased. However, the national coding is maintained.
