3.8.4 Confirmation of correct learning/deletion

The output which is toggling every second while in teach-in mode (see above) will stay

switched high for 4 seconds to signal that a transmitter has been learned. In case a trans-

mitter ID has been deleted it will stay 4 seconds low.

3.8.5 Learning of further transmitters

After confirmation, the receiver changes again to readiness for learning. Further transmit-

ters can be learned immediately. If available the next receiver channel can be entered by

connecting the LRN pin to GND longer than t = 0.5 seconds. A maximum of 30 radio

transmitters can be learned (further attempts will be ignored; instead of learning confirma-

tion, operating mode is entered). Each rocker of a radio transmitter is counted as one

transmitter.

3.8.6 Selecting the next channel

By fresh contacting of the LRN pin to GND the next remaining channel is selected. In one-

channel mode or after the last channel, the operating mode is entered again.

3.8.7 Leaving learning mode

LRN mode is left in either one of the following events:

 Output of last available channel is toggling and a fresh contacting of the LRN pin to GND

for 0.5 seconds is performed

 No ID has been added/deleted during the last 30 seconds.

 Memory was full and another ID was sent to be learnt

3.8.8 Deleting a transmitter

Deletion of one specific transmitter: Use the same procedure as learning the associated

transmitter.

As transmitter delete confirmation, the corresponding function outputs remain in inactive

state for 4 seconds while LMI keeps active. After that, a wrongly deleted transmitter can be

learned again immediately.

In order to delete a PTM transmitter the same rocker as during learn has to be

operated. If several rockers of a PTM transmitter have been learned, all have to be

deleted separately.

Deletion of all learned transmitters: Connect the CLR pin longer than 2 seconds to GND

All learned transmitters on all channels are deleted at the same time. After this, the re-

ceiver enters Learning Mode.

Please note that in modes 2, 3, and 4 only RPS or HRC telegrams can be learned!
