Notes
• If, during normal operation, the REA-R.03/1 receives either a very weak control
telegram from REA23.03RF or no control telegram for longer than 25 minutes,
LED_1 starts to flash in red.
If the control telegram is still understood correctly, the receiver continues with nor-
mal operation. If the control telegram is no longer understandable, the relay re-
mains in the last switching position.
As soon as the REA-R.03/1 does receive a correct control telegram from the
REA23.03RF again, the receiver continues with normal operation
• In case of error, REA-R.03/1 switches off the relay approximately 60 minutes after
receipt of the last correct control telegram. The controlled device is also switched
off and LED_1 flashes in red.
As soon as the REA-R.03/1 does receive a correct control telegram from
REA23.03RF again, the receiver continues with normal operation
• In the event of a power failure at the REA-R.03/1, the relay is de-energized.
