摘要：One group of optical transmitting set (18), for sending light pulse, one for receiving the optical receiver (10) of light, the output power of an optical sender (18) for transmitter (18), the output power for optical sender (18). For receiving the erkennungsschaltung (12) of light pulse, there is the generator for a, intensity changes with optical pulse intensity is received, and has the low intensive display (27) for receiving light. The output power of optical sender (18) is allowed to be automatically adjusted to pollution or unreasonable A, first comparator (19) has the signal of predetermined target value and compares, trigger switch operation $ A-signalling means (23,2). 3 ', when sender unit (23,23 ') connection being connect with connecting component (19), the signal wire of switch operation depending on first comparator (19) increases or decreases, and if disconnecting, signal wire is remained unchanged, $ parator (20). Schalt. is generated between sender unit (23,23 ') and first comparator (19) with a on the low-intensity direction of the reception light pulse of different threshold value comparisons and by the $ a- that first comparator (19) generate, first part (19) expressionete schaltstufe(21).
