In a blinking of the alarm system the fused lamp is not noticeable by a rhythm of work of indexes of turns too. About replacement of lamps see in the head Osveshcheniye.
- If at the included indexes of turn or the alarm system lamps burn constantly, then the relay breaker is faulty.
- If indexes of turns blink in slowed down, in the accelerated rhythm and all plug connections, including the wire of lamps connected to weight, as it should be – it is necessary to replace the relay in the switch of the alarm system.
- If only the alarm system without indexes of turns or on the contrary works, then tension through the corresponding safety lock does not move (see the table in the head the Electrotechnical equipment) or the switch of the alarm system is faulty (about dismantle see the head Instrumenty and devices).
