Read the sentences and point out numbers of those which deal with the topic “Work of an Adjustable Time Delay”.

1. All alarms can be delayed by an adjustable period ranging between 1 s and 60 s. 2. The diesel-driven generator supplying the distribution network is then synchronized to the shaft generator by the synchronizing unit. 3. If no diesel-driven unit is synchronized to the network after an adjustable time delay, the shaft generator breaker will trip and blackout will occur. 4. When the shaft generator is in service and no alarm operative, a shut-down signal will be applied to all diesel-driven generators. 5. These generators will be unloaded, and the circuit breakers will then trip the generators from the distribution network. 6. The time delay for tripping the shaft generator circuit breaker can be set at any value between 1 s and 60 s.
