Figure 375: Schematic diagram of delayed initiation input signals
In total, the AR function contains six separate initiation lines used for the initiation
or blocking of the auto-reclose shots. These lines are divided into two types of
channels. In three of these channels, the signal to the AR function can be delayed,
whereas the other three channels do not have any delaying capability.
Each channel that is capable of delaying a start signal has four time delays. The
time delay is selected based on the shot pointer in the AR function. For the first
reclose attempt, the first time delay is selected; for the second attempt, the second
time delay and so on. For the fourth and fifth attempts, the time delays are the same.
Time delay settings for the DEL_INIT_2 signal are as follows:
• Str 2 delay shot 1
• Str 2 delay shot 2
• Str 2 delay shot 3
• Str 2 delay shot 4
Time delay settings for the DEL_INIT_3 signal are as follows:
