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 autoreclose 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 pickup 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:
• Str 3 delay shot 1
