But if the internal automatic reclose function is controlled by the pickup (only possible for 3-pole tripping: 110
Trip mode = 3pole only), the phase-selective
pickup signals of the external protection must be connected
if distinction shall be made between different types of fault. The general trip command then suffices for trip-
ping (No. 2746). Figure 2-12 shows a connection example.
