6.3.2 Pipe filling
Overview
In the water supply systems, the rapid inrush of water into an empty pipe can cause hammer
effect and thus damage the pipe or the valve. With the pipe filling function enabled, the
converter fills the pipe slowly and smoothly after each power-up to avoid hammer effect to the
pipe. If the pipe filling is interrupted (for example, fault occurs), the function continues after the
converter is recovered. This function is used in horizontal, vertical, and mixed piping systems.
Precondition
Before enabling the pipe filling, make sure that p1143 = r29640.0 and p1144 = r29641.
