Jet Deflector - Deif Multi-line 2 Description Of Options

GPC, PPU
In principle, the jet deflector is a 3-way valve intended to bypass the water flow in case there is a
generator shutdown.
Principle
Normally, the jet deflector is 'closed' (water flow led to the turbine) and held closed by a holding
magnet. In case of shutdown, the jet deflector magnet is deactivated, and the jet deflector
immediately changes to 'open' (water bypass) position.
The principle looks like this (jet deflector shown in 'closed' position):
Closed position
Water inlet
Open position
If the jet deflector is moved to the 'open' position, it must be set back to 'closed'
position manually.
Use the jet deflector feedback to indicate when the deflector is closed.
Relay selection
The relay used for the jet deflector is the relay 1. (Terminal 5, 6, 7 - see extract from I/O list
below).
