Functional Description; Turbine Operation; Water Level Regulation - Deif Multi-line 2 Description Of Options

GPC, PPU
Option O1 contains three main functions.
1. Water level control
2. Jet deflector control
3. Modified regulation
These functions can be used in a combination or separately.
Water level control requires a 4-20mA transducer.
The turbine can be controlled by the multi-line 2 in five different ways. This depends on the
mode selection on the unit. The table shows the running modes depending on the mode setting.

A further description of the general running modes can be found in the
Designer's Reference Handbook.
The water level regulation must be used if the regulation depends on the water level in the
reservoir which contains the water that drives the turbine.
Activate water level control
To activate the water level regulation, the mode input 1 must be activated and the menu 4131
must be adjusted to ON (see the table above).
Transducer setup
The 4-20mA transducer must be connected to terminals 126/127 (see the I/O list above). The
setup is done in the system setup as well as in the input setup.
