Page 8: Functional Description
Water level control requires a 4-20mA transducer. Turbine operation 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. - Page 9 This can be adjusted from the USW or from the display. The 4mA value can be adjusted negative. This is to be able to stop the regulation (see the description of ‘Water level regulation’ on page 10). DEIF A/S Page 9 of 19...

Page 10: Regulation Principle
Regulation principle Principle When the regulation is started, the multi-line 2 will regulate the power according to the water level and the fixed power set point. The below drawing illustrates how the regulation works: 1. - Page 11 (The purpose of this is partly to avoid the generator to go into reverse power and partly to keep the turbine in the economic operating range.) The operating range of the turbine can be reduced in the high end by decreasing the P (menu 4041) to a lower value. DEIF A/S Page 11 of 19...

The relay used for the jet deflector is the relay 1. (Terminal 5, 6, 7 - see extract from I/O list below). Term. Function Technical Description data Relay 1 Configurable/jet deflector operation Com. 250V AC / 8A DEIF A/S Page 12 of 19... - Page 13 When the deflector must open, relay 1 will change position to 5/6, thus disconnecting the current flow through 6/7. The purpose of using the status relay is to open the deflector whenever the multi-line 2 is without power or when the watch dog of the device detects a fault.

20mA. At this point, cascade #2 will take over and increase its output until 20mA, and so on. When the turbine is stopped the sequence is reversed. The output sequence looks like this in a situation where all cascades open: DEIF A/S Page 14 of 19... -

The turbine start function can be used in connection with relay outputs only. This timer represents the time where the speed UP signal is active if no speed is detected during start-up of the turbine. (Running detection is the frequency measurement or pick-up tacho input).
