2. Description of option
This document contains information about the water turbine control contained in option O1.
Option O1
Function ANSI no.
3 x 4...20mA inputs with alarms/shutdowns 77
1 x 4...20mA inputs with for indication 77
Option O1 can be combined with option M1 or M2.
Terminal description
Slot #8, 4-20mA input PCB
Term. Function Description
126 Input 5 common Common
127 Analogue input 5+ 4-20mA in for water level control
128 Input 6 common Common
129 Analogue input 6+ 4-20mA in
130 Input 7 common Common
131 Analogue input 7+ 4-20mA in
132 Input 8 common Common
133 Analogue input 8+ 4-20mA in
The 4-20mA input no. 5 must be used for water level input. The 4-20mA inputs
no. 6, 7 and 8 can only be used as alarm inputs.
This option is only available for the GPC and the PPU.
If the generator is an asynchronous generator then option M1 or M2 must be
used at the same time as option O1!
