Preface
The Frequency Counter Slave Module (IMFCS01) is a single
channel frequency input for the Multi-Function Processor
(MFP), Multi-Function Controller (MFC) and Hydraulic Servo
Slave Module (HSS). It interfaces a steam or gas turbine to the
MFP or MFC, providing them with accurate frequency count
and time period data. The MFP or MFC uses the frequency
count to calculate turbine speed and initiate speed control
through the HSS.
This manual provides the user with information and instruc-
tions for installation, operation and troubleshooting of the
FCS. Anyone involved with the installation and operation of the
frequency counter slave should carefully read and understand
this manual.
General information about the module and related equipment
is contained herein.
