Certification CSA certification pending for use as process control equipment in an ordinary (nonhazardous) locationThis section explains the operation of the IMHSS03 Hydraulic
Servo Module. It gives an overview of the hydraulic servo (HSS)
module and related modules within a process control system
and explains the operation of key module circuitry.
CONTROL LOOP OPERATION
The HSS module, frequency counter (FCS) module and
multi-function processor (MFP) module form the controlling
segment of a closed loop control system. The MFP module
directs the control process. The HSS and FCS modules interface the process to the MFP module. Figure 2-1 shows a diagram of the turbine speed control loop and the control signals
to and from the process.
