Chapter 4.
Description of Operation
This chapter provides an overview of the features and operation of the 2301E-ST Load Sharing and
Speed Control.
The 2301E-ST Load Sharing and Speed Control uses a 32 bit microprocessor for all control functions. All
control adjustments are made with an external computer that communicates with the control via a serial
RS-232 port. The external computer can be disconnected from the control during normal operation, to
provide security against tampering.
When power is applied, the 2301E-ST performs internal memory tests to ‘boot-up’ the processor. This
takes approximately 30 seconds to complete. The CPU Status LED between terminals 30 and 31 remains
on during this boot-up. The control will remain in I/O lock and will not provide control to the prime mover
until the boot-up is complete. For systems requiring fast start functions, it is necessary to continuously
power the 2301E-ST.
DO NOT attempt to start the prime mover while the CPU Status LED
is ON.
DO NOT apply power to the control at this time. Applying power
before a control is completely connected may damage the control.
The 2301E-ST’s normal operating architecture is divided into two sections: The Service Mode and the
Configuration Mode. The Configuration Mode is used to configure the 2301E-ST for the specific
application and to set all operating parameters (see Chapter 5). The Service Mode is the normal turbine
operation mode and is used to view operating parameters and run the turbine.
The 2301E-ST is controllable from the Discrete Inputs or Modbus commands. The following processes
are explained by using the Discrete Inputs. These Discrete Inputs currently used here exist in the
commands (Boolean Writes) of Modbus. They can be operated similarly through the Modbus
communication.
