Functional Description
Analog Inputs
The analog inputs can be configured to accept voltage or current. These inputs can be used for var, PF,
or kW control. The inputs are configured by using the Settings Explorer in BESTCOMSPlus
® to open the
Programmable Input, LSM Input screen. To set the LSM Analog Input as the control source, use the
Settings Explorer in BESTCOMSPlus
® to open the Bias Control Settings screens.
Analog Outputs
There are three analog outputs: AVR control, GOV control, and Load Share Line. Each output is
described in the following paragraphs.
Output for Voltage Regulator Control
The AVR output provides remote control of the generator voltage setpoint.
Output for Governor Control
The GOV output provides remote control of the generator speed setpoint.
Load Share Line Output
The generator uses the measured LS (Load Share Line) output to calculate per unitized average load
level, and uses that as the set point for its kW controller.
Generator Sequencing
Machines can be added or removed from the power system based on load demand. The following criteria
should be considered before adding or removing a machine:
•
Machine Priority
•
Engine Run Time
•
Machine Size
•
kW% of the load/demand
•
Out of Service machines
Communications
The LSM-2020 communication ports include CAN terminals and an Ethernet port.
CAN bus
A Control Area Network (CAN) is a standard interface that enables communication between the LSM-
2020 and the DGC-2020.
