SECTION 9
• LSM-2020 (LOAD SHARE MODULE)
General Information
The LSM-2020 is a remote auxiliary device that interfaces to the DGC-2020 and provides analog outputs
to the power system in the form of analog bias signals to the voltage regulator and speed governor. When
the breaker is closed and Load Sharing is enabled, the LSM-2020 will share real power load
proportionally with the other generators on the Analog or Ethernet Load Share Lines.
Refer to Section 7, Setup, for instructions on setting up a DGC-2020 and LSM-2020 for a load sharing
and kW control application.
Features
LSM-2020s have the following features:
•
A Ramping Function to load and unload generators smoothly
•
Communications via Ethernet or CAN bus
•
Demand Start/Stop and Generator Sequencing
•
kW Load/var Control
•
kW Load/var Sharing via analog and Ethernet load share lines
