4.11 Setting variable speed module parameters
Variable speed module (VSM) is an optional accessory that is connected to burner
control through LSB bus. Electrical connections (sensors, mA/V messages etc.) to
burner control are made according to electrical connections.
VSM module provides 0/4-20mA or 0-10V setpoint output for frequency converter. In
addition there is a changeover contact in the burner to get frequency converter started.
VSM basic settings are adjusted with DIP switches and parameter settings with PC
application (LSB remote).
DIP switches are located on the module cover. Following tables show factory settings
