Field/LED name
Description
Motor run (LED)
Indicates whether the digital output from the controls is commanding the motor to
RUN.
% Full Load Amps
Displays the motor current as a percentage of the Full Load Amps (FLA) value. For the
Variable Speed Drive, this is the data returned by the VSD Logic Board.
Motor current limit setpoint
Displays the current limit value in use. This value could come from a 0 mA to 20 mA, 4
mA to 20 mA, 0 VDC to 10 VDC, or 2 VDC to 10 VDC input in Analog Remote mode, PWM
signal in Digital Remote mode, SC-EQ communications interface in ISN (BAS) mode, or
a locally programmed value.
Pulldown demand time left
Displays the time remaining in the programmed pulldown period if the value is
nonzero.
Full load amps
Displays the Full Load Amps value as reported by the VSD.
VSD model
Displays the VSD model as reported by the VSD.
Water pump output (LED)
Indicates whether the relay controlling the water pump output is energized.
Precharge relay output (LED)
Indicates whether the relay controlling the precharge output is energized.
Trigger SCR output (LED)
Indicates whether the relay controlling the Trigger SCR Output is energized.
DC bus voltage
Displays the DC Bus voltage as reported by the VSD.
DC inverter link current
Displays the DC Inverter link current as reported by the VSD.
Internal ambient temperature
Displays the ambient temperature inside the VSD cabinet as reported by the VSD.
Converter heatsink temperature
Displays the heatsink temperature of the converter as reported by the VSD.
Heatsink temperature
Displays the baseplate temperatures of the 3 phases of the VSD inverter as reported
by the VSD.
Programmable
None
