Heatsink Temperature
(Labeled “Baseplate Temperatures” on VSD with
part number 371-03789-xxx {503HP 60Hz; 419HP
50Hz}).
Displays the temperature of the Harmonic Fil ter Heat-
sink.
Voltage Peak (N-L1, N-L2, N-L3)
Displays the 3-phase peak voltages as mea sured by the
Harmonic Filter (Neutral to Line).
RMS Voltage (L1-L2, L2-L3, L3-L1)
Displays the 3-phase RMS Voltages across each line.
Voltage Total Harmonic Distortion (L1, L2, L3)
Displays the 3-phase voltage Total Harmonic Dis tor tion
(THD) measurements.
RMS Filter Current (L1, L2, L3)
Displays the 3-phase Filter current values as measured
by the Harmonic Filter.
Supply Current Total Demand Distortion
(L1, L2, L3)
Displays the 3-phase Current Total Demand Distortion
(TDD) measurements.
RMS Supply Current (L1, L2, L3)
Displays the 3-phase RMS Voltages across each line.
PROGRAMMABLE
Local Motor Current Limit
Access Level Required
: OP ER A TOR
Allows the user to specify the maximum al lowed mo-
tor current (as a percentage of FLA). When the motor
cur rent reaches this value, the pre-rotation vanes will
not be permitted to open further. If the motor current
rises above this value, the pre-rotation vanes will close
to reduce the current to this value.
Pulldown Demand Limit
Access Level Required
: OP ER A TOR
Allows the user to specify the current limit val ue (as a
percentage of FLA) to which the chiller will be limited
during the speci
Þ
ed pulldown limit time. This value will
override the Motor Current Limit value during this time
period. This function is used to provide energy sav ings
following chiller start-up.
Pulldown Demand Time
Access Level Required
: OP ER A TOR
Allows the user to set a period of time for which the
pulldown demand limit will be in effect after the chill er
starts.
