YORK INTERNATIONAL
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 speciÞ 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.
