YORK INTERNATIONAL
Voltage Peak ( N-L1, N-L2, N-L3 )
Displays the 3-phase peak voltages as measured 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 Distortion
(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
: OPERATOR
Allows the user to specify the maximum allowed mo-
tor current (as a percentage of FLA). When the motor
current 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
: OPERATOR
Allows the user to specify the current limit value (as a
percentage of FLA) to which the chiller will be limited
during the specified pulldown limit time. This value will
override the Motor Current Limit value during this time
period. This function is used to provide energy savings
following chiller start-up.
Pulldown Demand Time
Access Level Required
: OPERATOR
Allows the user to set a period of time for which the
pulldown demand limit will be in effect after the chiller
starts.
