Output Current (RMS) - Phase A, B, C
Displays the RMS current measured to the motor, per
phase.
VGD Position
Displays the variable geometry diffuser position as a
value between 0 and 100%.
Input kVA
Displays the supply kVA measured by the VSD.
Input Power Factor
Displays the relationship between the Input Power and
the Supply kVA.
Rated Motor Voltage
Displays the motor voltage rating, based on configura-
tion.
Maximum Motor Current
Displays the maximum motor current, based on con-
figuration.
Motor % Full Load Amps
Displays the percentage of maximum motor current
presently delivered, based on highest phase.
Voltage Total Harmonic Distortion - (L1, L2, L3)
Displays the Total Harmonic Distortion (THD) for
each of the voltage lines as calculated by the VSD.
Input Current Total Demand Distortion -
(L1, L2, L3)
Displays the Total Dynamic Distortion (TDD) for each
of the supply current lines as calculated by the VSD.
Input Job Full Load Amps
Shows the job input full load amp limit within a range
limited from 10% to 100% of the VSD nominal input
current at nominal line voltage.
PROGRAMMABLE
Local Input Current Limit
Access Level Required: OPERATOR
Allows the user to specify the maximum allowed input
current (as a percentage of job FLA). When the input
current reaches this value, the input current override
takes effect.
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 input Current Limit value during this
time period. This function is used to provide energy
savings following chiller start-up. Pulldown demand
limit is ignored in BAS (ISN) control source because
the BAS system is expected to use its algorithms to
reset current limit as required in that operating mode.
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.
