Field name Description
Voltage Total Harmonic
Distortion L1, L2, L3
The total harmonic distortion (THD) for each of the voltage lines as calculated by the VSD
Input Current Total Demand
Distortion L1, L2, L3
The total dynamic distortion (TDD) for each of the supply current lines as calculated by the
VSD.
Input Job Full Load Amps The job input FLA limit within a range limited from 10% to 100% of the drive nominal input
current at nominal line voltage

Table 53: Programmable fields
Name Access Description
Local Input Current Limit Operator
Specifies 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 Operator
Specifies the current limit value as a percentage of FLA to which the chiller
is limited during the specified pulldown limit time. This value overrides the
input current limit value during this time period. Provides energy savings
following chiller start-up. Pulldown demand limit is ignored in BAS (ISN)
control source because the BAS system algorithmically resets current limit as
required in that operating mode.
Pulldown Demand Time Operator
Set a period of time for which the pulldown demand limit to be in effect after
the chiller starts.
