SECTION 2 - OPTIVIEW OPERATION
Supply Contactor (LED)
Illuminates when the output to the supply contactor is
energized.
Precharge Contactor (LED)
Illuminates when the output to the precharge contactor
is energized.
Phase Rotation
Displays the phase rotation detected by the harmonic
filter (A, B, C or C, B, A)
Total Supply kVA
Displays the total supply kilovolt-amps (kVA) mea-
sured by the harmonic filter.
Baseplate Temperature
Displays the temperature of the harmonic filter base-
plate.
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 Distor-
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: OPERATOR
Allows the maximum allowed motor current (as a
percentage of FLA) to be adjusted. When the motor
current reaches this value, the pre-rotation vanes will
not open further. If the motor current rises above this
value, the pre-rotation vanes will close to reduce cur-
rent to this setpoint. This value is adjustable from 30 to
100%, with 100% as the default setting.
Pulldown Demand Limit
Access Level Required: OPERATOR
This setpoint limits the motor current (programmed as
a percentage of FLA) during the specified pulldown
demand time. This value will override the motor cur-
rent limit value during this time period. This function is
used to provide energy savings following chiller start-
up and is adjustable from 30 to 100%, with 100% as
the default setting.
Pulldown Demand Time
Access Level Required: OPERATOR
This setpoint programs the period of time the pulldown
demand limit will be in effect after the chiller starts.
The pulldown demand time is adjustable from 0 to 255
minutes, with 0 minutes as the default.
