SECTION 2 - OPTIVIEW OPERATION
Pre-Rotation Vane Position
Displays the pre-rotation vane position as a value be-
tween 0 and 100%.
Supply kVA
Displays the supply kilovolt-amps (kVA) measured by
the filter (harmonic filter installed only).
Total Power Factor
Displays the relationship between the input power and
the supply kVA (harmonic filter installed only).
Voltage Total Harmonic Distortion –
(L1, L2, L3)
Displays the Total Harmonic Distortion (THD) for
each of the voltage lines as calculated by the filter (har-
monic filter installed only).
Supply Current Total Demand Distortion –
(L1, L2, L3)
Displays the Total Dynamic Distortion (TDD) for each
of the supply current lines as calculated by the filter
(harmonic filter installed only).
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 current 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.
kWH Reset
Access Level Required: SERVICE
Allows the user to reset the cumulative kilowatt-hours
to zero (0). Service technicians refer to the OptiView
Control Center Retrofit Kit - Trane Service Manual
(Form 160.10-M1)
.
Filter Inhibit (Harmonic Filter installed only)
Access Level Required: SERVICE
Allows operator to enable or disable the filter logic
from activating, although the system will still commu-
nicate with the device. Access to this setting is only
available when chiller is stopped.
Change Setpoint
Access Level Required: VIEW
Allows user to enter login password to change motor
settings. This button is only present at the “View” ac-
cess level.
NAVIGATION
Home
Access Level Required: VIEW
Returns the display to the Home screen.
VSD Details
Access Level Required: VIEW
Advances to the sub-screen which provides more in-
formation about the VSD.
ACC Details
Access Level Required: SERVICE
Advances to the sub-screen which provides more in-
formation about the Adaptive Capacity Control (ACC).
Filter Details (Harmonic Filter installed only)
Access Level Required: VIEW
Advances to the sub-screen which provides more in-
formation about the harmonic filter.
