Status displays. For example, enter 0.070 for 7 cents
per KWH.
Saving vs —The basis for savings estimates. The
cost of VSD operation can be compared to Inlet
modulation, Load/Unload, or variable displacement
(spiral valve) control systems.
Reset Load Est. —This resets the "Recent Usage"
values to zero in the VSD Status calculations. This
functions similarly to a trip odometer in a car.
6.4.3 VSD CALIBRATION
Two additional calibration adjustments are provided
in VSD. These can be used to fine tune nominal
values used in VSD Status displays. Each is
adjustable from 0 to 200% of nominal.
Cap—for adjustment of delivery values. This may be
used for adjustment to actual conditions, or for
display in other units of measure.
KW—This may be used for adjustment to calibrated
meters under actual operating conditions.
6.4.4 VSD FACTORY SETUP
Factory adjustments are generally the same as
conventional packages, with a few additions.
Model —The features in this section apply only to
V120, V160, V200, V200S, V200TS and V320TS
models. These packages are designed specifically
for integrated drive control. This model selection will
affect the choices available in the VSD Setup group.
Capacity —This number will be adjusted, along with
maximum speed, whenever a change is made to the
setpoint pressure. Spiral Valve—This should be set
as appropriate for the package. The spiral valve will
be closed for highest efficiency at all moderate to
heavy demands. The valve will be opened for light
demands.
VSD —The descriptions in this section apply only to
packages with integrated drive controls operating in
serial communications with the Supervisor.
6.4.5 VSD SETUP
This group of adjustments sets up the parameters of
the drive for the construction of the compressor
package. These may be viewed at any time, but are
protected by the password in the Factory Setup
group.
VSD Auto-Set— This should be set to "Yes" for all
normal applications. This performs automatic
adjustment of several parameters based on
operating conditions and user adjustments.
Nominal HP —The nameplate horsepower of the
main drive motor.
Nominal Volts —The compressor package rated
nominal voltage
VSD Max Amps —The rated maximum current of the
drive
Motor FLA —The motor's rated full load amps at
nominal HP(I)
Motor SF —The motor's nameplate service factor
Motor V —The motor's rated voltage(I)
Motor Hz —the motor's nameplate frequency
Motor RPM —the motor's nameplate full-load speed
(I)Some package designs employ motors connected
for voltages lower (and FLA higher) than the nominal
voltage of the package, for improved performance.
6.5 STARTUP OF NEW
COMPRESSOR PACKAGE
1. Read and follow all safety warnings and cau-
tions in this manual.
2. At installation ensure:
• That the incoming power and ground wires
are properly connected to terminal blocks
in the electrical control box.
• Visually check all power and controls con-
nections to the drive to ensure that no dam-
age has occurred.
3. Check that moisture has not condensed
inside the variable speed drive.
4. Connect to the utility and switch the power
on. The Supervisor will establish communi-
cations and report errors if correct conditions
are not found. If replacing a drive, communi-
cation faults will be indicated for either
improper communication wiring or improper
application or communication software in the
drive.
5. To check rotation, quickly press first the Start
then the Stop key on the Super-
visor. Compressor rotation is factory set. If
the fan rotates incorrectly, disconnect power
and simply interchange two of the fan motor
leads at the fan starter.
