6.3 INSTALLATION
This variable speed AC drive has been properly
mounted, adjusted, and tested prior to shipment of
the compressor package. Inspect the unit to ensure it
was not damaged during shipment. The package
provides a terminal block for connection of
threephase power and ground. Refer to the package
wiring diagram for specific connection information. All
internal wiring to the drive and motors has been
provided by the factory, in accordance with the
drive's requirements. Do not alter factory wiring. To
ensure proper wiring to the package, use the
following guidelines:
• Use heat-resistant copper cables only,
+75°C or higher.
• The minimum input line cable and line
fuses must be sized in accordance with the
rated input current of the unit. See
Table 6-
1 .
• Consistent with UL listing requirements, for
maximum protection of the variable speed
drive, use UL recognized fuses, type RK5.
• Suitable for circuits delivering fault currents
up to 100,000A.
6.4 SUPERVISOR DISPLAY AND
MENUS
Refer to Section 2 for a general description of the
Supervisor and its displays and adjustments. This
section addresses special functions applicable to
VSD packages.
6.4.1 VSD STATUS
This group of displays shows the performance of the
variable speed compressor package. The following
may be used for evaluation of system performance.
The first four lines indicate real-time conditions:
Capacity —Delivery in CFM.
Capacity % —Percent of full package capacity.
Power —Total package power in KW.
Power % —Percent of power at full capacity. The
next eight lines indicate recent longer-term
performance. See
Section 6.4.2 for reset procedure.
Capacity—Average delivery in CFM.
Capacity % —Average percent of full package
capacity.
Power —Average total package power in KW.
Power %— Average percent of power at full capacity.
KCF —Running total of air delivered in thousands of
cubic feet.
KWH —Running total of energy used in
kilowatthours.
Cost —Running total of cost of operation.
Savings —Estimated savings compared to other
control methods.
The next eight lines indicate long-term performance
during the entire life of the compressor.
Capacity —Average delivery in CFM.
Capacity % —Average percent of full package
capacity.
Power —Average total package power in KW.
Power % —Average percent of power at full capacity.
KCF —Running total of air delivered in thousands of
cubic feet. KWH—Running total of energy used in
kilowatthours.
Cost —Running total of cost of operation.
Savings —Estimated savings compared to other
control methods.
The last five lines indicate real-time control system
parameters for service evaluation.
P2 —System pressure.
Motor RPM —Motor speed.
Frequency —Output frequency of the drive in Hertz.
Drive Temp —Internal temperature of the drive.
Motor Prot —Estimated percentage of motor
temperature rise.
6.4.2 VSD CONTROL PARAMETERS
The following adjustments apply specifically to VSD
packages.
Setpoint —The targeted pressure for the variable
speed controls. This is normally adjusted near the
bottom of the load/unload band above. The speed
will be adjusted to maintain this pressure. Most
packages will allow adjustment of this over a wide
range, to allow tailoring to the needs of the
application. Adjustments will be automatically made
to the maximum speed to operate the motor at its full
capacity at any pressure.
Cost/KWH —The cost per kilowatt-hour of energy is
entered here, for use in cost estimates in the VSD
