Display Configuration

The DISP submenu is used to configure the local display settings.
A list is shown in Table 79.
Test Display LEDs (TEST)
This is used to test the operation of the ComfortLink display.
Metric Display (METR)
This variable is used to change the display from English units to
metric units.
Language Selection (LANG)
This variable is used to change the language of the ComfortLink
display. At this time, only English is available.
Password Enable (PAS.E)
This variable enables or disables the use of a password. The pass-
word is used to restrict use of the control to change configurations.
Service Password (PASS)
This variable is the 4-digit numeric password that is required if
enabled.

VFD Configurations

There are two sub-menus under the Configuration menu, Config-

uration S.VFD and Configuration
tions are for units equipped with optional supply fan or exhaust
fan variable frequency drives (VFDs). These sub-menus contain
the configurations required for the supply fan and exhaust fan
VFDs. This section defines the configurations in these sub-menus.
See Tables 80 and 81. Further information on VFD configurations
can be found in Appendix D.
SUPPLY FAN VFD CONFIGURATION
The sub-menu that contains these configurations is located at the
local display under Configuration
VFD1 Nominal Motor Volts (N.VLT)
This configuration defines the nominal motor voltage. This val-
ue must equal the value on the motor rating plate. This value sets
the maximum drive output voltage supplied to the motor.
NOTE: The VFD cannot supply the motor with a greater voltage
than the voltage supplied to the input of the VFD. Power to the
VFD must be cycled in order for a change to this configuration to
take effect.
VFD1 Nominal Motor Amps (N.AMP)
This configuration defines the nominal motor current. This value
must equal the value defined in the Supply Fan Motor Limitations

Table 27 or 28. Power to the VFD must be cycled in order for a
change to this configuration to take effect.
VFD1 Nominal Motor Freq (N.FRQ)
This configuration defines the nominal motor frequency. This val-
ue must equal the value on the motor rating plate. This value sets
the frequency at which the output voltage equals the Nominal Mo-
tor Volts (N.VLT). Power to the VFD must be cycled in order for a
change to this configuration to take effect.
VFD1 Nominal Motor rpm (N.RPM)
This configuration defines the nominal motor speed. This value
must equal the value on the motor rating plate. Power to the VFD
must be cycled in order for a change to this configuration to take
effect.
VFD1 Nominal Motor HPwr (N.PWR)
This configuration defines the nominal motor power. This value
must equal the value on the motor rating plate. Power to the VFD
must be cycled in order for a change to this configuration to take
effect.
VFD1 Motor Direction (M.DIR)
This configuration sets the direction of motor rotation. Motor di-
rection change occurs immediately upon a change to this configu-
ration. Power to the VFD need NOT be cycled for a change to this
configuration to take effect.
VFD1 Acceleration Time (ACCL)
This configuration sets the acceleration time from zero to maxi-
mum output frequency. Power to the VFD must be cycled in order
for a change to this configuration to take effect.
VFD1 Deceleration Time (DECL)
This configuration sets the deceleration time from maximum out-
put frequency to zero. Power to the VFD must be cycled in order
for a change to this configuration to take effect.
VFD1 Switching Frequency (SW.FQ)
This configuration sets the switching frequency for the drive.
Power to the VFD must be cycled in order for a change to this
configuration to take effect.
VFD1 Type (TYPE)
This configuration sets the type of VFD communication. This
configuration should not be changed without first consulting a
Carrier service engineering representative.
