Table 76 — Switch Logic Configuration
Evacuation Switch — Off (EVC.L)
The evacuation input is set for normally open when off. If a
field-supplied evacuation input is used that is normally closed,
change this variable to closed.
Smoke Purge — Off (PRG.L)
The smoke purge input is set for normally open when off. If a
field-supplied smoke purge input is used that is normally
closed, change this variable to closed.
Dehumidify Switch — Off (DH.LG)
The dehumidify input is set for normally open when off. If a
field-supplied dehumidify input is used that is normally closed,
change this variable to closed.
Display Configuration
The DISP submenu is used to configure the local display set-
tings. A list is shown in Table 77.
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 Com-
fortLink 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, Con-
figuration
S.VFD and Configuration
E.VFD. These con-
figurations 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 78 and 79. 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
S.VFD.
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 val-
ue must equal the value defined in the Supply Fan Motor Lim-
itations Table 26 or 27. Power to the VFD must be cycled in or-
der for a change to this configuration to take effect.
VFD1 Nominal Motor Freq (N.FRQ)
This configuration defines the nominal motor frequency. This
value must equal the value on the motor rating plate. This val-
ue sets the frequency at which the output voltage equals the
Nominal Motor Volts (N.VLT). Power to the VFD must be cy-
cled 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 val-
ue 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 val-
ue 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
direction change occurs immediately upon a change to this
configuration. 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 max-
imum 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
output 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.
