Vfd Display Navigation - Carrier 09FC020 Installation, Start-Up And Maintenance Instructions

VFD DISPLAY NAVIGATION

IMPORTANT: The VFDs are configured through the Car-
rier Controller controls, and parameters should not be
changed manually. This section is included for information
and troubleshooting purposes only.
NOTE: The following instructions apply to Danfoss VLT VFD.
See Table 11 for voltage specific VFD parameters.
The VFD can be operated in 2 ways:
• Graphical Local Control Panel (GLCP)
• RS-485 serial communication for PC connection
Graphical Local Control Panel
The LCD display is divided into 4 functional groups:
1. Graphical display with Status lines
2. Menu keys and indicator lights (LEDs) — selecting mode,
changing parameters and switching between display
functions
3. Navigation keys and indicator lights (LEDs)
4. Operation keys and indicator lights (LEDs)
See Fig. 34. The display is backlit with a total of 6 alpha-numer-
ic lines. All data is displayed on the GLCP, which can show up
to 5 operating variables while in Status mode.
The display lines (see items a-c in Fig. 34) function as follows:
a. The status line at the top of the display shows VFD
status when in [Status] mode or up to 2 variables
when not in [Status] mode, or in case of an alarm or
warning (alert).
b. The operator data line in the middle section shows up
to 5 variables with their related units, regardless of
status. In the case of an alarm or warning, the warning
is shown instead of the variables.
c. The status line in the bottom section always shows the
state of the VFD in Status mode.
The operator can toggle among 3 status read-out screens by
touching the Status key. Several values or measurements can be
linked to each of the displayed operating variables. The values/
measurements to be displayed can be defined via parameter 0-20
Display Line 1.1 Small, 0-21 Display Line 1.2 Small, 0-22 Dis-
play Line 1.3 Small, 0-23 Display Line 2 Large and 0-24 Dis-
play Line 3 Large. The settings are accessed by selecting
QUICK MENU  Q3 Function Setups  Q3-1 General Set-
tings  Q3-13 Display Settings. Each value/measurement read-
out parameter selected in 0-20 Display Line 1.1 Small to 0-24
Display Line 3 Large has its own scale and number of digits after
a possible decimal point. Larger numeric values are displayed
with fewer digits after the decimal point. For example, a current
readout might be 5.25 A,15.2 A, or 105 A.
Status Display I is standard after start-up or initialization. Touch
[INFO] to obtain information about the value/measurement
linked to the displayed operating variables 1.1, 1.2, 1.3, 2, and
3). See the operating variables shown in the display in Fig. 35.
Variables 1.1, 1.2, and 1.3 are shown in small size. Variables 2
and 3 are shown in medium size.
