Fig. 37 — Status Display III
The operator can adjust the display brightness by touching Status
and
to darken the display or to lighten it.
Indicator lights (LEDs) indicate whether the unit is on and if
there are any warning or alarm conditions:
• Green LED (On): Control section is working. The On LED is
activated when the VFD receives power from mains voltage,
a DC bus terminal, or an external 24 V supply. At the same
time, the back light is on.
• Yellow LED (Warning): Indicates a warning.
• Flashing Red LED (Alarm): Indicates an alarm.
The warning and/or alarm LEDs light up if certain threshold val -
ues are exceeded. A status message and alarm text also appear
on the control panel. See Fig. 38.
Fig. 38 — Indicator Lights
The menu keys below the display and indicator lights include
Status, Quick Menu, Main Menu, and Alarm Log. The Status
menu indicates the status of the frequency converter and/or the
motor. Three display modes are available (see Fig. 35-37). Use
the Status key for selecting mode of display or for changing back
to display mode from the Quick Menu Mode, the Main Menu
Mode, or the Alarm Log mode. The operator can also use the
Status key to toggle between single or double read-out mode.
The Quick Menu key allows quick set-up of the frequency con -
verter. The most common HVAC functions can be programmed
here. Menu options include:
• My Personal Menu
• Quick Set-up
• Function Set-up
• Changes Made
• Loggings
The Function Set-up option provides quick and easy access to all
parameters required for most HVAC applications. Among other
features it also includes parameters for selecting which variables
to display on the local control panel, digital preset speeds, scal -
ing of analog references, closed loop single-zone and multi-zone
applications, and specific functions related to fans, pumps and
compressors.
The Quick Menu parameters can be accessed immediately un -
less a password has been created via 0-60 Main Menu Password,
0-61 Access to Main Menu without Password, 0-65 Personal
Menu Password, or 0-66 Access to Personal Menu without Pass -
word. It is possible to switch directly between Quick Menu
mode and Main Menu mode.
The Main Menu key is used for programming all parameters.
These can be accessed immediately unless a password has been
created via 0-60 Main Menu Password, 0-61 Access to Main
Menu without Password, 0-65 Personal Menu Password, or 0-66
Access to Personal Menu without Password. For most HVAC
applications it is not necessary to access the Main Menu parame -
ters but instead use the Quick Menu. Quick Set-up and Function
Set-up provides the simplest and quickest access to the typical
required parameters.
It is possible to switch directly between Main Menu mode and
Quick Menu mode. The parameter shortcut can be carried out by
touching the Main Menu key for 3 seconds. The parameter
shortcut allows direct access to any parameter.
Touch Alarm Log to display a list of the 10 latest alarms (num -
bered A1-A10). To obtain additional details about an alarm,
touch the navigation keys to reach the alarm number and touch
OK. Information is displayed about the condition of the frequen -
cy converter before it enters the alarm mode. The Alarm Log key
also provides access to a Maintenance log.
At the middle part of the local control panel, the Back key re -
verts to the previous step or layer in the navigation structure. The
Cancel key cancels the last change or command as long as the
display has not changed. The Info Key displays information
about a command, parameter, or function in any display window,
providing detailed information when needed. The four arrow
keys are used among menu options by moving the cursor in the
direction indicated. Touch OK to select a parameter marked by
the cursor or to enable a parameter change.
Operation keys for local control are found at the bottom of the
control panel (see Fig. 34). Hand On enables control of the fre -
quency converter via the local control panel. Hand On also starts
the motor, and it is possible to enter the motor speed data by
means of the navigation keys. The key can be selected as [1] En -
able or [0] Disable via 0-40 Hand On Key on the local control
panel.
NOTE: External stop signals activated by means of control sig -
nals or a serial bus override a start command via the local control
panel.
The Off key stops the connected motor. If no external stop func -
tion is selected and Off key is inactive, the motor can only be
stopped by disconnecting the mains supply.
Auto On enables the frequency converter to be controlled via the
control terminals and/or serial communication. When a start sig -
