[Quick Menu]
allows quick set-up of the Adjustable frequency drive. The
®
most common VLT HVAC Drive functions can be
programmed here.
The [Quick Menu] consists of
- My Personal Menu
- Quick Set-up
- Function Set-up
- Changes Made
- Loggings
The Function Set-up provides quick and easy access to all
parameters required for the majority of VLT
applications including most VAV and CAV supply and
return fans, cooling tower fans, primary, secondary and
condenser water pumps and other pump, fan and
compressor applications. Among other features, it also
includes parameters for selecting which variables to display
on the LCP, digital preset speeds, scaling 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
unless a password has been created via 0-60 Main Menu
Password, 0-61 Access to Main Menu w/o Password,
0-65 Personal Menu Password or 0-66 Access to Personal
Menu w/o Password.
It is possible to switch directly between Quick Menu mode
and Main Menu mode.
[Main Menu]
is used for programming all parameters. The Main Menu
parameters can be accessed immediately unless a
password has been created via 0-60 Main Menu Password,
0-61 Access to Main Menu w/o Password, 0-65 Personal Menu
Password or 0-66 Access to Personal Menu w/o Password. For
®
the majority of VLT HVAC Drive applications, it is not
necessary to access the Main Menu parameters but instead
the Quick Menu, Quick Set-up and Function Set-up provide
the simplest and quickest access to parameters that are
typically required.
It is possible to switch directly between Main Menu mode
and Quick Menu mode.
Parameter shortcut can be carried out by pressing down
the [Main Menu] key for three seconds. The parameter
shortcut allows direct access to any parameter.
