Control unit LCP
The front of the VLT AFD features a control panel -LCP
(Local Control Panel). This is a complete inter-face for
operation and programming of the VLT 4000 VT.
The control panel is detachable and can - as
an al-ternative - be installed up to 10 feet away
from the VLT AFD, e.g. on the front panel, by
means of a mounting kit option.
The functions of the control panel can be
divided into five groups:
1. Display
2. Keys for changing display mode
3. Keys for changing program parameters
4. Indicator lamps
5. Keys for local operation.
All data are indicated by means of a 4-line
alpha-numeric display, which, in normal operation, is
able to show 4 operating data values and 3 operating
condition values continuously. During programming, all
the information required for quick, effective parameter
Setup of the VLT AFD will be displayed. As a
supplement to the display, there are three indicator
lamps for voltage (ON), warning (WARNING) and alarm
(ALARM), respectively. All VLT AFD parameter Setups
can be changed immediately via the control panel,
unless this function has been programmed to be
Locked
[1] via parameter 016

or via a
digital input, parameters 300-307

Control keys for parameter setup
The control keys are divided into functions. This means
that the keys between display and indicator lamps
are used for parameter Setup, including selecting the
display indication during normal operation.
[DISPLAY MODE] is used for selecting
the indication mode of the display or
when returning to the Display mode
from either the Quick menu or the
Extend menu mode.
