Control Unit; Manual Initialisation - Danfoss VT2800 Series Design Manual

Control unit

On the front of the frequency converter there
is a control panel.
The control panel is di v ided into four function groups:
1. Six-digit LED display.
2. Keys for changing parameters and shifting
display function.
3. Indicator lamps.
4. Keys for local operation.
All displays of data are in the form of a six-digit LED
display capable of showing one item of operating
data continuously during normal operation. As a
supplement to the display, there are three indicator
lamps for indication of mains connection (ON),
warning (WARNING) and alarm (ALARM). Most of
the frequency converter's parameter Setups can be
changed immediately via the control panel, unless
this function has been programmed as Locked [1]
via parameter 018 Lock for data changes.
Control keys
[QUICK MENU] allows access to the parameters
used for the Quick menu.
The[QUICK MENU] key is also used if a change to
a parameter value is not to be implemented.
See also [QUICK MENU] + [+].
[CHANGE DATA] is used for changing a setting.
The [CHANGE DATA] key is also used for confirming
a change of parameter settings.
[+] / [-] are used for selecting parameters and
for changing parameter values.

These keys are also used in Display mode for
selecting the display of an operating value.
The [QUICK MENU] + [+] keys must be
pressed at the same time to gi v e access to all
parameters. See Menu mode.
[STOP/RESET] is used for stopping the
connected motor or for resetting the frequency
converter after a trip.
Can be selected as Acti v e [1] or Not acti v e [0] via
parameter 014 Local stop/reset. In Display mode, the
display will flash if the stop function is acti v ated.
NB!:
If the [STOP/RESET] key is set at Not acti v e
[0] in parameter 014 Local stop/reset,and
there is no stop command via the digital
inputs or serial communication, the motor can
only be stopped by disconnecting the mains
voltage to the frequency converter.
[START] is used for starting the frequency
converter. It is always acti v e, but the [START] key
cannot override a stop command.

Manual initialisation

Disconnect mains voltage. Hold the [QUICK
MENU] + [+] + [CHANGE DATA] keys down while
simultaneously reconnecting the mains voltage.
Release the keys; the frequency converter has now
been programmed for the factory setting.
