Control Unit; Manual Initialisation; Change Data; Control Panel - Danfoss VLT 2800 Series Operating Instructions Manual

Control unit

On the front of the frequency converter there is a

control panel.

The control panel is divided 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), warn-
ing (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

tive [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.

It is always active, but the [START] key cannot over-
ride a stop command.

+ [+] + [CHANGE DATA] keys down while simultane-
ously reconnecting the mains voltage. Release the
