Control Unit; Manual Initialization - Fantech VLT 2800 Series Instruction Manual

Control unit

On the front of the variable frequency drive
there is a control panel.
The control panel is divided into five functional groups:
1. Status LED
2. Keys for changing parameters and shifting
display function.
3. LEDs.
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 LEDs
for indication of electrical connection (ON), warning
(WARNING) and alarm (ALARM). Most of the
variable frequency drive'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 give access to all
parameters. See Menu mode.
[STOP/RESET] is used for stopping the
connected motor or for resetting the variable
frequency drive after a trip.
Can be selected as Active [1] or Not active [0] via
parameter 014 Local stop/reset. In Display mode, the
display will flash if the stop function is activated.
NOTE
If the [STOP/RESET] key is set at Not active
[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 electrical
voltage to the variable frequency drive.
[START] is used for starting the variable frequency
drive. It is always active, but the [START] key
cannot override a stop command.

Manual initialization

To manually initialize the adjustable frequency drive to
factory default settings, first disconnect AC line voltage.
Hold the [QUICK MENU] and [+] and [CHANGE DATA]
keys down while simultaneously reconnecting the AC
line voltage. Release the keys. The drive has now
been programmed for factory settings.
