only. Failure to comply could result in death or serious
injury.
WARNING
UNINTENDED START!
When the frequency converter is connected to AC mains,
the motor may start at any time. The frequency converter,
motor, and any driven equipment must be in operational
readiness. Failure to comply could result in death, serious
injury, equipment, or property damage.
1. Confirm that the input voltage is balanced within
3%. If not, correct input voltage imbalance before
proceeding. Repeat this procedure after the
voltage correction.
2. Ensure that optional equipment wiring, if present,
matches the installation application.
3. Ensure that all operator devices are in the OFF
position. Panel doors should be closed or cover
mounted.
4. Apply power to the unit. DO NOT start the
frequency converter at this time. For units with a
disconnect switch, turn to the ON position to
apply power to the frequency converter.
NOTE
If the status line at the bottom of the LCP reads AUTO
REMOTE COASTING or Alarm 60 External Interlock is
displayed, this indicates that the unit is ready to operate
but is missing an input signal on terminal 27.

3.3 Basic Operational Programming

3.3.1 Set-up Wizard

The built -in "wizard" menu guides the installer through
the set -up of the frequency converter in a clear and
structured manner, and has been constructed with
reference to the industries refrigeration engineers, to
ensure that the text and language used makes complete
sense to the installer.
At start-up the FC 103 asks the user run the VLT Drive
Application Guide or to skip it (until it has been run, the
FC 103 will ask every time at start-up), thereafter in the

event of power failure the application guide is accessed
through the Quick menu screen.
If [Cancel] is pressed, the FC 103 will return to the status
screen. An automatic timer will cancel the wizard after 5
min. of inactivity (no keys pressed). The wizard must be re-
entered through the Quick Menu when it has been run
once.
Answering the questions on the screens takes the user
though a complete set-up for the FC 103. Most standard
refrigeration applications can be setup by using this
Application Guide. Advanced features must be accessed
though the menu structure (Quick Menu or Main Menu) in
the frequency converter.
The FC 103 Wizard covers all standard settings for:
-
-
-
These applications are then further expanded to allow
control of the frequency converter to be controlled via the
frequency converter's own internal PID controllers or from
an external control signal.
After completing set-up, choose to re-run wizard or start
application
The Application Guide can be cancelled at any time by
pressing [Back]. The Application Guide can be re-entered
through the Quick Menu. When re-entering the Application
Guide, the user will be asked to keep previous changes to
the factory set-up or to restore default values.
The FC 103 will start up initially with the Application guide
thereafter in the event of power failure the application
guide is accessed through the Quick menu screen.
The following screen will be presented:
