Operation
The Remote Operator performs all sort starter
functions except programming of the soft starter. The
Remote Operator can only be used to program its
own adjustable parameters. Uploading and
downloading of the soft starter parameters is
achieved locally at the soft starter or through the serial
communications network if connected.

Start Pushbutton: Starts the motor.
Stop/+ Pushbutton: Stops the motor.
Reset/- Pushbutton: Resets the soft starter.
NB!:
Simultaneously pressing the Stop/+ and
Reset/- pushbuttons causes the soft starter to
immediately remove voltage from the motor resulting
in a coast to stop. Any soft stop settings are ignored.
Data/Prog Pushbutton: Selects the parameter to be
shown on the display (Motor Current or Motor
Temperature).
Status LEDs: Indicate the status of the starter, and of
the RS485 link between the Remote Operator and the
starter.
Display Mode: Denotes the parameter shown on the
display (Motor Current, Motor Temperature, Trip
Code).
Display: Indicates the value of the selected data.
NB!:
Motor Current and Motor Temperature
information is only available on MCD 3000
and MCD 202 starters. If connected to a MCD 201
starter, the display will show 2222 instead of Motor
Current and 1.11 instead of Motor Temperature.
„
Trip Codes
If the soft starter trips, the relevant trip code is
displayed on the Remote Operator display. The
CODE and TRIP LEDs are illuminated. Some trip
codes are not available from all starter models – see
to the table below.
If the soft starter has an internal problem indicated by
a Code E (EEPROM Read/Write Failure) or Code U
(CPU Error) on its display, the soft starter will not
communicate with the Remote Operator. The
Remote Operator display will show four dashes and
the RS485 LED will flash.
