Display:
Indicates the value of the selected data.
Status LEDs:
Indicate the status of the starter, and of the RS485 link between the Remote Operator
and the starter.
•
The Start LED (Green) indicates that the soft starter is starting, running or stopping.
•
The Run LED (Green) indicates that the soft starter is providing full voltage to the motor.
•
The Trip LED (Red) indicates that the soft starter has tripped.
•
The RS485 Status LED shows the condition of the serial link between the Remote Operator and the soft
starter. When this is illuminated the connection is healthy. When the LED is flashing there has been loss of
communication.
N.B.!:
Motor current and motor temperature information is only available from MCD 202,
MCD 500 and MCD 3000 starters. If connected to an MCD 201 open loop soft starter, the
display will show 2222 instead of motor current and 1.11 instead of motor temperature.
N.B.!:
When using the Remote Operator with MCD 500 models MCD5-0023B ~ MCD5-0068B, the
motor current and analog output must be normalised using Pars. 6 and 9. =>
Programmable Parameters for details.

Trip Codes
If the soft starter trips, the CODE and TRIP LEDs illuminate and the relevant trip code is reported on the
Remote Operator display. Some trip codes are not available from all starter models.
