Local control panel

.
The Local Control Panel can be used to operate the
MCD3000 when in local control mode.
1. Numeric Display
During operation the display can show either
motor current (Amps) or motor temperature (%) as
calculated by the MCD3000 motor thermal model.
The information being displayed is indicated by
the LEDs to the right of the display, and can be
changed using the [+/-] buttons.
In the event of a trip the display shows the trip
code. Refer to the Fault Procedure section of this
manual.
ATTENTION
If motor current exceeds the maximum current
able to be shown on the numeric display, the
display will show dashes.

3. Operational buttons.
Can be used to control operation when the
MCD3000 is in local mode. Switch between local
and remote modes using the [LOCAL/REMOTE]
push button.
ATTENTION
Par. 20 Local / Remote Mode can be set to
prohibit either local or remote mode operation.
If the [LOCAL/REMOTE] button is used in an attempt
to switch to a prohibited mode the numeric display will
show 'OFF'.
Also, operation of the [LOCAL/REMOTE] push button
can be restricted to when the motor is stopped. In this
case pushing the [LOCAL/REMOTE] push button
results in the numeric display showing 'OFF'.
ATTENTION
When control power is applied the MCD3000
may be in either local or remote mode
according to the mode it was in when control power
was removed. The factory setting is local control.
ATTENTION
Simultaneously pressing the [STOP] and
[RESET] buttons causes the MCD3000 to
immediately remove voltage from the motor resulting in
a coast to stop. Any soft stop or D.C.Brake settings
are ignored.
4. Programming Buttons
Refer to the Programming Section of this manual.
5. Remote Control Input Status LEDs
Indicate the state of the circuits connected across
the MCD3000 remote control inputs.
ATTENTION
When control power is applied to the
MCD3000, all LEDs and Numeric Display
segments are illuminated for approximately 1 second
to test their operation.
