7. MPC2000D Faceplate Functions
The MPC2000D Faceplate has been designed to provide all of the required information to the operator for the drive
for which the unit is being used.
This is achieved by using a LED Status Panel and a Functional Keypad with a LCD display.
This eliminates the need for additional indication devices on the front of the motor starter panel such as Lamps,
Ammeter, Voltmeter, Hours Run Indicator, Operations Counter, etc. which helps reduce the cost of the motor starter
panel and gives improved reliability by reduction of separate components.
The following section details the function of the Frontplate devices.
LED Status Panel
This panel incorporates 9 LED indicators which
provide the main status indications for the Motor
Starter panel
The LED's operate as follows:
MPC POWER ON
This green LED
illuminates
when the auxiliary supply
voltage to the MPC2000D unit is connected.
STOPPED
This green LED illuminates on
power up. The LED illuminates when both
contactor A & B inputs indicate a open state and
also when a Stop or Fault signal is present.
STARTING
This amber LED is illuminated when a Start command is received and remains illuminated
providing either Contactor A or B are closed and the average motor current is 110% or above of the Overload Setting.
If 'Protection Only' has been selected this LED will be illuminated when the current inputs detect a running current
above 110% of the Overload Setting and will remain illuminated until the current falls below this level.
RUNNING
This red LED illuminates after a start has been completed providing either Contactor A or B are
closed and the average motor current has decreased to below 110% of the Overload Setting.
CONTACTOR A
This red LED illuminates when Contactor A is closed, indicating that the DOL, Star,
Forward or Low speed contactors are closed.
CONTACTOR B
This red LED illuminates when Contactor B is closed, indicating that the Delta, Reverse or
High speed contactors are closed.
ALARM
This red LED indicates that one of the MPC2000D Alarm functions has operated and remains lit
until the condition no longer exists and a reset has been performed. Note it is not possible to reset an Alarm whilst a
start signal is maintained.
