7. MPC2000+ Faceplate Functions

The MPC2000+ 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.

7.1. LED Status Panel

This panel incorporates 10 LED indicators which provide the main status indications for the Motor Starter panel
The LED's operate as follows:
POWER
This green LED illuminates when the auxiliary supply voltage to the MPC2000+ 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.
If 'Protection Only' mode has been selected this LED illuminates after a motor has started and when the running
current falls below 110% of the Overload Setting.
RELAY A This red LED illuminates when Contactor A is closed, indicating that the DOL, Star, Forward or Low
speed contactors are closed.
