External Fault 2 (19,42)
This inputs allows for tripping or alarming of external protective devices or interlocks. When closed the fault is
healthy and when opened a trip and/or alarm occurs depending on the Tripping/Alarm settings. Auto-Reset when
enabled, occurs when the input contact closes.
External Fault 3 (20,43)
This inputs allows for tripping or alarming of external protective devices or interlocks. When closed the fault is
healthy when opened a trip and/or alarm occurs depending on the Tripping/Alarm settings. Auto-Reset when
enabled, occurs when the input contact closes.
External Test Position (20-43)
This feature can be provided as an alternative to the External Fault 3 input by means of a change in internal dip switch
settings prior to leaving the factory. The default setting is for this input is 'External Fault 3'. If required to be changed
on site, switch 1 , at the far right of the dip switch block situated on 2nd pcb from the top, ie with no connectors,
should be set to 'On' to provide the External Test facility, if set to 'Off' the input is used for External Fault 3.
If this option is selected a facility is provided to carry out function and protection testing on the motor starter
provided the starter is isolated. When this option is selected the Logical Input/Contact Status page will display in
place of the External Fault 3 the External Test status and will indicate 'Open = Run Enable' or 'Closed = Test' messages.
The Closed = Test status will only be achieved provid ing the Isolator N/O and N/C contacts confirm that the starter is
in the isolated position.
When in the Test mode the MPC2000 will ignore the Plant Interlock input and will disable Undercurrent Alarm & Trip,
Undervoltage, Single Phase and Phase Sequence protection functions to allow full functional testing to be performed
without the need for voltage or current injection and will allow secondary injection testing to be carried out on all
protective functions except for those disabled by the feature.If the External Test feature is required this should be
specified on the purchase order.
Emergency Stop (12,35)
This input allows the MPC2000 to monitor the status and provide indication of the state of any of the external
Emergency Stop buttons which are normally directly wired to the contactor closing circuit. Opening of the input
causes a trip or alarm depending on the Tripping/Alarms Settings.
6.3. Key Switch
A Key Switch can be optionally mounted on the front panel of the unit to give individual authorisation to an
MPC2000. If fitted the output for terminals 64 & 65 should be connected externally to the Authorise Key input
terminals 34 & 11.This option is only available for the 110/240 VAC version of the MPC2000.
6.4. Emergency Stop
An Emergency Stop Button may be optionally mounted on the front panel and internally wired to terminals 64,65 to
give direct hard-wired shut down and indication to the MPC2000. This option is only available for the 110/240 VAC
version of the MPC2000.
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.
