Page 12: Mpc2000D Measured Inputs
MCC busbars to provide an Undervoltage Dip Restart facility. When enabled in the System Settings page the MPC2000D monitors the supply and in the event of a failure will maintain the start signal to the motor for upto 200 msec, beyond 200 msec the unit will trip the motor and should the Power supply be restored within 4 seconds the unit will restart the motor after a time delay set in the Undervoltage Settings page. -

MPC2000D and the should always be isolated prior to working on the wiring at the rear of the unit. - Page 14 Local/Remote (74,73) This contact allows control of the MPC2000D to be switched between local control ( via Start A and Start B Input Terminals (68,67-66,65)) or remote control either via the direct wired PLC inputs or via the RS485 serial link . It is also only possible to reset the MPC2000D after a fault from the front panel without authorisation if the MPC2000D is in the Local control mode.
- Page 15 Emergency Stop (31,32) This input allows the MPC2000D 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.

Page 16: Mpc2000D Faceplate Functions
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. -

FAULT This red LED illuminates when one or more of the MPC2000D Fault functions has operated and stopped the motor. It remains lit until the condition no longer exists and a reset has been performed. Note it is not possible to reset a Fault whilst a Start signal is maintained. - Page 18 If the STORE key is pressed whilst the display shows a Data parameter then the parameter currently being displayed will be set as the default display which the MPC2000D will always revert to if no key is pressed for 5 minutes and provided a flash or constant message is not being displayed.

This setting, range 'Not Connected ' or 95V-660V in steps of 5v, with a default setting of 'Not Connected', allows for systems with voltages above 660V , where the voltage reference to the MPC2000D must be via a voltage transformer and the VT secondary voltage is set with this function. - Page 21 'Trip' determines the use of the Aux 2 relay. Aux.2 Delay This setting range 0-120s in steps of 1s, with a default setting of 0, allows the user to set a time delay on the operation of the Aux.2 relay. Page 18 Issue 2 22/4/98 MPC2000D...

Number of Starts The number of starts the motor will make can be limited by the MPC2000D from anywhere between the range of 1 to 10 in steps of 1, with a default setting of 10. - Page 24 Time This setting specifies the time the MPC2000D will take to trip at 6 times FLC and determine the basic thermal characteristic. This time range 0.5 and 120 seconds, with a default setting of 10 seconds. For further information refer...

This message is displayed constantly after the MPC2000D has recognised a Hard Wired Stop, this is defined as a motor stop which is not the result of an MPC2000D command or the Emergency Stop Indication input.. The message remains displayed until the reset button pressed. -
Page 36: Mpc2000D Fault Finding
14. MPC2000D Fault Finding This procedure details some of the more common faults which may cause the MPC2000D to not operate as required. This is usually due to incorrect settings or logic and will hopefully assist to rectify the situation. -
Page 37: Mpc2000D Thermal Overload Protection
For example if the Hot/Cold ratio setting is 60% and the motor has been running at normal FLC for some time the amount of thermal capacity available is 60% then the amount displayed by the MPC2000D is the amount used which is 100 - 60 = 40%. - Page 38 MPC2000D. If a motor speed switch is installed and connected to the MPC2000D it is then possible to decrease the thermal trip time in the range of 20-100% of the set hot & cold curve operating times when the motor stops rotating, i.e. stalled.
