MPS 3000-P/C Installed in MV Cabinet If the MPS uses separate (not the internal soft starter) CTs and PTs (current and voltage transformers), then set all MPS parameters according to the instruction manual.

If, however the MPS uses the Medium Voltage starter Internal CTs and PTs, then few parameters settings must be done as explained here.

Inside the soft starter, there is an electronic Potential Transformer. It’s “primary” rated voltage is equal to the starter rated voltage. It’s “secondary” rated voltage is 120VAC.

Inside the soft starter, special CTs are used. Their primary rated current equals to the starter rated current. Their secondary rated current is 2A. The secondary current is connected to the MPS 5A input.

In the SYSTEM PARAMETER setting page, please set:

LINE VOLTS= Actual rated line voltage (should be equal or lower than starter rated voltage).

VT PRIMARY = Starter rated voltage (the Electronic Potential Transformer is calibrated tothe starter rated voltage).

VT SECONDARY = 120 (the EPT “secondary” rated voltage).

40 March 31, 2008

MOTOR FLC = Actual Motor Name Plate (Rated) current (should be equal or

lower than starter rated current).

CT PRIMARY = 2.5 * Starter Rated Current.

GND CT PRIMARY = same as CT PRIMARY setting.

Explanation of CT PRIMARY: If The rated starter current is - for example -

250A, it's CTs (that are used also for the MPS) are 250 / 2A.

Please note that CTs secondary current is 2A, not 5A. The MPS current input used

is 5A.

When 250A flows, the MPS gets only 2A instead 5A and will calculate 2 / 5 *250 =

100A.

Therefore we have to set the CT Primary to 250*(5/2)=625, which with 2A will read

exactly 250A as required.

Please note that in the MPS3000, you have to store each parameter separately (while

in the starter you store all parameters of a page together

TPR 6

Temperature Protection Relay

69 March 31, 2008

TPR-6 Temperature Protection Relay

Monitoring 6 to 14 temperature sensors (RTD/Thermistor).

The TPR-6 accurately creates “Thermal Levels” of the heat increase to protect the motor from abnormal heat in the windings and or bearings.

Self test procedure protects against disconnected sensors and operator faults.

Warning

* The analogue output circuit is

isolated as a group together with

the RS485 communication.

When using both connections,

verify that analogue out user (or

RS-485 user) is using isolated

circuitry.

* Connect all shield wires to

Ground. (A short busbar may be

used).
