3. TECHNICAL DATA
3.1 Introduction
Softstart UK’s MIP-6 is a sophisticated OFF-Line
Motor Insulation measure and Protection unit.
The MIP-6 is designed for testing the insulation resistance of both Low Voltage and Medium Voltage motors
(Low voltage model and Medium voltage models are different models).
For Low Voltage motors, the MIP-6 is a stand alone unit.
For Medium Voltage motors, external RU7 (up to 7200V) or RU13 (up to 13800V) should be used.
The MIP-6 is a fully digital unit and can be used for all types of AC motors.
The MIP-6 measures:
•Actual insulation resistance.
When the optional real time clock is installed, the optionMIP-6 is capable to calculate:
•Last hour average insulation resistance.
•Last twenty four hours average insulation resistance.
•Last (previous) month average insulation resistance.
•Last (previous) year average insulation resistance
Two types of Minimum and Maximum insulation resistance levels are recorded. One type is for
the present month and the other for minimum and maximum levels, since the last reset.
All above parameters can be displayed and read through the optional RS485 communication.
Built in programmable time delay, prevents wrong insulation measurement due to motor cable capacitances
and motor induced voltages.
The MIP-6 relay protects the system from abnormal low insulation resistance condition in the motor and
cabling. Upon fault, the MIP-6 can alarm or trip the motor or prohibit starting.
The MIP-6 uses automatically Adjustable DC voltage level for the optimal Insulation resistance measurement.
To increase system and user safety maximum DC voltage is 50V.
Insulation measurement range is 0 – 50Mohm for both low voltage and medium voltage types.
The MIP-6 measures the insulation level when the motor is off line. Measurement is performed only when the
upstream line contactor is open. A discrete (digital) input is used to inform the MIP-6 if it should measure the
insulation resistance or not.
The MIP-6 cannot measure the insulation resistance when motor is powered. No damage will occur if the MIP-
6 connected properly when the motor is powered.
To prevent mistake and high insulation resistance reading, as a result of a disconnected measurement line,
Line Test feature enables user to perform line test and verify that the insulation measurement line is properly
connected. This feature tests also that the MIP functions normally. This feature applicable only to M.V. units.
In addition, internal self test is running in the background and testing the MIP-6. Manual self test can be also
performed.
The MIP-6 is fully programmable with 8 protection functions, including Insulation Trip, Insulation Alarm, Line
Test fail (M.V. units only!), optional Communication Port failure, Internal Fault and three External Faults.
The MIP-6 has a two line, 16 character LCD display and a six buttons keyboard for programming, reading
actual values, statistical & maintenance data.
3.2 Options
1. Real time clock. More than 21 years of data can be stored in the MIP-6. Data will be lost if MIP-
6 is disconnected from the auxiliary power supply voltage, for more than 2 weeks.
The MIP-6 is capable of storing and displaying the following historical values:
•Average Insulation resistances, hour by hour, of the last 24 hours.
•Average Insulation resistances, day by day, of the last 31 days.
•Average Insulation resistances, month by month, of the last 256 months.
•Average Insulation resistances, year by year, of the last 21 years.

5 • Technical Data
________________________________________________________________________________________________
2. RS-485 communication for MIP-6 programming, remote data readings and controlling.
3. Analog output. The MIP-6 can output present insulation level, 1 hour average, 24 hours average or one
month average.
3.3 MIP selection
Select the MIP-6 according to mains rated voltage.
Low Voltage – Up to 690V line to line.
Medium Voltage 1 – up to 7200V line to line (together with RU7).
Medium Voltage 2 – up to 13800V line to line (together with RU13).
3.4 Protection features
The MIP-6 alarms if the motor ground insulation level decreases below a preset value. This relay should
protect the motor against too low insulation resistance between motor windings and ground (earth).
For low voltage, up to 690V, the MIP-6 is directly connected to one of the motor phases. For MV, all three
motor phases are connected to an external resistor and protection unit RU7/13. The output of the RU7/13 is
connected to the MIP-6.
The MIP-6 incorporates one programmable Analog Output (optional) as well as six programmable discrete
inputs and six programmable output relays. Four relays are of the N.O. type with one common line to all four.
The other two relays are change-over (form C) type.
All inputs and outputs are combined to provide a very flexible package.
All output relays can be programmed as: TEST COMMAND OFF (M.V. units only!), TEST COMMAND ON
(M.V. units only!),INS. TST NOT ACT., INS. TST ACTIVE, INSUL. IN RANGE D, INSUL. IN RANGE C,
INSUL. IN RANGE B, INSUL. IN RANGE A, FAULT-FAIL SAFE, FAULT, ALARM-FAIL SAFE, ALARM, TRIP-
FAIL SAFE, TRIP,
In addition to the above programming options for all relays, each of A, B or C relays can be configured as
TRIPPING/ALARM as shown on the following table:
(i.e. - It is possible to assign certain faults to each one of the relays A, B or C.)
The MIP-6 can handle 8 different trips / alarms.
INSULATION TRIP Programmable level normally used to prevent starting the motor.
INSULATION ALARM Programmable level normally used to alarm that the insulation level is
decreasin
g
.
COMM PORT FAILED Used to alert for a communication port fault.
LINE TEST FAILED Used to alert when insulation test line is faulty. Applicable only in MIP-6 for
Medium voltage application (with RU7 or RU13).
INTERNAL FAILURE Background running self test program continuously tests the hardware and
software of the MIP-6. This protection can signal if an internal error occurs.
EXTERNAL FAULT 1
EXTERNAL FAULT 2
EXTERNAL FAULT 3
Three external fault inputs can be programmed to alarm or trip the motor.
Protection levels and time delay settings are programmable using the key pad on the front panel or through
communication.
Note that other relays – D, E and F can not be programmed as a TRIPPING/ALARM relays.
Refer to section 6.9.3 on page 23 for more details.

3.7 Optional serial link communication
The MIP-6 is equipped with an optional powerful data communication system.
This communication system is unmatched in its reliability, flexibility and ease of use providing the ideal basis
for the design of a modern motor management system.
The MIP-6 incorporates a rear RS485 serial link that uses a MODBUS RTU protocol (The protocol description is not
included in this document) to provide high speed data acquisition to supervisory computers.
Data formats have been carefully structured to provide fast notification of alarms and continuous updates of performance
parameters.
The following information and control can be accessed through the communication.
(See MIP-6 Communication instruction manual.)
•All Actual data values
•All MIP-6 Parameter Settings (Read & Write)
•All the control commands for the MIP-6 (Measure command, Test line)
•Reset
The MIP-6 system is user expandable. No special engineering skills or tools are required.
For small systems, the host computer can communicate directly with the MIP-6 via a twisted shielded pair.
For larger systems a data highway enables multiple MIP-6 connection. Up to 32 MIP-6s can be added on
each twisted pair of the Host serial link with full access to all MIP-6's.
The system also performs high speed data acquisition. Users have a simple and friendly means of creating a
fully integrated monitoring and control systems.
System reliability is exceptionally high, meeting the highest standards of reliable communication in the
industry. Included in each message is a 16 bit CRC.
Notes:
•Protocols other than MODBUS RTU available upon consultation.
•Terminate serial link cable with 120 Ohm resistors at both ends.
