USE
GENERAL
The Superintend IMD IND consists of several separate modules integrating into an
insulation monitoring system through an electronic communication bus. The system
includes the following components:
• The IM-01.IND unit is the central unit of the system. It performs most of the
measurements independently and controls the operations of the other units and
the alarm relays. The IM-01.IND unit is installed in the switchboard.
• The CLT-01 unit is a current loop transmitter for insulation resistance with a
standard 0…20 / 4…20 mA current message. It is installed in the switchboard.
• The PEC-01, TC-01 and IC-01 units are available as accessories. They have
originally been designed for medical locations. These devices are discussed in
more detail in the Superintend IMD MED
– Installation and User Manual.
IM-01.IND UNIT
The IM-01.IND unit is the central unit of the system and the host of the RS-485 bus
connected to it. The IM-01.IND contains the user interface of the entire system, and it
controls all CLT-01 and possible other units connected to it. The error notifications are
displayed on the screen of the IM-01.IND, and the fault information can be forwarded to
another user-defined system through alarm relays. All alarm parameters are set through
the user interface of the IM-01.IND system.
In addition, the IM-01.IND unit maintains three separate log files on the microSD
memory card if the memory card is inserted in the card slot and enabled in the Setup
menu. They are Excel-compatible text files, which can be transferred to any computer
for more detailed analysis. For more detailed information, see section “Log files”. If the
memory card function is not enabled, only the most recent information of each log entry
is stored in the device memory. The information that is not stored on the memory card
will not be preserved in the memory if the device loses operating voltage.
Measurement values can be monitored and settings can be changed using the
Modbus/TCP protocol via the IM-01.IN
D unit’s E thernet connection. For this purpose, the
device RJ45 must be connected to the local area network and the TCP/IP parameters
must have been configured in the Setup menu.
The IM-01.IND unit independently measures the insulation resistance and capacitance of
the IT network to be monitored, in relation to protective earth. The measurement is
performed by feeding two separate low-frequency alternating voltages between the
network and the PE conductor. These generate a low current that travels through the
insulation resistance and capacitance to be measured. The insulation resistance and
capacitance are calculated by measuring the current amplitude and phase. In addition,
