Configuring hardware components for ANSI

The Insulation Monitoring application includes several hardware components. Some of these components communicate on an internal bus and must be configured with unique IP addresses and unit IDs.

Set up the parameters for the installed hardware as described in this section.

Isolated Power Panel

The isolated power panel includes the circuit monitoring devices such as the IG6.

See the Bender Resources Web site for circuit monitoring device installation instructions.

NOTE: Make sure the clocks on all devices are correctly configured during commissioning so that the reports you run show the correct timestamp.

IGC COM460/COM461/COM465IP Gateway

In the Insulation Monitoring application, the IGC COM460/COM461/COM465IP Gateway converts the serial Bender BMS protocol to Modbus TCP. For this solution, note the following:

• The IP address must be unique. Set up the IP address so that the software can communicate with it.

  NOTE: Make sure to always set the unit ID to 1. Doing this sets the gateway to Master mode on the Bender bus.

• Set the gateway to operate on its internal bus.

See the Bender Resources Web site for instructions on how to configure the gateway.

Line Isolation Monitor

The Iso-Gard™ IG6 line isolation monitor (LIM-IG6) is installed in the isolated power panel. This device continuously calculates the total hazard current (THC) by measuring the leakage impedance between isolated line and ground. Up to two LIM-IG6 monitors can be installed in one panel.

NOTE: Set the Unit ID of the LIM IG6 to immediately succeed the Unit ID of the COM460.

For example, if you have a branch of COM460s with the devices connected to it, such as three IG6s, two EDS 461s, and one CMS 460, then set the Unit IDs as follows:

Device Type	Unit ID
COM460	1
LIM-IG6	2
LIM-IG6	3
LIM-IG6	4
EDS 461	5
EDS 461	6
CMS 460	7

• Set the Unit ID of the Serial devices that are connected to the IGC COM46x gateway.
• Set the total hazard current level to the appropriate value for your location.

NOTE: Make sure the clocks on all devices are correctly configured during commissioning so that the reports you run show the correct timestamp.

See the LIM-IG6 documentation for instructions on how to install and operate the device.

Circuit Fault Locator (Optional)

The EDS 151 and EDS 461 circuit fault locator identifies the specific circuits where insulation faults could result in current leakage that exceeds the defined total hazard current level. For this solution, note the following:

NOTE: Make sure the clocks on all devices are correctly configured during commissioning so that the reports you run show the correct timestamp.

• Set up the unit ID on the device. This ID must be unique from the unit ID and serial ID of other devices.

See the EDS 151 and EDS 461 documentation for instructions on how to configure the device.

Circuit Load Transformer (Optional)

The solution can include an optional SWT3 or SWT4 circuit transformer for load monitoring.

See the LIM-IG6 documentation for instructions to connect wiring to the circuit transformer and configure the device.

Temperature Sensor (Optional)

The temperature sensor monitors the temperature of the isolation transformer, if installed. Temperature data appears in the Vista diagrams if the device is installed and set up in the configuration tool.

See the LIM-IG6 documentation for instructions to connect wiring to the temperature sensor and configure the device.

Load Current Evaluator (Optional)

The CMS460 Load Current Evaluator is used to detect, monitor and evaluate loads and installation for load currents in power supplies.

NOTE: Make sure the clocks on all devices are correctly configured during commissioning so that the reports you run show the correct timestamp.

• Set up the unit ID on the device. This ID must be unique from the unit ID and serial ID of other devices.

See the CMS460 Load Current Evaluator documentation for instructions on how to configure the device.

After the parameters for the hardware components are configured, set up the communications for the devices as described next.
