Locating

Applicable for IM400, IM400C*, and IM400L.

You can use the device with automatic insulation fault locator or manual insulation fault locator to locate the insulation fault.

You can use the following automatic insulation fault locators:

IFL12: Twelve-channel insulation fault locator with one LED indicator per channel and one output relay (commercial reference: IMDIFL12)
IFL12C: Twelve-channel insulation fault locator with LCD display ( indication for 12 channels) and one output relay (commercial reference: IMDIFL12C)
IFL12MC: Twelve-channel insulation fault locator with LCD display (indication for 12 channels with R, C, and Zc display) and one output relay (commercial reference: IMDIFL12MC)
IFL12LMC: Twelve-channel insulation fault locator with LCD display (indication for 12 channels with R, C, and Zc display), low voltage auxiliary supply, and one output relay (commercial reference: IMDIFL12MC)
IFL12MCT: Twelve-channel insulation fault locator with LCD display (indication for 12 channels with R, C, and Zc display) and one output relay with conformal coating (commercial reference: IMDIFL12MCT)
IFL12LMCT: Twelve-channel insulation fault locator with LCD display (indication for 12 channels with R, C, and Zc display), low voltage auxiliary supply, and one output relay with conformal coating (commercial reference: IMDIFL12LMCT)
XD301: One-channel insulation fault locator with indicator light and one output relay (commercial references 50506, 50507, and 50508)
XD312: Twelve-channel insulation fault locator with one indicator light per channel and one output relay (commercial references 50535, 50536, and 50537)
XD308C: Eight-channel insulation fault locator with communication (requires an XLI300 communication interface) (commercial references 50723, 50724, and 50725)

NOTE: You are strongly advised to use the following devices:

IFL12
IFL12C
IFL12MC
IFL12LMC
IFL12MCT
IFL12LMCT

You can use the XRM manual insulation fault locators.

Four values are available for this parameter:

Value	Advised Usage
OFF	The device does not inject a fault locating current.
IFL	The device injects a fault locating current when an insulation alarm is detected and compatible with IFL12, IFL12MC, IFL12LMC, IFL12MCT, and IFL12LMCT devices.
XD	The device injects a fault locating current when an insulation alarm is detected and compatible with XD301, XD312, XD308C, and XRM devices.

NOTE: Insulation fault location is not compatible with IM400-1700, IM4000VA2, and P1N voltage/ground adaptors.
