The ILT-710-V.5 is a multifunctional monitoring device for medical IT systems, specifically designed for use in accordance with the IEC 60364-7-710 and DIN VDE 0100-710 standards. As an integral component of the HospEC® system, it combines several essential monitoring functions in one compact module.

Main Monitoring Functions

• Insulation monitoring: The device continuously monitors the insulation resistance of single-phase medical IT systems (AC 110–230 V).

• Load current monitoring: It measures the load current of single-phase IT system transformers using a special external current transformer (type ILT-W).

• Temperature monitoring: The transformer's temperature is reliably monitored using PTC thermistors or break contacts.

Insulation Fault Detection (IFS)

• The ILT-710-V.5 features an integrated test signal generator.

• In combination with at least one insulation fault detection device (e.g., the IFS-710-W6), it can be expanded into a complete insulation fault detection system in accordance with IEC 61557-9.

• If a fault occurs, a test signal is fed in, which allows the defective outgoing circuit to be exactly localized and its name (e.g., fuse designation) to be shown on the display.

Operation and Display

• The device is equipped with a full-graphics LCD display (128x64 pixels with white backlighting), which clearly shows all operating and fault messages in plain text.

• A multi-coloured "Status" LED indicates the current operating status at a glance (e.g., green for normal operation, flashing red for device errors, yellow when response values are exceeded).

• User-friendly parameterization is carried out via four control keys.

• A non-volatile message memory logs up to 200 events with a date and time stamp.

Communication and Interfaces

• All messages are transmitted to peripheral operating and annunciator terminals via the integrated CAN bus (CAN 2.0, Protocol: ESA-CAN).

• The device supports the Modbus RTU protocol (as a slave) via an RS485 interface.

• Two configurable connections for fault signalling relays enable easy integration into the building control technology (BSCS).

Safety and Standard Compliance

• The ILT-710-V.5 performs continuous automatic self-monitoring, including a PE and KE connection test every 30 minutes, as well as checking the transformer connections for interruptions and short circuits.

• An integrated test alarm function monitors the operator's obligation to carry out periodic inspections (e.g., according to DIN VDE 0100-710).

• The device is CB-certified by VDE and meets international standards such as IEC 61557-1, IEC 61557-8, IEC 61557-9, and IEC 61010-1.
