The IFS-STL-710-W6 is an advanced insulation fault detection device designed as an integral component of insulation fault detection systems, specifically for medical locations in accordance with DIN VDE 0100-710. The device enables the fast and automatic localization of faulty current circuits during operation, eliminating the need for time-consuming manual fault detection.

Main Features and Technical Specifications

• Integrated measuring current transformers: The device is equipped with six integrated measuring current transformers to separately detect test currents for each outgoing circuit.

• Parallel measurement recording: The detection and processing of measured values is carried out in parallel on all channels (no multiplex procedure), ensuring immediate evaluation.

• High-precision evaluation range: The evaluation range for leakage currents is 5 µA to 2.5 mA.

• CAN bus integration: Both the power supply (DC 15...30 V) and all communication are carried out efficiently via the CAN bus.

System Integration and Operation within the HospEC® System

• The IFS-STL-710-W6 operates in conjunction with a test current generator, which is either external (e.g., IFS-710-PSG) or integrated internally within higher-level monitoring devices such as the UEI-710-V.5, ILT-710-V.5, or ILT-107-V.4.

• If the insulation resistance in the IT system falls below a defined value, the generator feeds a test signal into the system (limited to max. 1 mA in medical locations).

• The IFS-STL-710-W6 detects this signal and transmits the exact data of the faulty circuit via the CAN bus to the higher-level monitoring device as well as to peripheral annunciator terminals.

• The system is highly scalable: up to 16 IFS-STL-710-W6 devices can be combined to monitor a maximum of 96 measurement channels per IT system.

Operation and Display

• The device operates fully automatically and requires no handling during operation; no manual intervention is needed.

• Eight multi-coloured LEDs on the front visualize the system status: one Status LED, one CAN LED for communication monitoring, and six channel-specific LEDs (T1 to T6).

• The channel LEDs light up green when the insulation is intact and change to yellow when an insulation fault is detected.

Installation and Standard Compliance

• The device fulfills the strict requirements of DIN VDE 0100-710 (VDE 0100 Part 710) for medical areas and carries the CE mark.

• It is installed as a rail-mounted device on a standard top-hat rail in accordance with DIN EN 60715.
