Safety standards compliance requirements
The device is SIL 2 and SIL 1 certified in compliance with IEC 61508: 2010 (standard related to Functional Safety) and IEC 61557-15: 2014 (based on IEC 61508, specific for IT systems using IMDs and IFLs devices).
The classification of safety function:
RIW (Remote Insulation Warning)
Used with redundant actuators
RIW (Remote Insulation Warning) or REDC (Remote enabling / disabling command)
Used with single actuator
The following model and commercial references are certified:
The device and accessories (voltage adaptors) certification is valid if the installation and wiring of the system abides with the description explained.
To comply with the Functional Safety Standards requirements, the device must be configured using the following parameters, accessible by selecting:
|Ins. Al. Relay
|Insulation alarm relay
|Prev. Al. Rel
|Preventive insulation alarm relay
|Injection inhibition input
|N.O or OFF
|Acknowledgement of the inhibition signal
|Ack. Al. Relay
|Allow triggering relays when acknowledging alarm
|Corr. Flt. Signal
|Allow 3s signal when insulation fault disappears
|Test w. Relays
|Toggle Relays during manual auto test
For detailed information about these parameters, see I/O configuration.
