NOTE
If the device is faulty due to a Card error and/or MLFB error, it must be returned via the standard Siemens
returns process. Contact your regional office.
NOTE
Internal supply voltage error and card error is seen on device HMI only when user applies CT power or auxil-
iary power supply.
NOTE
If a binary output is assigned to IRF, Siemens recommends not to use the same binary output for any other
protection function configuration.
If a binary output is assigned to IRF, and if there is an internal relay failure, then the binary output is reset.
