Parameter: Enabled in Local
•
Default Setting: <All>
Operation of the selected binary input is enabled when Device Config > Operating Mode is
selected to Local, (see 3.2 Device Configuration ).
Parameter: Enabled in Remote
•
Default Setting: <All>
Operation of the selected binary input is enabled when Device Config > Operating Mode is
selected to Remote, (see 3.2 Device Configuration ).
Parameter: Enabled in Out of Service
•
Default Setting: <All>
Operation of the selected binary input is enabled when Device Config > Operating Mode is
selected to Out of Service, (see 3.2 Device Configuration ).
Parameter: Inhibit <Function>
•
Default Setting: <None>
When operated the binary input initiates the reset sequence of the relevant function element(s).
Parameter: Ext Trig 60VTS
•
Default Setting: <None>
Used to initiate the VT supervision function (60VTS) time delay element from a MCB connected in the VT
secondary circuit, (see 6 Supervision Functions , section 60VTS VT Supervision).
Parameter: Ext Reset 60VTS
•
Default Setting:
Used to reset the VT supervision function (60VTS) when a VT failure condition no longer exists, (see
6 Supervision Functions , section 60VTS VT Supervision).
Parameter: 50BF-n CB Faulty
•
Default Setting: <None>
This input is connected to the CB monitoring circuits. If this input is operated when a trip initiation is
received an output will be given immediately (the timers are by passed), (see 6 Supervision Functions ,
section 50BF Circuit-Breaker Failure Protection – 3 Pole).
Parameter: 50BF-n Mech Trip
•
Default Setting: <None>
Used to trigger the circuit‑breaker fail function. A binary input configured as CB Closed must also be
energized to confirm CB failure, (see 6 Supervision Functions , section 50BF Circuit-Breaker Failure
Protection – 3 Pole).
