• initiating
• blocking
• setting group selection
• function trigger inputs.
The function can be initiated by a digital input, or by a circuit breaker "Close" command connected to
the "
SOTF activate input" input. The duration of the SOTF-armed condition can be set by the "Release
time for SOTF" setting parameter; it can be changed if the application so requires through setting group
selection.
The outputs of the function are BLOCKED, ACTIVE and TRIP signals. Additionally, the function outputs
the corresponding events and registers when any of these mentioned signals activate.
The following figure presents a simplified function block diagram of the switch-on-to-fault function.

Input signals
The function block does not use analog measurement inputs. Instead, its operation is based entirely on
binary signal statuses.
Table. 5.4.4 - 156. Input signals.
Input Description
Activate
input
The digital input or logic signal for the function to arm and start calculating the SOTF time. Any binary signal can be
used to activate the function and start the calculation. The rising edge of the signal is considered as the start of the
function.
Block
input
The input for blocking the function. Any binary signal can be used to block the function from starting.
Function
input
The function input activates the function's instant trip if applied when the function is calculating the SOTF time.
Settings
The switch-on-to-fault function has one setting and it determines how long the function remains active
after it has been triggered. If the inputs receive any of the set signals during this time, the function's trip
is activated.
