How to undo forcing changes and return the IED to normal
operation
GUID-00E2BAD8-A29E-4B9D-80E6-E12F59E019BD v1
Regardless of which input/output signals have been forced, all forced signals will return to
their normal states immediately when the IED is taken out of test mode.
When the forcing is removed by exiting from IED test mode, both input and
output signals may change values. This means that logic input signals may
activate functions in the IED and that output relays may change state, which
can be potentially dangerous.
