9.8.4 How to undo forcing changes and return the IED to normal

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.

all the way to force signals.
9.8.4.2

Undo forcing by using LHMI

• If the IED test mode was enabled to using the LHMI:

2.
This immediately undoes all forcing, regardless of how it was accomplished and disabled.

Regardless if the forcing changes are commited or canceled, the forcing is still
active.
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.
Deactivate the control input on that block.
