How to undo forcing changes and return the IED to normal
operation
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.

Undo forcing by using TESTMODE component

• If the IED test mode was entered through the test mode function block:
1. Deactivate the control input on that block.
This immediately undoes all forcing, regardless of how it was accomplished and
disabled all the way to force signals.

Undo forcing by using LHMI

• If the IED test mode was enabled to using the LHMI:
1. Set IEDTestMode to Off in the LHMI menu.
2. Exit from the menu and click Yes in the Save dialogue box.
This immediately undoes all forcing, regardless of how it was accomplished and
disabled.

Undo forcing by using PCM600

1. Uncheck Forcing Session under the menu IED.
