QAK Unlock Key
The Unlock key, symbolized by an open padlock, is used to enable the QAKs. This feature was incorporated to avoid features being activated or deactivated accidentally.
The QAK Unlock key is configurable through the OCP Configuration Tool in WSOS but by default, an operator has to unlock the QAKs before they can be used and a LED above the Unlock Key changes from red to green when the QAKs are unlocked.
The QAKs can be locked by pressing the Unlock key again or they will lock automatically after a configurable delay (10 s by default) if no QAKs are pressed.
If required, users can disable the locking feature on any or all of the QAKs.
For example, to activate the Ground Fault element the operator must press the following keys:
-
Quick Action Unlock Key – The LED on this key must change from red to green to indicate that the QAKs are unlocked.
-
Ground Fault Key – The LED on this key must change from OFF to ON (Red) to indicate that Ground Fault protection is activated.
