Lock/unlock button
By default, the protection settings for the Energy trip unit are prevented from being
modified by locking the navigation function of the embedded display.
Navigation is still possible in order to view the data.
Locking prevents any inadvertent modification of the trip unit settings by
unauthorised personnel, which would affect the protection level of the trip unit,
the measurements taken and its remote communication capabilities:
- Reset measurement statistics
- Return to the factory settings of the embedded display
- Modification of the data write locking parameter.
If there is an attempt to modify a locked parameter using the joystick, a padlock
is displayed on the screen to indicate that the locking function is active.
Embedded display locked
To unlock access in order to be able to modify the settings, it is necessary to open
the transparent flap and access the unlock button or the Ir max adjustment selector.
There are two ways to unlock access:
- By using the Ir max adjustment dial
- By pressing the unlock button.
