Acknowledge
If an object has an unacknowledged alarm, that object’s Acknowledge button
is blue. Clicking this button sends an ACK command to the controller and
acknowledges alarms for the object or the group in the alarm function.
Local Mode
Clicking the Local button enables the Local mode of the object. This means
that the object can be controlled at the motor by the Start and Stop buttons.
The Local Mode is active when the button is white. This function can be
switched on or off by the Group module.
