P.7 Alarms
Failure detected by the system will activate Failure mode while in any mode of
operation. Failure mode causes the motor rotation to stop, displays an alarm
notification to the operator (Figure 55) and generates and alarm output signal for
remote control.
The equipment in the drive unit will stay powered up but cannot be operated until
failure reset is complete. Failure resolution is available only from the LevMixer face
panel. External control equipment will only receive an alarm signal with no ability to
feedback control.
IMPORTANT: If failure happens while any of Editor screen is opened the alarm is
generated but notification will not appear on screen until escape from Editor to any of
Mode screens.
Reset of the failure mode is available from the failure detection screen (Figure 56) which
is opened after pressing the
Alarm button.
