9.8. Alarms
Failure detected by the system will activate Failure mode while in any mode of operation. Failure
mode halts motor rotation, displays an alarm notification on screen (Figure 35 left) and generates
an alarm output signal for remote control. Alarm light changes the color from green to red and
audible signal comes to beeping.
The equipment in the drive unit will stay powered up but cannot be operated until failure reset is
complete. Failure resolution is available only locally from the magnetic mixer 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 open the alarm is generated and
indicated via alarm light and sounder but notification will not appear on screen until escape from
editor to any of mode screens.
