If more than one alarm or status message occurs at the same time, they will be scrolled at
two (2) second intervals in the alarm area of the Device Status Screen. Any number of
alarm or status messages may be present.
NOTE:
Alarms that cause a control to trip require that the ON/OFF switch on the
front of the control cabinet be turned to OFF then ON to reset the control.
The Alarm Clear key must be pressed to clear the alarm from the display
after the cause has been remedied. If the alarm condition is still present,
the control will again trip.
