6.4 Alarm Types
The alarms in the ChemGuard® cabinet can be classified either as SHUTDOWN alarms or
FAULT alarms. Shutdown alarms appear on the SHUTDOWN ALARM box, in RED, located
in the top left hand corner of the screen. Fault alarms appear on the FAULT ALARM box, in
YELLOW, located in the top right hand corner of the screen. If <NONE> is displayed, no
alarm conditions are present. A time stamp of when the alarm occurred will be displayed with
each alarm.
Any alarm that occurs in ChemGuard® CG050 is displayed along with date and time stamp
indicating date and time of alarm occurrence. In addition, independent output signals for
shutdown and fault alarm are sent to the available IO connections in controller.
A SHUTDOWN alarms sets off a buzzer, which continues to sound until the alarm has been
cleared. A shutdown alarm LED flashes red when an un-acknowledged shutdown alarm is
present. The Alarm can be acknowledged by clicking anywhere on the alarm text box.
