Alarms

Up to four electromechanical alarm relays are available to activate external equipment

when preset alarm setpoints are reached. Each of the four alarms can be set to monitor

two independent setpoints. Each alarm setpoint can be either high or low alarm. The

alarm type can be selected to be either of the inputs, the Process Variable, Deviation,

Output, Shed from communications, PV rate of change, or to alarm on manual mode

activation or a Current Output Open failure. It can also be used as an On or Off event at

the beginning or end of a Ramp/Soak segment. An individual alarm hysteresis setting is

provided for each relay and these are configurable from 0 to 100% of range.

 Alarms can be configured as latching or non-latching. continued

 Alarm blocking is also available which allows start-up without alarm energized
