Process Alarms
The process alarms can be setup to activate either or both of the two alarm contacts provide on the VersaPro.
Nine user selectable modes are available. The Full Scale HI, Full Scale LO, Fault, and Probe alarms are
available in the monitor. Of the alarms listed are available in the controller.

Disables the alarm function and the alarm contacts
Full Scale HI
An alarm is generated any time the process value goes above the Full Scale HI alarm value. This alarm is
reset if the process falls below the alarm value or acknowledgement from the front panel or through the
event input (if configured).
Full Scale LO
An alarm is generated any time the process value drops below the Full Scale LO alarm value. The alarm
will arm once the process is measured above the alarm value. This alarm is reset with an
acknowledgement from the front panel or through the event input (if configured).
Deviation Band
An alarm is generated any time the process value goes above or below the band alarm setting. The alarm
setting is
value of the band. For example, if a value of 10 is entered as the alarm value, an alarm is
generated if the process goes 10 units above or 10 units below the setpoint. Units are the process units
such percent or degrees. This alarm will not arm until the process is in-band of the setpoint.
Deviation High
An alarm is generated any time the process value goes above the band alarm setting. The alarm setting
is number of units allowed above setpoint. Units are the process units such percent or degrees. This
alarm will not arm until the process is in-band of the setpoint.
Deviation Low
An alarm is generated any time the process value goes below the band alarm setting. The alarm setting is
number of units allowed below the setpoint. Units are the process units such percent oxygen or degrees.
This alarm will not arm until the process is in-band of the setpoint.
Output High
An alarm is generated any time the control percent output exceeds the alarm value. The alarm setting is
maximum percent output allowed.
