Module Properties dialog box - Alarms page parameters (5094-IJ2IS, 5094-IJ2ISXT)

Select to help prevent the module from generating any of the four process alarms (LL, L, H, and HH) or the Acceleration and Deceleration alarms, and disable access to any of the alarm configuration properties.

Select to instruct the module to latch any or all of the four process alarms (LL, L, H, and HH) once the alarm has been triggered, even if the condition causing the alarm to occur disappears.

Enter the trigger point in Engineering Units. HHAlarm is set to 1 when the input signal moves above this limit.

Move the

HH

marker down or up to set the

High High

value. As you move the marker, the

High High

value changes to match the value of the

HH

marker. The

HH

marker corresponds to the

High High Limit

value.

Enter the trigger point in Engineering Units. HAlarm is set to 1 when the input signal moves above this limit.

Move the

HI

marker down or up to set the

High

value. As you move the marker, the

High

value changes to match the value of the

HI

marker. The

HI

marker corresponds to the

High Limit

value.

Enter the trigger point In Engineering Units. LAlarm is set to 1 when the input signal moves below this limit. The Low Alarm Limit must be greater than or equal to the Low Low Limit and less than the High Limit.

Move the

LO

marker up or down to set the

Low

value. As you move the marker, the

Low

value changes to match the value of the

LO

marker. The

LO

marker corresponds to the

Low Limit

value.

Enter the trigger point in Engineering Units. LLAlarm is set to 1 when the input signal moves below this limit. The Low Alarm Limit must be greater than or equal to the Low Low Limit and less than the High Limit.

Move the

LL

marker up or down to set the

Low Low

value. As you move the marker, the

Low Low

value changes to match the value of the

LL

marker. The

LL

marker corresponds to the

Low Low Limit

value.

Enter a deadband value in engineering units. Having a deadband value allows the process alarm status bits to remain set, even if the alarm condition disappears, as long as the channel data remains within plus or minus the deadband value of the process alarm.
