Range Alarms –
This menu allows you to enable and configure each of the 4 Range Alarms.
See Section 1 more information on this feature.
Each alarm has the following settings (see Figure 5.43) :
Enable:
[Disabled] Enables or Disables the Range Alarm
Latching:
[Disabled] Enables or Disables latching of the alarm. Non-latching alarms
return to a non-alarm state whenever the process input returns to a non-alarm level. Once
tripped, a latching alarm remains in an alarm state until the input returns to a non-alarm
level and is reset.
Source
: [Primary Variable] The Variable to be used as a source for the Range Alarm
Response:
[Warning] How to react if the specified condition occurs: Warning - Sends a
warning message to the HART Handheld/DTM, STZ HP display and sets a HART status
bit. Alarm - Sends the AO into fail mode and sends an alarm message to the HART
Handheld/DTM, STZ HP display. It also sets a (different) HART status bit.
Assertion
: [Out of Range] Indicates if the Range Alarm should detect if the source
variable goes Out of range, or goes In range.
Low
: [0.00] The defined lower limit of the Range Alarm
High
: [100.00] The defined upper limit of the Range Alarm
UnLatch Range Alarm:
Reset an actively latched range alarm provided that the input has
returned to a non-alarm level.
Note:
If a Range Alarm Response is set to Alarm, the AO will always perform a fail response
even if the Source Device Variable is not assigned to the PV.
