Alarms view parameters
The
Alarms
view includes these parameters:Parameter | Description |
|---|---|
Disable All Alarms | Select to disable all alarms for a channel. |
Latch Process Alarms | Select to maintain an alarm-triggered condition for any of the process alarms, even after the condition ceases. The alarm unlatches only with an explicit message acknowledging the alarm. |
High High Limit | Sets the level of input to a channel that causes the device to set the High High alarm. The alarm remains until the input returns below this level unless it is within the deadband, or as long as the alarm is latched. |
High Limit | Sets the level of input to a channel that causes the device to trigger the High alarm. The alarm remains until the input returns below this level unless it is within the deadband or as long as the alarm is latched. |
Low Limit | Sets the level of input on a channel that causes the device to enable the Low alarm. The alarm remains until the input returns above this level unless it is within the deadband or as long as the alarm is latched. |
Low Low Limit | Sets the level of input to a channel that causes the device to indicate a Low Low alarm. The alarm remains until input returns above this level unless it is within the deadband or as long as the alarm is latched. |
Deadband | The value where an alarm, after it is set, does not disable as long as the input value remains within the deadband range of the alarm trigger point. This value in combination with the process alarms creates the range. |
Enable Rate Alarm Latching | When you enable this alarm, a Rate Alarm indication remains set even when the alarm condition goes away. The alarm unlatches only with an explicit message acknowledging the alarm. |
Rate Alarm Limit | Shows the value at which the rate alarm triggers. The rate alarm triggers if the rate of change between input samples for each channel exceeds this value for that channel. Set this alarm in engineering units per second, unless you have configured a sensor type for an RTD or thermocouple channel. In those cases, set the alarm in degrees per second. Degrees may be either Celsius or Fahrenheit, based upon the device configuration. |
Unlatch | Unlatches the adjacent alarm condition via a message sent to the device (active only if online). |
Unlatch All | Unlatches all alarms for the channel via a message sent to the device (active only if online). |
