This minimizes nuisance alarms by forcing the NGC-UIT3 to verify that the alarm condition continually exists over the selected period
of time before alarming.
Range: 10 to 59,940 seconds
Default: 900 seconds (15 minutes)
The 15 second option is for testing and demostration purposes. Choosing this option for normal use may cause
nuisance alarming since this option may not allow the NGC-UIT3 time to verify that the alarm conditions exist.
Fig. 3.13 Setup | Limit Cut-Out window
High Limit Cut-Out feature is triggered depending on Control and RTD Modes. The Table below indicates which RTD Modes will initiate
a High Limit Cut-Out for each Control Mode. If these RTDs are assigned to a Circuit and measure a temperature above the High Limit
Cut-Out threshold, the NGC-UIT3 generates an alarm and the relay output is turned off. If he High Limit temperature is below this
threshold minus the Deadband, the output is turned on.
