Set Up Maximum Pressure Alarms and Time Delays
The QDC module continuously monitors the system pressure input. When
it detects that the process input equals or exceeds a preset alarm setpoint,
the QDC module sets an alarm bit. A setpoint of zero disables the
associated alarm.
To guard against nuisance alarms caused by noise spikes or pressure
transients, you can set a time delay so the QDC module must monitor
continuous excessive pressure for an amount of time before setting the
high pressure alarm. A setpoint of zero disables this delay.
Configure the QDC module for the system pressure alarm as follows:
1. Determine these values:
pressure-alarm setpoint
time-delay setpoint
2. Record non-zero setpoints on Worksheet 3-G for the pressure alarm
and time delay.
3. Download them to the QDC module using the procedures presented
earlier in this chapter.
