Sidebar:
Default alarm times are set so that contact sets won’t alarm unless user configured.
It’s unlikely that you would set both alarms on any one contact set but the ability
to alarm both ON & OFF states gives you a lot of application flexibility.
ON Time Alarm:
If the pressure switch on your RO or sidestream filter shows high pressure for more than 30
minutes, you’d like to log an alarm.
If the flowswitch is ON between 6:00AM & 6:00PM
Is ON for more than 13 hours, either the flowswitch has faulted or operation has changed.
No Flow Alarm:
If you had a treatment system that runs 24/7 you’d want to alarm on a flowswitch
That has no flow since it indicates that the sensor or injection line is blocked
or inadvertently valved OFF.
