6.4.2 Alarm delay (P004)
For relay, alarm delay (P004) outputs Q2 and Q4 from probe B input.
Note
Once an alarm delay is programmed, no input is required to activate.
Enter a relay output delay in seconds (0-399). The delay avoids false alarms in conditions
which can go in and out of desired range setpoint frequently.
When value = > 0 then output relays are held maintained (Hi) for the set time period to allow
system to achieve process speed
Note
Typically used for a Slow Speed process, but will work with standard operating functions as
well.
