SelfTested = True
Stop
File Explanation:
This program runs a weekly self-test on the dedicated controllers in the
system. In this example, the SCX920S smoke damper controller,
SMKDMPRS, and the TCX853 stairwell fan controller, AHU3, are the
only dedicated controllers.
Assumming the system is not performing smoke control, this program is
run by the MAIN program at Midnight on Saturdays.
The sequence of operations are as follows:
• Clear all self-test failure numerics (".ST.Fail").
• First the smoke dampers are tested in the Closed position by setting
SMKDMPRS DefaultDmprPosn = ON. The program then waits for
a period of time equal to MaxDamperTime + 5 seconds. If a ".Fail"
numeric is set by the PlantFaultCheck function, then it's
corresponding self-test failure numeric (".ST.Fail") is turned ON.
Turning on this numeric causes the self-test failure to be latched. The
only way to clear it is to turn ON the Master Key and press CLEAR
FAULTS.
• Next the smoke dampers are tested in the Open position by setting
SMKDMPRS DefaultDmprPosn = OFF. Again the program waits
for MaxDamperTime + 5 and sets the self-test failure numeric if it's
corresponding failure numeric is turned ON by PlantFaultCheck.
• Next the stairwell fan is tested in the ON state by setting AHU3
DefaultFanPosn = ON. The program waits for MaxFanTime + 5
and sets the self-test failure numeric if it's corresponding failure
numeric is turned ON by PlantFaultCheck.
• Next the stairwell fan is tested in the OFF state by setting AHU3
DefaultFanPosn = OFF. The program waits for MaxFanTime + 5
and sets the self-test failure numeric if it's corresponding failure
numeric is turned ON by PlantFaultCheck.
• If there are any self-test failures, turn ON the Status4 indicator.
• Print "Weekly Self Test Complete" and the Time to the Message
window.
• Set the numeric SelfTested to TRUE, therefore the system will not
perform another self-test until the following week.
