The following examples detail the use of the 4010’s newer Custom Control
features.
M1-1 is a TrueAlarm Photo sensor. Customer wants normal 2.5% sensitivity
during working hours (7am – 6pm) and higher sensitivity (1.0%) at night. (A11
is current hour analog pseudo point.)
Equation 1:
IN:
A11 GREATER THAN 7 (7 is 7am)
OUT:
SET THRESHOLD M1-1 LEVEL 5 (level 5 is
2.5% obscuration)
END:
Equation 2:
IN:
A11 GREATER THAN 18 (18 is 6pm)
OUT:
SET THRESHOLD M1-1 LEVEL 2 (level 2 is 1.0%
obscuration)
END:
A customer wants a supervisory alert when an impending freeze is detected by a
TrueAlarm heat sensor. M1-1 is a HEAT sensor programmed with the
UTILITY point type. P75 is a user defined digital point with the
SUPERVISORY point type.
IN:
M1-1 LESS THAN 38 (38 is degrees F)
OUT:
TRACK ON P75 PRI=9,9
END:
A customer only wants the city circuit’s alarm output to activate when a
waterflow alarm occurs. In this example, L25 is a user-created list of all
Waterflow monitor points.
IN:
L25 ALARM
OUT:
TRACK ON P60 PRI=7,7 (Use priority greater than
9 to control this point)
