Control Philosophy
Control Concept – Multiple System
HMI considerations:
1.
The following Information should be displayed on the HMI:
a. Current Inlet Pressure (PT1) - if applicable
b. Current DP across the entire Filtration System
c. Current System Status: Filtering; Flushing; Continuous Flushing; Alarm; Fault
d. Current Status of each filter unit: Filtering; Flushing; Continuous Flushing; Fault
e. Time from Last Flush and time to the next flush (by time)
f. Cause of last flushing – DP / Time / Test / Remote
g. Detail of Fault (Filter No., Limit Switch; Motor Time out….)
h. Flush Counter
i. Number of filters flushing together.
2. Parameters setting
The following parameters values should be programmable via the HMI:
•
Operating Method: Continuous / Time &DP / DP only
•
Rest Flushing counter
Parameter Units Range Default Comments
a. DP Set point: Bar(d) / psi (d) 0.1 – 0.7 / 1.5 - 10 0.5 / 7.0
b. Minimum Inlet pressure: Bar(g) / psi (g) 1.0 – 10.0 / 15 - 150 2.0 / 30
c. Interval for flushing by time: Minutes 1 – 1440 480 0 = Never
d. Time in HDP before Fault: Minutes 1 – 60 5
e. Delay before open XV1: Seconds 0 – 12 1
f. Delay before Start Motor: Seconds 0 – 10 3
g. Number of filter units flushing
together:
Filter Units 1 - 4 2 Depends on system
size
h. Time in Continuous - Manual Minutes 0 - 240 60
i. Time in Continuous – Auto. Minutes 0 - 240 20
j. No. of consecutive cycles Cycles 1 - 10 3
k. Interval for consecutive cycles Minutes 0 - 10 5
