Control Philosophy
Control Concept – Single Filter
b. Automatic operation of Continuous mode:
Filter will switch to continuous flushing if there were 3 consecutive flush cycles with interval shorter
than 5 minutes.
The filter will stay in continuous flushing for 20 min. or until RESET. Afterwards will turn back to
normal operation.
Filter will switch to Clogging Fault (PD Time Fault) if a DP signal for duration of 5 min is received
while in continuous mode.
Note: All timers and counters should be programmable per case.
HMI Considerations:
1. The following Information should be displayed on the HMI:
a. Current Inlet Pressure (PT1) - if applicable
b. Current DP across the Filter
c. Current Status: Filtering; Flushing; Continuous Flushing; Fault
d. Time from Last Flush and time to the next flush (by time)
e. Cause of last flushing – DP / Time / Test / Remote
f. Detail of Fault (Limit Switch; Motor Time out….)
g. Flush Counter
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. Time in Continuous - Manual Minutes 0 - 240 60
h. Time in Continuous – Auto. Minutes 0 - 240 20
i. No. of consecutive cycles Cycles 1 - 10 3
j. Interval for consecutive cycles Minutes 0 - 10 5
