Program 448 - Burner requirement and 2 feed pump functions
Program 448:
Feed pump
A1
runs when:
S1
is greater than the threshold
min1
and
S1
is greater than
S2
by the difference
diff1
and
S2
has not exceeded the threshold
max1
.
The feed pump
A2
runs when:
S5
is greater than the threshold
min2
and
S5
is greater than
S3
by the difference
diff2
and
S3
has not exceeded the threshold
max2
.
Output
A3
switches on when
S5
falls below threshold
min3
.
Output
A3
switches off (dominant) when
S4
exceeds
max3
.
A1 = S1 > (S2 + diff1) & S1 > min1 & S2 < max1
A2 = S5 > (S3 + diff2) & S5 > min2 & S3 < max2
A3 (on) = S5 < min3
A3 (off) = S4 > max3
