1.06 CONTROL B1 Control input B1 and B2 (see Fct. 3.07 HARDWARE)

1.07 CONTROL B2 • OFF • EXT.RANGE (external range change)

Setting range: 5 - 80 PERCENT (= ratio of lower to upper range from

1:20 to 1:1.25. Value must be greater than that of Fct. 1.03 L.F. CUTOFF).

Fct. Text Description and settings

1.06 PULS B1 Pulse output B1 (see Fct. 3.07 HARDWARE)

→

FUNCT. P Select function for pulse output P

• OFF (switched off)

• 1 DIR. (1 flow direction)

• 2 DIR. (forward/reverse flow, F/R flow measurement)

Press key

↵

to transfer to subfunction

“SELECT P”.

→

SELECT P Select pulse type

• PULSE/VOL. (pulses per unit volume, flowrate)

• PULSE/TIME (pulses per unit time for 100% flowrate)

Press key

↵

to transfer to subfunction

“PULSWIDTH”.

→

PULSWIDTH Select pulse width

• 0.01 - 1.00 Sec (only for F

max

< 50 pulses/s)

• AUTO (automatic = 50% of the period duration

of the 100% output frequency)

• SYM. (symmetrical = pulse duty ratio 1:1 over total range)

Press key

↵

to transfer to subfunction

“VALUE P”.

→

VALUE P Set pulse value per unit volume (appears only when

“PULSE/VOL.” set under “SELECT P” above)

• xxxx PulS/m3 • xxxx PulS/Liter • xxxx PulS/US.Gal

• xxxx PulS/

user-defined unit, factory-set is “Liter” or “US M.Gal” (see Fct. 3.05)

Setting range

“

xxxx” is dependent on the pulse width and the

full-scale range: P

PULS. B1”.

→

VALUE P Set pulse value per unit time (appears only when

“

PULSE/TIME”

set under

“

SELECT P” above)

• xxxx PulSe/Sec (=Hz) • xxxx PulSe/min • xxxx PulSe/hr

• xxxx PulSe/user-defined unit, factory-set is “hr” or “day” (see Fct. 3.05)

Setting range

“

xxxx” is dependent on the pulse width, see above

• OVERFLOW I

• OVERFLOW P

}

• AUTO RANGE (automatic range change)

Setting range 5 - 80 PERCENT (= ratio of lower to upper range from

1:20 to 1:1.25. Value must be higher than that of Fct. 1.03 L.F. CUTOFF)

• TRIP POINT: XXX - YYY XXX > YYY N/O contact

0 - 150% 0 - 150% XXX < YYY N/C contact

Hysteresis ≥ 1%

(difference between XXX value and YYY value)

• EMPTY PIPE (signals that pipe is

“

empty”, only if option installed)
