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

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
