Description and settings
1.05
CURRENT I
Current output I
→ FUNCT. I
Select function for current output I
• OFF (switched off)
• 1 DIR. (1 flow direction)
• 2 DIR. (forward/reverse flow, F/R flow measurement)
Press key
↵ , transfer to subfunction “RANGE I”;
→ RANGE I
Select measuring range
• 0 - 20 mA • 4 - 20 mA (fixed ranges)
• mA (user-defined range) I
0%
- I
100%
(Value I
0%
< I
100%
!) 0 - 16 mA 4 - 20 mA
To transfer to number setting, press key
→ !
Press key
↵ to transfer to subfunction “I ERROR“.
→ I ERROR
Select error value
• 22 mA • 0.0 to I

Press key
↵ to revert to Fct. 1.05 CURRENT. I.
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
• 100 HZ
• PULSE/VOL. (pulses per unit volume, flowrate)
• 1000 HZ
• PULSE/TIME (pulses per unit time for 100% flowrate)
Press key
↵ to transfer to subfunction “PULSWIDTH”.
With selection 100 HZ and 1000 HZ,
return to Fct.1.06 pulsoutput P (pulswidth 50% cyclic).
→ PULSWIDTH
Select pulse width
• 50 msec • 100 msec • 200 msec • 500 msec • 1 sec
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

100%
Press key
↵ to return to Fct.1.06 “PULS. OUTPUT 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” (see Fct. 3.05)
Setting range “xxxx” is dependent on the pulse width, see above
Press key
↵ to return to Fct.1.06 “PULS. OUTPUT P””.

• TOTAL. RESET (reset totalizers)
• ERROR. RESET(delete error messages)
Press
↵ key to return Fct. 1.08 “Control E”.
