A4 station address
A4
station address
Appropriate interface for Profibus / FF / Modbus devices.
A5 digital outputs
A5
digital outputs
Valid for all pulse outputs (terminals A, B and/or D) and counter 1.
A5.1
measurement
1) Select measurement: volume flow / mass flow
2) Use for all outputs? (also use this setting for Fct. A5.2...A5.4!)
Setting: no (only for pulse output D) / yes (for all digital outputs)
A5.2
pulse value unit
Selection of the unit from a list, depending on the measurement.
A5.3
value p. pulse
1) Setting for pulse output D (volume or mass value per pulse)
Setting: xxx.xxx in l/s or kg/s
2) Use for all outputs? Make setting, see Fct. A5.1 above!
A5.4
low flow cutoff
1) Setting for pulse output D (sets output value to "0")
Setting: x.xxx
±
x.xxx% (range: 0.0
…
20%)
(1st value = switching point / 2nd value = hysteresis),
condition: 2nd value
≤
1st value
2) Use for all outputs? Make setting, see Fct. A5.1 above!
A6 GDC IR interface
A6
GDC IR interface
After this function has been called up an optical GDC adapter can be
connected to the LCD display. If about 60 seconds pass without a connection
being established or after the adapter is removed, then the function is exited
and the optical keys are active once again.
break (exit function without connection)
activate (the IR interface (adapter) and interrupt the optical keys)
A7 process input
A7.1
device serial no.
Serial no. of the system.
A7.2
zero calibration
Display of current zero calibration value.
Query: calibrate zero?
Setting: break (return with
^
) / standard (factory setting) /
manual (display last value, set new value,
range: -1.00
…
+1 m/s) /
automatic (shows the current value as the new zero calibration value)
A7.3
size
Select from size table; range: DN2.5...3000 mm / 1/10...120"
A7.4
GK
Depending on the selection in Fct. A7.4 / A7.5, the Fct. C1.1.0, 5 or 6 appears.
Set value acc. to nameplate; range: 0.5
…
12 (20)
A7.5
GKL
A7.6
coil resistance Rsp
Field coil resistance at 20
°
C; range: 10.00...220
Ω
A7.7
calib. coil temp.
The coil temperature is derived from the coil resistance at the reference
temperature.
Set coil temperature:
break (return with
^
key)
Standard (= 20
°
C)
automatic (set current temperature); range: -40.0
…
+200
°
C
Set coil resistance:
break (return with
^
key)
Standard (= setting of Fct. C1.1.7)
automatic (= calibration with the current resistance)
A7.8
target conduct.
Reference value for on-site calibration; range: 1.000...9999
