Optional LCD display in cover
:
2 x 16-digit, character height 5.5 mm.
Display line 1
: instantaneous value velocity or flow rate.
Display line 2
: 'quantity counter' or 'error code'.
Configuration (see Fig. 2, A3.2.6) via 2 jumper wrap connectors ST1 and ST2
Display line 1
:
ST1 = m/s
and ST2 = any:
velocity in (N)m/s *
ST1 = m³/h (lt/h)
and ST2 = A:
flow rate in (N)m³/h
ST1 = m³/h (lt/h)
and ST2 = B:
flow rate in (N)lt/h **
* standard values (N) only when parameter 'switching v/NV' =1 (see under A5)
** only when diameter Di < 75.0 mm, otherwise display in (N)m³/h
Display line 2
:
Quantity counter in m³ with 0 ... 3 decimal places
(see under A5: parameter 'switching pulse m³(cbm) / l (litre)' and
parameter 'm³ (cbm) / l (litre) per pulse' and
parameter 'decimal places quantity display')
with error
: error 01 = parameter error
error 02 = sensor error
(see A10: Troubleshooting)
Reset button in cover: see Fig. 2: A3.2.6
Reset the quantity counter by pressing the reset button for more than 3 seconds.
A5 Settings
The following setting parameters can be read using the PC software UCOM and are also alterable.
The customer-specific settings are shown on the parameter print-out, which is included in the
documents.
Please find operation instructions PC software UCOM in document U385.
A6 Initial Operation
(A3.2.2 Pay attention to power supply)
(A3.2.3 Pay attention to analog output)
After connecting the supply voltage the green LED lights up, the yellow LED is switched off.
No flow at sensor: the green LED is permanently on, the analog output supplies a value of 4 mA at flow
output or at voltage output a value of 0 V.
Flow at sensor: the green LED flashes, the analog output supplies an analog value other than the given
values of the zero flow conditions (see above).
