Digital Input I1; Diagnostic - MIB Flowmax 44i Operating Manual

Flowmax 44i
3.2.8 Digital Input I1 (only available with 8-pin plug)
Flowmax 44i has a digital input that is programmable for the following functions:
dosing input, set offset, creeping suppression inactive and reset counter. In
order to start a dosing process, 24V DC power is required. The status of the
dosing parameters or modifications can be done via user display or FlowCon.
Setting range: Off, Reset Counter, Dosing, Creeping Flow Off, Set Offset
Default setting: Off
The dosing input is locked so that a re-start is not possible during a running
dosing process.
Available input functions:
Set offset

0V
24V Rising edge:
0->24V
Set offset
run only in stationary medium
The input function "Set Offset" may only be used when there is no flow through
the meter. If an offset trim is done while liquid flow is present an offset drift will
cause measurement deviations. If the Flowmax shows an offset drift caused by
a wrong offset setting, run the function "Set Offset" or "Basic Trim" again with
filled flowmeter and no present flow.

3.2.9 Diagnostic

The sub menu "Diagnostic" shows the software/hardware version and other
helpful values for analysis. Actual values and the instrument´s present status are
important to analyze the measurement or failure by the manufacturer service.
Testing Flow
For commissioning of the process plant, a test flow can be adjusted. In that
case the flowmeter will behave as if the test flow is really flowing, even if the
flowmeter is empty. To start the simulation "Start" must be selected, "Stop" ends
the simulation.
When you restart the flowmeter, the test flow is stopped and the value deleted.
Setting range:
Pump Mode
This mode can be switched on and off via the menu.
With pulsating flow the flowmeter sets the display and analog filter on strong.
If the pulsating flow stops, the device behaves again as set.
