2 Make instrument operational on the bus
(give it a FLOW-BUS node-address)
If rotary switches are present on the side of the instrument, please see paragraph 2.6.4.
Complete FLOW-BUS systems are already factory configured and tested and will be directly operational on
the bus. However, changes in the system or adding new modules could need new (free) addresses on the
FLOW-BUS.
Watch the LED’s on top of the instrument when the instrument powers-up.
If the green LED is burning continuously and the red LED is off, everything is o.k. the instrument is
operational on the bus.
If the red LED is blinking slowly, the FLOW-BUS address is already occupied. In that case: press the micro
push-button and release it after 2 seconds. Now the instrument is operational on the bus (pressing the push-
button for 1 to 4 seconds will activate the auto install function, the instrument will install itself to a free node-
address).

Make link to operator module
(search module on the bus with the operator).
You can search for this instrument, looking for type and serial number.
a With E-7000 module for digital instruments:
Go to the FLOW-BUS menu and select “OPERATE INSTR.”.
Use <- or -> keys to search the bus for the wanted instrument.
Instruments can be identified by their serial number. Also both LED’s on the instrument will blink turn by
turn (wink) for some seconds.
When found, press middle-key (enter) to make connection for operation.
b With
PC-software
application:
When you use FLOWDDE or FLOWBUS.DLL (for Windows applications) all
modules connected to FLOW-BUS will be recognised automatically. They will be assigned to a channel
for operation. (see FLOW-DDE configuration menu)
Other programs will have to get procedures for reading identification of instruments. For details, see
FLOW-BUS software documentation.
Send a setpoint to the instrument and check the measured value
Let the instrument warm-up for 30 minutes for best accuracy
Your Mass Flow Meter/Controller is now ready for operation.
