safety instructions
9.1.
Warning!
Risk of injury from improper operation!
Improper operation may result in injuries as well as
damage to the device and the area around it.
The operating personnel must know and have under-
•
stood the contents of the operating instructions.
Observe the safety instructions and intended use.
•
Only adequately trained personnel may operate the
•
equipment/the device.
operation of the lfc / lfm
9.2.
The LFC / LFM is operated by means of analogue standard
signals or field bus communication as well as binary inputs.
For operating and status displays 3 or 4 LEDs are also
used as binary outputs.
There is also a serial interface (RS232) via which a con-
nection to a PC can be established, e.g. using the “Mass
Flow Communicator” software.

Selecting the standard signals / Assigning
•
the binary inputs
The required configuration of the standard signal
type as well as the assignment of the binary inputs
can be specified on order placement or can be
configured via the “Mass Flow Communicator”
software (see also Chapter
11.1. Mass Flow Com-
municator (PC software).
LED assignment / Assigning binary outputs
•
The LED assignment (except the Power and the
Error LED) as well as the assignment of the binary
outputs can also be configured via the “Mass Flow
Communicator” PC software (see also Chapter
11.1. Mass Flow Communicator (PC software).

LFC:
Indicates that the actuating variable
of the proportional valve has almost
reached 100%. In practice this
usually means that the pressure on
the controller is not adequate to
reach the required flow-rate.
LFM:
Indicates that the actual value
has almost reached the nominal
flow-rate.
flashing The device is in an operating state
other than controlled operation or
the Autotune function.
