Introduction
Product description
The signal conditioning instrument VEGAMET
407 Z is used for manifold applications for
continuous level measurement.
VEGAMET 407 Z is integrated in a series 400
plastic housing.
A sensor (pressure transmitter or capacitive measuring electrode) can be connected via a two-core
line to the signal conditioning instrument. This line
is responsible for the power supply from the signal
conditioning instrument to the sensor. The measuring currents are transmitted analog from the sensor
to the signal conditioning instrument and evaluated.
The signal conditioning instrument can be
calibrated and adapted to the measurement by the
user via parameter adjustment.
These adjustments are made without additional
facilities and tools via a 5-button keyboard
integrated on the front panel.

Empty, full adjustment in %
The measurement range for level 0 % and 100 % is
defined via the adjustment procedure.
When the vessel is partly filled or emptied the programming is as described on the right, however
with previously determined %-values.
The min. measuring range must correspond to a
current
∆ of > 300 µA.
Example
Full
• fill vessel
adjustment • select mode in MODEFIELD
• program level 100 % in
PARAMETER FIELD
• then store with STO
Empty • empty vessel
adjustment • select mode in MODEFIELD
• program level 0 % in
PARAMETER FIELD
• then store with STO
The empty and full adjustments may be performed
in any order.

Empty, full adjustment in mA
The measuring current values are coordinated to
the levels 0 % and 100 % with the adjustment.
The measuring currents are experience values or
can be taken from the attached test certificate.
The procedure is used:
- for adjustment without rate of product level
change
- for correction of previous adjustments (alarm E3
or E4)
- for adjustment without connection of a capacitive
electrode or a pressure transmitter (alarm E2)
Example
Full • select mode in MODEFIELD

simultaneously (data input for mA)

• then store with STO
Empty • select mode in MODEFIELD
adjustment • push button + and button MOD

• program 5,28 mA in

Integration time
Application
- Where the product surface is agitated the system
outputs may be stabilized by adjusting the integration time.
Important notes:
The integration time depends on the filling and
emptying period of the vessel, i.e. integration time
≤ filling / emptying time. Mis-adjustment of the
integration time may degrade output sensitivity.
Definitions
- range = 0 … 199 sec.
- (0 … 199 secs. corresponds to the definition in
sec.)
At 200 sec. effects a time period, the actual value
is approx. 45 minutes.
- settings > 200 sec. are automatically limited to
the max. value 200 sec.
Example
- integration time of e.g. 15 sec.
• select mode t in MODEFIELD
• program 15 sec. in PARAMETER FIELD
• then store with STO
Example..............to activate the simulation ……… • select mode SIM in MODEFIELD
• activate the simulation with button MOD
• increase or reduce the output with button + or
button –
t
Simulation mode
In the simulation mode it is possible to test the
measuring system over the whole measuring range
independent of the process.
Button + increases and
button – reduces
all output values.
The longer the simulation button + and – are
pressed the greater the rate of change.
Integration time is ignored during the simulation
sequence.
