VEGAPULS 64 and 81 69
Adjustment steps with the signal con-
ditioning instrument
You adjust the signal conditioning instrument
and the sensor with the six keys on the signal
conditioning instrument (–; +; ← ; → ; ESC; OK).
The basic set-up steps:
- First create a new measurement loop with
the menu “ Configuration / Configuration
measurement loop“
- Then co-ordinate the sensor to an input of
the signal conditioning instrument in the
menu “ Configuration / Configuration inputs /
Input no.…“
- In the submenu “Sensor optimization“ out of
the menu “Configuration / Configuration
inputs“ you then carry out the configuration
and parameter adjustment of the sensor.
Hence the set-up of the radar sensor is carried
out. In the main menu “Parameter adjustment“
and in the menu “Configuration / Configuration
outputs“ you choose how the sensor values
should be processed and provided. E.g. you
carry out the adjustment, the scaling, the
parameter adjustment, the current outputs or
the adjustment of the relay functions.
First set-up with the signal condition-
ing instrument
After you have connected the radar sensor (s)
with a screened two-wire cable to the signal
conditioning instrument VEGAMET 514 V or
515 V switch on the power supply for the sig-
nal conditioning instrument. The signal condi-
tioning instrument powers then the sensor (s)
with energy.
Types C, D and E of VEGAPULS 81 series are
powered separately. Connect the sensors like
the signal conditioning instrument to the power
supply.
Fault signals
Normally you get fault signals. This is normal
for the first set-up. Hence carry out an instru-
ment reset first before you create a measure-
ment loop and you carry out the parameter
adjustment.
Set-up: Adjustment with signal conditioning instrument
Reset
Carry out a reset first to provide a defined
instrument condition. Proceed acc. to the
following steps: Push the left key until in the
display (right) the appropriate indication ap-
pears. “OK…OK“ means that you have to push
“OK“ until the requested indication appears in
the display.
Key: Display:
OK…OK The fault signal disappears. First the
measurement loop (TAG) without
measured value is indicated.
OK Then parameter TAG1…3 appears.
Note:
If no adjustment is made for appr. 15 seconds,
the indication jumps back to the stage of the
measured value indication or to the fault sig-
nal. Then push again “ OK“ until the fault signal
extinguishes.

The indication flashes and all measurement
loops are reset to linked application. The menu
“ Linked application“ appears again.
If you want to carry out a differential measure-
ment with two sensors, the following adjust-
ments are necessary. Continue your adjust-
ment under “ Quit reset menu“. However if you
need single measurements, continue with the
adjustment.
