Programming The Relay Output - Burkert 8041 Manuel Utilisateur

- Release the push-button when the "full scale
calibration" feature is displayed, then you may:
♦
either press the push-button briefly to validate the
displayed feature. The magmeter is automatically
calibrated.
At the end of calibration, the red led goes off: the
magmeter has automatically returned to the flow
velocity Readout mode.
The teach-in full scale is saved by the electronics:
it is used by the magmeter as soon as switches 4
and 5 are set to ON.
♦
or press and hold the push-button to display
another feature.
♦
or wait for 10 s to return to the measured flow
velocity Readout mode, without validating the
displayed feature.
If the red led flashes 4 resp. 5 times rapidly,
the actual max. fluid velocity is resp. < 2 m/s
or > 10 m/s. Press the push-button briefly:
the sensor returns to flow velocity measure-
ment using the full scale of the previous
calibration.

3.6 PROGRAMMING THE RELAY OUTPUT

The user can program the following parameters for the operation of the sensor relay out-
put:
- The switching mode, either window or hysteresis
- The low switching threshold, in a percentage of the full scale
- The high switching threshold, in a percentage of the full scale
- The time-out before switching, from 0 to 100 s.
Whether the relay operating is Normally Open or Normally Closed is de-
termined by the connection of the relay to the terminals of the elec tron ic
board.
