Fig. 4–6 B.I.T.E. control input terminals
Procedure:
1. Make sure that no load is applied on the transducer and that the activation of the B.I.T.E. function
does not endanger the application.
2. Activate the B.I.T.E. function.
3. Wait until the final voltage has settled (up to approximately 7 s if the LMU has been configured
with a 0,3 Hz filter).
3. Check the correct operation of the relays REL1 and/or REL2 (depending on the setting). Measure
the voltage U
O/P
and the current I
O/P
(by means of a measuring instrument connected to the
corresponding outputs).
4. Compare the measured signal to the calibrated signal (see installation).
5. Deactivate the B.I.T.E. function.
The signal obtained on the load monitoring outputs when the B.I.T.E. function is activated must
correspond to the signal after calibration.
