Shunt signal (Option 3, Code SU2)

The T10FH torque flange delivers a shunt signal that can be switched at the
amplifier end for measurement chains with HBM components. The measure
ment flange generates a shunt signal of about 50% of the nominal (rated)
torque. The precise value is specified on the identification plate. Adjust the
amplifier output signal to the shunt signal supplied by the connected torque
flange to adapt the amplifier to the measurement flange. To obtain stable con
ditions, the shunt signal should only be activated once the transducer has
been warming up for 15 minutes.
NOTE
The transducer should not be under load when the shunt signal is being mea
sured, as the signal is applied additively.
CAUTION
To maintain measurement accuracy, the shunt signal should be con
nected for no more than 5 minutes. A similar period is then needed as a
cooling phase before triggering the shunt signal again.

7.1 Shunt signal

Applying a separated extra−low voltage of 5 V to pin 6 (+) and 7 ( ) on plug 1
or 3 triggers the calibration signal.
The nominal (rated) voltage for triggering the shunt signal is 5V (triggered
when U>2.7 V). The trigger voltage is electrically isolated from the supply volt
age and the measurement voltage. The maximum permissible voltage is 30 V
When voltages are less than 0.7 V, the torque flange is in measuring mode.
Current consumption at nominal (rated) voltage is approx. 2 mA and at maxi
mum voltage is approx. 22 mA.
NOTE
In the case of HBM system solutions, the amplifier triggers the shunt
signal.
