7.3 Pin assignment for the connectors
The pin assignments for the connectors are detailed on the following pages.
The transducer outputs the measurements as an electrically isolated signal. The
ground potentials should not be directly bridged at the transducer, as this could
lead to incorrect measurements, depending on the length of the cable to the
power supply and display unit. Instead, they can be bridged at the power supply
and display unit, if necessary.
7.4 Control activation
The “control activation” is used to test the transducer. This emits its maximum
signal of e.g. 10 V and 15 kHz (with right-hand load). The control level is 4.5 V up
to the supply voltage; the reference ground point is the supply ground.
Attention: Note the tare!
7.5 Extension cables
Extension cables must be shielded and have low capacitance. We recommend
you use our cable, as it meets these requirements. Pay particular attention to the
connectors and ensure good insulation when using cable extensions. The cable
cross-section should be sufficiently large to ensure adequate power reaches the
transducer. There is no need to recalibrate the transducer when extending the
cable.
7.6 The power supply
The torque transducer is fitted with a universal voltage input for the voltage ran-
ge 10 V - 28.8 V. If the voltage goes above 28.8 V, the internal suppressor circuit
is activated and the power supply is shorted.
