Connecting The Device With 0-10 V And 4-20 Ma Output Signal; Operating The Inline Amplifier/Zeroing The Measurement Chain - HBK U9C Montageanleitung

8.2.2 Connecting the device with 0-10 V and 4-20 mA output signal
The device is connected via a M12 plug on the front of the inline amplifier. The assign­
ment is set out in the following table. The supply voltage must be within the specified
range (19 V ... 30 V).

The cable connecting the inline amplifier to the next link in the measurement chain must
not exceed 30 m in length.
8.2.3

Operating the inline amplifier/zeroing the measurement chain

The measurement starts as soon as the sensor is connected to a supply voltage and the
output of the amplifier is connected to the next link in the measurement chain.
If you apply a voltage > 10 V to the "Zero" input, a one-off zeroing is performed. After this
zeroing, the device continues to measure, even if you apply a voltage above 10 V to the
input.
To trigger a new zeroing operation, the input must first be set to 0 V and then be reset by
applying a voltage of over 10 V.
Notice
Please note that you can zero the measurement chain with any force applied. If an initial
load is already acting on the force transducer, it is essential to consider it, otherwise the
force transducer may be overloaded.
The zero point is not permanently stored in the device. If you have disconnected the
measurement chain from the supply voltage, we recommend zeroing again.
