3.1.10 Sensor: analog standard signals
Measuring is carried out by a sensor with a standardized process signal 0-10 V. The
input is selected in menu 'Configuration'.
Nominal force or nomi-
nal distance:
Adjustable via the menu
A/D converter:
12 bit = 4096 steps (for EPW 400.x02.1x)
16 bit = 65536 steps (for EPW 400.x02.0x)
Nominal load of reso-
lution:
Steps see A/D converter, 1 step (bit) = nominal load /
steps
Accuracy of measure-
ment:
1%
Max. sampling rate:
2000 Hz (0.5 ms)
3.1.11 Sensor: supply voltage
Auxiliary voltage:
24 V ± 5%, max. 100 mA
Reference voltage:
10 V ± 1% nominal signal: 0 – 10 V
Adjustment value
The entries 'Nominal force' or 'Nominal distance' must not be
changed without the agreement of the manufacturer.
3.1.12 Screw sensor with standard signal output
Auxiliary voltage:
24 V ± 5%, max. 100 mA
Nominal signal:
0 – 10 V
Tare signal:
0 V = zero adjustment, > 9 V = measuring mode
Adjustment value
The entry 'Nominal force' must not be changed without the agree-
ment of the manufacturer.
Tightening torque: 14 Nm
Zero adjustment before each work cycle
With some types of force transducers or measurement amplifiers
with tare function, a decrease of the measuring accuracy is possible
after a certain period of time depending on the process. In order to
ensure repeating accuracy, a zero adjustment should be carried out
before each work cycle or at regular time intervals (e.g. for ZKN
model force transducers after approx. 10 minutes).
