o Running wheel:
The running wheel is placed onto the conveyor belt.
o Drive shaft:
The tachometer is connected with a shaft via a coupling.
Forward feed per revolution
(only when tacho drive with motor shaft has been selected)
Forward feed = distance of conveyor belt at one tachometer revo-
lution.
Input in mm.
Select unit [t]/[kg]/[kg/m]
Select the unit.
o [t]/[kg]
If t or kg is selected, the measurement is carried out in t/h or
kg/h. For calibration, you have to enter a comparative weight in t
or kg.
o [kg/m]
If kg/m is selected, the measurement is carried out in t/h.
For calibration, however, you have to determined a comparative
weight in kg/m.
See also "Calibration in kg/m" and "Static Calibration" on page 72.
Error mode
Select if the measurement is to be aborted or continued if an error
occurs. If you select „continue“, the error message is only dis-
played, but the system continues measuring. Push < enter > to
clear the error display.
Curr. outp error:
o Hold
If any error is detected and the measurement is interrupted be-
cause of the error, the current output holds the last current value.
o Value
If any error is detected and the measurement is interrupted be-
cause of the error, the current output switches over to a predefined
current value.
Load in case of stop
o Hold
If the measurement is stopped externally or via the "run" button,
the display and the current output will hold the last value.
o Value
If the measurement is stopped externally or via the "run" button,
the conveying capacity on the display switches over to 0 t/h and
the current output to 0 or 4mA.
