8.3 Menu 1.1 Basic parameters
Menu 1.1 “Basic parameters” contains the most important settings for commissioning a
scale. Changes to those parameters can only be done when switching to “service mode”.
The system is requesting to do in case such changes shall be done.
1.1.1 Basic parameters 1 von 2
Scale name
You can select any name, but it may not exceed 12 characters. You can
enter any designation.
Unit of belt load
and speed
When setting parameters for the first time you must select between met-
ric and imperial systems.
The following units can be selected for the belt load:
0 – kg/m + m/s (metric)
1 – lbs/foot + foot/s (imperial)
2 – lbs/foot + foot/min (imperial)
With the kg/m unit, the material flow rate can be specified in t/h or kg/h.
With the lbs/foot unit, the material flow rate can be specified in T/h, TL/h
or lbs/h.
Unit of flow rate
Folgende Einheiten für die Förderstärke können gewählt werden:
The following units can be selected for the material flow rate:
0 – t/h (metric)
1 – kg/h (metric)
2 – T/h (imperial)
3 – TL/h (imperial)
4 – lbs/h (imperial)
Resolution of belt
load
The resolution for the weight measurement and the belt load per length
unit can be defined in accordance with the standard EN 45501 (1*10**k,
2*10**k, 5*10**k]; k: -3 … 2) from 0.0001 to 50.
Resolution of flow
rate / totalizers
S2…S6
The resolution for the material flow rate and totalizers 2 to 6 can be de-
fined in accordance with the standard EN 45501 (1*10**k, 2*10**k,
5*10**k]; k: -3 … 2) from 0.0001 to 50.
Resolution of mas-
ter totalizer
The resolution for the master totalizer (cannot be deleted) can be de-
fined in accordance with the standard EN 45501 (1*10**k, 2*10**k,
5*10**k]; k: -3 … 2) from 0.0001 to 50.
Design flow rate
(Qmax)
The design flow rate is entered during initial commissioning. It can be
obtained from the data sheet for the belt scale. It corresponds to the
maximum material flow rate (100%) for which the conveyor belt is de-
signed.
The % values for the material flow rate limits refer to the rated flow rate.
Weigh length
In the case of a scale with a roller station, the weigh length corresponds
to half the distance from the roller station to the adjacent rollers on the
left and right which are located upstream and downstream of the roller
station.
With two or more roller stations, the distance between the roller stations
is added to this.
