Scale parameters and functions of the belt scale
8.7 DR 5 Correction factors for material flow rate
SIWAREX WP241
Manual, 04/2014, A5E33713528A
91
The average belt load resulting on the scale from the material test is entered in % of the
nominal load.
Observe the percentage belt load during the test in SIWATOOL, on the touch panel or in the
SIMATIC, and subsequently enter the value.
The value to be entered must be larger than belt load factor 1.
Observe the belt load during the test in SIWATOOL, on the touch panel or in the SIMATIC,
and enter the value.
Correction factors 1 and 2
The correction factors have an effect on the material flow rate display and thus also on the
totalizer. They are calculated and entered following the material test. The amount recorded
in totalizer 4 is compared with the actual amount. The ratio between the actual amount and
the amount in totalizer 4 results in the correction factor.
Correction factor = (amount of material weighed previously or subsequently) / (amount
totalized by scale)
