Check speed input signal according to the flowchart in Figure 6-2. This examination should be
performed after the belt scale is powered on and has been running in normal speed. The speed signal
is in the form of pulses emitted by the speed sensor. The number of speed pulses can be learnt from
the Diagnostics menu of the 6105.

Check load cell input signal according to the flow chart in Figure 6-3 based on the following conditions:
·
Powered connected equipments
·
At normal belt speed
·
Empty load
·
Normal load cell input signal
Check that the weight indication displayed in Diagnostics menu of the 6105 integrator is between 1 and
16777216. The weight indication should be changed in the same direction as the sense of desired
result. If the weight indication is beyond the given range, there may be problems with load cell, wire
connection or CPU board. In this case, press RUN key to stop the examination of load cell input.
