• None : analog outputs have no function.
• Gross measurement : analog outputs can be assigned to gross measurement copy. Maximal level value is
related to Maximum Capacity parameter and works in mono-quadrant functioning. Bi-quadrant option can
only be applied to gross measurement copy. When this option is activated, the lowest value of current and
voltage levels corresponds to -MC and the highest value to +MC.
• Net measurement : analog outputs can be assigned to net measurement copy. Maximal value is related to
Maximum Capacity parameter and works in mono-quadrant functioning only. The highest value of current
and voltage levels corresponds to +MC in only one quadrant.
• Level on request : analog outputs are driven by master requests through the external value to control
analog output variable (in 0.01% of the full scale of current or voltage analog outputs).
• Flow rate control output : PID controller output data (activated or not) drives current or voltage outputs
generally coupled to the extraction device. Data is expressed in 0.01% of the high value of current or
voltage analog outputs. Maximal level output value corresponds to the maximal flowrate (see § flow rate
calibration).
• Instant flow rate : analog outputs can be assigned to instant flow rate copy. Maximal level output value
corresponds to the maximal flowrate (see § flow rate calibration).
• Average flow rate : analog outputs can be assigned to average flow rate copy. Maximal level output value
corresponds to the maximal flowrate (see § flow rate calibration).
• Average belt speed : analog outputs can be assigned to average belt speed copy. Maximal level output value
corresponds to the maximal belt speed (see § BELT OPERATING MODES).
When analog output is assigned to “Gross measurement”, “Net measurement”, “Instant flow rate” or “Average flow
rate” its value jumps to a special error value when the internal alarm flag described in “Weighing diagnosis” § in the
MEASUREMENT AND STATUS § is activated. This allows to warn about defection of the measurement chain.
