In-flight weight = in-flight weight + (dosing result – target weight) x correction coeff. The following condition must be
verified: In-flight weight low limit < in-flight weight < in-flight weight high limit. If this condition is not verified, the
in-flight weight value is not modified.
If ‘In-flight weight low limit’ and ‘In-flight weight high limit’ are equal to zero, limit condition has not to be verified.
12.2.8 Final stabilization time
This delay time corresponds to the minimum necessary duration for the stabilization of the weight before the
determination of the result and the control of tolerances.
When it is over, the ‘motion time out’ delay time begins. If the stability cannot be found within this duration, the
dosing result compared to the tolerances is equal to the last gross measurement value.
12.2.9 Tolerances
The dosing result is compared to 2 limit values in order to check that it is included within an acceptable range.
a high tolerance (tolerance +) or tolerance in excess:
if the difference | (target weight – dosing result) | > tolerance +
Where (target weight – dosing result) < 0, the ‘out of tolerances’ and ‘dosing failure’
outputs are activated.
a low tolerance (tolerance -) or tolerance in default:
if the difference |(target weight – dosing result)| > tolerance -
Where (target weight – dosing result) > 0, the ‘out of tolerances’ and ‘dosing failure’
outputs are activated. If the ‘use FF if out of low tolerance -’ is active, the fine feed is
restarted.
12.2.10 End of cycle waiting time
This delay time is triggered after the control of tolerances or after the end of the reloading phase if the reloading
mode is set to ‘at the end of the cycle’.
12.2.11 Effective end of the cycle
When the ‘end of cycle waiting time’ is over, an output assigned to the ‘cycle in progress’ function is disabled and the
statistic variables (number of cycles, average value, running total and standard deviation) are updated.
If the reloading mode is set to ‘at the end of the cycle’ and if the gross measurement is inferior to the ‘reloading min
level’, the reloading phase starts (cf. previous § .1.1) and the effective end of the cycle (‘cycle in progress’ inhibition
and statistic variables update) occurs when this phase is over.
12.3 Digital inputs utilization
12.3.1 Start cycle
If all the starting conditions are respected (cf. previous § .2.2), a rising or a falling edge (depending on the configured
logic) on this input, causes a new dosing cycle by unloading, else an error is reported by a ‘dosing failure’ output and
into a read-only diagnostic register.
12.3.2 Suspend current cycle
This input function has got two different effects:
If the ‘relaunch cycle if suspended’ option is inactive: this edge-active input causes the feeding cycle to be
stopped inhibiting the different outputs involved.
Else the cycle is suspended until a new request of starting the cycle that causes the cycle to continue from
its last step.
12.3.3 Stop cycle
This edge-active input causes the feeding cycle to be stopped inhibiting the different outputs involved.
