Hopper Configuration#

Problem	Possible Causes	Solutions
Control area cannot be defined	• Image not acquired • Wrong section	• Acquire test image • Access through Config Hopper X
AUTO does not calculate Mean and Std Dev correctly	• CAPTURE not performed • CAPTURE order reversed • Control area too small	• Perform empty CAPTURE then full CAPTURE • Repeat in the correct order • Enlarge the control area
TEST always GREEN (hopper never activates)	• Threshold too permissive • Full CAPTURE with too many components • Incorrect calculated Mean	• Repeat full CAPTURE with the correct minimum number • Verify that AUTO recalculates correctly • Manually adjust the threshold if necessary
TEST always RED (hopper always activates)	• Threshold too restrictive • Empty CAPTURE with components present	• Repeat empty CAPTURE with a completely clean area • Repeat AUTO
Vibration time does not produce the desired effect	• Value too low • Value too high • Variable hopper bowl level	• Start with 500ms • Increase by ±100ms to adjust the flow • CRITICAL: Maintain a constant load in the bowl
Hopper discharges at the wrong times	• Incorrect Steps • Hopper Controller hardware not configured correctly	• Recalculate Steps • Check the configuration specifications in the dedicated Hopper manual
