This is best achieved by holding a steel rule as close to the feed tray as possible and measuring the ghost profile created by the movement of the tray see Fig 14 Note Some vibrating trays are fitted with a vibration motion label see below which will indicate clearly how much tray displacement occurs It completely negates the need to use a rule to measure the tray movement As the label vibrates with the tray the two diagonal lines will appear to converge The point of convergence can be read off the scale indicating precise tray displacement Fig 14 V2 Vibrator Unit running at 100 steel rule used to measure tray displacement left by shost image of tray when vibrating Step 4 If the amplitude of the tray measures approximately 4 5mm to 5 0mm then proceed to step 8 to ensure good linear vibration range Step 5 If the amplitude of the tray measures less than 4 5mm to 5 0mm loosen one of the lower vibrator spring M8 bolts It is important to loosen the bolt as the vibrator unit is running As the bolt is loosened a change in amplitude should be easily detected If no change is discernable gradually loosen a second bolt COTSWOLD MECHANICAL LTD VI Vibrator Vibrator Tuning Continued Step 6 If the tray amplitude increased when the bolts were slackened then the vibrator springs are too stiff The overall spring thickness needs to be decreased by either removing changing the s
