6-18 Setup and Configuration
Valve Offsets
This screen-prompted routine identifies and records a Safe-Z Height for dispensing head
travel, the XYZ locations of the Purge Station and Weigh Station, Needle and the substrate
height. It also calibrates the camera-to-needle and needle-to-probe offsets.
This routine is performed when the dispensing system is initially installed and configured.
Those values and settings are recorded. You can run this routine again at any time to insure
dispensing accuracy or reflect hardware or changes. You can choose to use pre-recorded
values during the routine.
Definitely perform a Valve Offsets if any of the following events occur:
• initial system setup (re-installation of dispensing system)
• re-initialization or re-installation of system software
• software update
• valve change (not syringe)
• camera change or location adjustment
• service station (Purge, Weigh Stations) change or location adjustment
• Needle Sensor change or location adjustment
• Height Sensor change or location adjustment
• Changing from Calculate Master Offsets
?NOTE Calculate Master Offsets and Valve Offsets both perform all of the
necessary setup functions. The main difference between the two
procedures is that Valve Offsets allows you to perform the entire process
one step at a time. Calculate Master Offsets walks through the entire
process from start to finish.
