Hardware problems

Locate your problem in the table and try the solution. If the problem persists after you try the solutions, contact Automation Solutions Technical Support.

 

Problem	Possible cause	Solution
The Vertical Pipetting Station does not turn on.	Your lab does not meet the electrical requirements.	Make sure your lab meets the electrical requirements.
	The power cord is damaged or is not connected to the power source.	Ensure the power cord is in good condition and is connected to the Vertical Pipetting Station and the power source.
	The Vertical Pipetting Station fuse is bad.	Replace the fuse. A bad fuse could be indicative of other problems. If the fuse blows again, contact Automation Solutions Technical Support.
A hissing sound is present when the air is turned on and nothing is moving.	A leak is present in the air connections or inside the device.	Check the air tubing and the connections on the Vertical Pipetting Station rear panel and at the source for leaks.
The Vertical Pipetting Station does not dispense accurately on a particular shelf.	The shelf is loose, or the teachpoint is incorrect.	Gently wiggle the shelf to check the tightness. Verify the teachpoint.
	The pipette head barrels or o-rings are bad.	Contact Automation Solutions Technical Support.
The pipette head will not disengage from the head mount.	The pipette head is locked.	Verify that the head retainer pins are retracted (96- or 384-channel head), or the head lock is in the unlocked position (8- or 16-channel head).
Liquid fails to pump into or drain from an autofilling reservoir.	The Pump Module tubing has deteriorated or is not connected properly.	Inspect the tubing and the connections, and replace, if necessary.
The liquid in the wash trays or reservoirs is overflowing causing flooding.	The tubing is kinked or the Weigh Shelf might require recalibration.	Inspect the tubing. If necessary, recalibrate the Weigh Shelf.
During a tips-off operation, the tips remain on the pipette barrels.	Static electricity buildup is causing the tips to stick on the barrels.	Edit the profile to include a tip-touch during the tips-off task.
During initialization, a z‑position timeout occurs.	The z‑motor brake is sticking.	Contact Automation Solutions Technical Support.
