Diagnosable remotely - YES

Fixable remotely - YES (by customer)


This is likely to be a blocked chamber.


On digital machines - an error message will appear stating "Cylinder motion fault"

On non-digital machines - no product will come out of the outlet and the instrument will not cycle.


Solution (All machines except LV1):


This can usually be resolved by the customer with our instructions.


- Plug the reservoir using the "stopper".

- If desired and if practical, remove as much sample as possible from the reservoir and check valve, eg with a pipette.

- The above may not always be possible, eg, in the middle of a large batch. In this case, continue with using product, rather than solvent or cleaning agent.

- Disconnect the chamber or chamber set (IXC and APM).

- Reconnect the chamber or chamber set in the reverse orientation.

- Reattached the now empty reservoir.

- Check the instrument is primed.

- Run for 5-10 strokes at maxiumum pressure with cleaning agent, eg, IPA. Or with product if needed.

- If successful, product should flow out of the product outlet.

- If unsuccessful, continue to switch the orientation of chamber or chamber set, and attempting to cycle 5-10 strokes with cleaning agent. Eg, reversed orientation, normal orientation, reversed, etc.

- Eventually, the blockage will clear and product will flow out.

- Once cleared, ensure the chamber or chamber set is put back into the correct orientation.


Solution (LV1):


- Remove the cooling coil from the chamber.

- Remove the chamber.

- Reinstall the chamber "upside down" using the double-male back flush adapter from the toolkit, onto the pump head.

- NOTE: nothing attaches to the bottom of the chamber when back-flushing on an LV1. Product will just "spray" out of the open end.

- Place a beaker under the open chamber end.

- Run for 5-10 strokes at max pressure using a solvent/cleaning agent.

- If successful, product will spray out of the open chamber.

- If unsuccessful, keep reversing the chamber orientation and attempting to cycle at max pressure until the blockage is cleared.
