16. Clogged Obstructed Valve It is possible for the valve inlet to become clogged with particles from the fluid being used Ifa valve becomes clogged then fluid can no longer be pulled into a pump This can be detected by watching the pressure in the pump cylinder as the piston retracts The pressure should not drop more than 1 2 PSI If it drops more than this the fluid may not be getting into the pump cylinder due a clogged inlet tube or valve The outlet side of the valve is unlikely to clog due to the fact that the pump can generate high enough pressures to push most particles out of the valve It may be possible to clear a clog on the inlet side by using the pump to push the particles out of the inlet It would be advisable to clean all tubing and components thoroughly if a clog has been encountered so that this problem does not reoccur 9 4 7 7 Valve Leaks Fluid When Closed There is a possibility that the valve will not fully close and fluid can leak across the closed valve If this occurs the valve will not hold pressure If you pressurize a pump and it is not holding pressure fluid may be leaking out of a seal or it could be leaking out across the valve One way to check if a valve is leaking fluid is to swap valve A and valve B Refer to the Valve User Manual for maintenance and repair instructions 9 5 Software Updates The operation of the QX Series Pump is controlled by two separate software programs Pump Works which is stored on the

49. 9 2 1 Immediate Errors An Immediate Error is generated in response to a command sent by the user This is generally the result of a user asking the pump to do something that is not permitted An example is trying to open or close a valve or change the operating mode of a pump cylinder that is currently running A dialog box immediately appears on the window with an error message Chapter 9 QX SERIES PUMP OPERATING BASICS The text in the dialog box clearly explains what prevents the requested action from being executed An immediate error is NOT logged to the Current Error Log or the Previous Error Log The status bar of the PumpWorks main window reads No Errors and the motion status display does not show an error status for that pump cylinder 9 2 2 Logged Errors A logged error is entered into the Current Error Log and Previous Error Log but no dialog box appears on the window The status bar of the Pump Works main window displays Error Present or Check Error Log Most logged error messages are very easy to understand and the user is able to correct the problem quickly An example of a logged error is Error Over Pressure on Cylinder 1A This means that the safety pressure in pump cylinder 1A set by the user was exceeded by the pump cylinder and caused a digital overpressure error This error would cause an operating pump to stop While most logged error conditions are self explanatory some are explained in additional detail b
