  • Page 3: Introduction

    Introduction MX Series II Modules are self-contained automated valves available in a variety of flowpaths for use in many applications. For multiple valve applications, the MX II’s unique “Snap n’ Stack” system allows Modules to be stacked on top of each other or connected side to side to conserve bench space and reduce tubing connection volumes.

  • Page 17 2. Using the Timed Events Table (This mode of control should not be used when the MX Series II module is being controlled by another instrument. In that case use the timed events table from the controlling instrument.) a) Click on the Timed Events Tab. b) If you wish to set the starting position of the valve enter 0 (zero) in the first time field.
  • Page 18 c) Continue inputting the times (in seconds) when you wish the valve to change positions and the position it should move to on the adjacent line until you have completed your program. (You may use up to 20 timed events. Times may be entered to the tenths of a second.) d) When you are ready to begin your program click run.
  • Page 19 f) Please note that the events must be listed in chronological order or an error will occur and the program will terminate at the point of the error. g) If an invalid position is requested this will also result in an error which will stop the program at that point.
