Article number: 9336

OBJECTIVE or GOAL

Install an external valve using the RS232 port of Column Manager CM-A or CM-30S.

Minimum requirement: Control released with the June 2011 Driver Pack for ACQUITY Systems

  • CM-A supports control for up to three external valves  

ENVIRONMENT

  • H-Class Column Manager - Active
  • UPC2 30 cm Single Zone Column Manager

 

  • Optional External Valves (RS232 Controlled):

  • 417000138 - VALVE, SELECTOR, 2 POSITION, 10 PORT, TI
  • 417000139 - VALVE, SELECTOR, 6 POS. 7 PORT PEEK
  • 417000150 - VALVE, SELECTOR, 10-POS, SS, RS232

 

PROCEDURE

Required Parts:

  • 441000459 - 3-gang, RS-232 serial-adaptor cable
  • 700010277 - Adapter, Fem-to-Fem, Serial Cable Coupler
    • The "serial cable coupler"  may be required to connect the 3-gang, RS-232 serial-adaptor cable to the CSV cable

 

To connect an external valve to the CM-30S:

  1. Depending on whether you are using one external valve or two or more valves, set the valve addresses as follows:
  2. Ensure that the external valve address is 0.
    • Use a #0 flat-blade screwdriver to turn the screw on the back panel of the valve, setting the address to 0.
    • If you are using more than one external valve, set the address of the second valve to 1 and that of a third valve to 2.
      • Requirement: The turnscrew on the back of the external valve must align precisely with the address number. Otherwise, the external valve cannot operate.

  1. Connect the standard end of the 3-gang, RS-232 serial-adaptor cable labeled “RS-232 B” to the COM B RS-232 port on the back of the Column Manager.

  1. Connect the external valve’s serial cable to a female-to-female serial cable coupler adapter.

  1. Connect the coupler adapter to the connector labeled “1” on the 3-gang RS-232 serial-adaptor cable.
    • If you are connecting more than one external valve:
      1. Connect the second external valve’s serial-adaptor cable to a female-to-female serial cable coupler adapter.
      2. Connect the coupler adapter to the connector labeled “2” on the 3-gang, external valve’s serial adapter cable.
      3. Connect a third external valve’s serial-adaptor cable to a female-to-female serial cable coupler adapter.
      4. Connect the coupler adapter to the connector labeled “3” on the 3-gang, external valve’s serial adapter cable.
  2. Connect the external valve’s power cord to a suitable wall outlet.

  3. Press the “Local-Remote” button to select “Remote”.

ADDITIONAL INFORMATION

Note: External valve control by RS232 is not supported with the original ACQUITY UPLC Column Manager.
