How to connect an external Solvent Select Valve/s (SSV) to a Solvent Manager or Column Manager - WKB27360

ENVIRONMENT

• ACQUITY UPLC Binary Solvent Manager (BSM)
• ACQUITY UPLC I-Class
• ACQUITY UPLC H-Class
• ACQUITY UPLC Premier
• ACQUITY UPLC Column Manager
• Empower 3

ANSWER

Event 4 is always on (or closed) for all external valve positions. Hard wire the valve connection that should be connected to event 4 directly to ground. This will mimic the event being on all the time, which is required for all valve positions.

ADDITIONAL INFORMATION

• SSV Event Switch Connections on an I-Class BSM. Note that the rear connection ports may differ between different solvent manager variants.
  • SSV on an I-Class system
  • SSV on an ACQ Premier system

• The Solvent Selection Valve may also be installed on the Sample Manager.

Solvent Selection Valve Installation Instructions
The

• The Solvent Selection Valve may also be controlled by the column manager (CM-A).
• The Solvent Selection Valve must be configured in the method. See the table below for configuration schemes.

• Two (2) 6/7 port valves can be configured to the BSM and the CM-A controlled via Empower. BSM programmed through the switches and the other with RS232 communcation. 
• Alternately: Two (2) 6/7 port valves can be configured to the CM-A controlled via Empower. Use two RS-232 valves: 417000139 - VALVE, SELECTOR, 6 POS. 7 PORT PEEK  and 441000459-441000459 - 3-gang, RS-232 serial-adaptor cable. This method is more user friendly without the use of the on/off switches and the use of RS232 communication. 
• See WKB9338 and WKB9336 for more information on this setup.
