3 Prepare the e2695 Separations Module for Operation
102 July 29, 2013, 715003794 Rev. B
• Choose Ignore if the Stop Flow I/O terminals of the separations
module are not used.
• Choose High if the output connection from the external autosampler
to the Stop Flow I/O terminals of the Separations Module changes to
a high (more positive) TTL-level.
• Choose Low if the output connection from the external autosampler
to the Stop Flow I/O terminals of the separations module changes to
a low (more negative) TTL-level.
5. Set the Hold 1 field to the appropriate condition (High or Low), and then
press Enter.
• Choose High if the output connection from the external autosampler
to the Hold 1 Inject terminals of the separations module changes to
a high (more positive) TTL-level to initiate a chromatographic run
(and prevent an injection by the separations module).
• Choose Low if the output connection from the external autosampler
to the Hold 1 Inject terminals of the separations module changes to
a low (more negative) TTL-level to initiate a chromatographic run
(and prevent an injection by the separations module).
Requirement: If you are configuring the separations module with a
Waters 2700 Sample Manager, select Low.
6. Set the Logic field to Or, and then press Enter.
7. Set the Hold 2 field to Ignore, and then press Enter.
8. Press the OK screen key to save your selections.
Controlled via RS-232 (ASCII) or (binary) mode
In these remote control modes, a non-Waters data system (a mass
spectrometry system, for example) controls the separations module using
RS-232 ASCII or binary communications. The separations module disconnects
from the Ethernet or IEEE-488 interface bus when either of these modes is
selected. The separations module can control other non-IEEE devices in the
HPLC system using the I/O connections on the rear panel. See “I/O signal
connections” on page 71 for information on I/O connections.
