Flush factor: 10
•
TTL homing delay: 90 sec
The TTL homing delay specifies the time delay before homing (raising)
the needle after delivery. For information about the flush factor, see
Section 3.5.2 .
If the Dionex AS-DV has been connected to Chromeleon, the delivery
speed, flush factor, and TTL homing delay last entered are used.
To change one of the options, you can connect the Dionex AS-DV to
Chromeleon, change the option’s value, and then disconnect the Dionex
AS-DV from Chromeleon.
C.1.3 TTL Input Control Modes
To accommodate different controlling devices, the Dionex AS-DV TTL
input responds to four types of signals. The default control mode, normal
edge, is compatible with the output signals provided by Dionex products.
If the device connected to the Dionex AS-DV does not send a normal
edge signal, select the appropriate control mode. Refer to the
documentation provided with the controlling device and the information
below to determine the correct mode.
•
Normal Edge : In normal edge
operation, the negative (falling)
edge of a signal turns on the
action.
The function of the positive
(rising) edge depends on the action: For on/off, or other actions that
have two options, the rising edge turns off the action. However, for
functions with only one option, the rising edge has no effect.
•
Inverted Edge : The inverted
edge mode works identically to
the normal edge mode except
that the positive and negative
edges are reversed in function.
