4.6 Triggering of functions
4.6.1 <FILL> keys
The two <FILL> keys at the 733 IC Separation Center each have the
following function, which depends on the instrument version:
733.0010 (1 valve) 733.0X20 (2 valves) 733.0X30 (valve+ suppr.)

function)
If the injection valve is in the
"FILL" position, the green LED in
the key lights up. In this position
the injection valve is connected
as shown in the diagram oppo-
site:
The sample loop is filled by
siphoning in the sample so-
lution using the syringe.
The eluent flows directly to
the separating column.
The "FILL" function can be triggered at any time with the <FILL> key
also in the edit mode or when a program is running. If this is not re-
quired, the key can be locked. For this, the parameter ">CONFIG/733 IC
Sep.Cent./control" must be set to "732 only" under the <CONFIG>
key (see section 4.4.2). Switching of the injection valve is then possible
only using the 732 IC Detector via a programmed "FILL" command or
with ">CONFIG/733 IC Sep.Cent./trigger = fill".
With the 733.0030 IC Separation Center, switching of the suppressor
module to the next position can be triggered automatically by the
switching of injection valve A to the "FILL" position. For this, the pa-
rameter ">CONFIG/733/suppressor/auto step" must be set to "fill"
under the <CONFIG> key (see section 4.4.2).
