4.6 Triggering of functions
4.6.1 keys
The two 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.)
FILL

sor module to next
position ("STEP"
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 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
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 key (see section 4.4.2).
