LIFT
Positioning the lift
•
Raises or lowers the lift to a
predefined position. These posi-
tions (work position, rinse position,
shift position, special position) can
be defined in the Configuration
menu as rack-specific.
•
An absolute lift position in mm can
also be given.
Numerical entry ('9')
or
Positioning the lift
•
The lift can be run to the predefined
positions (work position, rinse
position, shift position, special
position) in a sequence.
•
An absolute lift position in mm can
also be given.
PUMP
4
Control pump
•
The
switch the peristaltic pump of the
766 IC Sample Processor on or off.
•
The state of the pump is shown in
the second display line in the nor-
mal state.
'PUMP+'
means
"switched on",
'PUMP–'
means
"switched off").
Numerical entry ('4')
or
Control pump
•
The pump can be specifically
switched on and off in a sequence
or set to operate for a fixed amount
of time (in seconds).
1
SCAN
Display input signals
•
Display of the incoming signal or
data on the remote or RS interface.
This function serves to control the
data communication or states of
connected instruments.
•
The first parameter represents the
interface selection. The signals for
data being received at that moment
are displayed as the second pa-
rameter.
•
If the parallel remote interface (
Rm
)
is selected, the signal states of the
incoming remote lines are dis-
played in binary form (
1
= line
active,
0
= line inactive). Details
see section 5.1.
•
If the serial RS232 interface (
RS
) is
selected, the character string being
received is displayed line by line
(14 characters). Details see section
5.2.
Numerical entry ('1')
or
Scan input signals
•
In a sequence the SCAN command
causes method processing to stop
until the predefined bit pattern (with
the remote interface) or the given
character string (with the RS232
interface) is received.
•
Predefined bit patterns are
available for the remote interface
and can be selected via simple
short-names (e.g.
'Ready 1'
or
'End 2'
).
•
Character strings consisting of 14
ASCII characters may be defined
with the RS232 interface.
