The arm has been blocked and or cannot function properly.
Remove the obstruction and press Resume analysis (key 1) to
continue the sequence from the point it stopped.
If a Sample Changer is in use, specify if the grounding of the
measuring cell takes place using an external connection to the
sample changer. This is the case when a solution is grounded using a
metal shield or via a conductivity cell connected to a conductivity
meter.
Refer to "Working mode", page
Sample changer error: The SAC option addressed is missing and not
installed on the sample changer.
Examples:
• Dynamic rinses are programmed in the sequence and no dynamic
rinse module is installed and the sample changer.
Review the Setup > Configuration parameters and/or install
missing pump (in particular, check the electrical connection
between the pump and the sample changer).
• A reagent addition is programmed in the sample preparation and
no peristaltic pump is installed on the sample changer.
Review the Edit sequence parameters, parameter Sample prepara-
tion no. and/or install missing peristaltic pump (in particular, check
the electrical connection between the pump and the sample
changer).
For TitraMaster 85 users only, check and, if necessary, edit the
sample preparation routine.

Either the data transmission between sample changer and the
workstation cannot be performed properly, in which case you should
check the cable connections, or the measurement stopped due to a
movement error.
End the sequence by pressing key Stop on the sample changer
keypad or key Stop of the workstation, and check that nothing is
obstructing sample changer movements.
