Auxiliary input The auxiliary input socket can be connected to an external device unit
used to send an analysis start command to the Titration Manager. The
analysis is a sequence of methods with manual change of the titration
beakers (Working mode = Sequence,
see "Working mode", page
226 ).
The external device unit is to be connected to the red and black IN
banana sockets of the Titration Manager. The red banana socket
receives the TTL 0 ± 5 V auxiliary signal and the black banana socket
is connected to the instrument electrical zero.
Proceed as follows to trigger a sequence of methods by an auxiliary
signal input:
• In the Configuration menu, select
Controlled by TTL IN = Yes.
• Connect the auxiliary control unit to red and black IN banana
sockets of the Titration Manager.
• Run the sequence. The Titration Manager displays a waiting for
auxiliary signal message. The sequence is started as soon as the
auxiliary signal is received.
