The following options can be selected for the configuration of pin 11 (with a 3465 Detector TCC):
P11(OVLD) = 1 Overload output active for cell 1 only
P11(OVLD) = 2 Overload output active for cell 2 only
P11(OVLD) = 3 Overload output active for cell 3 only
P11(OVLD) = Overload output inactive
P11(OVLD) = All* Overload output active for all cells present
*When this option is selected, the overload output will be active for all cells present in the 3465
Detector. If the cell current of any cell goes out of range, the overload input pin 11 becomes
active.
11.3.5 Cell on Cell off
The 3465 Detector has three TTL inputs to switch on cells (pins 12-14) and three inputs to switch
off cells (pins 15-17). This input command can be used, for example, to switch on and stabilize
the flow cell early in the morning by means of a timer. Two of the inputs are configurable (pin 12
and pin 15; cell on and off, respectively) in the IO menu (see the previous chapter about overload
output). The configuration settings of these inputs are: 1, 2, 3, 4, 5,’ ‘, and all. If all is selected, all
cells present in the 3465 Detector are switched on or off when the corresponding input is
triggered.
11.3.6 Autozero
The 3465 Detector has three TTL inputs (pins 18 - 20) available to autozero cell current.
Triggering these inputs enables external activation of the autozero command. This function is
active only when the "I-cell" is displayed. One autozero input (pin 18) is configurable in the IO
menu (see the previous chapter about overload output). The configuration settings of this input
are 1, 2, 3, 4, 5, ' ', and all. If "all" is selected, the cell current of all cells present in the 3465
Detector are zeroed when the input is triggered.
11.3.7 3465 Start
The 3465 Detector has four TTL inputs (pins 21 – 24) available to start data acquisition and/or
start a scan. One start input (pin 21) is configurable in the IO menu and can be used, for
example, to start the data acquisition for all cells synchronously using only one trigger input when
All
is selected.

The manufacturer accepts no liability for damage, direct or indirect, caused by connecting
this instrument to devices that do not meet the relevant safety standards.
