Connections
It is possible to use control inputs and setpoint outputs if you add an optional digital I/O board (3 inputs and 3
outputs) to the instrument. The electrical connection of the inputs and outputs should be made as shown in Fig.
9.1.

9.2.2. Setup
[1--] Configuration Block
In this block the parameters are located which are being used to set up the digital inputs and outputs.
[13-] Digital Inputs / Outputs
FT-11(D) has optionally 3 digital inputs and 3 digital outputs.
[130 X] Outputs
The outputs operate with respect to the displayed weight value. In the 3
rd
selection the Output 3 operates
as Error and Alarm output.
0 = Disabled (factory default)
1 = (Output1 = Sp1), (Output2 = Sp2), (Output3 = Sp3)
2 = (Output1 = Sp1), (Output2 = Sp2), (Output3 = Stable)
3 = (Output1 = Sp1), (Output2 = Sp2), (Output3 = Error and Alarm)
[131 X] Input 1
0 = Disabled (factory default)
1 = Zero
2 = Tare
3 = Clear
4 = Print
5 = Key lock
Warning:
This input will be used as tilt switch input for tilting applications (parameter [207] 0)
