Teach-in via multifunctional input
7.4.1
Setting pin 2 output (UC40-xxxxxH only)
Overview
The UC40-xxxxxH product type has a second output. For this output, it is possible to
choose between automatic current or voltage output and fixed current, voltage or digital
output. The desired output must be selected before the teach-in process.
With automatic selection of current or voltage output (factory setting), the device
checks the load at the analog output. Depending on the load, the device automatically
selects current or voltage output.
Approach
1.
Switch off the supply voltage.
2.
Ensure that connected hardware is not damaged by the 24 V output voltage.
3.
Apply
M
at MF.
4.
Switch on the supply voltage.
