This section applies only to units shipping without MicroTech
controllers but need eld controls installed.
I/O Terminals

Voltage and Current Selection for
Analog Inputs
Switch S1 selects voltage (0 [2]…10 V / -10…10 V) or current
(0 [4]…20 mA / -20…20 mA) as the signal types for analog
inputs AI1 and AI2. The factory settings are unipolar voltage
for AI1 (0[2]…10V) and unipolar current for AI2 (0[4]…20mA),
which correspond to the default usage in the application
macros. The switch is located to the left of I/O terminal 9,
Figure 4.
