5.2.14 Switches S201, S202, and S801
Switches S201 (A53) and S202 (A54) are used to select a
current (0–20 mA) or a voltage (0–10 V) configuration of
the analog input terminals 53 and 54 respectively.
Switch S801 (BUS TER.) can be used to enable termination
on the RS-485 port (terminals 68 and 69).
See
Figure 5.25
Default setting:
S201 (A53) = OFF (voltage input)
S202 (A54) = OFF (voltage input)
S801 (Bus termination) = OFF
NOTE!
It is recommended to only change switch position at
power off.
