3.8.2. Switches S201, S202, and S801
Switches S201 (A53) and S202 (A54) are used to select a current (0-20 mA) or a voltage (-10 to
10 V) configuration for 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 drawing
Diagram showing all electrical terminals
in section
Electrical Installation.
Default setting:
S201 (A53) = OFF (voltage input)
S202 (A54) = OFF (voltage input)
S801 (Bus termination) = OFF
When changing the function of S201, S202 or S801, be careful not to force the switch
over. Removing the LCP fixture (cradle) when operating the switches is recommen-
ded. The switches must not be operated while the adjustable frequency drive is
powered.
