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 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 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 use force
for the switch over. It is recommended
to remove the LCP fixture (cradle) when operating
the switches. The switches must not be operated
with power on the frequency converter.
