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
Note
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 keypad fixture (cradle) when operating the switches. The switches must not be operated with power on the
