4.3.2.2 DIP switches (S1, S2)
The analogue inputs in the device are suitable for
current and voltage setpoints. For correct
processing of current setpoints (0-20 mA /
4-20 mA ) the relevant DIP switch ( S1 – bit 2 or 3)
must be set to current signals (" ON ").
DIP switch ( S1 – bit 1) sets the terminating
resistance of the system bus.
The system settings can be made via DIP switch
( S2 ). Settings made at DIP switch (S2) have
priority over the parameters P509, P514 and
P515.
As delivered, all DIP switches are in the "0" ("OFF") position.
