Interface
The units must be parameterized before they can be controlled. Parameterization is
done in a menu (see 'Parameterization').
The interface has the following formats, depending on the unit version:
S102-xx/xx/0x-00x/0B-S0:
RS485 and RS232
S102-xx/xx/0x-00x/0B-T0:
TTY 20mA and RS232
Select in menu item 1 between the formats which are available in the unit.
In interface format RS485, you can select several settings in the menu item 1.
'Project planning information' describes which setting has to be selected.
Units with a character height of 25 mm and TTY interface supply terminal P with an
auxiliary voltage galvanically isolated from the power supply, for an active connection
of the current loop (24 V ± 20%, max. 50 mA, reference potential = COM).
