¾ Since the signal outputs cannot be activated simultaneously owing to the limited number of ter-
minals available, one of the aforementioned options must be selected. Field bus devices
(Profibus PA) are not outfitted with an analog or impulse output.
¾ A maximum of 8 signal output terminals is available (in addition to the terminal for the control unit
and Profibus PA).
¾ “Increased safety” type of protection signal outputs are to be connected only to "Extra low volt-
age" degree of protection circuits with safe electrical isolation in accordance with DIN VDE 0100
part 410.
¾ Under no circumstances are “Increased safety” signal outputs to be combined with “In-
trinsic safety” signal outputs .
¾ If interface output RS 485 (under development and not currently available), which is only avail-
able in an “Increased safety” model, is selected, all signal outputs must also have this type of pro-
tection.
¾ If “Control input” or “RS 485 interface” are selected, current output 2 is not supplied.
¾ If the sensor and transmitter are interconnected using a cable, the following cable is to be used:
SLI2Y (SP) CY 5 x 2 x 0.5 mm (for explosion-proof applications, grey for non-explosion
proof applications).
