EC-TYPE EXAMINATION CERTIFICATE VTT 04 ATEX 031X

Description of Equipment

The liquid level switch type SET-1000 or SET-2000 is an associated apparatus and |
supplies one (SET-1000) or two (SET-2000) intrinsically safe level probes. The
material of the enclosure is polycarbonate.

The liquid level switch type SET-1000 or SET-2000 shall be installed outside the
explosive area.

Electrical data

Supply voltage according to the type plate: 230 Vac or 110 V ac, 50/60 Hz, Um =
253 V or 11-17 V de, Um = 23 V. The ac version liquid level switch is equipped
with a 125 mA supply fuse and the dc version is equipped with a 315 mA supply
fuse. There are one (SET-1000) or two (set-2000) potentially free relay contact
outputs (250 V, 5 A, 100 VA).

The maximum values of the intrinsically safe output values are:

 

Uo lo Po
14,7V 55 mA 297 mW

 

 

Maximus external capacitance and inductance values are:

 

 

 

 

 

 

 

 

Gas group Co Lo Lo/Ro

TA 3,84 LF 30 mH 466 pH/Q

 

The output supply is of trapezoidal characteristic according to prEN50039 (2001)
with parameters Ug = 21,95 V or R = 404 Q and maximum combined external
capacitance and inductance values are:
