Overspeed/Underspeed Monitor KF**-DWB-(Ex)1.D Overview Typical applications for the Overspeed/Underspeed Monitors KF**-DWB-(Ex)1.D of the K-System (abbreviated DWB) are limit-value monitoring during flow and rotational-speed measurements (Max alarm and Min alarm). The Overspeed/Underspeed Monitors are parameterized using an integrated control panel. More information (for example, certificates and data sheets for the DWB and the operating manual for the K-System) can be found on our webpage www.pepperl-fuchs.com (enter *DWB* in the product... -
Page 7: Inputs And Outputs
Overspeed/Underspeed Monitor KF**-DWB-(Ex)1.D Overview Inputs and outputs Field device input A K-System DWB from Pepperl+Fuchs has • an input for connecting a field device. − With KF**-DWB-Ex1.D, this input is intrinsically safe (blue terminal block). You may connect either a NAMUR sensor or a mechanical contact. -
Page 8: Safety Notes
If faults cannot be eliminated, the devices must be taken out of operation and protected from being placed in service again inadvertently. Devices must only be repaired directly by the manufacturer Pepperl+Fuchs. Tampering with or making changes to the devices is dangerous and therefore not permitted. They render the warranty void. -
Page 9: Explosion Protection
IP20 and must therefore be protected from undesirable ambient conditions (water, small foreign objects). Attention The devices of the K-system from Pepperl+Fuchs and thus also the Overspeed/Underspeed Monitor KF**-DWB-(Ex)1.D can be mounted on a 35 mm standard rail corresponding to DIN EN 60175. The devices must be snapped onto the rail vertically, and never slanted or tipped to the side. -
