- Alu-housing
- IP65
Features
The SWE electronic speed monitor is used for underspeed monitoring, slip monitoring and standstill monitoring, especially in harsh “on-site operation”. The opto-electronic pulse transducer, the speed evaluation relay and the power supply unit are combined into a single unit in the compact device. This compact design eliminates the need for connecting cables between the encoder and evaluation relay, which are prone to interference in conventional electronic speed monitoring systems. This ensures interference-free signal transmission even over extremely long distances. Only the supply voltage and the cables for the potential-free relay contact output are connected to the SWE. The Kiepe electronic speed monitor type SWE conforms to the Low Voltage Directive 2014/35/EU and EMC Directive 2014/30/ EU.
Note The SWE may only be used in control circuits.

The device has a separate connection chamber in which the connection terminals, the potentiometers for setting the switching points and the start-up delay as well as the LED for the operating display are located. The time for the start up delay can be set from 0.5 to 15 seconds. If the drive speed exceeds the pre-set operating speed, the relay is energized and the LED is lit. If the drive speed falls below the pre-set operating speed, the relay drops. The LED is extinguished.

The SWE electronic speed monitors are supplied ready for operation. Speed monitoring devices type SWE are attached to the substructure of the monitored machine using 4 M6 screws each. This is done using flange (F1, F2) or fixing foot F4. The connection to the rotating shaft is made using couplings (K1, K7). When the speed is taken directly from the belt, the SWE is attached to the belt drive B. The belt drive is pressed against the cleaned side of the belt using a hinge pedestal GB. The electrical connection is made when the device is open via the cable gland included in the scope of delivery directly to the accessible connection terminals.
Note When using the belt drive B, make sure that the belt load cannot damage the SWE. With direct connection using fasteners, care must be taken to ensure that the SWE can resonate with the rotating part of the machine. (See mounting drawing)
