General:
The electronic rotational speed monitor SWE-compact comprises
constructively the opto-electronic pulse transducer, the speed
analysing relay and the power supply in one unit. By this compact
form of construction, the connecting wires between the pulse
transducer and the analysing relay which are susceptible to
interferences considering the usual electronic speed monitoring
systems, are eliminated. Only the supply voltage as well as the
cables for the voltage-free output relay contacts need to be
connected to the SWE-compact.
Electronic rotational monitoring of underspeed, control of slip,
stand-still monitoring.
Installation and Operation:
The unit has a separate chamber containing the connection
terminals, the knob of the setpoint potentiometer, the LED as well
as the knob of the start-up delay potentiometer.
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.
An opto-coupler can be provided instead of the output relais.
The SWE-compact has the same fixing dimensions as the approved
devices type SWS, DKS and EOGS. All the couplings and accessoires
of the devices can be used. For conveyors, speed
monitoring can be effected directly from the conveyor by means
of the SWE-compact with coupled conveyor monitor stand and
belt drive „B“.
Decisive features of the SWE-compact are:
Entirely free of maintenance, interference proof transmission of
signals even over extremely long distances, simple and costsaving
setting up, monitoring of lowest rotating speeds
(stand-still monitoring) and, above all, its compact construction
especially planned for the operation under very rough service
conditions.
