BWI creates
a higher standard in overspeed detection
for elevators, emergency escape hoists,
downhill conveyors and cranes. Introducing
the Eagle®
Overspeed Monitor - A highly
accurate, fail-safe electronic speed switch
featuring state of the art circuitry design.
FACTORY
PROGRAMMED
No field
calibration required. Each unit is factory
programmed to the customer's specific trip
point.
TRUE
TRIP POINT TEST
The two-position
test switch precisely simulates a true overspeed
or fault condition without operator adjustment
or recalibration.
Placing the
test switch in the overspeed position internally
increases the sensor input signal to the
preset trip point and causes the control
relay to de-energize.
Placing the
switch in the fault position internally
shorts the sensor input signal, which simulates
a loss of sensor signal, also causing the
control relay to de-energize.
RELAY
OPERATION
The relay
energizes when AC power is applied. If an
overspeed or sensor fault condition is detected,
the relay de-energizes.
ORDERING
INFORMATION
Specify RPM
trip point desired. Example: Model 22-4100-327
will trip at 327 RPM
