1 Overview
The Magnetic Field XL Generator is part of a complete HIT-NOT Proximity Detection system
from Frederick Energy Products which provides audible and visual warnings to both individuals
and to vehicle operators to alert them that the individual has entered too close to an operating
piece of equipment and is in a dangerous situation. The Magnetic Field XL Generator attaches
directly to a vehicle or piece of machinery. The HIT-NOT® Proximity system includes an optional
add-on module, which is not standard on the basic system.
1.1 Theory of Operation
The functions of the Magnetic Field XL Generator are:
 To generate a 73 kHz field around a vehicle or piece of machinery to act as a protection
zone for collision avoidance and for proximity detection for the protection of
individuals.
 To receive a 916.48 MHz RF signal from a Personal Alarm Device (PAD).
 An add-on for a Collision Avoidance Module (CAM) between vehicles.
The Magnetic Field XL Generator has an internal 73 kHz generator and a wire wrapped ferrite
radiator that creates a field to serve as a cautionary zone around the vehicle or machine. When
a Personal Alarm Device (PAD) is in close proximity of the Magnetic Field XL Generator, the PAD
will detect the 73 kHz magnetic field from the generator and analyze its field strength. If the
73kHz field strength received by the PAD is above a certain threshold, indicating the distance
between the Magnetic Field XL Generator and the PAD is close enough to signify a Warning or
Danger condition, then it will reply to the Magnetic Field XL Generator with an 916.48 MHz
transmission. The Magnetic Field XL Generator has its 916.48 MHz receiver on when it is
transmitting the 73 kHz field and is “listening” to receive any 916.48 MHz transmissions from an
individual equipped with a PAD to indicate the individual is too close to the vehicle and
warrants a warning or danger condition. If the Magnetic Field XL Generator receives indication
that a Warning or Danger condition exists, it will turn on the appropriate LED indicator and
connected Warning Module (sounder for the Magnetic Field Generator).
1.2 Operating Frequency
The Magnetic Field XL Generator will transmit on a frequency of 73 kHz and receive on a
frequency of 916.48 MHz.
1.3 Label Information
The Magnetic Field XL Generator label is located on the side of the housing. Information
includes the Serial Number, Model Number, Power In, FCC/IC Identification, “PWM” adjustment
location, and References to this manual.
