1 Overview
The Magnetic Field 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 action needs to be taken to avoid a collision with the equipment. The
Magnetic Field Generator (MFG) attaches directly to a vehicle or piece of machinery. The HIT-
NOT® Proximity system can include an optional, add-on Collision Avoidance Module (CAM),
which is not standard on the basic system.
1.1 Theory of Operation
Operations for both the standard generator (model DDAC-PDS) and a generator with optional,
add-on Collision Avoidance Module (model DDAC-PDS-C) are described
1.1.1 Operations Common to Standard Generators and Generators with CAMs
The functions of the Standard Magnetic Field Generator and Generator with CAM 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) or from a
Generator equipped with CAM.
The Magnetic Field 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 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 Generator and the PAD is close enough to signify a Warning or
Danger condition, then it will reply to the Magnetic Field Generator with an 916.48 MHz
transmission. The Magnetic Field 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 (or from another MFG with CAM) to indicate the individual (or
vehicle) is too close to the vehicle and warrants a warning or danger condition. If the Magnetic
Field Generator receives indication that a Warning or Danger condition exists, it will turn on the
appropriate indicator in a connected Warning Module (WM) or Proximity Telemetric Module
(PTM) that provide alerts to the machine operator via LED and audible alarm.
There also is an optional auxiliary warning module (WM-LO) that will connect to the MFG and
indicate visual LED warning when alert conditions exist. This is a redundant indicator for
