operator convenience and is normally located at a different location on the machine (e.g. at a
point that is visible to the operator when the machine is traveling in reverse).
1.1.2 Operations Unique to Generators with CAMs
The functions unique to the Generators with CAM are: (Note: these are in addition to those
described in Section 1.1.1)
To transmit a 916.48 MHz signal from the CAM to a Magnetic Field Generator in
another vehicle.
The Magnetic Field Generator with CAM performs the functions for pedestrians wearing PADs
as described in Section 1.1.1. The CAM also detects magnetic fields from other vehicles with
MFGs to provide warning against collision between the two vehicles.
When Vehicle 1 is in close proximity of Vehicle 2, the CAM (Vehicle 1) will detect the 73 kHz
magnetic field from the generator (Vehicle 2) and analyze its field strength. If the 73 kHz field
strength received by the CAM (Vehicle 1) is above a certain threshold, indicating the distance
between Vehicle 2 and Vehicle 1 is close enough to signify a Warning condition, the CAM will
reply to the Magnetic Field Generator in Vehicle 2 with a 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 a Personal Alarm Device
(PAD) or generator equipped with a CAM to indicate the individual or vehicle is too close 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 LED indicator on the
Warning Module or Proximity Telemetric Module (PTM). Warning Module simply alerts and the
PTM alerts and also records the events.
1.2 Operating Frequency
The Magnetic Field Generator will transmit on a frequency of 73 kHz and receive on a frequency
of 916.48 MHz. The CAM will transmit on a frequency of 916.48 MHz and receive magnetic fields on a
frequency of 73 KHz. The CAM is programmed not to recognize the 73 KHz form its own Generator.
1.3 Label Information
Magnetic Field Generators have two labels. One label, located on the top housing side opposite
the mounting arm, provides general information. The second label, located on the rear face,
provides serial number.
