Preface | Argus Radar Operator Manual
High voltage
Radar equipment includes high voltage that can cause injury or loss of life. Danger exists only
when the units are opened and exposing internal circuits, as when servicing the equipment.
The ARGUS Radar has been carefully designed to protect personnel from possible injury from
high voltages.
Nevertheless, it is recommended that the Main Power Line shall always be OFF, as an added
protection when inspecting or servicing the equipment.
Although every effort has been made to eliminate danger to personnel, no responsibility is
accepted for any injury or loss of life suffered in connection with this equipment.
Safety switch
The Radar Unit is provided with a safety switch, which disables the antenna rotation during
maintenance and avoids high voltage damage. Always turn the safety switch off, whenever
the procedure advises to do so (for instance, before performing any maintenance or installa-
tion procedure). Ignoring safety switch operation may produce hazard of electrocution as well
as other severe injures.
Safety precautions
Purpose
The described safety precautions are applicable to the ARGUS Radar System. Depending
upon the material to be highlighted, the following notes are used in this manual.
¼
Note: An essential operating or maintenance procedure, condition or statement which must
be highlighted.
Whenever a precaution, relating specifically to a part of this manual is needed, the informa-
tion is given in the relevant part of the manual. Warnings and Cautions precede applicable
text.
Safety operations
Main power line is always present on terminal board and fuses. During normal operation
(front cover closed), the unit can quickly be disconnected from the main power line, setting
the relevant circuit breaker, located on the electric switchboard, to OFF.
Safety summary
The following are general safety precautions not related to any specific procedure and
therefore do not appear elsewhere in this manual. These are recommended precautions that
personnel must understand and apply during most phases of operation and maintenance.
KEEP AWAY FROM LIVE CIRCUIT
Operating personnel must at all times observe all safety regulations.
Do not replace components or make adjustments inside the unit with the high voltage sup-
ply turned ON. Under certain conditions, dangerous potentials may exist when the power
breaker is in OFF position, also due to charges retained by capacitors. To avoid casualties,
always remove power and discharge a circuit to ground before touching it.
DO NOT SERVICE OR ADJUST ALONE
Under no circumstances should any person initiate servicing or adjusting the unit without the
presence of someone capable of helping.
RESUSCITATION
Personnel working with or near high voltage should be familiar with modern methods of
resuscitation. Such information may be obtained from the Bureau of Medicine and Surgery.
