Safety Interlocks; Radio Frequency Radiation; Ultraviolet Radiation - PerkinElmer AVIO 500 Customer Hardware And Service Manual

Safety Interlocks

The instrument has safety interlocks to protect the operator from radio frequency
(RF) radiation and ultraviolet radiation, and to prevent access to high voltage areas.
Do not attempt to defeat the safety interlocks. This would place the
!
operator's safety at risk.
Warning
Avertissement:
Ne pas tenter de contourner les verrous de sécurité. Cela placerait la
sécurité de l'opérateur à risque.
The following interlocks must be satisfied in order to ignite the plasma. If any of
these interlocks is interrupted while the plasma is on, the plasma will automatically
be shut down.
• The front door on the torch compartment must be closed before the plasma can
ignite.
• Argon pressures for the torch must be correct.
• Emergency Off Switch must be released.
• Cooling water must be flowing to the oscillator.
• Quick change torch must be installed.
• The shear gas must be flowing.

Radio Frequency Radiation

The instrument generates high levels of Radio Frequency (RF) energy, which is
potentially hazardous if allowed to escape. The instrument is designed to contain
the RF energy within the shielded enclosures of the sample compartment and the
RF power supply. Safety interlocks prevent you from operating the system without
all covers, doors, and shields in place.

Ultraviolet Radiation

The plasma generates high intensity ultraviolet radiation. A safety interlock is used
to automatically shut off the plasma if the torch compartment door is opened or the
