The integrated safety systems must be checked at regular
intervals (d= daily, w = weekly, m = monthly, ½ y = half-yearly,
y = yearly).
The test methods that are to be applied are:
V = visual inspection, F = function test, M = measurement.
The operator must implement the following in the overall
plant:
Mains Isolator (Main Switch)
The high voltage power supply is
connected to the main power supply
system. The electron beam evaporator
is connected to and disconnected from
the power supply with the main switch
for this power supply system.
When the main switch is switched off for cleaning, maintenance
and repair work, it must be locked with a padlock to prevent
unauthorised switching on.
Emergency Stop System
The high voltage power supply has to
be integrated in a master emergency
stop system that immediately puts the
high voltage power supply into a safe
operating state when actuated.
