CAUTION
►
Risk of injury from contact with cold surfaces!
►
When using very cold coolants, surfaces such as those on the emis-
sion condenser can become dangerously low.
►
The operator must ensure safe operation and take measures to protect
the user if necessary (see sections 2.3 Protective measures and 6.3.1
Access control).
2.5.4
Vacuum controller
– system functions
The following settings for the "control systems" must be assessed separately for particular
vacuum applications (see section
.
"Allow ventilation"
When this function is activated, the application can be manually (see section
display) or automatically ventilated via the pressure control.
Through activation of the function, media, which may be harmful, can escape from the
application and enter into the environment.
ATTENTION
►
If the function is activated, there is a possibility that the ambient air will
enter into the applications.
This can result in uncontrolled reactions in the application.
►
Note that an inert gas may need to be connected to the ventilation
valve (see sections 3.4 Application connections and 4.3.2 Back of the
device).
"Auto Start"
If the "Auto Start" function is activated, the device starts automatically after
a power failure or after the power switch was pressed. This can cause undesired after-
effects in your application.
An automatic start only occurs if an operating mode was started previously.
Make sure that critical applications are not unsupervised!
WARNING
►
Activating the "Auto start" parameter in the system setting can result
in hazards for the user and his environment.
►
Check system settings with automatic start-up function and assess
possible hazards for your application!
Both system settings are not activated in the factory setting. Before you activate the func-
tions, make sure that there is no hazard with your application. The operator must assess
possible hazards in order to guarantee the safety of users!
Unauthorized activation of the functions can be prevented with an ADMIN password (see
section
