Mechanics
ATTENTION
►
In case of improper use of manipulation of the device, there can be
property damage to the connected vacuum pump or vacuum
apparatus!
Operate the device only according to the operation manual and the instructions in the opera-
tion manuals for the connected devices!
Operation with overpressure is not permitted with the device.
Solid and liquid materials in the gas to be conveyed can compromise the function of the sen-
sor. Prevent the penetration of solid particles into the vacuum apparatus.
2.5.5
Vacuum
WARNING
►
Hazard due to sudden ventilation of the vacuum apparatus.
►
Due to sudden ventilation, the vacuum apparatus can explode.
►
Prevent sudden ventilation. Check the pressure in the vacuum
apparatus before you disconnect the pneumatic connections.
The vacuum apparatus can also be under vacuum when the device is
switched off.
Glass equipment is especially at risk. Make sure that it is vacuum-proof and non-breakable!
2.5.6
System functions
The following settings for the "control systems" must be assessed separately for particular
vacuum applications,
see Chapter 6.2.6 System
"Allow ventilation"
When this function is activated, it is possible that ambient air will get into the applications.
This can cause uncontrolled reactions.
Note that an inert gas must be connected to the ventilation valve if necessary.
By activating the function, gas, possibly ones damaging to health, can escape from the
application into the environment!
"Auto Start"
If the "Auto Start" function is activated, the device starts automatically after
a power failure or when the power switch is 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 the ADMIN password,
