Fast commissioning with factory setting

The vacuum suction nozzle is available with the following factory settings:
7
• Switching characteristics of the electrical output: threshold value comparator
• Switching element function of the electrical output: NO (normally open)
• Additional factory settings è Chapter 12.1
1. Mount the vacuum suction nozzle (è Chapter 5.1).
2. Connect the vacuum suction nozzle pneumatically (è Chapter 5.2).
3. Connect the vacuum suction nozzle electrically (è Chapter 5.3).
è The vacuum suction nozzle can be placed in operation.
If you do not wish to use the factory settings, you can teach a switching point for
the switching output (è Chapter 6.2).
The factory settings are not reproducible.

Function and application

The OVEM vacuum suction nozzle is intended for use to generate vacuum and is
only intended for use inside buildings.
The vacuum generated is used together with a suction gripper to create a force
that can grip a workpiece so that it can be transported. The vacuum suction nozzle
is available with a variety of pneumatic and electric switching functions.
The taught setpoint value for the generated vacuum is monitored via an integrated
vacuum sensor (-1P, -1N). If the setpoint value is reached or if it is not reached due
to malfunctions (e.g. leakage, dropped workpiece), the vacuum sensor emits an
electrical signal and the LED indicates whether or not the taught setpoint was
reached.
The supply of compressed air for vacuum generation is controlled by an integrated
solenoid valve. The solenoid valve can be supplied with two different switching
functions, NC and NO. The vacuum is generated as soon as compressed air is ap­
plied to the vacuum suction nozzle and the voltage is switched on (NC: -CE, -CN) or
off (NO: -OE, -ON) as defined by the switching function of the solenoid valve 2.
The integrated solenoid valve 1 can be used to control and generate an ejector
pulse to release the workpiece safely from the suction cup and to purge the vacu­
um rapidly.
