6- ELECTRICAL CONNECTIONS

6.1 ELECTRICAL SUPPLY

The ejector in order to meet the requirements of the automation is fitted out with an electronic circuit
(beam) set up on the ejector's body.
Ä Voltage used: 24 V DC regulated at +/- 5 to 10 %.
The electrical beam is interchangeable, even in case of trouble and it is connected to the vacuum
feeders by two M12 connectors.
ƒ «INPUT» connector: it supplies the vacuum switch and resends the information «vacuum reached»
to the automaton.
ƒ «OUTPUT» connector: it supplies the solenoid valves of the ejector and selects the «Suction», «Shut-
down», «Blow-off» modes.
NB: emergency stop shuts off the outputs and lets the supply on the inputs in order to keep the infor-
mation about vacuum level.
