3.7.5 Connection of an ejection system
If after an alarm it is necessary to activate an ejection system, this should be connected according
to its type and to the power supply box model.
- EJECT RELAY (J02 on ALM card, J1 on AL_ card) usable as ejection signalization through a
clean contact;
- EJECTOR NO (J14 on ALM card, not present on AL_ card) usable with single solenoid ejectors
or double solenoid ejectors (24 Vdc / 150 mA max), in combination with EJECTOR NC;
- EJECTOR NC (J14 on ALM card, not present on AL_ card) usable with double solenoid
ejectors (24 Vdc / 150 mA max) in combination with EJECTOR NO.
Refers to the Electrical Diagram and to the complete outputs description.
The EJECTOR NO output is activated (and EJECTOR NC deactivated) together with EJECT Relay
3.7.6 Synchronization
photocell
The Synchronization photocell is needed in cases where ejection high accuracy is required for
product in packs and correctly aligned on the conveyor belt.
Install the photocell as close as possible to the Detection Probe at the entrance or the exit in the
direction of transit depending on the ejection mode used.
The photocell must be connected to the PHOTOCELL input.
The photocell must be positioned at a height where the beam is always interrupted by the objects transiting on the
conveyor belt.

3.7.7 Ejection check photocell
The Ejection Check photocell is needed in cases where it is required to check that, during an ejection,
no product in packs is transiting over the ejection area.
The photocell must be connected to the EJECTION CHECK input.
The photocell shall be installed after the ejector and in a position that grant the correct activation by the objects passing
on the conveyor belt, and at the same height (respect to the transit surface) of the synchronization photocell.
