Straight passing through:

A pallet on Highway is approaching. The pallet activates sensor B1 which
actuates stop A1 which stops the pallet if function is occupied. Sensor B3
and B4 supervise the function area. If both sensors gives low signal the
area is empty.
Sensor B5 and B6 indicates if the stop is activated or not.

Function occupied:

Before a pallet is let into the function the previous flow must be finished, the
arm to be in right position and downstream receiver be ready to receive.
Example: Previous flow was straight. Pallet enters on Satellite (M) to be
merged. Stop A1 block the flow, then wait until B3 and B4 do not detect any
pallets. When downstream Highway is ready to receive, then pallet on Sat-
ellite (M) is released by stop A2.

Sensors:

The primary function of In position sensors (B1, B2) is to detect pallet
placed in specific position. Additionally the sensors are placed in the way
they can actuate stop (open/blocking) before pallet gets into contact with
the stop up to conveyor speed 10 m/min. (if the speed is higher, an addi-
tional sensor placed upstream is needed in order to have time to actuate
before the pallet reach the stop). Primary and secondary sensing route
sensors facilitate handling trains of pallets which decrease the cycle time.

RFID:

The RFID head can be used to read/write RFID tag data on pallet. The data
can be used to take flow decisions at crossings, for example at stop A1.
The RFID head shall be mounted outside the module, before the stop A1.
