The tutorial below will show a connection with the current 114359 oval photocells.

The old photocells 104359 (Extel), or 114359 rectangular will be compatible with an AVLO electronic board.

The connection will be identical except for the photocells 104359.

Remove the shunt between GND and PHO from the circuit board.

Connect the +24V of the photocells to the +24V of the board.

Connect the GND of photocells to the GND of the board.

Connect the NC of the RX photocell to PHO on the board.

Connect a shunt between GND and COM on the receiver photocell.

Remove the shunt between GND and PHO from the circuit board.

Connect the + of photocells to the +24V on the board.

Connect the – of the photocells to the GND of the board.

Connect the NC of the RX photocell to PHO on the board.

Connect a shunt between – and COM on the receiver photocell.
