Arrow setting up
1) – Direction arrows (default)
2) – Next direction arrows (instructions below)

Next Direction Arrows enabled from input
Arrows light up only on the position indicators with the “NEXT DIRECTION” input powered.If the DEUM Encoder is used, please refer to the relevant manual

Next Direction Arrows locally programmed
Through the addressing procedure one can permanently assign to each indicator the information of the floor on which it is mounted; in this way, next direction arrows only light up at the floor where the elevator car is positioned.

Addressing procedure

1) – Connect all position indicators to the ENCODER or PLAYBOARD controller.
2) – Position elevator car on the floor of the Display which needs to be directed.
3) – Verify that the characters/numbers/letters visualized are the desired ones.
4) – Press and hold the ADV key and wait for the display to flash for 3 seconds to confirm.
5) – Repeat procedure for each floor.
If the DEUM Encoder is used, please refer to the relevant manual

Set up the display delay of floor change
The display delay helps avoiding visualization errors during floor change.
Associate the floor position indicator with the duplex controllers
The parameter allows to assign the display (floor) to a unique controller. The Duplex-Light typology includes 2 controllers with a single BDU line and a maximum of 2 displays at the main floor.
This parameter can only be set with the CAN protocol on the Pitagora 4.0 system.0) – To be associated with the lift car position indicator.
1) – The display will show the information of the MASTER controller.
2) – The display will show the information of the SLAVE controller.
