  1. Elevator Controller Device

  2. Elevator Controller device (ECD) • The Elevator Controller Device is a stripped down version of the DCD. It is used for interfacing different reader technologies to the ECU. Up to 10 ECD’s can be connected to the ECU’s on a single site. Each ECD is home run back to a particular ECU and more than one ECD can be connected to the same ECU. • In most cases the ECD and the reader reside on the elevator car. Electronics Division

  3. ECD Spec’s • Input: 9 to 14 VDC (ECD will not operate below 9 volts) • AC/DC Transformer (ILCO P/N 003-101391) • 9-14 Volts regulated DC, 500 mA Transformer • OR Local Power Supply. • OR powered from SCU power supply. • Current: 100 ma (worst case current draw, board only) • Data Storage: None (Found on the ECU) • Operational Temperature: 14F to 104F (-10C to 40C)

  16. ECD Tech Notes • Up to ten ECD’s can be connected to the Local Data Trunk port of any ECU within a single SCU network. • Power for the ECD should be derived from an AC to DC converter transformer (P/N 003-101391) or a power supply. This will reduce the number of conductors that have to added to the elevator travel cable. • The ECD does not have a U3 RAM chip on-board. All memory functions are located on the ECU and not on the ECD. • The ECD does not come with a enclosure, make sure you order one.
