Elevator Controller Device

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. 2 Electronics Division

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 m. A 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) 3

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 U 3 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. 16
