INSTALLATION MANUAL
CAA480A
Elevator Controller
It is recommended that the voltage of the CAA480A's fl oor control relays do not exceed 24VDC.
It is very important that a trained and registered elevator service company connect any wiring
!
associated with any components of the elevator system, this includes the wiring of the CAA480A's
fl oor control relays.

FAIL-SAFE

When connecting to the elevator, we recommend that you use the fail safe method.
This ensures elevator operation regardless of the situation and gives the ability
to manually bypass all fl oor security in the event of fi re or system trouble.
This method is also used for Fire Control as well (see "Fire Control" on page 16).
Refer to Figure 5 for more details. To connect the CAA480A in fail-safe:
1. Connect the "COM" terminal of the desired fl oor control relay from the CAA480A
to the desired elevator control system fl oor button input terminal.
2. Remove the connection between the elevator car fl oor button and its corresponding
elevator control system fl oor button input.
3. Using a loop terminal added by the installer, connect the "NC" terminal
of the desired fl oor control relay from the CAA480A to the added loop terminal.
Then connect the elevator car fl oor button to the added loop terminal.
