Connection & speaker
Connect the nVOICE to the Movilift CANbus and wire a 4–8 Ω 1–5 W loudspeaker (65 mm opening, 20 mm depth). Supply 12–24 VDC. Insert a micro SD card (4 GB, FAT32) holding the WAV/PCM audio files.
Diagnostics (blink codes)
The 2 diagnostic LEDs report faults by a number of blinks followed by a 1-second pause:
- 1 blink – file access error
- 2 blinks – error reading parameters from Flash
- 3 blinks – error writing parameters to Flash
- 4 blinks – digital-trimmer setting error
- 5 blinks – floor to announce out of range (-3 to 31)
- 6 blinks – no CANbus activity from the board for over 3 s
