Powering and reset
After a power failure or a temporary corruption of data, the M2250 attendant
console is reset automatically.
If a permanent fault condition is detected, the console enters the maintenance
mode (Position Busy), and a failure message is displayed on the LCD screen.
Note 1: The failure code format is XXH, where XX is a two-digit
hex-code indicating where the fault has been detected. Refer to Table 12
on
page 87 for explanations of the failure codes.
Note 2: When the BLF/CGM is attached to the console, an additional 16
V DC power supply (A0367601) is required for optional backlighting.
