Error Message
The error message can be obtained in two ways: by reading the appropriate display on the hand set display or by observing the fault codes issued by the status
LED.
HAND SET DISPLAY DIAGNOSTICS
Faults are displayed in the Faults menu.
LED DIAGNOSTICS
During normal operation, with no faults present, the status LED is steadily on. If the controller detects a fault, the status LED flashes a fault identification code
continuously until the fault is corrected.
The status LED uses a 2-digit code. For example, code "1,4"—UNDERVOLTAGE FAULT,appears as:
