Board Alarms
If drive is interrupted, the error code should be identified by means of the status LED (fig. 6. ref. 16). In the absence of
malfunctions, the status LED is steadily on while the machine is in operation. If a malfunction is detected, the status LED provides
two types of information, a slow flash (2 Hz) or a rapid flash (4 Hz) to indicate the severity of the malfunction.
Malfunctions with a slow flash are cancelled automatically once the malfunction has been repaired and the machine functions
normally again. Malfunctions with a rapid flash (* in the table) are considered more serious. The machine must be turned off using
the key switch (fig. 6 ref. 14) to reset operation after repairing the malfunction.
The indication of severity remains active for 10 seconds, after which the status LED flashes constantly showing a two digit malfunction
code until the repairs have been carried out.
For example, error code 1,4 is displayed as follows:
