The board controlling the motor drive is located inside the front upright
interrupted, the error code should be identified by means of the status LED. 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 of using the key switch
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:
