SH1 status test on active

¿Qué significa 231-E004 ?

This error indicates that the measured status of the '-SH1' signal is 'high' level, but it is expected to change to 'active' ('low' level) as the MC (Machine Control) is no longer triggering the corresponding watchdog. This points to an internal software error or a hardware defect preventing the '-SH1' signal from transitioning correctly.

• The measured status of the '-SH1' signal is 'high' level, but it does not change to 'active' ('low' level).
• MC is no longer triggering the corresponding watchdog, expecting '-SH1' to go 'low'.
• Internal software error.
• Hardware defective, specifically related to the '-SH1' signal path or watchdog monitoring.

1. 1

   Check the wiring connected to the '-SH1' signal input for any loose connections or damage that could prevent it from going low.

2. 2

   Monitor the status of the watchdog signal from the MC to confirm it is not being triggered when this error occurs.

3. 3

   Verify the software version of the controller and update it if known bugs related to SH1 signal handling exist.

4. 4

   If possible, perform diagnostic tests on the hardware associated with the '-SH1' signal and its watchdog to identify any defective components.
