Abstract:
The MA5600T reports digital alarms because the original ESC values are different from the actual tested values.
[Fault Description]
Trigger conditions:
The control board is connected to the normal ESC and the software version is upgraded to V800R008C01SPC100.
Symptom:
The ESC generates alarms and the indicator (red) blinks one second on and one second off. The related information is as follows:

[Root Cause]
Whether the H801ESC dry contact generates alarms depends on alarm detection and control board configurations.
By default, the H801ESC dry contact does not generate alarms if a high level is used.
If the control board is configured to generate an alarm in low level, the H801ESC dry contact generates an alarm when it detects a high level.
If the control board is configured to generate an alarm in low level, the H801ESC dry contact does not generate an alarm when it detects a low level.
The default configuration of the control board is incorrect. As a result, H801ESC generates alarms continuously.
The configurations are as follows:
10 Arrester 0 1 | 11 Arrester 1 1
12 Arrester 2 1 | 13 Arrester 3 1
14 SW 11 1 | 15 SW 12 1
16 SW 21 1 | 17 SW 22 1
18 SW 31 1 | 19 SW 32 1
20 SW 41 1 | 21 SW 42 1
22 Outer Sensor Power 1
The detection values are as follows:
10 Arrester 0 Alarm 0 |11 Arrester 1 Alarm 0
12 Arrester 2 Alarm 0 |13 Arrester 3 Alarm 0
14 SW 11 Alarm 0 |15 SW 12 Alarm 0
16 SW 21 Alarm 0 |17 SW 22 Alarm 0
18 SW 31 Alarm 0 |19 SW 32 Alarm 0
20 SW 41 Alarm 0 |21 SW 42 Alarm 0
22 Outer Sensor Power Alarm 0
[Impact and Risk]
The H801ESC dry contact generates alarms after the ESC is normal. For details about alarms, run the corresponding command to query alarms.
[Measures and Solutions]
Recovery measures:
Run the following commands to modify default values of the ESC to recover the alarm.
