Hello, dear friends!
1.The ALARM port (RJ45 port) on the front panel of the control board is connected to a network cable, which must be a straight-through cable whose wire sequence is orange, blue, green, and brown.
2. The wire sequence of the other end of the network cable is as follows:
Green: 0-door status sensor alarm
Blue: 1-lightning arrester alarm
Brown: 2-MDF alarm
The blue, green, and brown twisted pairs can be connected to the power monitoring system to monitor the power by digital parameters.
3. Connect the twisted pairs (brown for example) to the power monitoring system, check whether ESC digital parameter alarm is generated, and query the valid high level and low level of digital parameters.
huawei(config-if-h831vesc-0)#display esc environment info
EMU ID: 0 ESC environment state
---------------------------Digital environment info-------------------------
ID Name State Value |ID Name State Value
0 Door Normal 1 |1 Arrester Normal 1
2 Wiring Alarm 1
----------------------------------------------------------------------------
If an alarm is generated, the high level and low level of digital parameters are incorrectly defined. In this case, correct them to clear the alarm. The low level is presented by 0 and high level is presented by 1.
huawei(config-if-h831vesc-0)#esc digital
{ digitalid<U><0,3> }:2
{ available-level<K> }:available-level
{ available-level<E><low-level,high-level> }:low-level
Command:
esc digital 2 available-level low-level
After modification, the alarm is cleared. That is, VESC is used for power monitoring.
I hope it will be helpful for you. Thank you!
