My DO880 card is showing all channels red ,energized channel yellow ,but no Do card fault ,fault is healthy only.
DO880 module channel will be red under loop monitoring fault. AC 800M HI DO880 module has got the loop monitoring function. If your cabinets/system is located at staging/factory without any load/outputs connected, you can disable the loop monitoring functionality by setting the following on DO880 module settings tab:
Trig limit open energized channel x - 0 mA
Trig limit open de-enrgized channel x - > 2000 ohm
The above settings will disable the loop monitoring functionality.
Yoou need to configure the below settings during commissioning based the output load/device type.
Trig limit open energized channel x
Trig limit short energized channel x
Trig limit open de-enrgized channel x
Trig limit short de-enrgized channel x
