Issue with PWR_IND Signal Provided by PCS3 Module | Thales IoT Developer Community

Sir,
I am using PHS-8P and PCS3 Modules with DSB Mini Eval Kit, and AH6-DSB75 Adaptor-1 Support Board.
When i try to Emergency Off the PCS3 Module by pressing RST Switch on the DSB Mini Board (This will nothing but pulling Low the EMERG_OFF Line of the PCS3 Module). but after this PWR_IND line remaining Low even if the PCS3 Module is switch off and all Communication on ASC0 Interface is closed.
As mentioned in the Hardware Description of the PCS3 Module, PWR_IND Line will be high when module is shut down. but in my case this line is remaining low always. so i have to do some other connection or is there any issue with the Module?
waiting for your reply...

Hello,
On AH6 this line is left floating. PWR_IND is an open collector output and it needs 100k pull-up resistor for indication to work properly.

Hello,
The same thing is working properly with PHS8-P Module. For PHS8-P module also i am using same AH6 and DSB-Mini board. PHS8-P also needs 100k pull-up resistor as per document.
so, my question is, if it is working fine with PHS8-P than why it is not working with PCS3 Module with the same support borads?
We have also tried with providing external 100k pull-up on this pin. but still same issue arises. When i provide Emergency OFF pulse, VExt is going low but PWR_IND doesn't go high.
Thanks & Regards,
Akshay
