Power Protection mode question

how do we know the power supply is toast vs in power protection mode?

from reading power protection mode cant occur in low power mode.


so protection happens at 95A. in lower power mode it gets to max 15A. my breaker. in high out 1 it gets to 95A so i feel the only way it can happen is in high output mode.

can someone confirm

Thanks
sb

ok so let me clarify more

i have an older model
s11
19thz on high power and 17thz on low power mode
19.5thz @1365 watts
17thz@1120

So i have a power meter on it the s11 and i see on power on it goes up to 1450 watts then lowers to 1140 watts and stays
its goes to 9.7amps

also on the bitmain website it says under power supplies support
1. Generally if your miners requires more than 1200 watts the socket must deliver 220v.

Google says
yes i can make sure its on 15 amp circuit and nothing on it with 14g cable.

Modern circits are 15amp and max load of 1800watts

thanks for the help so far.

The previous owner never has an issue running them on 120v. he said he did for over 9 months then got 240v

could it be just the Ps time to go?

Hello

Setails
Home Eclectic - 120v
Both devices are in the garage on different circuits. i have made sure.
Using low power mode on both devices. i have made sure
Using 14g cables for power cables
using serge protect 500jouls with 14g cable

I purchased a used t15 and s11.

I ran the s11 first 24 hours. no issues with other devices running at once dryer, AC washer. no space heaters in the house.

I then power on the  t15 and let it run together. everything is running fine for over 24 hours. in that time dryer, stove, AC all been on/off in the house

I am getting 38thz on slush pool.

Issue:
I wake up today and T15 is offline. the device does not power on. no fan spinning. nothing.

Troubleshooting
tried different power cable.
tried different wall outlet in the home away from garage.

I have verified the outlet is working with other devices iphone charger, volcano vap, laptop charger. outlet is working.
Breaker is not tripped
No power serge or have had them at my house. living hear for a while.

S11 is still running to this moment no issues

Research done
I fine maybe the power supply has entered power protection mode and need to be set to bitmain.

or is the power supply just died from it being an old unit?

please advice would be great.
