Dear Team,
I hope this message finds you well. I am reaching out to you regarding a critical issue I am experiencing with the General Electric transfer switch model ZTG000A00060E.
Recently, I have noticed that the transfer switch is not transitioning from utility power to the generator and is displaying a "Mechanical Failure, Expect: SE, Actual: SN SEO" warning on the display. Additionally, I have made a change in the electrical configuration by cutting the 25ZZ cable to eliminate the SEO status. However, after this modification, upon attempting to start, the display shows "S1 OK, S2 STOP, Delay Time Remaining, Bypass," and after completing the countdown, the "Inhibited Signal" warning appears.
Attached to this email, you will find screenshots of the display that may provide further details on the states and error messages I am experiencing:
Figure 1: Warning initially found on the transfer switch.
Figure 2: Warning found on the transfer switch after disabling the 25ZZ limit switch signal.
Figure 3: Warning found on the transfer switch after pressing reset.
Figure 4: Warning found on the transfer switch after counting the time remaining. (After this, it returns to its original position like in Figure 1).
I would appreciate your assistance in diagnosing and resolving these issues with the transfer switch. Additionally, any guidance on how to correct the SN, SE, and SEO states to restore normal system operation would be greatly appreciated.
Thank you in advance for your prompt attention and assistance in this matter.

Did you RTFI? (Read The Friendly Instructions)
The transfer switch is trying to tell you that it has a mechanical failure.
1. Repair the damage that you have done. ( I have made a change in the electrical configuration by cutting the 25ZZ cable)
2. Inspect the limit switches and verify the operation of the switches to eliminate or repair a switch failure.
3. Examine the mechanical operation of the switch to determine the point of failure.
