A circular dependency exists between M1M3 Support System Critical Failure and TMA Block Motion PILs signal. The problem is that M1M3 fails to transition from standby into a disabled state when the TMA Block Move Pils signal is on and continues to produce (interrupt) M1M3 Support System Critical Failure when in standby.

To get out of that, one must bypass TMA Motion Block, let M1M3 SS transition to disable, reset M1M3 Critical Support System Failure, and then unbypass TMA Motion Block. Or ignore TMA Motion Block in CSC (through a configuration file), let it transition to Disabled, so M1M3 Critical Support System Failure will be inactive, and reset the M1M3 Critical System Failure in Pils. Then the TMA Block Move signal will go away.

This improvement shall ignore the TMA Block Move signal in M1M3 CSC when in the Disabled state. The one doesn't have to change Safety settings, just transition M1M3 CSC to disable, reset M1M3 Critical System Failure in Pils, and continue with the mirror operation.
