In the designed startup process for the ASU, it is not necessary to disable the interlocks, as this factor has already been taken into account. For example, in the case of an interlock triggered by high compressor vibration, a delay of 60 seconds is applied during startup; if high vibration occurs within those 60 seconds, the system will not shut down as a result of this interlock.
