Subject: TH crane main hoist B starting delay issue appears again. 

TH crane main hoist B starting delay issue appears again this Thursday. It is about 1 minute waiting time after power on the crane. this is an old problem we spent so much time in investigation and tried solve during last summer and fall. During this period, the delay time became shorter and the problem disappeared completely in November. It worked fine since then  until this this day. TH crane still works fine other than it. I will watch in this issue closely.
