Customer called and said stopped mid-pick while trolleying. Customer was able to hoist and swing, but no trolley. Lowered load and cleared the hook. Drive showed FST.
Went to Erection Screen and all sensors and switches were open. The thought was that we lost +24V from transformer. Customer went to get a meter, but didn’t work. Got a 2nd meter and turned crane back on. Erection Aid read correctly. Trolley drive was flickering between FST and RDY. Disconnected G33, and drive went to RDY. Power cycled the crane and all works at this time.
