Vicario Weight on Remote
Tried to set weight on the remote, when doing so it would say to Early to DTA. Swapped load in with no luck. White and red wire needed to be swapped.

Slew drive stopping movement code 7510
Showed up to crane with 7510 slew drive code.
Saw 24 volt supply breaker tripped. Reset and took cover off of drive. No lights on can card. Gave it a wiggle and tightened plug and lights came on and drove stared working again.
Trolley drive faults when you trolley in or out
Drive starts up as normal, but when you try to trolley in or out, F0503 fault appears.
Bonfiglioli F0503 is an error code indicating a DC-Link Overcurrent fault
Found input power connector on the bottom of the drive was loose. Pushed it back in completely, and crane is working well.
Hup loses functions, drives shut down
Hup loses slew function sporadically, will sometime cause other drives to shut down with Cof fault. This is often an error with the slew motor encoder failing or shorting out. The drive sends a stop command AFE1 or 5091 to power down the drive which then shuts down the other drives.
The drive will often fault and shut down before registering a fault in the CCS. Check the fault history of the ACS380. If an encoder fault is present like 7301 – Motor Speed not detected,
Replace the motor encoder
If an encoder isn’t available you can remove the encoder wiring from the drive and it will default to estimated speed.
T85 starts and drives shut off
Slew, Trolley, and hoist drives begin start sequence, then power down. Check incoming power. It is possible L1 of the circuit isn’t there, but the other two legs will be the ones providing 48V and 24V to feed processor and start sequence. It will be backed up by the U100N not being powered.
Slow Trolley, Hoist
81K Crane hoist speed was slow. (no zones, Load plus was turned off) hoist speed was the same as if the micro movement button was pressed. The crane threw code E2647 DC undervoltage
Found the generator idle speed switch was at Low, flipped the switch to High restarted the crane.
Maintenance mode
Bringing the crane down in maintenance mode for checking the trolley or replacing hoist rope. It is not in the manual to do this. You need to push the escape and the down arrow on the LOGO to bypass all sensors then you will need to jumper the banana bar in the back.n This is jumpering the banana bar moment for trolley and hoist. You also need to either loosen the banana bar senors or unbolt them as it will crush them with the jib tip to the ground. That would also mean they need recalibrated.
From the picture it looks like we are jumpering 26T1 to NC-SLL and NC-SP to 26T1 and removing the blue and white wire out of NC-SLL
How to move trolley in mounting
When in mounting to move trolley you need to push the auxiliary button on the side of the remote wait for the Hydraulic pump to stop and then you have functions of trolley in. In order to get trolley out you have to by pass all the sensors on the LOGO by holding down the down arrow button and the esc button.
