Slew Drive Manual for HUP’s (ACS 380)
Assistance Mode Displayed
When starting crane Assistance Mode was displayed on processor. Found 1 of the angle sensors on cathead was backed off 1/2″. Readjusted, all is working well.
Tomas says crane needs to see hook height, trolley position and jib angle. Can see on Erection Aid and J3 inputs (3211)
Crane will go into Assistance Mode if 1 of 4 sensors are not reading correctly. 1) Jib Angle – To check, go into Erection Aid (Menu 6), page 1
2) Trolley position – Menu 3211 and Input/Output J3 (not J2/J3)
3) Hook position – Same as above
4) Load on hook – Menu 3211 Input/Output J4 B400Nx

The 2 just means that it is the most recent revision (non structural) to make it compliant with different safety standards. In our case it would be OSHA.
