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

Adjusting Moment Limit Switch on HDT 80

On the rear of the mount for the dynametric ring located at the rear of the crane, is an adjustment bolt.  On the side of the mount, there is an access plate to reach the bolt head.  Remove plate, and adjust screw.  Clockwise will allow load to mover further out on the jib, Counter-Clockwise will cutout movement sooner.
