Igo T85A, MA13, MA21 V3 Codes
Adjusting Brake and Microswitch for Weathervane on Tower
Top Zone Igo T85A
Crane would not accept P1 or P2 in Top Zone.
Need to verify that the crane is reading the correct angle position and it moves with crane. This is displayed on the remote by pressing the arrow keys. If not, need to redo 1.5 times rotation and set origin, reference manual if needed.
Per Tomas, Set P1, set P2 and then press <ENTER> through Stopping Angle. Press <ESC>, <ESC>, ESC>, and turn of remote and then crane power. Restart crane, and it should work.
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

Trolley would not work on Igo T85A
Hoist and slew would work, but no trolley. Obf was displayed on trolley drive. Found trolley discharge resistor was damaged and broken. Ultimately, was an input power problem that damaged trolley resistor.
Igo T85A Horn Honks when trying to Telescope up
When trying to telescope up, horn would honk. Would go down, but not up. Went through erection aid and all looked good. Needed to readjust brake microswitch on telescoping drum.
Adjust microswitch by loosening locking nut and running down adjustment screw until “H” light comes on in CAN Open module (U213X). Back off screw, just until the light goes off.
Trolley stopped working on Potain T85A (27148)
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.
