Wifi crane model serial #
Wifi PW: IxonFMGru*23
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.
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.
FM Gru Electrical Schematics
When look at a component in the electrical cabinet or wire, the number indicates what page in the schematics that the component can be found at. For example, 6U1 is the hoist inverter (VFD) found on page 6. Wire #1503 is found on page 15 and is wire# 03 in a sequence.
S=Hoist (pg 6)
R=Slew (swing) (pg 9)
C=Trolley (pg 12)
F=BrakeKL= Safety validation for the drives
FM Gru will not start
Crane will not start with remote control and display shows “Remove Inserted Commands”
A joystick is out of adjustment and not returning to neutral. Can try and clean connections on the back of joystick, or use app to recalibrate remote.
FM Gru won’t start
When trying to start crane, the PLC and the load sensor were not turning on. The top light on this device was flashing red.
This is an electronic circuit break. Found the short, and corrected. The red light can be pushed to reset.
Crane load indication accuracy
1917.46(a)(1)(ii)
The accuracy of the load indicating device, weight-moment device, or overload protection device shall be such that any indicated load (or limit), including the sum of actual weight hoisted and additional equipment or “add ons” such as slings, sensors, blocks, etc., is within the range between 95 percent (5 percent underload) and 110 percent (10 percent overload) of the actual true total load. Such accuracy shall be required over the range of daily operating variables reasonably anticipated under the conditions of use.
FM Gru 1589 Relay Explanation
Rundown of relay to contactor logic
Contactor 34K1 controls valve bank coils.
Y1 Mast down
Y2 Mast up
Y3 Jib up
Y4 Jib down
Relay bank
36K1-5 relays
36K1 Mast down (34K1-Y1)
36K2 Mast up (34K1-Y2)
36K3 Jib up (34K1-Y3)
36K4 Jib down (34K1-Y4)
36K5 Control relay (supply)
FM Gru 1589 will not raise the jib in erection mode
Tried to erect 1589 and the jib would not raise. Checked hydraulic pump, and it was building pressure, but the coil to open the valve bank was not being activated.
Contactor was switching to open, but the control relay for the valve was bad.
Light would turn on the face of the relay, but would not actually switch. The orange screw could be turned to manually make the switch and the jib would go up. Replace relay.
FM GRU 1589 Limits Hoist and Trolley
This is only for the Upper and Lower hoist limits and the Inner and Outer Trolley Limits
You need to set the trolley limits before the Upper and Lower hoist limits!
—– Limit calibration —–
With machine in work,
press the radio control buttons A and D simultaneously for at least 5s until the radio control buzzer sounds.
At this point the machine goes into calibration mode and the radio control screen changes showing the current maximum and minimum limits.
It is possible to move the lifting and trolley axes WITHOUT LIMITATION to bring them manually to the maximum and minimum positions.
Once the limit position has been reached, by keeping the corresponding button pressed for at least 3s, the quota (minimum or maximum) will be fixed to the current position of the axis
and to the value displayed by radio control.
The keys are assigned as follows:
– key A for minimum lifting limit (LOWER LIMIT CLOSEST TO GROUD)
– key B for maximum lifting limit (UPPER LIMIT CLOSEST TO JIB)
– C key for minimum cart limit (INNER TROLLEY LIMIT)
– D key for maximum cart limit (OUTER TROLLEY LIMIT)
The LEDs positioned above the keys indicate whether the limits calibration has been carried out (LED on steadily) or not (LED off), respectively at the minimum and maximum lifting and trolley levels.
