Troubleshooting
1. Load is not moving up and down.
• Check for the leakages at fitting by using soap bubble test. Check for the leakages at the yellow and black pipe fitting.
• Observe for leakage noise.
• If the load is still not moving up and down then open the control box. Remove the solenoid valves, exhaust valve (D1, D2 and D3) and
inlet valve (M1, M2 and M3) and clean it. Fit the valves again in the same position.
2. Red light is blinking in the Control Box for more than 10 seconds after initiation or green button is turned ON.
• This is an indication of the Force sensor in the handle ADC value is not in limit or the Force sensor in the handle is out of range.
• Connect the control box to the system and open the GUI tool. Check for the Force sensor ADC value and make sure the value is 512+/-40.
• If any deviation in factory setting values, please contact nearest Ingersoll Rand office.
3. Load is not moving in up direction but moving in down position.
• This is a clear indication of the Max weight concept.
• Red light starts blinking when load is moved up in the control box.
• Connect the control box to the system and open the GUI tool. Check the weight of the load and change the Max value in the "Max weight"
box according to load to be lifted.
