Air compressor model ingersoll rand nirvana N160-2s vsd problem for vsd fault 44

VSD Fault 22 -Current Overload, occurs after the drive motor has been in an overload condition for a period of time.

VSD Fault 33 -Rectifier Temperature, occurs when the input bridge heat sinks is greater than 194*F

Vsd fault 2 is a current imbalance. Check your current readings and compare them to those on the intellysis display they should match, also check for a imbalance in amps. After that it gets more complicated using board diagnostics etc

Vsd fault 7 is a fault with the hall effect sensors inside the motor, more than likely they will need replacing.

replace PTC Probe

check encoder

these compressors are costly even the parts to maintain.I would first check if you cooling fan for the vsd drive is working which is located in the electrical panel of the compressor.A failing fan or one that has failed would cause this fault

plz any one help us vsd 7 fault and the compressor does not start and the fault appears

Vsd 1 fault is over current, check if motor turns ok, if this is ok it could be a number of issues that will need to be diagnosed by an Ingersoll Rand technician.

VSD Fault 0 -DC Bus Over-Voltage
VSD Fault 1 -Over-Current

Vsd 23 is a motor under speed problem. Check motor turnes ok, if not it could be a number if faults including the hall effect sensor that detect motor speed, you will need to call a Ingersoll Rand technicion in to do a 348 diagnostic test.
