Plase help!VSD fault 2 Problem with Ingersoll Rand Air Compressors nirvana n37 37kw


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

Please!!!VSD fault 7 and VSD fault 1 Problem with Ingersoll Rand Air Compressors nirvana n37 37kw. thanks!


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

Yes, the control board may be bad . Ihave attached a procedure for checking the hall effect sensors, some of which you will not have the special tool needed to preform all the tests. However it will allow you to check the control board which may be bad causing your problem.

VSD FAULT DIAGNOSTIC GUIDE
10 Revision 001 - March, 2002
Appendix 4 - Hall Effect Sensor Checks (Four Part)
1. Isolate the compressor from the main incoming voltage supply. Lock and tag the
isolation switch in the open position.
2. Allow 15 minutes for the VSD to discharge capacitors.
3. Open enclosure doors to expose the VSD.
4. Check with a suitable meter that all voltages have dissipated before beginning work on
the VSD.
5. Remove rear cover of drive motor to permit rotating by hand.
TEST 1
6. Disconnect Hall Effect Cable from P4 on the Control Board, plug type is DB9 Type.
7. Inspect cable pins and matching receptacle connections for damage or bent pins.
Remove cover of plug and inspect solder connection of the wires for damage.
9. Inspect entire length of the cable for damage. If cable and connections are in good condition,
proceed to Test 2.
TEST 2
9. Confirm supply voltage to the Hall Effect Sensor is present using a digital multi-meter.
10. Disconnect terminal strips P1, P2 & P3 from the bottom of Control Board.
11. Trip and switch off MCB2 and MCB5 to prevent the SGN Intellisys from powering up.
12. Re-connect main incoming supply voltage to the unit. Isolation contactor KM1 should remain
de-energized and the VSD should only receive control power. Caution must be taken as the
panel has voltage present.
13. Set digital multi-meter to DC Volts.
14. Connect Black probe of multi-meter to either of the 2 pins of P16.
Note: P16 is located on the Control Board, slightly less than half way down and towards the left side.
P16 is marked and described as 2 small bare pins. P16 is the ground connection for the Control
Board.
15. Locate the small transistor just above Pin 3 on terminal strip P1. The transistor has 3 pins on
the left side. The pins are numbered 1 at the top, 2 in the middle and 3 at the bottom.
16. Connect Red probe of multi-meter to Pin 3. The voltage should be between +11 and +14 Volts
DC.
17. If voltage is not present, replace the Control Board.
VSD FAULT DIAGNOSTIC GUIDE
11 Revision 001 - March, 2002
TEST 3
17. Connect special adapter XXXXXXXX between P4 on the Control Board and the Hall
Effect Sensor Cable.
19. Set digital multi-meter to DC Volts.
20. Connect Black probe of multi-meter to either of the 2 pins on P16.
21. Connect Red probe of multi-meter to Red wire of the adapter. Rotate motor by hand and
observe measurement. The meter should read between +10 and +12 Volts DC.
22. Repeat the test with the Black wire of the adapter. The meter should read between +10 and +12
Volts DC.
23. Repeat the test with the Yellow wire of the adapter. The meter should read between +10 and +12
Volts DC.
24. If voltage does not rise to between +10 and +12 Volts DC for any of the 3 sensors, replace the
Hall Effect Sensor Assembly.
TEST 4
25. Set digital multi-meter to Ohms.
25. Connect multi-meter between Purple and Green wires of special adapter XXXXXXXX. The meter
should show a resistance value of approximately 150 Ohms ± 20% (New Hall Effect Sensors)* at
70° F (20° C) ambient temperature.
27. If correct value is not confirmed, replace the Hall Effect Sensor Assembly.
Note: Two temperature ranges (130° C and 150° C) of Hall Effect Sensor have been used. Typically,
the 50/60hp (37/45kW) units use a 130° C sensor and the 75/100hp (55/75kW) units use a 150°C
sensor. All sensors have a small band near the sensor end of the cable.
The 130° C sensor has four digits such as 6622 on the band. The 150° C sensor could have either a
four digit number with a star on each side (*6752*) or a four digit number followed by a star and the
letter E (6752*E) or a four digit number followed by an E (7652E).

We have ingersoll rand VSD compressor Unigy L AR model IRN11K-10-500-H, the machine has got brake down due to some electrical fault and the technician reported that there is an electronic drive failure and...


These VFD or VSD units do experience drive failures. If it is not covered under warranty it will be and expensive repair. You might try calling the IR Phone # that should be affixed to the unit. Some times they might recommend replacing an electronic board and supply it to you. Other than that replace the drive.

Output fuse blowing


I don't believe this unit has an "output" fuse. The fuse is in the power line input typically.

When it blows there is usually a defect in the power transformer or the input rectifier and or filter capacitors.

Fixya is very imprecise on the model numbers of the postings here. If your unit is a tube type, then check the fuse to see if it is silvery inside. This indicates a dead short. Most of these use solid state rectifiers so suspect a shorted diode or filter cap.

You need a bit of trouble shooting electronic skill to work on this. Remember that vacuum tubes run at high voltage so great care must be used when working on these.

Bad output IC or voltage rectifier are the most likely at fault.

Subwoofer blows the internal fuse when receiver is turned on


possible solution - this can be caused by a fault in the receiver unit. the sub has a triac 'high side switch' circuit that can cause the fuse to blow if it doesn't get a good switching signal e.g. if the receiver power supply is not running at the full voltage. check the plug pack wire for damage, check the 12v input area on the receiver board for dry joints, particularly the power input socket. hope this helps.-pj
