SOURCE: Compressor run 10 min then

OK I am guessing this is a modular drive. Fault 39 is an IGBT fault on phase U and 40 is an IGBT fault on phase V. Unless you are experienced it's best to have a qualified service tech do the repair. However here are my thoughts. The IGBT fault may be caused by a dirty air filter located in the side panel. It's some where around 10" x 12". If the electrical panel filter is dirty you don't get enough cooling. The IGBT's get hot and over temp. causing the above fault codes. Check the filter and replace if needed. Next in top of the electrical and drive compartment is a fan. Make sure it is operating properly. If the fan is not operating again you get no cooling air for the IGBT's. I have seen customers open the panel doors and put a large fan blowing on the drive to cool it. I don't recommend this due to the fact the air is unfiltered and can get dirt into the drive and cause damage!. However some customers have to run and take the chance. There are also other items that can cause these faults. But as I said before determining whats wrong can be very technical. Does the display show any other # after fault 39 or 40 like 39 - 3 or 40 - 2. If so this gives additional info on the fault and tests to perform like checking the ID board or interface board. Good luck hope it's a filter.

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).

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 23


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.
