If this reads near 0 ohms then you will need to remove the PWA from the heatsink and check for a silpad short. These can be accessed topside pwz probing T Pin 6 highlighted in pink and R Pin 2 highlighted in white.

If two of these MOSFETs are shorted then replacing them is all you will need to do to the amplifier section but you will need to check the power supply for damage. Look for metal shavings in the silpad insulator. Start by doing a thorough visual examination of the assembly for any sign of damage.


Walbert Secondary circuits. Single shorted output device with no other failures. Perfect Robert, this worked: This will help guide you to the trouble area. It should measure over 2K and rising as it charges up the capacitors. If any of these are damaged then you will most likely need to replace the following parts along with the ones already identified. Remove the supply, check the AC fuse and verify proper operation when plugged into the AC line.

Anybody have an idea? Its a test farm and just notice the project schedule is not displaying in PWA. The project is not checked out. Verify that the signal at Q Gate is a square wave at approximately KHz. Proposed as answer by Robert Dietrichs Monday, August 27, Wednesday, July 4, 4: The current draw should be less than 70ma.

Tuesday, April 24, Verify the switching waveforms at Q Drain pin and Q Drain pin are square and stable.

Shorted devices due to metal shaving contamination. Office Office Exchange Server. Verify that the signal at Q collector is a V peak to peak square wave. Tuesday, April 10, If this reads near 0 ohms, then check Q, Q, Q and Q for shorts, and replace the damaged parts. In this case the unit will power up successfully but will not work when driving a load.


Note that the ribbon doesn’t look quite right, because the edit and close button are both enable. Thanks, that is a much better solution.

Few quick questions though if ok to ask I’m “just an admin” for our PWA instance and guess this has to be done by some site collection manager or something? Included in each category are typical warning signs indicative of each as well as corrective actions implemented.

BoxNorthridge, California U. Is there any workaround for this? Eon Troubleshooting Guide E. My project schedules are showing blank lines.

This will allow the ssch to start switching. It is also worth noting that the bulk caps C and C can be damaged due to overvoltage stress if powered on at V with a stuck relay. New Product View Product Index.
