GE / IP FANUC Series 90/30 In Stock
This troubleshooting guide is a test of a GE Fanuc IC660BBA101 Genius Block.
In order to test this, you are going to have to test all the functions and features of the block. This is a resistance thermal protector. It has 6 Inputs, Analog reading, and you are going to test the physical
monitor port, which is for the IC660HHM501 Hand Held Monitor to be able to communicate to the Genius Block. (see below)
You’ll also be testing the Serial Ports, so that the Genius Block can communicate to the Bus Controller, which is connected to the Central Processor and your software.
In this illustration to conduct the test you need to use Proficy Machine Edition Software (see below) and you’ll be using all the inputs.
You will start with Configuring the block using the hand-held monitor, HHM501 (see above) and the first thing you are going to check is the settings. In this illustration the the factory settings are being used on the block ie: Factory settings and scalings for the block. Note that it is not recommended that you change your settings if its a working block.
This is just what is being done to do this test. So you are going to click OK and so you know its communicating at 153.6K standard baud rate. Go to Configuration F3, Program Block ID F1. And what you are doing here is selecting a block number that is the same as the block number you have configured in Proficy Machine Edition.
And the reason you do that is because when you get to the software and CPU end of things in Run Mode, it is able to turn on your I/O Enabled Light. And this tells you that now this Genius Block is communicating or talking with the Bus Controller and also the CPU through the Serial Port. (see below)
Next you are going to test the Serial Port (see above) to make sure that its working, and it is. You know that the monitor is working because you have been able to program it using the handheld monitor.
The next thing you want to do is check your configuration.
So that is F3, F2. and you do want to report Faults for your purpose. You do want all channels active because you will be testing all channels. And the rest of the settings are the factory settings: celcius, platinum linearization. 100 Ohms is the resistor that is illustrated here and it is actually a 100 ohm resistor that is just going to test each channel (see below).
So the 100 Ohm resistor, that is ok. 400 millisecond input filter time, configuration protection is disabled. If yours is enabled, and you have your configuration protector on, then you should leave it on.
The next thing you want to do is analyze the block. So F2 and then F1 to monitor the channels. You can only monitor two channels at a time or 2 inputs at a time, if you will, input 1, input 2. What you are going to do is you are going to probe each channel using the resistor and following is the terminals and channels used to get the readings in this illustration.
Now all of the channels are being configured the same, so you are expecting a very close result for each channel once they are probed with the 2 ends, the two leads off of the resistor.
For Channel #1, you are probing terminals 9 and 10 and a reading of 14.6 is returned, so pretty close
to 15. Channel #2, terminals 13 and 14. 14.9 is returned. Again, very close to 15. Next you want to check channels #3 and 4. So you are going to toggle over to 3 and 4 pressing F1. So yyou are going to go ahead and probe channel 3.
You are touching terminals 13 and 14, again, the you should get the same figure. If you do this is good to see. Now 21 and 22 allows us to probe channel 4, again 15. and you are going to toggle over one more time so you can read inputs 5 and 6.
So next is channel 5, and you are probing terminals 25 and 26, it is a little difficult to keep them in there, but in this illustration it came out very close to 15. And channel 6 and probing terminals 29 and 30. They are all within the 15 degree Celsius range, which is good.
You also want to take note that connected to the serial port is a bus controller, and that part number is IC660BEM331. It is connected to an IC693CHS397 5-Slot Rack. Using a IC693PWR330 Power Supply and an IC693CPU374 for this test.
Now if you have any problems with your Genius Block, like if you power it up and you don’t have lights that come on. Another thing is that you go to the Configure ID screen on your hand-held monitor, that’s the IC660HHM501, and instead of getting a block number you get a question mark, where it is unable to store a configuration.
