IDEC FA-2J PLC CEC/CEV/HUT TROUBLESHOOTING GUIDE
ALARM SIGNALS
1. The PLC sends alarm signals to the Alarm Terminal Box that is usually located above the control panel. If an alarm signal is not being sent verify the wiring from the Relay Output Module, PFJ-T081U, to the Alarm box is not loose. Replace the individual relay, RSIS-FA-1, for the alarm point that is not working. If the Red Output LED is not on for the Alarm Output then the PLC does not recognize this as an alarm condition. Check the PLC Input Signals to be sure the incoming alarm signal is working properly.

2. The number shown on the right side of the display indicates the PLC Error Code. A value of 1 or 5 is normal. Any value that is 80 or above is going to require some work to correct. The PLC should be powered down and the memory pack replaced with an updated program version to try and clear the error. If that fails the CPU may need to be replaced. Please call Hyland Automation Controls, Inc. at 781-229-5600 for assistance before replacing the CPU to try and determine the problem. A CPU problem is extremely rare! Follow the Error Code instructions in Step #3 on the following page.
3. If a laptop PC is used in place of a Program Loader/PROM Burner then follow the instructions in the SOFTWARE ASSISTANCE, CLIP 6.0 Section found later in this manual. Go to the Ladder Monitor using Idec's CLIP software. Press the 1 Key to go to Screen #1 and press the Function Key, F1 MONITOR, to activate the PLC Monitor. The Pushbutton inside the enclosure must be pressed so the PLC will communicate at its default of 9600 Baud, 8 Data Bits, 1 Stop Bit, and Even Parity. Press the 2 Key to go to Screen 2 and press Function Key, F4 ERR READ, to read the Error Code. A value of 1 or 5 is normal. Press F5 ERR XCEL to try and clear the alarm. Any value that is 80 or above is going to require some work to correct. The PLC should be powered down and the memory pack replaced with an updated program version to try and clear the error. If that fails the CPU may need to be replaced. Please call Hyland Automation Controls, Inc. at 781.229.5600 for assistance before replacing the CPU to try and determine the problem. A CPU problem is extremely rare!
4. Binary Cumulative Error Codes:
Note: The Program Loader commands in the right column can not be used with the laptop. Use the Function Keys from Screen #2 to read and cancel the error codes.
