Problem:

Why do I get a Main Console Trouble?
How do I clear a main console trouble?
What does it mean when Main Console Trouble LED is lit up?
 

Environment:

• ECC-50/100
• Main Console
• System Trouble
• Default ECC

Solution:

1.- Confirm customer has resistors in place:

Terminal Blocks with 1 resistor

• TB4 > 4,7K Ohms (On the in terminals if not being used, on the out terminals if being used)
• TB5 > 4,7K Ohms (On the in terminals if not being used, on the out terminals if being used)
• TB19 > 4,7K Ohms (On B+- Terminals if not being used, at EOL if being used)
• TB20 > 15K Ohms (On the out Terminals if not being used, at EOL if being used)
• TB21 > 15K Ohms (On the out Terminals if not being used, at EOL if being used)
• TB22 > 15K Ohms (On the out terminals if not being used, at EOL if being used)
• TB23 > 4,7K Ohms (On B+- Terminals if not being used, at EOL if being used)

Terminal Blocks with 2 resistors 

• TB6 > 4.7K (One on terminals 1 and 2, another one on terminals 3 and 4)
• TB7 > 4.7K (One on terminals 1 and 2, another one on terminals 3 and 4)
• TB8 > 4.7K (One on terminals 1 and 2, another one on terminals 3 and 4)

2.- If the trouble hasn't cleared after checking resistors > Load Defaults > Send to Panel on the ECC on the following categories:

• General/NAC Options
• Address Assignment
• Message Buttons

3.- Re-Program the ECC-50/100 after loading defaults on the following categories:

• General/NAC Options
• Address Assignment
• Message Buttons

Send to Panel each configuration and log off twice when finished.

4.- If loading defaults doesn't clear the trouble:

• Turn SW3 to the down position
• Wait 30 seconds
• Turn SW3 back up
• Power the ECC-50/100 down for a minute
• Power unit back up
