E-Stop Engaged

This message is not necessarily an error, but you might receive other related errors if the E-Stop is showing to be engaged, especially when you attempt to execute a machine function and the E-Stop button is not engaged (released and extending completely forward).

Possible Causes of a False E-Stop Engaged Message:

User Interface Harness not plugged in correctly at keypad or control PCB (most probable)
faulty circuitry on Main PCB
defective E-Stop switch (least likely)

Troubleshoot a false E-Stop engaged error following the steps described in the table below.

First, remove the base cover and locate the E-Stop LED located at position D49 on the main PCB. Observe the condition of this LED (on or off) as you perform the following troubleshooting steps (machine must be turned on with the AMAYA OS software loaded):

Step	Action	LED (D49) Condition	Next Step/Solution
1	Inspect the user interface harness and the harness connections. Make sure the harness connections are secure. Disconnect and reconnect both ends of the harness and make sure they are both securely connected.	OFF	Problem was a loose or improper connection.
1		ON	Replace the harness if kinked, chaffed or connectors damaged or worn. Otherwise go to step 2
2	Disconnect the harness from the back of the user interface.	OFF	Replace the user interface assembly
2	Disconnect the harness from the back of the user interface.	ON	Go to Step 3
3	Select the "Keypad" tab in the AMAYA OS "Maintenance" menu. Look at the "E-Stop Button. This button and the LED at D49 should be at the same state, ON or OFF.	Same as E-Stop button in keypad test	E-stop switch is defective, replace it
3		Different State	Possible fault on the Main PCB. Contact Melco Technical Support.
3	Reconnect the harness to the back of the user interface and disconnect the user interface harness from the main PCB.	OFF	Replace user interface harness
3		ON	Go to Step 4
4	Close the AMAYA OS program on the computer.	ON	Replace Main PCB
4	Close the AMAYA OS program on the computer.	OFF	Problem is probably software related. Reboot the computer. If the problem persists, reinstall the AMAYA OS software. If that does not fix the problem, contact Melco Technical Support.
