Table 7-11 Troubleshooting a Keyboard Failure

Step

What to do

How to do it

1Make sure the keyboard is connected properly to the MCU/output and power/input boards.

Withdraw the chassis from the case and visually inspect the connection.

2Controller Keyboard or specific keys may be LOCKED OUT via the security code.

3Run the keyboard test.

Use your four-digit security code number to change the lockout level. Refer to Section 3 – Configuration.

Press the [SET UP] key and hold in, then press the [FUNCTION] key at the same time. The controller will run a display test. Then you will see:

Upper Display

KEYS

Lower Display

TRY ALL

		Press each key. If it works, the key
		name will appear in the lower display.
4	Replace the display/keyboard if any	Refer to “Parts Replacement
	keys do not function.	Procedures” in this section.
