Chapter 3 Troubleshooting problems
Step 1: Check configurations
Many times what appears to be a Dyno controller fault is actually an easy-to-fix
configuration problem. Check settings in the K2 Summit Production Client
Configuration Manager and the Dyno Replay application Config tab and verify that
the system is configured as you expect.
Step 2: Check connections and external equipment
Loose or improperly connected cables are the most likely source of problems for the
system. A quick check of all the cable connections can easily solve these problems.
Refer to the troubleshooting topic
“Checking external equipment” on page 45 if you
suspect a failure in a connected device.
Step 3: Identify problems using the startup
sequence
The startup sequence is a primary tool for identifying a Dyno controller fault. As the
different levels of the Dyno controller system become operational in the startup
process, the primary components of the system are checked. You can identify most
problems by evaluating the messages and other indicators that occur during the startup
sequence.
To identify problems using the startup sequence, do the following:
1. Connect mouse, keyboard, and monitor. You must observe the VGA screen and be
able to interact with the system via keyboard and mouse to fully identify problems.
2. Restart the Dyno controller. If you have problems, refer to “Shutdown/restart
problems” on page 44 .
3. Once the startup sequence begins, observe the progression of behaviors. If you
observe error behaviors, refer to the indicated troubleshooting topics to identify
problems.
NOTE: You can press the Pause/Break key on the keyboard to keep BIOS text on
the screen for longer viewing.
Step 4: Run hardware diagnostics
With the Dyno controller diagnostics, you can check if the hardware is operating
normally as to whether:
• the buttons are illuminated in corresponding colors
• the button brightness can be changed
• the T-Bar position information is correct
• the hardware responds to the JOG operations properly
• the touch panel detects correct positions
• the touch panel brightness can be changed
