6.9 TROUBLESHOOTING THE SAFETY SYSTEM
Most problems that are likely to occur can be readily diagnosed using the messages on the Main screen,
the input status on the Main screen and the LED indicating lights on the Safety Relay in the Operators
Enclosure.
The most common problem you may encounter is that the Wood Runner system cannot be enabled or is
disabled by a random E-stop not caused by the operator. The random E-stop could be of an intermittent
nature and would be hard to diagnose without understanding the Safety system.
Main screen -
The text at the top of the screen will show the cause of an E-stop condition as long as the
condition still exists
Safety Relay -
Three LED’s are located on the Safety relay and are very useful for troubleshooting. The
Safety Relay is located in the Operators console. See the diagrams below for an explanation.
6.9a DIAGNOSING AN E-STOP PROBLEM THAT IS NOT INTERMITTENT
The E-stop cause is continually displayed at the top of the Main screen. Check the message at the top of
the screen to determine what device is causing the E-stop. Use the guide below to narrow down the
source of the problem.
