Safety checks
Before beginning the test in the chair system, certain safety tests must be done as described below.
Safety checks for for Orion Auto-Traverse and Orion Comprehensive
- Watchdog safety: Make sure the E-stop has been disengaged. The E-stop will remain off until one
enters the VisualEyes™ software and clicks on Begin Testing or goes into
System Default Settings >
Rotational Chair
and selects “Orion A/C”. Exiting VisualEyes™ will turn off the E-stop light after a
few seconds. This ensures the Watchdog safety is working.
- Booth door safety: Click Begin testing with the booth door open. You should receive a message
alerting that the booth door needs to be closed to continue testing. Close the booth door and go to a
rotational chair test. You will get a safety checklist. The list needs to be checked before test can
begin.
