E-Stop Circuit Testing
The E-Stop circuit should be tested periodically to help ensure that the system
shuts down safely when the E-Stop button(s) is pressed.
Note
MTS recommends testing the E-Stop circuit at least once per month.
1. Remove any specimens from each station.
2. Apply power to the controller.
3. Start the HPU and each HSM associated with your test station(s).
4. Press the E-Stop button and ensure that the following global-interlock
actions occur:
•
Power is removed from each HPU.
•
Power is removed from each HSM.
•
If valve clamping is enabled, the actuator should move to the
predetermined position defined in software.
•
Any external I/O device that is monitoring the E-Stop circuit should
acknowledge the E-Stop state and take appropriate action.
5. Twist the switch clockwise to release it.
6. Repeat this procedure for each E-Stop button used with your controller.
