This alarm indicates that the guards were not detected either when the Start button was pressed or while the batch was in process. Reset the alarm and then check that the guards are in position and locked in place before starting again.

With the guards in place, press F3 to open IO screen and check DI4 for illumination, if off then the safety relay has not reset. Inspect that the safety sensors are clean and nothing is blocking them. If this does not resolve the alarm then place the guards in position, and then turn the machine off for 15 seconds before powering on. This should clear any errors inside the safety sensors.

It is possible for this fault to occur on start up if power was lost to the machine while it was in cycle. The alarm will appear on the screen after attempting to start a cycle. Simply reset the alarm and continue operation.

If this alarm is occurring during a cycle with all the guards pinned in place, then the safety sensors may need to be repositioned.
