Light barriers for positioners
The light barriers in the robot system are used to stop the robot and positioner if
anyone enters the risk zone where moving parts are activated. The light barriers
can, where appropriate, be replaced by hatches, sliding doors or gates.
Pre-reset
A pre-reset button is located inside the service area. It is used in connection with
resetting the safety circuits for the light barriers. The pre-reset prevents
unintentional starting when the operator is inside the service area.
Action
Press the pre-reset button (this permits a pre-reset of the safety circuits for the light
barriers of 10 seconds). 1
Press and hold the start button (operator ready button) on the operator panel within
10 seconds.
2
Verify the safety functions
Before the robot system is put into operation, verify that the safety functions are
working as intended and that any remaining hazards identified in the risk
assessment are mitigated to an acceptable level.
