APM 01085A J. Nilsson New safety system. Why? Some facts. Increased flexibility User friendly, status information on the teach pendant Simplified local engineering Required for the new positioners and the next generation of robot controller Easier assembly and less wiring The new safety system is reqiured for the new positioner program. It is not backward compatible with the present system. The B* and D* positioners still use the current safety system. New Safety System * New version ready Q3 2002

APM 01085A J. Nilsson New Safety System Designed for the new station interchange units. Software supervision performed by the robot control system. Hardware supervision (position switch) performed by the safety interface. Interchange supervision

APM 01085A J. Nilsson New Safety System Designed for the 4-station index positioner.

APM 01085A J. Nilsson New Safety System Tooling interlock Prevent automatic clamping of the work piece while the operator is within the load area. Signals from the light beams / roll door* and station indication switches* are distributed to the tooling control system. Valves for clamping devices on tooling Tooling control system Safety interface SIB5 * *

APM 01085A J. Nilsson New Safety System Status information. Program Stop Service door open Please close the door and reset the system. Information from the safety system in plain language. Ready Q

APM 01085A J. Nilsson New Safety System Prepared for roll door and hatch. Roll door open Roll door closed Safety interface SIB5 A timer in the safety interface resets the safety system from the moment the operator has pressed the operator ready until the door/hatch is closed. The time is set on the teach pendant. Roll door control system

APM 01085A J. Nilsson New Safety System Prepared for signals from different brands of light beams. Configuration of output from the light beam Relay 2 x NO Relay 1 x NO 1 x NC Transistor 1 x PNP 1 x NPN Transistor 1 x PNP Transistor 1 x PNP 1 x PNP INV Activated Not activated Activated Not activated Activated Not activated PNP +24V NPN 0V PNP ---- NPN ---- PNP +24V PNP ---- PNP +24V PNP INV ---- PNP --- PNP INV +24V Activated = Light beam is broken
