2.15 Safety Interlocks
Electromechanical interlocks prevent personnel from being exposed to high RF voltages, mechanical
hazards, and RF radiation hazards that are present while the FlexTRAK-OH Material Handler is in
operation. They function using a switch that trips when a door is opened. When the switch is tripped, the
FlexTRAK-OH Material Handler and reaction chamber cease movement.
WARNING! When these interlocks are activated, the electrical power remains ON.
There are total of eight (8) interlocks on FlexTRAK-OH Material Handler (Figure 2-11).
Figure 2-11 Safety Interlock Location
Once the interlock switch is triggered (sense guard door is open), it will cause the safety relay to cut off
machine servo motor power. See 8.6 System Block Diagram.
WARNING! Do not bypass the interlock switch that guards the access door in automated
operation mode.
Once the current process sequences have been stopped, no reset is possible until the guard door has been
closed. In order to resume operation, close the open guard door and press the RESET button.
