The circuit conditions are as follows: supply power is ON; no presence on the sensor mats, the normally open safety outputs are closed and the loads are de-energized. The control unit is configured for automatic/manual reset. Press and release the start button to energize the loads. Stepping on any of the mats will cause the safety outputs to open and remove power to the loads. After stepping off the mat, the start button must be pressed and released to re-energize the loads. Figure 21 Figure 22 shows an example connection diagram for the 440F-C28026. The circuit conditions are as follows: supply power is ON; no presence on the sensor mats, the normally open safety outputs are open and the loads are de-energized. The control unit is configured for monitored manual reset. Press and release the reset button to energize the loads. Stepping on any of the mats will cause the safety outputs to open and remove power to the loads. After stepping off the mat, the reset button must be pressed and released to re-energize the loads. + 24V DC DC Ground PE Ground Fuse Start K1 Aux K2 Aux Stop 1 23 4 2 5 6 7 8 1 6 440F-C28025 Mat Manager Control Unit K1 K1 K2 K2 3 758 Up to 8 Sensor Mats Motor L1 L2 L3 Reset M A 440F MatGuard™ Mat Manager User Manual Section 5 - Installation Design 24 Rockwell Automation Publication 95302194/EO:0240 Issue No: 8) Figure 22 After completion of the design of the safety related control system ensure that the response time assumed at 5.4.1 remains valid. If the value changes, it will be necessary to repeat the safety distance calculations. Next consider the options for reset. The consequences of the reset scheme selected should be carefully considered for hazards caused by unexpected start up etc., both under normal conditions and under fault conditions. Timing diagrams are given in Figure 23 for both modes of the Allen-Bradley Guardmaster system. Figure 23 Two Reset operating modes are configurable via selection switch inside the Control Unit: Manual Reset and Auto Reset. Manual Reset Mode In manual reset mode the output “ON” signal can only be restored after the actuating force has been removed and after a reset. The manual reset is achieved by pushing and releasing a remotely mounted momentary reset button or by voltage free contacts within the machine safety related control system. At power-on or following the loss and subsequent restoration of power, the outputs will be “OFF” until a reset signal is received even if the mat is not actuated.
