to Control Unit Time Actuating Force Control Unit Safety Outputs Power to Control Unit 35 ms Response Time Time Rockwell Automation Publication 95302194/EO:0240 Issue No: 8 25 440F MatGuard™ Mat Manager User Manual Section 5 - Installation Design will remain “OFF” until reset after power up and may require master/slave reset circuits in complex systems where other power up interlocks (start interlocks) are present. Auto Reset Mode In auto reset mode the output “ON” signal is achieved solely by removal of the actuating force. For both modes, the safety contacts will always be “OFF” (open) after the mat is actuated. When used in the auto reset mode, the machine’s control system will need a separate reset function to prevent machine start up when stepping off the mat or after a temporary power supply failure or dip. Selecting the Power Supply The Allen-Bradley Guardmaster MatGuard Mat Manager control units offer two possibilities for power supply. Check that the power supply parameters conform to the requirements of Allen-Bradley Guardmaster system as given in the specification. Where a 24V DC supply is used it must be isolated from the mains supply in accordance with international electrical safety practice (IEC 364- 4-41). One pole should be earthed (negative to be earthed for DC supplies). Auxiliary Output This is a non-safety output provided as a status output. It is particularly useful in systems using PLC functional machine control in combination with hard wired safety circuits as a status import to the PLC. Other uses include diagnostics in protection schemes and/ or driving status lamps or alarms. The safety function must not depend on this output. Arc Suppression Arc suppression networks or devices are recommended for all inductive loads. For safety circuits, suppressors should be fitted across the load and never across the contacts. The type and ratings of the suppressors will be determined by the supply and load characteristics. Note that suppressors can increase response time, particularly suppressor diodes across DC coils, and should be in place when measuring response times. 5.8 Final Sensor Mat Layout Having considered these factors, the sensor mat layout can now be checked and finalized. Consider whether the machine response time has changed from the initial calculations. Whenever possible, mats should be arranged with the wires at the outside edge of the detection zone. This simplifies installation and replacement if required and all wiring is protected by the perimeter trim. 5.9 Wiring All Allen-Bradley Guardmaster wiring must be protected from mechanical damage and suitably sealed for the operating environment. Waterproof butt connectors are supplied for mat to mat connections and are protected by the edge trim. Where wire runs are required across the floor,
