Font Paragraph Here is a portion of a design document showing some requirements for High Pressure Coolant (HPC). 1.0 Inputs 1.1 Requirements REQ 4.2.1-5: A parameter must be available to enable or disable HPC REQ 4.2-21: When the parameter Enable HPC feature is disabled, the HPC coolant must not be turned on or off. A message "Feature Disabled" must be generated if button pressed or commanded by M code. REQ 4.2-20: HPC coolant must not be turned on or off, when coolant override setting (setting 32) is set to off Message "Function lock is displayed. REQ 7.8.84: There must be a key to turn on and off high pressure coolant. REQ 9.13.61-1: There must be an M-code M88 to turn on High Pressure Coolant REQ 9.13.11-1: There must be an M-code M89 te turn off Through Spindle Coolant. REQ 4.2-22: HPC must only be turned on or off via M Code or COOLNT button in MDI, MEM and only with COOLNT button in JOG mode otherwise a message "Wrong Mode" is generated REQ 4.2-9: A Coolant Pressure Monitor shall monitor the coolant line pressure while the high pressure coolant pump is turned on. REQ 4.2-10: During Coolant Monitoring when the coolant pressure drops below a parameter (P1295) and continuously passes the amount of high pressure coolant delay time (P2079) and the high pressure coolant pump is turned on, Alarm 151 HPC LOW PRESSURE will be displayed. 1.2 Inputs SHIFT COOLNT key M88/M89 MCodes Setting 32 -Coolant Override Parameter 209 Bit 24 - Enable or Disable HPC (High Pressure Coolant) Parameter 1295 HPC Sensor Pressure Threshold Low (PSI) Parameter 2079 HPC LOW Pressure Fault Time Pressure sensor input 1.3 Outputs High Pressure Coolant pump outputs Alarm 151- HPC LOW PRESSURE Function lock Feature Disabled, or Wrong Mode messages TEST CASES (list several test cases for the requirements above. 2 were started for you) 1. Verify when HPC is disabled via setting 32, a message "Function lock" is generated if button pressed or commanded by M code. 2. Verify when HPC is enabled, in MDI and MEM modes HPC can be turned on or off via M Code or COOLNT button. 3. 4. 5. 2.0 Traceability matrix (show a matrix for your tests above)
