The user selects 'maintenance' for an instrumentation division, the division's pressure channel is set to 'normal' mode, the pressure setpoint is set to a value v, the user simulates a pressure input to that division exceeding v, the division generates a pressure trip.
Normal Self-Test Behavior 1b - Trip on Environmental High Pressure Reading from that Pressure Sensor
The user selects 'maintenance' for an instrumentation division, the division's pressure channel is set to 'normal' mode, the pressure setpoint is set to a value v, the division reads a pressure sensor value division exceeding v, the division generates a pressure trip.
The user selects 'maintenance' for an instrumentation division, the division's temperature channel is set to 'normal' mode, the temperature setpoint is set to a value v, the user simulates a temperature input to that division exceeding v, the division generates a temperature trip.
Normal Self-Test Behavior 2a - Trip on Environmental High Temperature Reading from that Temperature Sensor
The user selects 'maintenance' for an instrumentation division, the division's temperature channel is set to 'normal' mode, the temperature setpoint is set to a value v, the division reads a temperature sensor value division exceeding v, the division generates a temperature trip.
The user selects 'maintenance' for an instrumentation division, the division's saturation channel is set to 'normal' mode, the saturation margin setpoint is set to a value v, the user simulates pressure and temperature inputs to that division such that the saturation margin is below v, the division generates a saturation margin trip.
The user selects 'maintenance' for an instrumentation division, the division's saturation channel is set to 'normal' mode, the saturation margin setpoint is set to a value v, the division reads pressure and temperature sensor values in that division such that the saturation margin is below v, the division generates a saturation margin trip.
The user selects 'maintenance' for each instrumentation division, the user configures a subset of channels to place in active trip output.
The user selects 'maintenance' for each instrumentation division, the user places enough channels in 'active trip' to actuate a mock device.
The user selects 'maintenance' for each instrumentation division, the user places enough channels in 'active trip' to actuate a hardware device.
The user manually actuates each device.
The user selects 'maintenance' mode for each instrumentation division in sequence.
The user exits 'maintenance' mode for each instrumentation division in sequence.
For each instrumentation division, the user provides a setpoint for temperature, then the user provides a setpoint for pressure, then the user provides a setpoint for saturation margin.
For each instrumentation division, the user puts each channel in 'normal' and then 'bypass' mode.
Normal Self-Test Behavior 10 - Configure Active Trip Output State of Each Instrument Channel in Sequence
For each instrumentation division, the user puts each channel in 'trip' and then 'normal' mode.
The user provides inputs for an instrumentation division, then the UI displays the updated pressure, temperature and saturation margin.
The user configures an instrumentation division in 'maintenance', selects a channel and places it in 'trip', the UI displays the trip state, the user places the channel in 'normal' mode, the UI displays the trip state.
The user configures an instrumentation division in 'maintenance', the user selects a channel and places it in bypass, the UI displays the bypass state, the user places the channel in normal mode, the UI displays the updated state.
The system starts, eventually the UI displays that self test has run.
The system selects two instrumentation divisions and a device, the system simulates inputs to the selected instrumentation divisions, the system checks that the correct actuation signal would be sent to the selected device.
Manually actuate Actuator 1, the actuator fails, an error is indicated.
Manually actuate Actuator 2, the actuator fails, an error is indicated.
Repeatedly manually actuate/unactuate an Actuator, the actuator fails, an error is indicated.
