Annunciator Miscellaneous Settings

From EMIT Controls

There are some settings for the Brain that do not fit in another section so are put under Setup -> Brain -> Misc. Settings. The settings and their purpose are shown below

Setting Description
Scrubber Debounce (s) This setting gives a special debounce time for digital inputs that are used for scrubber levels. For example, if set to 3 seconds then the input will have to be faulted for 3 full seconds before shutting down. This can be used if a scrubber switch tends to flutter.
Start Gas Cutoff after Engine Run (s) This gives the amount of time after the engine rpm goes high before the start gas block valve closes
Light tower output inverted If set to YES, then the light tower segments will flip their logic. This can be used if old boards or light towers are showing up backwards (e.g. red while running)
Suction low debounce (s) This gives a special debounce time to the analog input used for suction pressure. The input has to be below the alarm limit for this number of seconds before faulting out.
Max Valve Change Time (s) If using on/off valves with valve feedback, after changing the output direction the Brain will check that the input changes to the expected end stop as well. This is the amount of time a valve can be out of sync before an alarm is generated.
Invert DC SHDN Pin The DC SD pin (Pin 9 of the annunciator) is normally grounded to stop and ungrounded to run. If this setting is set to YES, then the logic will be flipped so that the pin will be grounded to run.
Analog vibration debounce (s) This setting gives a special debounce for vibration sensors on analog inputs. The input will have to be faulted for this many seconds in a row before generating an alarm.
Fuel gas on for lube Normally the fuel gas valve doesn't come on until after pre-lube completes. If the fuel gas has to come on earlier, then this setting can be changed to YES.
Require idle at startup If set to YES, then the panel won't start unless the speed switch is in the Idle position. After starting the switch can be changed.
Continue pre lube through crank If set to YES, then the lube output will stay energized until the engine is actually detected to be turning.
Crank Terminate RPM This gives the RPM that the panel will consider past cranking and in running. This might be adjusted on low speed units where the run signal is not incrementing. This is separate from the RPM threshold that causes the panel to go from "Waiting for ECU to start" to "Running", which is under Output Setup -> ECU Selection.
Monitor comp. oil during drank If set to YES, the brain will fault if the engine starts turning and the compressor oil pressure doesn't start building up within a few seconds.
