Bypass_Level_2	SoftShutdownDrum	ST unable to communicate or drive the bypass with the stepper motor drive. not a mechanical issue.	Reboot		PreheatBlocked	N
Exhaust_Blower	BeanCoolerShutdown	Exhaust Blower is not spinning at the expected speed	Inspect cleanliness of exhaust blower. ensure it is spinning MDU test. Replace as necessary. DO NOT UNPLUG THE BLOWER WHILE THE ROASTER IS ON. If replacement doesn't resolve, there may be an failed component on the Control or ST board	Cool_Beans_In_Drum	PreheatBlocked	N
Cool_Beans_In_Drum	None	Another alarm is curently on, causing the roaster to believe beans are trapped in the drum. This is induced by: shutdownDrum, BeanCoolerShutdown, CoolInDrumDuringCool	Inspect other alarms that induced this.		NonBlocking	N
Bean_Fr_Profile	ExpelBeans	After 3 minutes of roasting, the roaster is greater than 25F off of the Profile	Most likely a poorly designed customer profile. can also be caused by poor heating performance. Use a Bellwether profile Or inspect heating system		NonBlocking	N
Interlock_Blwr	ExpelBeans	The differential Pressure Switch is Open, meaning the roaster believes the blower is off	Inspect that the blower is running during ready state. this may be triggered from another alarm that turned off the blower.		PreheatBlocked	N
Interlock_Mn_Htr	ExpelBeans	The Main heater thermostat is has tripped. Blower and heaters are thus disengaged.	Inspect the continuity of the main heater interlock at the powerPCB. Ensure the main heater did not overheat per the logs		PreheatBlocked	Y
Interlock_Aux_Htr	ExpelBeans	The Aux heater thermostat is has tripped. Blower and heaters are thus disengaged.	Inspect the continuity of the aux heater interlock at the powerPCB. Ensure the aux heater did not overheat per the logs		PreheatBlocked	Y
Interlock_Drum	ExpelBeans	The Drum thermostat is has tripped. Blower and heaters are thus disengaged.	Inspect the continuity of the drum interlock at the powerPCB. Ensure the drum did not overheat per the logs		PreheatBlocked	Y
Bypass	ExpelBeans	The Bypass TC is reading significantly higher than the inlet TC, even when the bypass is commanded to close. i.e. the air is not going in the direction we expected.	Ensure the Inlet and Bypass TC's are functional. Inspect the motion of the Bypass. ensure it is moving 45 degrees between fully open and fully closed		PreheatBlocked	Y
Drum_Ag_Crit	ShutdownDrum	Drum Agitator Current Draw is at or over 1A, or it is drawing under 0.2A while it is running, or it is spinnining in the incorrect direction	Inspect the movement of the drum agitator (with the machine off). If there is noise or it is not smooth, inspect the chain drive or replace the bearing	Cool_Beans_In_Drum	PreheatRoast	Y

Preheat_Timeout	ShutdownDrum	The roaster was fully preheated but kept from entering roast for more than 30 minutes. Induced by a RoastBlocked alarm	Inspect other alarms that induced this.		PreheatBlocked	N
Preheat_Overheat	ShutdownDrum	Roaster Overheated during preheat	Inspect logs and confirm temperatures hitting the drum are reasonable		RoastBlocked	N
Drum_Empty	ExpelBeans	The Bean Front TC did not drop during the start of the roast, lending the roaster to believe the drum is unexpectedly empty.	Ensure the user did not forget to put beans in the hopper. Ensure the hopper flap is opening		NonBlocking	N
