Tornatech GFD User Manual

25
- Battery Failure 1-2
- DC Failure
- Over Pressure
Pump Room Trouble: A common alarm activated when the following events occur:
- Fuel Tank Leak
- Low Fuel Level
- High Fuel Level
- AC Failure
- Low Pump Room Temperature
- Low Suction Pressure
- Water Reservoir Low
- Water Reservoir Empty
CTRL Trouble: Important: this relay is normally energized when controller is in normal condition. The relay is
de-energized when controller trouble is detected (fail safe). The controller trouble common alarm is active when one
or more of these conditions are active :
- Charger Failure 1-2
- DC failure
- Default Solenoid Valve
- Cut-In not reached during test
- AC Failure: Monitors the AC power and activates on a failure.
- Battery 1-2 Fail: Monitors the status of battery 1 and activates on a failure. This occurs when the battery is
disconnected, is the wrong type or is unable to be recharged. When disconnecting a battery, there will be a delay
before the alarm is activated. The boost signal will be active a minute later, or more if a ghost current is detected. If
there is no response from the battery, it will execute a second test 30 seconds later, and then activate the battery
failure alarm.
- Charger 1-2 Fail: Monitors the state of battery charger 1 and activates on a failure. This occurs when the battery
charger has a defect, is not properly powered, or is unable to provide the needed current. It will also change to
Boost Fault mode if during a boost test, the voltage does not rise. A NC dry contact is also connected from the
charger to the IO Board. If this contact opens for 1 minute, the alarm will be activated. Chargers readings are not
updated during cranking and/or running, due to reading instability under load. As soon as the engine returns to an
idle state, all readings and failure analysis are reactivated.
- Service Required: Activates when service is due for the controller. This occurs when the date set in the service
page has passed, or if no service has ever been done.
- Weak Battery 1-2: Activates if the battery voltage falls below the weak battery set point in the factory settings
page.
- Loss of Continuity 1-2: Activates if the engine start contactors are disconnected from the controller.
- Low Pump Room Temp: Activates if the optional programmable input “Low Pump Room Temp” is activated by an
external signal.
- Low Spare Temperature: Activates if the analog readout of the spare temperature input is Enabled and is lower
than the low spare temperature set point in the “Spare temperature” sensor page.
- WT CI Not Reached: Activates if the Cut-In is not reached during a manual run test or a weekly test timer. At the
end of the 255s timer, if the Cut-In is not reached, the test may still be successful at starting the engine if the
pressure has dropped by at least 5 PSI.
- WT Check WT Solenoid: Activates if the pressure does not drop a minimum of 5 PSI during the manual run test or
the weekly test. Indicates a failure with the Test Solenoid Valve.
