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
- 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 I/O 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.
(Note: With the option NiCad batteries, no boost is used and there is no NC dry contact. The "Charger Fail" alarm is
detected when the battery voltage goes under the float voltage and no current is detected between the charger and
the battery.)
- Loss of Continuity 1-2: Activates if the engine start contactors are disconnected from the controller.
- Water Res. Low: Activates if the “Water Reservoir Low” contact input is triggered or if the analog readout of the
water reservoir is enabled and is lower than the water reservoir low set point in the “Water Level” sensor page.
- Water Res. Empty: Activates if an external contact triggers the optional “Water Reservoir Empty” input.
- Main Relief Valve Open: Activates if an external contact triggers the optional “Main Relief Valve Open” input.
- Fuel Tank Leak: Activates if the “Fuel Tank Leak” contact input is triggered.
- Low Fuel Level: Activates if the “Low Fuel Level” contact input is triggered or if the analog readout of the fuel level
is enabled and goes lower than the low fuel level set point in the “Fuel Level” sensor page.
- High Fuel Level: Activates if the “High Fuel Level” contact input is triggered or if the analog readout of the fuel
level is enabled and goes higher than the high fuel level set point in the “Fuel Level” sensor page.
- Engine Fail When Running: Activates if the “Engine is running” signal is lost while the engine is running. The
engine will try to start the cranking sequence once again if the starting causes are not back to normal.
- Engine Fail to Start: Activates if the engine fail to start after the complete 6 attempts crank sequence. The engine
will turn red.
- Engine High Temperature: Activates if the specific “High Temp” input is triggered on the engine connector strip
and the engine is running. This alarm will stop the engine only if triggered during a manual run test.
- Engine Low Temperature: Activates if the specific “Low Temp” input (15) is triggered on the engine connector
strip.
- Engine Low Oil Pressure: Activates if the specific “Low Oil Pressure” input is triggered on the engine connector
strip and the engine is running. This alarm will stop the engine only if triggered during a manual run test.
- Engine Overspeed*: Activates if the speed read is higher than the set Overspeed value and the engine is running.
This alarm will stop the engine only if triggered during a manual run test.
