The J1939 Messages can be browsed by using the UP and DOWN arrows, and the list exited at any time by utilizing the return to previous menu key . Depending on the application the J1939 parameter list provides a host of information from the engine control unit (ECU), this can include, oil temperatures, pressures, fuel rate and various other engine parameters.

Scania Specific Fault Codes

For Generating sets utilising the Scania electronic engine the user can request blinkcodes (for engine diagnostics) and reset them. To request a blinkcode while viewing the above screen press the ‘Blink code req’ - soft key, repeated pressing will scroll through all logged & active fault codes. While viewing blinkcodes they can be cleared by pressing the ‘Reset Blinkcode’ soft key causing the code to be reset as long as the fault is not active.

Appendix 1 Possible Alarms

This appendix lists all the possible alarms displayed in the JCB Digital Control Panel ‘Alarm List’ screen

Overspeed 1

Overspeed 1 Indicates that the engine has experienced / is currently in an overspeed condition (above the first overspeed set limit).

Over Speed 2

Overspeed 2 Indicates that the engine has overspeed past the second overspeed limit value, this error will cause generating set shutdown.

Underspeed 1

Underspeed 1 indicates that the engine has experienced an underspeed condition (fallen below speed limit 1).

Underspeed 2

Underspeed 2 indicates that the engine speed has fallen below the second threshold point, and will cause shutdown of the generating set.

Gen. Underfreq.1

Under frequency Indicates that the generated frequency has gone below the minimum allowed value typically 90% of rated frequency. Can be a result of overloading the generating set.

Gen. Overfreq.1

Over frequency indicates that the generated frequency has gone beyond the maximum allowed value typically 110% of rated frequency.

Oil.Temp.1

Oil Temperature Level 1 warning Indicates that engine oil temperature of the generating set has reached an abnormally high value.

Oil.Temp.2

Indicates that the Oil Temperature has increased beyond threshold level 2 and will cause generating set shutdown.

Water.Temp.1

Water Temperature Level 1 Warning indicates that the engine coolant temperature has reached an abnormally high value.

Water.Temp.2

Water Temperature Level 2 warning indicates that the coolant temperature has increased beyond the second limit point, and will cause a generating set shutdown.

Water Temp Sw

Water Temperature Switch indicates that the coolant temperature has been/is abnormally high.

Stop Pressed

Stop Pressed / Emergency Stop Indicates that the machine has been manually shutdown by use of the STOP switch on the panel, or other external emergency stop buttons (warning must be acknowledged before restart can take place).

Unintended Stop

Unintended Stop indicates that the JCB Digital Control Panel is expecting to see generated frequency and voltage but none is present. This can happen for example if the engine runs out of fuel and stops without Control panel commanding it to stop.

Batt.Undervolt.1

Battery Undervoltage alerts the user to the fact that the generating set-starting battery voltage is below the expected level. This can indicate that the charging alternator / static battery charger are not functioning correctly /have been disconnected. Could also be activated if the system is 24V but has been incorrectly connected to a 12V battery.

Batt.Undervolt.2

Indicates that the battery voltage has fallen below a second threshold point

Batt.Overvolt.1

Battery Over Voltage alerts the user to the fact that the generating set-starting battery voltage is above that expected by the Control panel. This can point towards a fault in the static battery charger or charging alternator. Could also indicate that a 12V system has been incorrectly connected to a 24V battery.

Batt.Overvolt.2

Indicates that the battery voltage has increased beyond the second threshold point.

CAN-Fault J1939

CAN Fault J1939 Indicates that connection to the Engine CAN Bus has failed and no data can be transmitted over the bus. This could be cause by incorrect, faulty or loose CAN wiring.

Shutdown Malfct

Shutdown Malfunction indicates that the engine has failed to shutdown when commanded. When stop is pressed the JCB Digital Control Panel intelligently monitors the engine to see if the STOP command has been fulfilled. Most common cause would be incorrect / faulty wiring to the fuel solenoid.

Mainten. Days Exceeded

Maintenance Days Exceeded, the generating set has exceeded the configured number of days since the last maintenance period.

Mainten. Hours Exceeded

Maintenance Hours Exceeded, the generating set run time has exceeded the configured number of days since the last maintenance period

GCB Fail to Close

Depending on the system configuration the JCB Digital Control Panel will continue to try and close the GCB while the conditions are fulfilled.

GCB Fail to Open

The JCB Digital Control Panel is still seeing the GCB closed signal after it has commanded it to open, and after the configured period of time.

MCB Fail to Close

The JCB Digital Control Panel has attempted to close the Main circuit breaker the configured number of times, depending on the system configuration the Control panel will continue to attempt closing of the MCB as long as the conditions are right.

MCB Fail to Open

The JCB Digital Control Panel is still receiving the MCB closed signal after it has commanded it open and the monitoring time has expired.

Emergency Stop

Either the Canopy (if fitted) or the panel mounted emergency stop switch has been pressed. In order to reset the ESTOP button must be released and the alarm acknowledged before restarting is possible.

Appendix 2 Status Messages

This appendix contains the list of status messages that the JCB control panel can flag up to indicate various conditions.

Preglow

Indicates that the Diesel engine is heating in preparation for starting.

Start

Indicates that the engine start sequence is active, appears after any prerun auxiliary operation (preglow). JCB Digital Control Panel activates the start relay and/or CAN message is sent to engine to demand starting.

Start Pause

If the engine does not start after cranking, ‘Start Pause’ is displayed during which time the controller will pause for a period before attempting another start. If the engine fails to start after three attempts then the routine stops and the Control panel displays alarm ‘Fail to Start.

Crank Protect

This message is displayed if the engine is running or has just been stopped and the START button is pressed. The JCB Digital Control Panel protects the starter by stopping its operation if the engine is rotating (can be stopped and still turning or actually running).

Cool Down

The JCB Digital Control Panel allows the engine to run for a predetermined period after a stop signal has been received, to promote engine cool down before it mechanically stops. Cool down is not entered if emergency stop is pressed or if STOP soft key is pressed twice (immediate stop requested).

Stop Engine

Engine will be stopped, a restart will not be allowed (crank protect) until controller observes the absence of speed and frequency for a period of time.

GCB Dead Bus Close

The Generator Circuit Breaker is closed unto a de-energised busbar. This is activated by either the absence of a MCB or by reply ‘MCB is open’. During commission ensure that no other sources are energizing the busbar, if this information is unknown check busbar status by another means.

MCB Dead Bus Close

The Mains Circuit Breaker is closed unto a de-energised busbar, actuated by the JCB Digital Control Panel receiving GCB is open signal. During commissioning ensure that the busbar is de-energised, if unknown check busbar status using another means.

Emergency Run

The JCB Digital Control Panel detects that a mains fault has occurred and starts the engine after a pre determined delay period. The MCB is opened and GCB closed, the generating set accepts the load. When mains power returns, The JCB control panel goes into ‘Mains settling’ mode

Mains Settling

In Emergency Run when the JCB Digital Control Panel determines that the Mains power has returned, it monitors the Mains for a pre determined time to ensure that the mains is stable, before opening the GCB, closing the MCB and passing the load back to the mains.
