• Engine command via protocol J1939 (CIU mode):
- Engine start-up and stop by J1939 frame.
- Override operational mode (forced running).
- Engines:
TEDOM: replacement HMI TEDOM.
SCANIA: replacement CiU.
IVECO TIER3: is compatible with the TIER2 communication
frame.
ALL: Start-up and stop via CAN frame.
The engine condition transmitted by the CIU through the J1939 communication
bus is displayed through the INPUT/OUTPUT screen if it is detected that the
J1939 extension is installed or option J1939.
Also, 2 new screens are incorporated with option 9 on the MENU screen:
1. Display screen of engine errors: on this screen the list of previous active and
passive errors detected by the engine regulation is displayed. On the initial
screen a complete list is displayed of the errors detected. When accessing using
the accept key, for each error the following is displayed:
• Error code.
• Hours engine running when the error occurred.
• If it is an active or passive error.
• Flashing code associated to the error.
Through password level 3, it is possible to clear the list of passive errors stored
in the electronic regulation of the engine.
2. Only expansion CCJ1939: Display screen for control unit starts via the J1939
extension in autonomous mode. The J1939 extension allows an autonomous
operating mode through which it is possible to start and stop the engine
independently of the control unit. These starts are recorded in the J1939
extension together with the engine running hours of the electronic regulation.
8.2 TELESIGNAL
The CEM7 control unit allows connection of a Telesignal device. The Telesignal
device has 12 relay outputs (4 with NO and NC contact, 8 with NO contact).
The outputs of the Telesignal device can be programmed to be activated
depending on:
• Any active alarm or pending notication from the control unit.
• Any active input of the control unit.
• Any active output of the control unit.
• Control unit mode (Automatic or manual).
Each output of the Telesignal device is activated when at least one of the
activation conditions have been programmed.
8.3 CCJ1939/CEM7 WITH J1939 OPTION
Both the J1939 option and the CEM7 control unit with the expansion CCJ1939
can monitor the following engine operating parameters depending on the
manufacturer and model:
• Measurements of pressure, temperature.
• Engine alarms.
• Engine error codes.
• Start and stop operations.
• Fine adjustment of speed via parameters.
• Only expansion CCJ1939: speed adjustment by analogue input from
0-10V (synchronization).
• Only control unit with J1939 option with expansion CCRS MODBUS:
External engine speed control via MODBUS.
