System description Electronic monitoring system EMS 2

© 0702 Page 55 EMS 2 1 Foreword This system description provides an overview of the design and the operation of the electronic monitoring system (EMS 2). In addition, the functions which the EMS 2 contains, and the manner in which problems in the engine and in the EMS 2 can be detected, are explained.

© 0702 Page 57 EMS 2 Important notes 2 Important notes In the event of critical conditions, the EMS 2 may independently shut the engine off, either with or without prior warning depending on the configuration, or may merely provide a warning. The user must be informed of this and must be familiarised with limp-home mode. ! The following states can be recognised with the diagnostic lamp ! The illumination of the maintenance/service lamp demands that the engine be maintained by the DEUTZ Service department. Display State Indicates Diagnostic lamp illuminates for 2 s from ignition on. Lamp test System is ready for operation. Diagnostic lamp continuously illuminated. Warning regarding exceeded limit values and system faults. A reduction in power is only possible in combination with an engine governor, e.g. EMR and MVS. The reduction in power can be temporarily bridged with the limp-home mode button. (Depression of the button is confirmed with slow flashing, see *). After the engine has been shut-off, fault code enquiry is possible (see **). Diagnostic lamp flashes rapidly (approx. 1 Hz). Emergency engine shut-off if shut-off limits are exceeded or not achieved. Attention: In a few seconds, the engine will be automatically shut-off for the purpose of protection. The reduction in power can be temporarily bridged with the limp-home mode button. (Depression of the button is confirmed with slow flashing, see *). After the engine has been shut-off, fault code enquiry is possible (see **). * Diagnostic lamp flashes slowly (approx. 0.5 Hz). The limp-home mode button has been actuated in order to bridge the reduction in power or engine shut-off. Bridging is stored in the control unit. Attention: Following actuation of the limp-home mode button, the engine continues to run without protection for a short time, and may become damaged! For this reason, only actuate the button in the event of an emergency (e.g. if life is otherwise placed at risk)! ** Fault code enquiry The diagnostic lamp serves to display a fault code (a sequence of short and long flashing impulses). In the event of engine standstill, an enquiry regarding the fault code may be made with the limp-home mode button/ diagnostic button, see Chapter 8.4.

It can be used on its own and also in combination with the MVS (solenoid valve system) or the EMR (electronic engine governor). The EMS 2 provides functions for engine protection, for indicating maintenance requirements and for diagnostic purposes. With the aid of the data recorder function, an overview of the manner of operation, capacity utilisation and possible causes of engine failure may be obtained. In addition, data exchange with other electronic control units (e.g. EMR, MVS) is possible via the CAN interface. 3.2 System overview 3.2.1 EMS 2 alone EMS Control unit Vehicle-side/ System-side facility Engine-side facility Energy supply Glow-start switch Multi-functional display Configurable outputs (e.g. indicator lamps) Maintenance/service Diagnostic lamp Flame system solenoid valve Flame system temperature sensor Engine speed Oil level switch Alternator Starter Coolant temperature sensor Engine shut-off lifting magnet Oil pressure sensor Diagnostic button/ limp-home button Diagnostic interfaces • S, L line (ISO 9141) • CAN bus (SAE J1939) • SAE J1708 / J1587 Air filter differential pressure sensor Coolant level switch © 0702

© 0702 Page 61 EMS 2 System functions 4 System functions 1 4.1 Introduction The EMS 2 serves to electronically monitor the engine. Its functions include: Engine protection functions ● Warning the operator if limit values are exceeded or not achieved. ● Reduction in engine power. ● Emergency engine shut-off if operating data exceed or do not achieve the shut-off limits. Indication of maintenance requirements in order to remind the operator and to reduce the consumption of operating media. The maintenance intervals can be obtained from the DEUTZ engine operating instructions, Chapter 5.1. ● in the event of excessive air filter differential pressure. ● if the number of operating hours leads to the achievement of the next maintenance requirements. ● if the load population reaches a maintenance limit. ● if calculation of the engine operating statuses (temperatures, speed, etc.) results in the oil change limit's being exceeded. Data exchange with other systems via the CAN interface, e.g. with the solenoid valve system (MVS): ● Transmission of the output reduction signal if limit values are exceeded. ● Engine shut-off via the CAN interface sets, e.g. the fuel injection quantity to zero. ● The integration of measurement data and fault messages via the CAN interface extends the input signals of the EMS 2 for executing engine protection functions and system diagnosis (see above). ● Transfer of the EMS 2 measurement data to other systems. Diagnosis of the entire system ● System self-diagnosis, i.e. of the control unit, the sensors and the actuators. ● Display of engine operating data and self-diagnosis data on a PC (ISO9141 / RS232). ● Forwarding of the engine operating data to the SAE-J1708/1587 interface for diagnostic and display systems. ● Actuation of a telltale and output of a flashing code for fault identification. Data recorder Determination of the manner of operation, capacity utilisation and causes of engine failure. ● Recording the most important measurement variable signals. ● Determination of the load population. ● Storage of exceeded maintenance intervals. ● Documentation of hours of engine operation. Engine operation display ● Output of a signal (telltale or relay) as soon as the speed exceeds 400 rpm. 1) Not all functions are available in all applications.

© 0702 EMS 2 System functions 4.2 Engine protection functions 4.2.1 General The following table contains an overview of the measurement variables which can be monitored, together with the relevant, possible engine protection functions. ● If the measurement variable lies within the warning range, the diagnostic lamp is continuously illuminated. As a result of a command via the CAN interface to the EMR or MVS, the power is reduced. If the measurement variable exceeds/does not achieve the recovery threshold, the lamp is extinguished again. ● A reduction in power is only possible in combination with EMR and MVS. ● If the measurement lies within the shut-off range, emergency engine shut-off is carried out following the expiry of a waiting period. The diagnostic lamp flashes rapidly (frequency approx. 1 Hz). Shut-off is effected either - via a shut-off solenoid or - via the CAN interface on other electronic control units (EMR, MVS) ● Limit values which are exceeded or not achieved are documented in the fault memory . ● The fault message is output if the diagnostic button is actuated during engine standstill - as a flashing code via the diagnostic lamp. - with a notebook connected via the ISO9141 interface with the SERDIA diagnostic programme. - via the ISO J1708/1587 interface according to standard. ● Starting prevention can be recognised via the rapid flashing of the diagnostic lamp (1Hz) in the event of engine standstill. If the EMS 2 has shut the engine off on the basis of the engine monitoring functions, restarting is prevented. The same applies if monitoring is carried out during standstill, and engine starting is blocked due e.g. a low coolant level. ● The engine can be restarted by switching the ignition off/on (terminal 15). ● Outputs may also be used to initialise lamps or relays if limit values are exceeded or not achieved, see Chapter entitled Outputs 5.2. Monitorable measurement variable Possible engine protection function 1 1 The configuration is programmed in the factory.
