The Model 701HC is a Manual Engine Control Module designed to control the engine via key switch and push buttons on the front panel. The module is used to start and stop the engineand indicate fault conditions,automatically shutting down the engine and indicating the engine failure by LED, giving true, first up fault annunciation. An integralanti-tamper LCD hours run counter is also provided.

Operation of the module:

1. Select manual run ()
   
2. Press pre-heat button (v) for required length of time
   
3. Press START (I) to crank engine

In the ‘O’ position the DC supply is removed from the module and the run output is de-energised.

The module is powered up whenis selected. Operation of the pre-heat button is only possible when in this position.

An LED tell-tale indicates preheat operation. Once the required pre-heat duration has elapsed, the pre-heat button should be released.

Onceis selected and the Start button is pressed and maintained, the engine fuel system is energised. The ‘Crank’ output is then energised and the starter motor operated, disengaging automatically when the engine fires or when the ‘Start’ button is released. The protection hold-off timer is then initiated.

Operation of any of the following alarms (which are close on fault) will cause the run output to deenergise:

• Low Oil Pressure
  
• High Engine Temperature
  
• Auxiliary Shutdown
  
• Overspeed

This will remove the fuel supply from the engine and bring it to rest.

Each alarm has its own LED indicator and once activated no further alarm conditions will be accepted. The alarm output and relevant LED will remain active until the unit is reset by turning the switch to the ‘O’ position.

Overspeed Protection

Overspeed protection is derived from the generator Hz output. The overfrequency circuit monitors the generator Hz output and will shut down the engine immediately if a pre-set frequency level is exceeded. This trip level is selected by a switch for either 50Hz or 60Hz nominal operation (57Hz and 68Hz trip respectively).

During engine cranking and for a short time afterwards the protection hold-off timer (10 seconds) is active and the relevant alarm inputs are inhibited. This enables the engine to start and achieve normal running conditions. Once the timer has expired the inputs are enabled providing normal protection from the module.

Charge Failure warning is also provided by monitoring the WL terminal on the charge alternator.

LCD Hours counter is incremented whenever the engine is running. The elapsed hours are displayed in all modes except the ‘O’ mode.

The 703 is an engine auto start and protection module. It utilises advanced surface mount construction techniques to provide a compact, yet highly specified module.

Operation is via three push buttons mounted on the front panel with STOP, MANUAL and AUTO positions.

Stop mode - This is used to stop the engine when it is running and to cancel ‘Auto’ mode. It is also used to reset any Shutdown Alarm conditions.

Manual mode - This mode is used to manually start and run the engine, which can be stopped by pressing the Stop button.

Auto mode - This selects the automatic mode of operation, in which the module will await the remote start signal. Once received, the module will initiate its preconfigured Start Sequence, observing the start delay timer before starting the engine. When the remote start signal is removed, the module will initiate its preconfigured Stopping Sequence.

The module monitors the engine and provides the following functions:

• Automatic Start with 3 attempts and Automatic Crank Disconnect - with adjustable Start and Stop Timers and Fail to Start indication.
• Configurable Pre-heat and Energise to Stop functions.
• Low Oil Pressure and High Engine Temperature Shutdown.
• Overspeed and Underspeed (frequency) protection.
• Charge Fail Alarm
• Two fully configurable auxiliary inputs.

All alarms are indicated by high visibility red LED’s.

The module’s microprocessor provides a comprehensive list of timers and configurable functions. Parameter settings can be adjusted using the front panel pushbuttons once in Configuration Mode. Access to the settings is via a small ‘Configuration Switch’ on the rear of the module (see figs. 1 and 2), and enables changes to be made in the field.

Selection of the Configuration Mode is indicated by rapid flashing of the ‘Auto’ LED.

The module is designed with DSE’s proven experience and uses modern construction to provide a high level of reliability and suitability for the intended operating environment. Issues such as environmental compliance and EMC have been carefully engineered into the design. Advanced features such as protected solid state outputs mean that there are no moving parts or contacts to burn out.

The Model 5110 is an Automatic Engine Control Module which has been designed to allow the OEM to meet demand for increased capability within the industry. The module has been designed to automatically start and stop the engine, indicating the operational status and fault conditions, shutting down the engine and indicating the engine failure by means of a graphical LCD display and a flashing LED on the front panel. Selected operational timers and alarms can be adjusted by the customer.

Configuration of the module can be carried out manually utilising the front panel editor, or alternatively by PC, using the 5110 software.

Operation of the module is via pushbuttons mounted on the front panel with STOP, AUTO and MANUAL modes. A further pushbutton provides an LCD DISPLAY SCROLL function to view the instrumentation.

The module features microprocessor control and provides a comprehensive list of timers and pre-configured sequences. This allows most required specifications to be achieved.

Multiple alarm channels are provided to monitor for the following conditions:

• Under/Over speed
• Charge alternator failure
• Emergency stop
• Low oil pressure
• High engine temperature
• Fail to start
• Fail to come to rest
• Loss of speed sensing signal

Additionally any configurable input alarms that have been configured as indication, warning or shutdown. Alarms are indicated by an LCD Icon and LED illumination.

The 5110 series modules have been designed for front panel mounting. The module is fitted into the cut-out with the fixing clips removed. These are then fitted from the rear. Connection is via locking plug and socket connectors.

The 5110 module provides engine and electrical metering facilities via the LCD display with the following instrumentation displays, accessed via the SCROLL push-button:

With the exception of the Emergency Stop Input, these are configurable to be either N/C or N/O contacts, switched to the -ve DC. The five fully configurable auxiliary inputs can be selected to be indication, warning or shutdown inputs either immediate or held off during start up to allow for use as protection expansion inputs.

Alternatively they may be configured to control extra functions such as lamp test or remote start - refer to appropriate manuals for details.

Analogue inputs are provided for Oil Pressure and Engine Temperature. These connect to conventional engine mounted resistive sender units (such as VDO or Datcon Type) to provide accurate monitoring and protection facilities. Alternatively they can be configured to interface with digital switch type inputs for Low oil pressure and high engine temperature shutdowns.
