5.1 Program Functions

If the battery voltage drops below the defined Battery Voltage Lower Limit (P04), an alarm occurs and “Low Battery Failure” LED illuminates.

P02 Speed Lower Limit P03 Speed Upper Limit P28 Speed Fault Control Delay

A fault will be reported if the alternator output frequency goes outside the window defined by the upper and lower limits for more than the time defined as the Alternator speed fault control delay (P28). The fault will only occur if the engine has started to run and has been running for the period defined as the Control on Delay (P26). This failure immediately stops the generating set without Engine Cooling Time (P29)

P00 Alternator Voltage Lower Limit P01 Alternator Voltage Upper Limit P27 Alternator Voltage Fault Control Delay

A fault will be reported if the alternator output voltage goes outside the window defined by the upper and lower limits for more than the time defined as the Alternator Voltage Fault Control Delay (P27). The fault will only occur if the engine has started to run and has been running for the period defined as the Control on Delay (P26). This failure immediately stops the generating set without Engine Cooling Time (P29)

5.1.1 Alternator Voltage

5.1.2 Alternator Frequency

5.1.3 Battery Voltage Lower Limit (P04)

P06 Periodic Maintenance Hour Set Value P07 Periodic Maintenance Hour Reset

To ensure reliability, the engine must be serviced at regular intervals. The unit can be set to indicate when a service is due. Set Periodic Maintenance Hour Set Value (P06) to the number of running hours between services. Use Periodic Maintenace Hour Reset (P07) to reset the hours counter at each service. When the engine has run for the defined number of hours, the alarm LED will flash and when the alarm display option is selected, the display will show the error message bAEr.

5.1.4 Maintenance Indication

This parameter specifies the method to read generator frequency. The choice is between alternator frequency and external magnetic pick-up. Frequency and speed is monitored so as to detect when engine has started and if there is a generator frequency failure. See Sections 5.1.2 Alternator Frequency, 5.1.8 Engine started signals (P18) and 5.1.10 Engine Starting.Speed Limit for Crank Disconnection (P22) should be set to the frequency that must be achieved at start-up. When magnetic pick-up is using Tooth Number (P13) must be entered correctly. Nominal Alternator Frequency (P11) and Nominal Speed (P12) are used to compute alternator RPM or frequency. If Speed Sensing Input Selection (P15) ise set to 0 (from Alternator Voltage), the unit uses Nomainal Alternator Frequency (P11) and Nominal Speed (P12) to calculate RPM from the measured frequency of the alternator voltage. If Speed Sensing Input Selection (P15) is 1 (from Magnetic Pick-up), the unit uses Nominal Alternator Frequency (P11) and Nominal Speed (P12) to calculate alternator output frequency from the measured RPM.

5.1.5 Speed Sensing Input Selection (P15)

This parameter allows the use of either a Stop solenoid or a Fuel solenoid. (See Section 5.1.10 Engine Starting.)

If Fuel Solenoid selected, the fuel solenoid will be energised while the engine is running and deenergised to cut off the fuel and stop the engine. If Stop Solenoid selected, the stop solenoid is normally de-energised and only energised to stop the engine. The solenoid remains energised for the period defined as the Stop Magnet Energising Time (P17). See Section 5.1.10 Engine Starting.

This parameter sets the period for which the Stop solenoid is energised to stop the engine. It applies only where parameter Stop / Fuel Solenoid Selection (P16) is set to Stop Solenoid. See Section 5.1.6 Stop/Fuel Solenoid Selection (P16)

5.1.6 Stop / Fuel Solenoid Selection (P16)

5.1.7 Stop Magnet Energising Time (P17)

Battery Voltage Weak Limit (P19) Battery Voltage Weak Control Time (P20)

If the battery voltage drops below the level specified by the Battery Voltage Weak Limit (P19) for more than the Battery Voltage Weak Control Time (P20) during engine cranking an alarm occurs. The message Weak Battery is displayed on the LED display. Use the Reset Button to clear the alarm indication.

5.1.9 Battery Voltage

5.1.8 Engine Started Signals (P18)

The unit must de-energise the Start solenoid to disconnect the starter motor, once the engine is running. Conversely, if the engine does not start after the pre-set start time, the unit will turn off the starter motor and try again. Hence, the unit must be able to detect when the engine has started. Four signals are available to provide engine running information as follows :

0. Charge generator (P18.0); f r o. m charging generator energising coil current.

1. Speed (P18.1); if engine speed is higher than Speed Limit for Crank Disconnection (P22), pay

attention to the Speed Sensing Input Selection (P15) (Refer to 5.1.8)

2. Alternator Voltage (P18.2); if alternator voltage is higher than Alternator Voltage Limit for Crank Disconneciton (P21)

3. Oil pressure (P18.3); it looks if oil pressure switch is closed. Any or all of these signals can be selected for use. It is advisable to select at least two of them –preferably 1. Engine speed, 2. Charging generator or Alternator voltage. See Section 5.1.10 Engine Starting. If any of the selected signals appears, the unit assumes that the engine has started.

Number of Starting Attempts (P23) Starting Attempt Duration (P24)

After that the unit energises the start solenoid to drive the starter motor and energises the Fuel solenoid, the starting sequence commences. If the preheating output has been configured (see section 5.1.15 Configurable Outputs), the display will show the HEAT message for the time period set by Preheat Time (P09). After that the unit energises the start solenoid to drive the starter motor and energises the Fuel solenoid (if selected – see Section 5.1.6 Stop/Fuel Solenoid selection (P16)) to provide fuel for the engine. If the unit detects that the engine has started, it de-energises the starter motor. Engine start signals are defined by parameter P18 – see Section 5.1.8 Engine started signals (P18). Starting Attempt Duration (P24) defines the maximum period for which drive will be applied to the starter motor. If the unit does not detect engine starting within this period, it cuts off the drive to the starter motor and de-energises the fuel solenoid, if selected. It then makes a new attempt after a delay equal to twice the defined Starting Attempt Duration (P24). Number of Starting Attempts (P23) defines the number of unsuccessful tries that the unit will make before abandoning the attempts. If all these attempts fail, further operations are locked out and a Failed to Start indication is displayed. The unit remains locked until the reset button has been pressed.

5.1.10 Engine Starting

This sets the delay before a Low Oil Pressure warning will be generated. The Low Oil Pressure fault indicator will light if the oil pressure switch contact remains opened, while the engine is running, after the period defined by parameter. This period begins when the EAOM-6 has detected engine starting and has cut off the drive to the starter motor. This failure immediately stops the generating set without Engine Cooling Time (P29).

5.1.11 Oil Pressure By-Pass Time (P25)

During the initial period after the engine has been started, there can be fluctuations in engine speed and alternator output that could generate spurious fault indications. Control On Delay (P26) defines a period during which any fault indications, except High Temperature, will be ignored by the unit. This period begins when the EAOM-6 has detected engine starting and has cut off the drive to the starter motor.

5.1.12 Control On Delay (P26)

Engine Cooling Time (P29) defines the duration of the cooling-off period. When operating under heavy load, the engine can get very hot and is only prevented from overheating by circulating coolant. If the engine is stopped abruptly under these conditions, it can overheat as the coolant flow is cut off. Where the unit controls the load, via one of the configurable outputs, it can ensure that the engine continues to run after the load has been removed.

5.1.13 Engine Cooling Time (P29)

Configurable Failure Input-1 (P31) Configurable Failure Input-2 (P32) Configurable Failure Input-3 (P33)

A contact closure to 0V on any of these inputs causes the horn to sound for the period programmed by Horn Duration (P08) and lights the appropriate indicator on the panel. The unit can be programmed to respond in one of four ways:

0. Indication is unlatched-the LED flashes and horn is sounding while the input is 0V. If the input is not 0V the led will cancel flashing and horn sound.

1. Indication is latched when the input is 0V then, the led flashes and horn is sounding then stays on until the Reset button is pressed.

2. This is the same as 1 but in addition the engine is stopped.

3. Contactor releaser. It is valid only if the load transfer permit output is selected in configuration

outputs 1 and 2.

5.1.14 Configurable Inputs

Configurable Output-1 (P35) Configurable Output-2 (P36)

When active, this output provides battery voltage (12VZ or 24VZ) and can be programmed in one of fourteen different ways:

0. Alarm output. Active when any fault is reported. It can be used for either audible or visual alert.

1. Engine running. Active while the engine is running

2. Load transfer permitted. This output is active while engine is start to run and Control on Delay

(P26) expired and Alternator output voltage is between Alternator Voltage Upper Limit (P00) and Alternator Voltage Lower Limit (P01). This output can be used to control a contactor that transfers

the load to the alternator once the generator set is up and running.

3. Preheat function. On starting the output is active for time period defined in Preheat Time (P09) prior to running the starter motor.

4. Over speed

5. High temperature

6. Low oil pressure

1. Find and fix the fault.

2. Press the Reset button to enable a restart.

3. Press the Engine Start button

In addition to the indicators on the center panel, the Alarm LED will flash in the event of a fault. To discover the fault being reported by the Alarm LED, press repeatedly until the Alarm option has been selected. The display will indicate the fault condition, as follows:

This LED flashes if the engine has not started after the programmed Number of Starting Attempts (P23). The unit must be reset, by pressing the Failure Reset (9) button, before a fresh attempt can be made.

This LED flashes if the thermostatic switch on the engine indicates high temperature. If this fault occurs, the EAOM-6 will stop the engine without any Engine Cooling Time (P29).

This LED flashes if the Oil Pressure Switch on the engine indicates low oil pressure while the engine is running. To obtain this indication, the engine must have been running for at least the period specified by the Oil Pressure By-Pass Time (P25). If this fault occurs, the EAOM-6 will stop the engine without any Engine Cooling Time (P29).

This LED flashes and the horn sounds if the output from the battery charge generator fails after the engine has started. The fault will not be indicated if it occurs within the period defined by the Control On Delay parameter (P26) after the engine has started. This failure will not shut down the engine.

This LED flashes if the alternator speed goes outside the values defined by the Speed Lower Limit (P02) and Speed Higher Limit (P03) parameters. For a fault to be indicated, the speed must be outside these limits for longer than the period defined by the Speed Fault Control Delay parameter (P28). Alternator speed is measured either by measuring alternator output frequency or by monitoring an external magnetic pick-up as selected by program Speed Sensing Input Selection parameter (P15). This failure immediately stops the generating set without any Engine Cooling Time (P29)
