[. . . ] NOTE:- This will only occur if the speed sensing signal is lost during cranking or during the safety on timer. If the signal is lost during normal operation the Generator will shutdown with an Under-speed alarm. 14 057-012 G7659 OPERATING MANUAL ISSUE 5. 1 18/06/2007 AM DSE Model G7659 Automatic Mains Failure & Instrumentation System Operators Manual 4. 5 HIGH CURRENT SHUTDOWN ALARM GENERATOR HIGH CURRENT, if the module detects a generator output current in excess of the pre-set trip a warning is initiated. This warning will continue for a period of time depending upon the level of overload that the generator is subjected to, and the configuration setting for Generator High Current in the 5200 series configuration software. For instance the factory default settings for Generator High Current allow for a loading of the generator to 110% for one hour. That is to say if the generator load level exceeds the trip point by 10%, a warning alarm will occur while the overload condition exists. If the load level does not drop to normal levels within one hour, the set is stopped, the G7659 module displaying either shutdown alarm or electrical trip alarm depending upon module configuration. Additionally, the A icon will illuminate. NOTE:- Higher overload levels will result in a faster acting shutdown condition. For instance with the factory default configuration, an overload level twice that of the trip level ( typically 200%) will result in a Generator High Current shutdown condition after 36 seconds. For details of the relationship between the overload and the shutdown time, please see the Appendix section of this manual. 4. 6 ELECTRICAL TRIPS Electrical trips are latching and stop the Generator but in a controlled manner. On initiation of the electrical trip condition the module will de-energise the `Close Generator' Output to remove the load from the generator. Once this has occurred the module will start the Cooling timer and allow the engine to cool off-load before shutting down the engine. In this example the hours run time would read 21 hours and 35 minutes. HOURS RUN (100 hrs +) The hours run up to and including 99 are displayed on the third line of the display. the hundreds, thousands and tens of thousands units) are displayed on the second line of the display. In this example the hours run time would read 221 hours and 35 minutes. the hundreds, thousands and tens of thousands units) are displayed on the second line of the display. In this example the hours run time would read 3221 hours and 35 minutes. 18 057-012 G7659 OPERATING MANUAL ISSUE 5. 1 18/06/2007 AM DSE Model G7659 Automatic Mains Failure & Instrumentation System Operators Manual 6. 2 LCD DISPLAY AREAS Instrument values Display information & units of measure Alarm icons Status icons User configurable display icons G7659 OPERATING MANUAL ISSUE 5. 1 18-Jun-07 AM 19 DSE Model G7659 Automatic Mains Failure & Instrumentation System Operators Manual 6. 3 VIEWING THE INSTRUMENTS It is possible to manually scroll to display the different instruments by repeatedly operating the scroll button. Once selected the instrument will remain on the LCD display until the user selects a different instrument or after a period of inactivity the module will revert to the initial display (Hz/RPM). Instrument Page Order:· Generator RPM / Frequency (Hz) · Generator AC Voltage Line-Neutral · Generator AC Voltage Line-Line · Oil Pressure · Coolant temperature · Fuel level (%) · Engine Hours Run · DC Battery Voltage · AC Line Current · Total kW · Total VA · AC phase angle (cos ) · Mains (Utility) Frequency (Hz) · Mains (Utility) AC Voltage Line-Neutral · Mains (Utility) AC Voltage Line-Line Manually Selecting an Instrument Initial display (Hz/RPM) Pressing the DOWN button the LCD will then show (Generator L-N voltages) Pressing the DOWN button the LCD will then show (Generator L-L voltages) button again will scroll through each individual instrument eventually returning to the original Pressing the instrument displayed. NOTE:-Once selected the instrument will remain on the LCD display until the user selects a different instrument or after a period of inactivity the module will revert to the initial display. 20 057-012 G7659 OPERATING MANUAL ISSUE 5. 1 18/06/2007 AM DSE Model G7659 Automatic Mains Failure & Instrumentation System Operators Manual 6. 4 VIEWING THE EVENT LOG The model G7659 remote start module maintains a log of the last 15 shutdown alarms and mains fail/returns to enable the operator or engineer to view the past alarms history. Only shutdown and electrical trip alarms are logged; warning alarms are not logged. Once the log is full (15 shutdown alarms), any subsequent shutdown alarms will overwrite the oldest entry in the log. The alarm is logged, along with the date and time of the event in the format shown in this example. [. . . ] Refer to technical data sheet on the 157 relay module for further details. 15. 6. 2 LED OUTPUT EXPANSION (548) An expansion module is available, which connects to the configuration socket, and enables the 5210 to use eight additional LED's, providing remote LED indication up to 50 metres away. Refer to technical data sheet on the 548 LED module for further details. It is possible to use a mix of 157 and 548 modules to give both relay and LED expansion of the same 8 items if required (Please refer to our Technical Support department for details. ). 15. 7 INPUT EXPANSION It is possible to increase the number of monitored inputs available by utilising a DSE 540/541 Protection Expansion/Annunciator. Please refer to our Technical department for details. 15. 8 STANDBY GENERATING SET? The 5210 needs to be given a remote start signal to initiate an engine start. [. . . ]
