The icon will illuminate. LOW OIL PRESSURE If the module detects that the engine oil pressure has fallen below the low oil pressure trip setting level after the Safety On timer has expired, a shutdown will occur. The icon will illuminate. HIGH ENGINE TEMPERATURE If the module detects that the engine coolant temperature has exceeded the high engine temperature trip setting level after the Safety On timer has expired, a shutdown will oc- cur. The icon will illuminate. OVERSPEED / OVERFREQUENCY If the engine speed exceeds the pre-set trip a shutdown is initiated. The icon will illuminate. Overspeed is not delayed, it is an immediate shutdown. UNDERSPEED / UNDERFREQUENCY If the engine speed falls below the pre-set trip after the Safety On timer has expired, a shutdown is initiated. The icon will illuminate. OIL PRESSURE SENDER OPEN CIRCUIT If the module detects a loss of signal from the oil pressure sender (open circuit) a shutdown is initiated. The LCD will indicate:(Steady) (And .-----. on the engine oil pressure in- strument). Sender failure is not delayed, it is an immediate shutdown. AUXILIARY INPUTS, if an auxiliary input has been configured as a shutdown the appropriate LCD segment will be dis- played: LOSS OF SPEED SIGNAL If the speed sensing signal is lost during cranking, a shut- down is initiated. The icon will illuminate (Steady). As engine speed cannot be determined, the entire .fail to stop. timer is observed before the alarm can be reset and the engine restarted. 7.4. DESCRIPTION OF CONTROLS. The following section details the function and meaning of the various controls on the module. Page 19 Typical LCD screens Instruments The LCD displays the various engine parameters such as .ENGINE SPEED‘, .OIL PRESSURE‘, .HOURS RUN‘, etc. Each instrument is displayed with the appropriate units of meas- ure. In this example, the values being displayed are Generator phase to phase AC voltages Alarm Icons The LCD also dis-plays the exact nature of any alarm condition that may have occurred such as LOW OIL PRESSURE using appropri- ate icons. This allows very specific alarm conditions to be brought to the operators‘ attention. Refer to the .Protections‘ section of this manual for details of the alarms. User Defined Indications The LCD displays the user-defined indications when config- ured and active. The icons will illuminate and point to the appropriate text insert label. These indications can be used to indicate internal states (i.e. Engine Running, Safety On, etc). User Defined Alarms The LCD displays the user-defined alarms when configured and active. The icons will illuminate and point to the appro- priate text insert label. These alarms can be used to indi- cate the operation of external alarms (i.e. .Low Fuel Level‘, .Low Coolant level‘ etc) or to indicate internal alarms (i.e. Fail to Stop, MPU fault, etc). LCD Display Areas NOTE:- The Engine Hours Run counter will only display the accumulated hours to the nearest 12 Minutes (0.2Hr). The accumulated time will be recorded in HH:MM however. CAUTION: If the DC supply to the module is interrupted the hours run counter will not remember any .undisplayed‘ minutes accu- mulated since the last 12 Minute display update. i.e. 10 Hours 38 Minutes accumulated before DC supply is removed… (10.6 Hours displayed) would become …10 Hours 36Minutes on restoration of DC supply. (10.6 Hours still displayed) This will only occur in the event of a total DC supply break and will NOT occur if the module is simply switched to the Stop/Reset position. VIEWING THE INSTRUMENTS Page 20 It is possible to manually scroll to display the different in- struments 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).
