Display Assemblies

DISPLAY ASSEMBLIES

Display LEDs signal the various functions of the electronic shutdown system to the operator or to service personnel. Light emitting diodes (LEDs) are used for this purpose.

The electronic shutdown system display has 13 display LEDs on it as below.

Hi Alarm Methane Lo Alarm Methane

methane level high, shuts down engine. warning that methane level has increased but is still safe, engine keeps running.

Engine Oil Pressure Charge Failure Run Solenoid

shuts down engine. alternator not charging or circuit fault. solenoid turned off, fault with one of the sensors, solenoid fault solenoid circuit fault, shuts down engine. Start Fault engine will start and run normally, but if the start light stays on, there is a problem with the start pressure switch or its cable. When this happens, the oil pressure and coolant flow timers on the control board are affected. The oil pressure and coolant circulation lights will still work normally (i.e. signal low/no oil pressure and low/no circulation) but the engine will not shutdown for ten minutes. The faulty switch or circuit should be repaired as soon as possible. Engine Coolant Temperature shuts down engine. Engine Coolant/Hydraulic Oil Level Low shuts down engine. Low Exhaust Conditioner Water Shutdown shuts down engine. Low Exhaust Conditioner Water Shutdown shuts down engine. Exhaust Outlet Gas Temperature shuts down engine. Pre-Exhaust Filter Gas Temperature shuts down engine. Spare 1 additional sensor may be added to the system, shuts down engine.

Battery Voltage Low

Methane Fault

all lights flash (engine will keep going for a time, but system needs attention). one or both methane alarm lights flash engine shuts down but not due to presence of methane. Any Sensor or Cable Fault relevant light flashes, shuts down engine. All LEDS Flashing One on Steady battery charge level low, steady light indicates that there is a sensor fault, shuts down the engine. Every time the electronic shutdown system is first switched on, all the display LEDs light up for about five seconds thus checking their functionality. The single diagnostic light on the main control board shows that power is applied to the board.

GENERAL ARRANGEMENTS

The shutdown system consists of a :

 Main control box  IS battery  Display panel  Methane head  Low hydraulic oil level sensor  Low engine coolant level sensor  High engine coolant temperature  Low engine oil pressure  Start reset switch  Start initiate switch  Low water shutdown switch (2 off)  Exhaust outlet gas temperature  Run solenoid  Pre-exhaust filter gas temperature  Methane bypass switch  Trolex convertor

These sensors and switches are connected via a number of cables.
