Warning Operation
Two flashing warning lamps and an alarm inform the operator that: * An ether cylinder is empty.* Both ether cylinders are empty.* A noncritical fault is present.* A critical fault is present.The warning lamps and alarm can be tested by placing the ether system switch in the Test/Disable position. The warning alarm will turn ON for two seconds and the warning lamps will remain ON continuously until the switch is returned to the Auto position. If a solenoid valve is shorted to +BAT, the alarm sounds whenever the key switch is in the RUN or START position. The alarm beeps at the rate of approximately 1.3 seconds ON and 2.0 seconds OFF. The engine could be damaged if ether was injected before the engine is cranked.An Ether Cylinder Is Empty
One of the two warning lamps inform the operator when an ether cylinder is empty. The lamp flashes at the rate of 1.5 Hz (flashes per second) with equal ON and OFF times. The lamps and ether solenoid assemblies are correspondingly marked 1 and 2. When empty ether cylinder warning lamp 1 is flashing, ether cylinder 1 needs replaced. When empty ether cylinder warning lamp 2 is flashing, ether cylinder 2 needs replaced. (On 3516 engines, both ether cylinders of the set need replaced.) The lamps stop flashing when the reset switch is activated during ether cylinder replacement. The empty ether cylinder warning lamp will also flash if there is no ether cylinder installed.Both Ether Cylinders Are Empty
When both ether cylinders are empty (on 3516 engines, both ether cylinder sets), both empty ether cylinder warning lamps and the alarm are activated. Empty ether cylinder warning lamps 1 and 2 flash at the same time, at the rate of 1.5 Hz (flashes per second). The alarm also sounds, during the ether injection time, approximately 1.3 seconds ON and 2.0 seconds OFF.A Noncritical Fault Is Present
When a noncritical fault is present, both empty ether cylinder warning lamps are activated. Empty ether cylinder warning lamps 1 and 2 flash alternately (taking turns ON and OFF) at the rate of 3.0 Hz (flashes per second). The system continues to operate during a noncritical fault.A Critical Fault Is Present
When a critical fault is present. both empty ether cylinder warning lamps and the alarm are activated. Empty ether cylinder warning lamps 1 and 2 flash alternately (taking turns ON and OFF) at the rate of 3.0 Hz (flashes per second). The alarm also sounds, during the ether injection time, approximately 1.3 seconds ON and 2.0 seconds OFF. If possible, ether injections are disabled during a critical fault.Diagnostic Operation
Ether Injection Control DiagnosticsThe ether injection control has diagnostic capabilities to assist in troubleshooting. The control detects and records faults that occur to the system. During a critical fault, if possible, the control disables ether injection. During a noncritical fault, the control takes alternate action so that the system continues to function.The diagnostic display, on the ether injection control, displays a code which represents the fault that
