GAUGE-OIL LEVEL 1601993 - Caterpillar

- This means a condition that is not normal. The presence of an abnormal condition or an abnormal signal indicates the existence of a problem. A warning is activated in order to alert the operator.Alert Indicator - An alert indicator is a red indicator lamp that is located on the top portion of the main display module. The alert indicator notifies the operator of an abnormal condition.+Battery - This pertains to any of the harness wiring which is part of the circuit that connects to the positive battery post. +Battery voltage is also referred to as system voltage.Connector Contact - A connector contact is the component of a harness connector that actually makes the electrical connection. Connector contacts are either pins or sockets.Continuity - A complete electrical circuit with a resistance of 5 ohms or lessFault - A fault is a failure of a component in the Electronic Monitoring System. For example, open or shorted harness, faulty switch, sensor or control.Hard Wired - Hard wired refers to an electrical connection that is made within the harness. The connections are permanent. These soldered connections or crimped connections are not meant to be altered.Harness - This is an assembly or a bundle of two or more wires that electrically connects system components. Typically, the harness is held together by a loom.Indicator - An indicator is any of the items within the Caterpillar Monitoring System display area which operate in an ON, FLASHING or OFF manner in order to bring attention to a machine condition.Indicator Fault - An indicator fault is when the operation of an indicator does not correspond to a known machine condition.Normal Condition - Words used with a switch or relay. Their normal condition is their condition when they are not controlled by the application of force, temperature, pressure or electricity. This is usually the condition found with the component installed on a machine. The condition may be different if the component is being tested off the machine (on the bench). Machine electrical system schematics show the condition of components as installed on a machine. Problem - This refers to the presence of an abnormal machine condition. When a problem exists, warning operation is activated and the main display module notifies the operator.Signal Wire - This is the harness wire that carries the signal voltage to the electronic control. The signal is sent by any of the components that are listed here: a sensor, a switch and any other similar components.Specified value - The temperature, pressure, level, flow or position where a switch changes state (closed to open or open to closed). These specifications can be found on the Electrical System Schematic for the machine being serviced. Switch Input - This is an input to an ECM. This input may be ground. The input may be open. The input may be positive voltage (+battery).System Voltage - System voltage is the actual voltage that exists between the positive battery post and the frame ground. The system voltage is referred
