Instruments and Controls Identification medium-frequency tone sounds when the vol- ume control level is changed. Successful down- loading of Eaton Vehicle Information Manage- ment System (EVIMS) data will cause a double tone to sound. Unsuccessful downloading will cause a low-frequency tone to sound. Special Road Situations WARNING The Eaton VORAD EVT–300 Collision Warning System (CWS) is intended solely as an aid for an alert and conscientious professional driver. It is not intended to be used or relied on to operate a vehicle. Use the system in conjunction with rear- view mirrors and other instrumentation to safely operate the vehicle. This system will not warn of many possible hazards.
Do not assume it is "all clear" if no alert lights are illuminated. 14. A failure of the optional side sensor(s) will cause a continuous red light on the side sensor display to appear. Side Sensor Display, Optional 1. The yellow indicator light illuminates continuously when no vehicle is detected by the side sen- sor(s). See Fig. 2.25 . Failure to drive safely and use the system prop- erly could result in personal injury and/or death and severe property damage. Certain special road situations may affect the sys- tem’s ability to detect objects. These situations in- clude the effects of curves, dips, and hills which can provide an unexpected result: 1 NOTE:
A warning may sound when an object is detected in front of the vehicle even though the driver intends to turn away or stop before reach- ing the object. 2 3 When an object is detected in a very sharp right- or left-hand turn, the audible alarm will not sound. When approaching a curve, before turning into it, alarms may sound and lights illuminate be- cause of an object off of the road, directly in line with your vehicle. This will not occur when the brakes are applied. 01/27/97 f601259 1. Red Alert Light (vehicle or object detected) 2. Photo Light Sensor 3.
Yellow Indicator Light (no vehicle or object detected) Elevated obstacles, such as overpasses and overhead signs, may be detected when ap- proaching a roadway descending to a lower elevation. Fig. 2.25, Side Sensor Display, Optional 2. The photo light sensor senses lighting conditions in the cab and automatically adjusts the intensity of indicator and alert lights. Vehicles cannot be detected on the other side of a hill. An alarm will not sound until the object is within the antenna assembly’s field of view. 3. The red alert light illuminates when objects are detected by the side sensor(s).
If the right turn signal is activated and the side sensor detects an object, the red alert light will illuminate and the DDU speaker will sound a high-frequency double tone. This tone is sounded only once per activation of the turn signal. The red light will also illuminate and stay on if a failure of the side sensor is detected. On approaching a steep hill, objects above the beam cannot be detected. Generally, the beam hitting the road surface does not cause an alarm. 2.23
