Figure 6. Engine Operating Panel
The defi nitions below describe the controls and functions of the Engine Operating Panel (Figure 6).
1.Oil Pressure Gauge – During normal operation this gauge be should read between 35 to 65 psi. (241~448 kPa). When starting the generator the oil pressure may read a little higher, but after the engine warms up the oilpressure should return to the correct pressure range.
2.Water Temperature Gauge – During normal operation this gauge be should read between 180° and 221°F. (82° C and 110° C
3.Charging Ammeter Gauge – Indicates the current being supplied by the engine’s alternator which provides current for generator’s control circuits and battery charging system.
4.Fuel Gauge - Indicates amount of diesel fuel available.
5.Tachometer – Indicates engine speed in RPM’s for 60 Hz operation. This meter should indicate 1800 RPM’s when the rated load is applied. In addition a built in hour meter will record the number of operational hours that the generator has been in use.
6.Panel Light – Normally used in dark areas or at night time. When activated, panel lights will illuminate. When the generator is not in use be sure to turn the panel light switch to the OFF position.
7.Panel Light Switch – When activated will turn on control panel light.
8.Engine Speed Switch – This switch controls the speed of the engine (low/high).
9.Diagnostic Display – This display monitors crtical engine functions. If any abnormal conditions occur, an Active Fault Code will be displayed. This diagnostic display can be located inside the control box
