(5) The engine and hydraulic parameters are displayed on two engine
instrument panel(ELS)using light emitting diodes(LED). Engine displays and controls on the center panel consist of the following : ·N1 displays—— indicate fan speed in percent rpm. ·N2 displays —indicate high pressure compressor speed in percent rpm . ·Exhaust gas temperature(EGT)displays
1. indicate temperature of exhaust gas in °C.
2. a red light above each N1,N2,and EGT display illuminates if that engine
exceed its redline. ·Fuel flow displays Indicate fuel flow in weight of fuel per hour and also total fuel consumed per engine. The FUEL FLOW/FUEL USED switch is used to change display from FUEL FLOW to FUEL USED, after 10 seconds the FUEL USED display reverts to FUEL FLOW. ·The FUEL USED RESET display a sequence:fuel used since last trset or power— up, then 000, and finally fuel flow. ·Engine oil pressure displays —display engine oil pressure in psi. ·Engine oil temperature displays— display engine oil temperature in°C. ·Engine oil quantity displays —display oil quantity of engine in percent of full. ·Engine vibration displays —display engine maximum vibration. ·Hydraulic pressure displays —display hydraulic systems pressure in psi. ·Hydraulic quantity displays —display hydraulic system quantity in % of full.
發(fā)動機及液壓參數(shù)用發(fā)光二極管顯示在兩個發(fā)動機指示面板上。發(fā)動機在中央面板上顯示及控制包括以下內(nèi)容：
·
N1顯示—用轉(zhuǎn)速百分比指示風扇轉(zhuǎn)速
·
N2顯示—用轉(zhuǎn)速百分比指示高壓壓氣機轉(zhuǎn)速。
·
排氣溫度指示
1. 用°
C指示排氣溫度。
2.
如果發(fā)動機超出紅線， N1，N2上方的紅燈及發(fā)動機排氣溫度指示燈亮。
·
燃油流量指示用每臺發(fā)動機每小時總的消耗重量指示燃油量。 FUEL FLOW/FUEL USED開關(guān)用于改變 FUEL FLOW/FUEL USED的顯示模式， 10秒后 FUEL USED顯示恢復(fù)到 FUEL FLOW。
·FUEL
USED RESET—顯示一個順序：上次重置后上電后的燃油使用，然后是 000，最終燃油流量。
·
發(fā)動機滑油壓力指示—用 PSI指示發(fā)動機滑油壓力。
·
發(fā)動機滑油溫度指示—用° C指示發(fā)動機滑油溫度。
·
發(fā)動機滑油量指示—用百分比顯示發(fā)動機滑油量。
·
發(fā)動機振動值指示—顯示發(fā)動機最大振動值。
·液壓指示—用
PSI顯示液壓系統(tǒng)壓力。
·
液壓油量顯示—用百分比顯示液壓油量。
