Trendsetter VLF - System Air Pressure Too Low (error number 15509)

System Air Pressure Too Low (error number 15509)


Product		Trendsetter VLF VLF Platesetter
Component		System air pressure

Error		15509 ALE: System air pressure too low!

Symptoms		The system air pressure measured at the Engine Satellite Electronics (ESE) Board is below the threshold value specified by the nvs parameter "al air_supply_threshold" (al ast).

Cause		Air is turned off. Air is leaking from a hose or filter. The nvs parameter "al ast" is not set properly. There is a problem with the connection between the air pressure system and the Engine Satellite Electronics (ESE) board -- connector J36.

Solution		Check the supply air pressure at the pressure regulator, then: Make sure the air is turned on. Check all air hoses and filters for air leaks. Check the default value for the "al ast" parameter. It should be 60 psig. Verify that connector J36 on the ESE Board is securely in place. Check the condition of the black, red, green and yellow wires. If everything seems normal, the problem may be caused by pressure fluctuations due to insufficient capacity of the air supply system.
