General Information
Features
• Lamp on when tires 10% low (programmable)
• Checks tire pressure every 10 minutes
• Non-pressurized lines and seals when not inflating
• Warning lamp on only when service is required (not
every inflation)
• Does not pressurize axle tube (prevents contamina-
tion of air seals)
• Seal and line leaks will not pressurize wheel ends
• No venting at wheel end prevents contamination
from entering hubcap
• Check-valves located in tire hoses
• Industry standard data link (SAE J1587) for commu-
nications and service
• Historical information retained through power-ups
• Leaky tire detection
• Automatic pressure target learn mode
• Serviceable filter at manifold keeps lines and seals
clean
• System detects and logs service code if no supply air
for greater than 24 hours
Data Logging
• Active and historical service codes (clear after 50
resets without reoccurrence)
• Count of inflation events
• Total inflation time
• Total hold time (pressurized)
• Count of power resets
• Total powered time
• Inflation time histogram data
• Pressure below target histogram data
