INTRODUCTION
The Auto Pump Status Center is an air pressure sensor with indicator that displays air pressure in
pounds per square inch (PSI). The indicator contains a 2.5-digit numerical display and bar graph. The
PSI indicator works in conjuction with an air pressure sensor. The air pressure sensor port can be
connected to an air supply to measure and display PSI. Additionally, a 3.5-digit display measures and
displays battery voltage.
The indicator is designed to be mounted on the exterior of a vehicle so that the battery voltage and PSI
condition may be easily viewed. The indicator fits the Kussmaul standard indicator panel cut out.
FEATURES
I. PUMP PLUS STATUS CENTER
• Pressure sensor interface with 5/32 air supply input port
• 2.5-digit PSI display
• 3.5 digit VOLTAGE display
• Battery status LEDs
• 4-segment bar graph
II. AIR SUPPLY
A 5/32 air supply input port is used to connect air supply to the pressure sensor interface and a 1/8
NPT is provided for connecting to the air tank.
III. NUMERICAL DISPLAYS
A 2.5-digit display provides a PSI reading of the supplied air pressure; additionally a 3.5-digit display
provides a voltage reading of the systems battery voltage.
IV. BATTERY STATUS LEDs
4 LED’s provide battery condition status: Hi Voltage, Charged, Charging, and Low Voltage.
V. BAR GRAPH
The 4-segment bar graph is a graphical representation of the aire supply condition. The bottom bar
will flash if the supply pressure is below 50 PSI. All bars are illuminated when the pressure reaches
150 PSI.
OPERATION
The 091-198-12-PP consists of a pressure sensor interface and indicator to measure and display PSI
and battery voltage. A bar graph on the indicator provides a graphical representation of the air supply
condition, while LEDs provide information on the condition of the battery.
During operation, the pressure sensor continuously monitors the air supply present at the air input port.
The pressure sensor then genarates an analog signal, which is then sent to the indicator. The indicator
then convertes the analog signal to the digital display. A 2-pin terminal connector is used to supply power
to the pressure sensor interface. Additionally, a 4-pin terminal connector is used to interface the indicator
with the pressure sensor. The 4-pin terminal provides power and pressure sensor signal to the indicator.
Whenever the monitored air supply drops below 50 PSI the bottom bar graph LED will flash indicating
low pressure. The 4-segment bar graph is fully illuminated when the air supply reaches 150 PSI.
