Optional Equipment - Section 6 OM6008 02/03 Page 6-4 Payload Meter III Component Description the overload limit is 10,000 psi (700 kg/cm 2 ). One wire to the sensor is the supply voltage and the other is the signal. The 0-4000 psi range is converted into an electrical current between 4-20 ma. The supply voltage for the sensor is nominally +18vdc. Each pressure sensor has an 90" length of cable that is terminated with #10 ring terminals. The cable is specially shielded and reinforced to provide mechanical strength and electronic noise immunity. A typical part number for the pressure sensor is PC0328. used for speed and can display metric (km/h) or English (mph) units.
Grounding terminal #4 on the back of the speedometer will switch the meter to display metric units. Leaving terminal #4 unconnected will cause the gauge to display English units. The speedometer can be adjusted using a calibration potentiometer in the back just like existing speedometers. The payload meter uses the lower display for payload information. The normal display mode shows the current payload. The display can be changed to show the load and total tons counter or the Operator ID. Using the operator switch on the dash panel, the current suspension pressures and incline can be displayed. The units for display are set using the PC software.
Payloads can be displayed in Short Tons, Long Tons or Metric Tons. A typical part number for this gauge is the PC0550. Inclinometer The inclinometer is used to increase the accuracy of load calculations on an incline. The inclinometer uses three wires. For the sensor, red is the +18vdc supply voltage, black is ground and the white is the signal. The incline signal is a voltage between 1 and 4 volts. Zero degrees of incline is represented by 2.6vdc on the signal line. The voltage signal will be decreased by 0.103vdc for every degree of nose up incline. A typical part number for the inclinometer assembly is 7861-92-5330.
