Self Test Mode; Calibration - Trackmaster FVX325 Field Service Manual

SELF TEST MODE

On powerup, the SPS sends out a special test character 'T' and checks to see if it is returned.
This is a check for a shorting jumper across the transmit and receive lines of the RS-232
serial port. If the lines are determined to be shorted, the SPS enters the self test mode.
During the seft test mode, 14 stages of speed and elevation setpoints are used to exercise the
inputs and outputs. Upon completion of each new setpoint, another character is sent out and
the process is repeated to advance to the next stage. In this way, the shorting jumper can be
removed at any point to stop the staging process. The following table shows the sequence of
self test stages :
Stage Incline Speed (mph)
1 5%
2 10%
3 15%
4 20%
5 20%
6 20%
7 20%
8 20%
9 20%
10 15%
11 10%
12 5%
13 0%
14 0%

CALIBRATION

Both a speed and an elevation calibration method are provided in the SPS software. The
elevation calibration automatically puts the deck in the zero elevation position and zeros the
counter. The deck is then automatically raised to the limit position and the count is taken to
be 25% elevation. During speed calibration, the speed reference output is adjusted to find
speed references for 5 target speed settings. Both of these calibration procedures are accessed
through the serial port using special software provided to the manufacturer by PMI.
