Self-test
MODE
On power-up
, the UPS 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. Note that it is not possible
to enter self-test using the USB port. If the RS-232 lines are determined to be shorted, the UPS enters the Self-
test Mode. During the Self-test Mode, 14 stages of speed and elevation set points are used to exercise the inputs
and outputs. Upon completion of each new set point, 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:

CALIBRATION
Both a speed and an elevation calibration method are provided in the UPS software. The elevation
calibration requires manually adjusting the deck to find the sensor counts for 7 fixed elevation positions
and is not recommended for field adjustment without special treadmill interface software. During speed
calibration, the speed reference output is swept across its range and speed measurements are made at 15
points. This function is also only available through the use of special treadmill interface software.
DIP SWITCH SETTINGS
A dip switch is located on the UPS at location SW2. An ar
row indicates the “ON” position, and each
switch is numbered 1-4. Currently, only two of the switches are read by the UPS, and both are only
checked on
power-up
so changing the switches while the system is running will not have an effect until
power is cy
cled. Switch 1 is the Unit selection switch. When in the “OFF” position, units are set to
English, and in the “ON” position, units are set to metric. Switch 2 is a long timeout option. When Switch
2 is in the “OFF” position, a communication disconnect s
top timeout is 2.5 seconds, but when switch 2 is
in the “ON” position, the communication disconnect stop timeout is extended to 4 seconds. Position Dip
Switch 3 (Firmware
Version 1.43 & later FGLF0495 Smart Power Supply): When in the “OFF” position
for Tra
ckmaster Interface Protocol, in the “ON” position New Customer Interface Protocol.
Dip Switch 4
in the
“OFF
”
position for factory use only.
Additional dip switch on UPS (Firmware Version 1.1812 and later FGLF-4953-03 Smart Power Supply).
This configuration has 1-6 number switches, position 1 thru 4 are same as (FGLF0495-1 Smart Power
Supply). When retrieving system flash log file switch configuration 1,2,3,4, and
6 are in the “OFF position
and switch 5 is in the “ON” position. Refer to “Log
