VOLTAGE COMPENSATION ADJUSTMENT

STARTRACS are all pre-adjusted at the factory to cover a wide range of line voltages However,
there are cases where the incoming power to a facility are out of the voltage compensation ran ge
of the STARTRAC. If the incoming voltage is too low, a "SPd Error 2" will be displayed. If the volt -
age is too high, the STARTRAC will run faster than 1 MPH ( 2 km/hr On metric systems) when
commanded to minimum speed

For optimal performance of the STARTRAC, check the voltage compensation after initial assembly and whenever the symptoms listed above occur. The procedure is as follows:

A. Switch off main power.

B. Enter motor test mode by holding down the [8] key while switching on power to the
treadmill.

NOTE With the exception of speed, the displays in motor test mode indicate functions
differing from those labeled on the panel.

DO NOT STAND ON THE RUNNING BELT WHEN PERFORMING THE STEPS BELOW:

C.   The center numerical display reflects a speed command value. Initially, this value should
be the number 3 (minimum command). The running belt should be at a stop. If not, VR2
on the motor control board must be adjusted (see location diagram). With a small

screwdriver, slowly adjust VR2 counter-'clockwise just until the belt stops.

D.   Set the command to 18 using the [FAST] key to increase ([SLOW] to decrease). Verify
that the running belt moves at least 1" (25.4 mm) per second. If not, adjust VR2 in the
clockwise direction until it does.

E.    Return the command to 3 using the [SLOW] key to decrease. If the belt is not at a stop,
repeat steps (C) through (E).

F.  Exit motor test mode either pressing the [STOP] key or switching main power off.
