heavy user runs at a high incline, the weight of the user has the potential to push the running
belt to go faster than the commanded motor controller speed (generates excess current). The
dynamic brake circuit senses the load variations and applies a braking force within the motor.
The system utilizes an external power resistor (Dynamic Brake resistor) to absorb the excess
generated current and determine applied braking force. Power Factor Correction is a feature
that attempts to reduce power consumption. The system monitors that this power factor is held
within certain parameters. If it falls outside those parameters (the system is using more current
than expected), the system will flag an ERROR 29.
Auto Stop
The Auto Stop feature monitors up and down movement of the deck. The deck motion indic-
ates a user is present. The lack of motion indicates that a user is not present. If the running belt
is moving and the Auto Stop does not detect motion from the running deck, the Auto Stop fea-
ture will stop the motion of the running belt.
GEN 06 treadmills (Mfg. date: April 2006 to April 2011) do not support the auto-stop feature.
TRM10 treadmills (Mfg. date: April 2011 and later) do support the auto-stop feature.
The auto-stop feature consists of a magnet mounted on the edge of the deck, the sensor moun-
ted on the roller mounting bracket and a cable connecting Auto-stop to the console. When a
user is running on the deck, it causes the magnet to be in motion relative to the sensor. When a
program is entered, Quick Start is pressed or the treadmill has been resumed after being
paused, the treadmill starts at 1 mph. The user will then have 60 seconds to enter any remain-
ing workout settings before motion detection begins. Once motion detection has commenced
and if no or very little motion is detected, the Auto Stop feature interprets that the treadmill is
no longer in use. The Auto Stop feature will continue to monitor the treadmill for motion for 30
seconds; if motion is still not detected a 10 second count down will be displayed on the con-
sole. After the 10 second count down has elapsed and motion has not been detected, the Auto
Stop feature will stop the motion of the running belt and go into pause mode. If motion is detec-
ted within the 10 second count down cycles the shutdown feature will be aborted.
The Auto Stop feature can be enabled or disabled within the service software Club Para-
meters, see .
NOTE: When Auto Stop is enabled, running belt adjustment and tracking procedures
should be performed in the Hardware Validation – Belt Speed Test because the Auto-
Stop feature is not active during the Belt Speed Test, see
