Error 17
– DB Resistor Thermal Trip Software Detection
MCL
– Yellow
ASL
– Yellow Solid
Description
The Control Module monitors the Dynamic Brake (DB) resistor thermal condition by means of an
algorithm. When the software determines that the DB is at a critical level, it will cause the Error
17 and will shut the treadmill down until the DB cools to an appropriate level. The Machine
Control status light will go to yellow while the error is in effect. It will need to be manually reset
through the diagnostic menus.
Possible Causes
1. This is a user sourced issue
a. Runner at incline with a new deck and belt
b. Large runner at incline
Possible Remedies
1. Discuss normal operating modes with the club management. If the deck and belt are new,
this error will go probably go away after a few months of use.
1. Unplug all connections from the DB resistor and check switch for >10
Ω
. If greater than 10
Ω
replace the DB resistor.
2. Replace the MC.
Error 85
– No Dynamic Resistor Detected
MCL
– Yellow
ASL
– Yellow Solid
Description
The dynamic brake resistor (DBR) is designed to absorb the excessive current produced by the
drive motor running faster than it is being driven. When the Machine Controller boots up, it
checks for the resistor to be plugged in. If it does not detect the DBR an error 85 will be
displayed. It will only be displayed briefly when power is applied to the MC. The most probable
cause for this is the DBR not being plugged in, or it is open due to overheating or a broken
cable.
Possible Causes
1. DB Switch connector not plugged in
2. Connector pins are not seated correctly, or the wire is damaged/broken
3. DB Resistor faulty
