MOTOR CURRENT TEST
The test verifies that the system is operating under normal motor current levels. A contributing
factor is excess motor current is proper maintenance. As the friction between the running deck
and belt increases so does motor current. Listed below are typical current levels at specific
speeds.
To activate motor current test turn system OFF and then ON. While all LED'S are lit depress
<Stop> and <Speed -> buttons simultaneously. Using the <Speed> buttons select speed as listed
below to verify motor current values. If motor current value varies by more than 20% refer to
the maintenance section of the manual. If after maintenance is performed motor current value
continues at 20% above listed value, contact Biodex Technical Support for assistance.
