Operation

This safety feature serves to protect the user should they lose their balance or in an
emergency. The plastic clip is to be fixed to the waistband when the treadmill is
used. When the magnet (trigger) is removed, the drive motor is switched off and
the running surface stops. The running surface cannot stop immediately when run-
ning at high speeds, since the weight of the running surface needs to be decelerat-
ed and there is excess residual energy due to the fast movement.
The safety magnet can also be used to stop the treadmill. To prevent the use of the
treadmill, for example when not supervised; the safety magnet with pull cord can
be stored in a safe place. Then the treadmill cannot be put into operation.
7.2.3 Belt Drive Current Limiter
The treadmills have a current limiting function to reduce power consumption and to
increase safety. The main function is a current limit timeout. If the running surface
belt remains stationary for more than 10 seconds (remains in the current limit), the
motor drive is switched off and the belt can be moved manually (turns freely). This
function is very helpful if something gets caught in the tread belt. In this way the
treadmill can be stopped.
If the running surface belt is in current limit mode, the treadmill must be to be
switched off with the main switch for at least 60 seconds so that it can be reset.
Only then can it be switched on again.
7.2.4 Low Leakage Current
The requirement for low leakage current is important for medical clinics, physical
therapy facilities and hospitals.
The treadmill functions are designed so that the power plug and input power trans-
former are subjected to low leakage current. With an input power transformer with
low leakage current, the leakage treadmill current can be reduced to less than 100
micro-amps (uA).
