Another alternative is to switch off and switch on the power supply to the Drive unit.
Afterwards, you can restart the motor with one of the start buttons.
NOTE!
If the overload protection is activated when the suction trolley is connected to
the current collector SLX3, the overload protection is not reset until you have manually
moved the suction trolley away from the current collector or pulled down the hose so that
SLX is activated.
When the suction trolley is in disconnection position and the overload protection triggers,
it is likely that a mechanical fault has occurred. The operator must pay attention to any
faults in the driving slot/current collector.
The suction trolley jams in an object and the driving slot disengages from
the stop ball
If the hose/suction trolley jams for some reason then the driving slot will disengage from
the stop ball and the suction trolley return is interrupted. The drive motor will continue
to run until the stop ball reaches the limit position SL4 when the motor is stopped.
When you have rectified the problem that caused the disconnection you can restart the
drive motor with a start button. The driving slot is designed so that it can reconnect a
disconnected suction trolley on the stop ball.
NOTE!
Other malfunctions, see chapter ‘9 Troubleshooting’ or contact a service
technician.
