Before opening the terminal box cover, make sure to disconnect the
power cable from the mains!
With the push button T1, the spraying pump AND the conveyor belt can
be manually controlled.
If only the conveyor belt has to be driven, the plug of the spraying pump
shall then be disconnected. As long as the button is pressed, the conveyor
belt will keep moving.
For testing the spraying pump (likewise with push button T1), disturbance
would not be caused normally if the conveyor belt moves alongside.
If only the spraying pump has to be tested, the plug can be inserted into
the spare power socket or the plug from the engine of the conveyor belt
has to be removed (for this, the cover box must be removed from the
engine first).
