SUPPLY OF EL-POWER.
The electric circuit must only be connected to 12 volt DC. Connect directly to the tractor battery, to
avoid any loss of power. The fuse on the plus-leader must not be more than 10A.
See chap. 4.8 and 4.11.7 about connection and setting up of the machine.

DESCRIPTION OF THE SYSTEM.
All functions on the machine are operated from the remote control unit. It is a microprocessor
operated, programmable unit that controls the whole wrapping process. When e.g.
START (8)
is
pushed, the wrapping arm motor starts at ½ speed. After a preprogrammed time it switches over to
full speed. After approx. two revolutions it releases the film end, and switches over to ½ speed again
before it stops when number of programmed revolutions is obtained. (See also chapter 7.11).
The signals from the control unit are all the time sent to the magnet valves that shall be activated.
The exit clips in the control unit are numbered from 1-14.
