023 Waiting for Vertical Plunger Up sensor bar switch to be on. .
Note: After the machine has extended the Vertical Plunger cylinder, the Vertical
Plunger Up magnet should be lined up with the Vertical Plunger sensor bar switch,
which turns the switch on. This is what the machine is waiting for.
The switch is located
at the top of the sensor bar at the white mark.
If the Vertical Plunger cylinder is fully extended,
- Check the air gap distance between the Vertical Plunger sensor bar switch and the
magnet. The distance should be a maximum of 3/8 inch (9 mm). If it is within the
suggested range then the sensor bar needs to be replaced.
If the Vertical Plunger cylinder is partially extended,
- Check that a bale or foreign object is not preventing the Vertical Plunger cylinder
from extending.
- Hydraulic power or hydraulic return has been disconnected or shut off from machine.
This circuit has a 2-position valve and cannot be partially extended unless power or
return has been disconnected or shut off.
If the Vertical Plunger cylinder is still retracted,
- Check that hydraulic power is still on to the machine and that return line is still
connected.
- Check that a bale or foreign object is not preventing the Vertical Plunger cylinder
from extending.
- Check that the directional valve is not stuck.
