TROUBLESHOOTING-TELESCOPIC SYSTEM
PACKING REFUSE-CONTINUED
HYDRAULIC SEQUENCE
While the carrier and packer panels are moving up,
compacting refuse against the pushout panel, pressure
is building in the case end of the carrier cylinders. This
pressure is also building in a pilot line from the carrier
valve section to the FCV (Front Control Valve) pushout
section. When this pressure reaches 1800 PSI (124
BAR), a relief (resistance) cartridge opens in the FCV
(Front Control Valve) pushout section, allowing some
case end pressure from the telescopic pushout cylin-
der to return to tank. This allows the pushout panel to
come forward slightly.
