1.1.3 Control cards
The control card converts the inputs from the user and the sensors into outputs to the motor solenoid and the
valves which accomplish the desired motion. The Z3N can be equipped with one of two models of control cards,
dependingonmarketandrequiredfunctionality.TherstcontrolcardistheZePRO1controlcardwhichisanad-
vanced processor based circuit card. The second is the simpler TLC-B1 card which is based on solid state relay
technology.

1.1.4 Auto tilt
A tail lift equipped with auto tilt functionality automatically tilts the platform down when the platform reaches
the ground and then tilts is back up to horizontal without any additional input from the user other than keeping
the lower/raise button pressed throughtout the motion. The Z3N can be equipped with an electrical auto tilt system
based on a digital auto tilt sensor located on the platform.
Whether the tail lift is equipped with auto tilt functionality or not cannot be determined by reading the information
onthetypesign.Insteadthetypeandnumberofsensorsinstalledontheplatformshouldbechecked. Ifthereis
onlyaball-basedanglesensorinstalled,thetailliftisn'tequippedwithautotiltfunctionality.Ifthereisbotha
ball-based and a liquid-based angle sensor installed, the tail lift is equipped with digital auto tilt.
