Needle Valve A valve to lower the backstay manually when the lifting lever is not
available.
Normal State A term used with switches or relays. Their "normal state" means that
they are not under any control of stress,temperature, pressure or
electricity.
Ohm (Ω) A resistance unit. The resistance will be such that one volt shall push
one ampere of current through it only.
Timely The time it takes for a current to flow through a transistor.
Open Circuit A connection or component of a circuit without continuity.
Hole A limited passage in a hydraulic circuit, including a limited flow or
pressure generation in a given chamber
(e.g. a small bore).
Top Cover A overhead frame structure which protects the operator from falling
objects
Overload A condition that the existing voltage or current is greater than the
capacity of a given circuit or component.
Piston Rod A part that push oil into the cylinder chamber
Suffocated The part of an electric brake in which the current generated is directed
back to the armature.
Port An input or output point on a hydraulic element
Power Socket A connecting socket that installed on the forklift.
Pressure a fluid force as per unit area
Proximity Detector
A sensor which can detect the presence of objects nearby without any
physical contact.
Pump Controller
Unit
A control device for a hydraulic motor, which includes an inverter and a
logic circuit.
Safety Valve A valve that limits the pressure of the hydraulic system by releasing
excess oil
Resistance A component made of a material with a specific current impedance.
Return Filter A filter to collect contaminants in oil returned to a hydraulic tank
Rotor A part of rotating motor.
Outline A bar chart of an electrical or electronic component that uses symbols to
show the individual components as well as how the wires and
connectors work electrically
Serial Port A port that communicates one-to-one with the controller.
Service Brake A pair of brakes built into the drive shaft to enable the vehicle when the
operator applies the pedal
for stationary
Short Circuit An unwanted electrical connection between two or more components.
Side Shifter An accessory that moves the fork and its load to the left and right
Socket The male contact of the connector which slides over the male contact of
the other connector (pin).
