An NC control without a positional feed back system. See also closed loop
A control system without feedback.
A mode of computer operation in which fuel delevery calculations are based primarily on preprogrammed values, not Oxygen sensor input 2. The Oxygen sensor value is not considered when in Open Loop
Any type of circuit, electrical or neural, in which there is no feedback to help regulate the performance of the circuit
a loop established between a water source and a discharge area in which the water is collected and pumped to a GWHP then discharged to its original source or to another location
refers to those times when ECU ignores the feedback from the oxygen sensor.
Control system with no sensory feedback.
A motion system which does not utilize a feedback element.
system operating without feedback, or with only partial feedback. See closed loop system.
Refers to a motion control system where no external sensors are used to provide position or velocity correction signals.
Control system using preset values in the computer to operate engine. See also: CLOSED LOOP.
A system in which there is no feedback. Motor motion is expected to faithfully follow the input command. Stepping motor systems are an example of open-loop control.
(circuit) Refers to operation of an amplifier without feedback, as opposed to closed loop which is operation with feedback.
Controller in manual mode. See Mode.
A motion system that does not use a feedback device for position and velocity verification or control.
An auxiliary, fabricated of orthodontic wire, prepared such that the two 'legs' of the passive loop are nowhere in contact with one another.
In engines with a computer and oxygen-sensor control system, a mode of operation during which the computer ignores the signal from the oxygen sensor, typically before the engine reaches normal operating temperature.
(n) A set of edges in a CAD model that does not connect end to end, creating a closed loop. Solid modelers differ as to whether open loops can be used as profiles for feature generation. Open loops cannot be used to define faces on a solid model.
A system in which there is no self-correcting action for errors, as there is in a closed-loop system.
refers to an RFID system in which tags must be compatible at different steps in the supply chain. Because tags typically are not reused, they are less expensive than in closed-loop applications. Open-loop systems are primarily used in retail and distribution environments.
