Settling time T g
The time after a step change in the correcting variable defined by the intersections between the first inflection tangent and the abscissa, and the line parallel to the abscissa through the value in t
Output module
Output module for a signal transfer element, e.g. main hydraulic stage in a proportional valve.
Starting position; basic position
Position of the moving parts in a device at which the intended switching program starts under the action of the actuating forces. It is achieved via the starting prerequisites (CETOP RP 100).
Outlet pressure
Pressure measured at the outlet on a device (DIN 24 312).
Output device
Implementation of output elements and/or an output unit in a device (DIN 19 237).
Output unit
Function unit within a digital computer system with which the system outputs data - e.g. calculated results - to the exterior (EDIN 44 300 Part 5).
Failure rate
The relative number of failures referred to the related population. It comprises three phases (Figure A 26): Early failures : At the start of the operation of an installation (running-in period). Caus
On-stroke time of a pump
Time that a variable pump requires to adjust from zero to max. delivery flow (regulated). It depends on the adjustment mechanism, the pilot pressure and the adjustment travel, and also on the mass tha
Resolution
Increase in the input signal that is necessary to cause a change in the power output by the (continuously adjustable) valve at a specific signal level, expressed in % of the input signal. The resoluti
Opened control circuit
In some test procedures on control processes, the control circuit is "opened". As a result an input and an output are produced at the interface. The opened circuit can then be treated as a single cont
