Ramp generator
Electronic functional group to produce ramps. Its effect is based on the fact that an electrical condenser (C) is charged (and discharged) with a delay ( Figure R 10 ), resulting in a general voltage
Process-dependent workflow control
Workflow control with step enabling conditions that are only dependent on signals from the controlled system (process) (DIN 19 237). The process-dependent workflow control – previously known as "seque
Program module
General : A part of a program which can be delimited in terms of its allotted task or structure. A control : Consequence associated with control instructions for a self-contained application-based fun
Switching element
The part of a valve , which ensures the desired function through its movements.
Non-linear control system
whereby the control algorithm is associated with non-linear behaviour, i.e. the input and output for the controller are linked to each other by a non-linear characteristic curve or function.
Characteristic curve
General : Graphically represented mutual dependency between two operating variables, often with a constant third being used as the parameter. Example: In Figure D79, the flow rate Q is applied to a co
Filter size
The required filter size is based on the permissible flow resistance of the oil filter at the nominal flow rate. The selection of the filter size is affected by: The selected filtration grade , The fl
Incremental encoder
Adding together of increments (e.g. based on distances of 0.01 mm) in a counter outside of the actual measuring device . Increments are delivered in the form of electrical pulses and are added togethe
Pre-load valve
Pressure valve , which maintains a pressure before its inlet that is normally adjustable using a spring (e.g. to maintain a dynamic pressure).
Secondary pressure
Pressure in an auxiliary circuit fed by the main circuit of a system, in which the pressure is lower than the primary pressure . This is generally achieved using a pressure-reducing valve .
