PID controller 734 061

1. Prescribed use

The training panel is a component of the modular training panel system TPS 8.2 for automaticcontrol technology.

2. Location of use

Operate in dry rooms, which are suitable for experimenting with electrical operating equipment orinstallations.

3.4. Description/function

The PID controller contains:

– a P-action controller, an I-action element and a D-action element

– one inverting 2and two non-inverting 13 inputs, which lead to a differential amplifier at thecontroller input. The difference can be measured at socket bq.

– a control deviation display bqupstream from the controller

– a summing point – non-inverting 8and inverting 9 – at the output

The proportional controller gain Kp can be set coarsely using switch4in steps of x 0.1, x 1, x 10,x 100 and continuously from 0 to 10 using the control knob 7.

The correction time TN, measured in seconds, can be switched on using the I/OFF switch 5, whilea coarse setting in steps of x 0.01, x 0.1, x 1, x 10, x 100 is performed using switch 6 and a con-tinuous setting from 0.1 to 1 is made using control knob bp.

The rate time of the derivative-action element Tv, measured in seconds, can be switched on usingthe D/OFF switchbn, while the switchbmis used for a coarse setting in steps of x 0.01, x 0.1, x 1,x 10, x 100 and a continuous setting from 0.02 to 0.2 is made using control knob bo.

The setpoint or reference variable is fed to the non-inverting input 1, the actual value to the inver-ting input 2.

The control deviation display bq indicates whether the actual value is greater than or less than thesetpoint value.

The inverting 9 and non-inverting 8 input of the summing point at the controller output permit theforward feed of base loads, for example. Consequently the controller only needs to supply themanipulated variable for any deviation from this base load.

The integration capacitor can be short-circuited via the input bs:

Initial condition “ZERO”.

An external offset calibration can be carried out using socket br.
