ΙΙΙΙΙ controller 734 04

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 Ι controller operates non-inverting via inputs 1and outputs 2. The “off” input 3leads to thereset switch of the integral-action capacitor and is required when operating with the test functiongenerator 734 40. This ensures that the starting condition Ua = 0 is restored after each recordingperiod.

Switch S2 4is connected in parallel to the automatic reset switch. The integral-action capacitorcan only be charged in position “ON”.

The integral-action coefficient KI (unit: second s–1) can be roughly adjusted in steps of x 0.1; x 1;x 10 with switch 6and fine, continuous adjustment is made with potentiometer 5from 1 to 10:

If the circuit is overdriven, the “ OVER“ LED 7lights up. This condition can be remedied by dischar-ging the integral-action capacitor: switch S2 4to “off”.

The integral action capacitor can be short-circuit via the input 3:

initial condition “NULL”.

5. Putting into operation and operating

The device is inserted into the panel frames and connected to a suitable ±15 V power supplydevice, e.g. cat. no. 726 86.

6. Technical data

Power supply: ±15 V

Input and output signal range: ±10 V
