short-circuited against ground (X5.1.14) so that any faults are acknowledged. The fault signalling

relay is reset. The input must remain closed for at least 2 line periods to perform acknowledgement.

After acknowledgement, the contactor must in turn be opened.

TERMINALS FUNCTION

X5.19-14 open controller operating

X5.19-14 closed* faults are reset

* for at least 2 line periods

TAB. 10 QUIT

If the QUIT contact is reopened the Controller will reassume operation with its preset operating

and control modes as well as its set point and limiting values.

4.7 SET POINT VALUE INPUTS

The set point inputs are described in chapter 2.2. SET POINT CONTROL CHARACTERISTIC.

4.8 ASM INPUT

This input (analogue voltage signal) is for measuring the total current signal of the external resis-

tance. For further details see chapter 6.4 ASM PROCEDURE.

4.9 dASM INPUT - dASM OUTPUT

The connections dASM input (X40) and dASM output (X41) are located at the bottom of Thyro-P

control device and have to be wired only if dASM function is used.

The wiring has to be done with patch cables (Ethernet CAT 5 8-pole) and only for a length of up to

100m between 2 power controllers.

4.10 ANALOG OUTPUTS

The electrical values for current, voltage and power at the load as well as the set point are recorded

by the Power Controller Thyro-P and may be optionally displayed using an external instrument or

logged using a graph recorder.

For connection of external instruments, there are three actual value outputs (terminals X5.2.32,

X5.2.33, X5.2.34, against X5.1.13). The selectable signal levels are 0-10 volts, 0-20mA, 4-20mA or -

setting different parameters at a maximum compliance voltage of 10V. In case of active ASM proce-

dure, only two of these three analog outputs are freely available (terminal X5.2.32, X5.2.34).

Each output has its own D/A converter. By setting parameters, it is possible to adjust the outputs

to stored-program controls, measuring instruments, etc.

For instance, the following values may be output:

• currents, voltages or power of the individual phases, total power

• minimum or maximum values

• set points

• phase angles

The signals of the analog outputs are updated in each line (VAR) or TAKT period. Actual values

always relate to the previous period. In operation mode VAR at a net period (e.g. 50Hz:20ms) and

in operation mode TAKT at T0 (e.g. 1 sec.). Different factors (e.g. set point variations, load varia-
