Pressure X2

For cable type and maximum cable length, please refer to the table “Cables”, see sec-

tion 5.
The connection between PSI 6XXX.190 W1 and the pressure control valve consists of a
shielded cable. The shield is connected to X2/5 and the shield ground at the pressure
control valve.

Pressure output

Depending on the programming and timer type used, an output signal is provided at the
pressure output if the program number has been selected:

-

analog pressure output, voltage from 0 V to +10 VDC, max. 20 mA

The pressure output is immediately driven when the program has been selected exter-
nally.

Pressure input

A +24 signal (20 mA) at input X2/4 serves as an input to the WT by which an external force
and comparison device signals that the specified pressure/force value has been reached
at the electrodes. This 

<Pressure input>

 signal is linked by a logic AND with the

 <Moni-

toring contact>

 in the WT and acts together with it as a condition for Start of the SQZ.

When operated without this external force measuring and comparison device (without
pressure control valve), input X2/4 has to be permanently supplied with a +24V signal,
and terminal X2/2 has to be connected to the 0 V potential of the 24 VDC supply.

The logic condition of the pressure input can be checked using 

Operation - Diagnostics

I/Os- Inputs (I08)

.

While the PSI 6XXX.190 W1 waits for the pressure input, selecting 

Operation - Diagnos-

tics - Timer

 will show Status: 

Waiting for pressure contact

 in the Current sequence - In-

terval: SQZ display field.
