PSI 6XXX.190 W1
7-13
1070 080 086-101 (01.01) GB
Configuration D
If the external 24 V DC supply to PSI 6XXX.190 W1 cannot be provided by one power
supply unit for reasons of potential separation between the timer logic and the I/O supply,
the power supply has to be designed in accordance with configuration D. Several jump-
ers have to be positioned to enable this configuration.
The power supply to the timer is thus independent of the welding network (external power
supply).
In configuration D, the external power supply unit
[1]
must satisfy the following require-
ments:
-
maximum ripple <5%, tolerance -15% / + 20%.
-
Making current: approx. 0.2 A, duration approx. 10 ms, plus the current of
the inputs and outputs.
-
continuous current: approx. 0.1 A, plus the current of the inputs and outputs.
In configuration D, the external power supply unit
[2]
must satisfy the following require-
ments:
-
maximum ripple <5%, tolerance -15% / + 20%.
-
Making current: approx. 2.0 A, duration approx. 10 ms, plus the current of
the external unit connected to X5.
-
continuous current: approx. 1.5 A, plus the current of the external unit con-
nected to X5.
NOTE
For determining the power supply rating, sum up the individual loads required.
Functions:
-
When the welding network is switched off, no interfaces will be interrupted:
-
communication via the I/O interfaces is possible
-
communication between the timer and the programming terminal, e.g. pro-
gramming and visualization, is possible.
-
Preferably used with networked systems.
-
The
Stop function
is ensured by means of a
floating contact
which is to be con-
nected to terminals X4/3 and X4/4.
-
Opening the stop contact will interrupt:
-
the
firing
-
the
power supply
to the
parallel inputs and outputs
-
the
power supply
to the external unit.
