Fig. 68: Logic supply input of the timer

The voltage source to be used for supplying the timer is defined by the
other circuitry connected to X4.
Options:
• Supply by the unit's internal power generator (refer to page 366)
• Supply via an external power supply unit.
For this purpose, only a few jumpers have to be inserted/removed at X4.
For more information concerning the connections to X4, please refer
to section 7.2.9 starting on page 368.
Whereas voltage supply by the unit's internal voltage generator is
preferably used in stand-alone systems (e.g. suspended systems, be­
cause no additional 24 V
power supply units are the preferred solution in networked systems
(timer can be programmed by the line PC even if the welding network is
switched off).
Any external voltage sources used must be designed according to
"
the principles of "safety separation" in accordance with the Low-Vol­
tage Directive (2014/35/EU).
Special features for master slave applications
It is not necessary to turn on the master and the connected slaves si-
multaneously (logic supply at X4).
It should, however, be noted that the master signals "Ready" to the hig-
her−order control logic only if all connected slaves signal "Ready" to the
master (logic/power supply present, connections to the master establis-
hed, etc.).
For master slave operation, please also refer to section 7.2.9.1 on
"
page 371 and to section 13.3 starting on page 420.
