26 DUSTOMAT 21-67 H 09302-52-00
12. Optional equipment
12.1 Start-up with potential-free contact
Optionally, the DUSTOMAT can be equipped with start-up through an external
potential-free contact. This means there can be a coupling between the
DUSTOMAT’s fan and a processing machine connected to it. In this case, the
processing machine starts and stops the fan.
The grey rotary switch on the switch box must be set to “AUTO” for this operating
mode. In the “HAND” setting, the DUSTOMAT is operated as previously described.
Pins 1 and 2 of the external, potential-free contact are connected to the plug
(packaged with the device). Pin 3 is
reserved for the neutral wire. This is
needed only when using special ESTA
accessories. Connect the potential
equalization to the PIN with the earthing
(ground) indicator. (Please follow the
enclosed switching documentation!)
All electrical installations necessary to
starting up the dust extractor, as well as
electrical modifications and installation
work to the processing machines, must be
done only by an electrical specialist or a
person trained for the job. As soon as the
main switch is set to “ON”, the contacts to the dust extractor’s black socket carry
230 volts!
When the processing machines are connected, the dust extractor can start
running by itself at any time!
When maintenance work is being done to the dust extractor, therefore, the
control cable to the control box must be disconnected, and the main switch must
be set to “0” and secured with a padlock against unintentional start-up! Unplug the
dust extractor from the electrical grid.
When maintenance work is being done to the connected processing machines
and devices or control units, the control cable to the dust extractor must be
disconnected. All main switches must be set to
“0” and secured, if possible, with a
padlock against unintentional start-up! Additionally, all electrical plugs must be
pulled. If this is not possible, take appropriate measures to ensure that all
machines are free of current. This applies to all machines connected to the
system.
