Installation
Optional added features
The Base DWX can be configured to suit customer
specification. These optional extras would be discussed,
arranged and installed prior to delivery.
(
If unsure what features your Base DWX is equipped with
please contact the seller with the unit serial number,
(Refer to section 2 for location) who will be able to advise
what specification has been supplied.
Remote Stop/Start feature
Enables the extraction unit to be remotely turned On / Off
via an external signal.
This feature can be configured in 2 ways
•
DC Voltage input – Range 24VDC
•
Override – Stop / Start feature switched off
Note: Care must be taken to ensure that the system is
correctly wired in order for the extraction unit to function
correctly.
DC Voltage input
This configuration requires pins 1( +) & 6 (-) of the 9way
connector (Refer to section
1 for location) to be connected
to a known and tested DC power supply, in order to start the
extractor.
The operating voltage for this signal is 24VDC. Voltages
connected outside of this may cause irreversible damage to
the internal relay.
Pin 1 = V+
Pin 6= V-
When the extractor is provided with the correct DC voltage
the motor will start and maintain the set flow rate (Refer to
section
5 for how to set the flow) when the DC voltage is
removed the motor will slow down and come to a stop.
The extractor will need to be turned on (See section
5 for
turning the extractor on) in order for this feature to operate.
Override
Enables the extractor to operate fully with or without either
DC voltage input or the Volt free input.
The override feature can be toggled On / Off by a switch
mounted on the front panel (see section 1 for switch
location)
Switch in “On” position
In this position the extractor will require a start signal (either
Voltage input or Volt free, depending on the requested
specification) to enable the motor within the extraction unit.
Switch in “Off” position
In this position the extractor motor will run without the
requirement for an external start signal. This feature is
useful for engineers carrying out works/ tests on the
extractor without the need for the auxiliary signal being
present.
Compressor (Optional)
With this option an on board compressor will be fitted to the
extraction unit. The compressor is mounted internally with
the outlet mounted on the rear of the unit (see section 1 for
location)
The compressor can be configured to 115V or 230V by an
internal voltage selector switch. As standard the
compressors are configured to 230V. (Isolate the mains
supply before moving the rear panel of the extractor)
The compressed air outlet hose should have a water trap
fitted, this must always be fitted at the milling machine
end.
