Installation
Optional added features
The DL250 can be configured to suit customer specification.
These optional extras would be discussed, arranged and
installed prior to delivery.
(
If unsure what features your DL250 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 24V signal.
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 the Black & Red cores of the
signal cable (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 between 12 &
24VDC. Only voltages within this range should be
connected. Voltages connected outside of this range may
cause irreversible damage to the internal control PCB.
Red cable = V+
Black cable = V-
When the extractor is provided with the correct DC voltage
the motor will start and maintain the flow rate. 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 internal motor access panel (see below 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.
Footswitch
A footswitch is available for the DentalPRO DL250. The
switch is plugged into the jack port at the rear of the unit.
The unit can be powered on and off via this foot operated
switch.
Angled Lid
The DentalPRO DL250 is available with a 90 degree spigot
lid should your installation require a horizontal air inlet.
