PUF+ CONNECTIONS
The descriptions of the various connections to the PUF+ control unit are described
below.
“Motor”
The “Motor” power connection supplies power to the motor being controlled by the
PUF+. Both Brush-Type and Brushless-Type motor are supported, but only one may be used
at a time. The PUF+ will come configured to match the motor type ordered. THE MOTOR
USED WITH THE PUF+ MUST MATCH THE AC POWER BEING SUPPLIED TO
THE PUF+. WHILE THE PUF+ CONTROLS THE MOTOR SPEED THROUGH THE
EMBEDDED ELECTRONICS, IT CAN NOT CHANGE THE OPERATING VOLTAGE
OR THE FREQUENCY OF THE INCOMING POWER THAT IS SUPPLIED TO THE
MOTOR.
“Power”
The “Power” connection supplies power to the PUF+. It should be connected to the
AC power line. Operation at both 120 Volts AC and 240 Volts AC are supported. The
system is designed to operate at either 50 or 60 Hz without the need to change the
configuration of the unit. However, a jumper inside the PUF+ determines the voltage on
which the unit operates. DO NOT APPLY 240-VOLT POWER TO THE PUF+ WHILE
THE UNIT IS CONFIGURED FOR 120-VOLT OPERATION. THIS WILL DAMAGE
THE UNIT. APPLYING 120-VOLT POWER TO THE PUF+ WHILE THE UNITS IS
CONFIGURED FOR 240-VOLT OPERATION SHOULD NOT DAMAGE THE UNIT,
BUT IS NOT RECOMMENDED OR SUPPORTED.

“AutoCal” Pressure
The “AutoCal” pressure port is used to make the Pcal measurement. It should be
connected to the calibrator during the AutoCal procedure.
“Ambient” Pressure
The “Ambient” pressure port is used to make the Pamb measurement. It should be
left open to atmosphere so that it properly senses the ambient pressure.
“Orifice +” Pressure
The “Orifice +” pressure port is used to make one half of the Pdif measurement. It
should be connected to the upstream port of the orifice (upper most port). Both “Orifice +”
and “Orifice –” must be connected to the orifice for proper flow measurement.
“Orifice –” Pressure
The “Orifice –” pressure port is used to make one half of the Pdif measurement. It
should be connected to the downstream port of the orifice (lower most port). Both “Orifice
+” and “Orifice –” must be connected to the orifice for proper flow measurement.
“Ambient” Temperature
The Ambient Temperature thermocouple port is used to make the Tamb
measurement. A Type K thermocouple must be used. The sensing tip of the thermocouple
should be located so that it receives air flow while the unit is sampling and is always shield
from the sun. By locating the sensor in this manner it can be used to monitor two items of
importance. Most importantly, this will allow for the accurate measurement of the ambient
temperature while the unit is sampling. In addition, when the unit is not sampling this allows
the temperature of the filter to be approximated. This can be of importance when sampling
for compounds that may changes phases (i.e. from solid to gas) due to changes in
temperature. Below, is a picture showing a suitable location for the thermocouple. Note the
thermocouple tip should be located so that it does not come into direct contact with any
surface.
