Operating Principle

When the fume extraction fan is running, it causes negative pressure inside
the fume cupboard. If the sash is lowered, the negative pressure becomes
more intense causing air to be drawn through the sash opening at an increased
velocity. Conversely, if the sash is raised, the negative pressure becomes less
intense and air velocity reduces.

If an opening is made in the wall of the fume cupboard, air will enter it at a
velocity determined by the same negative pressure that is drawing air into the
sash opening. By sensing the air velocity through an opening, we can determine
its level at the sash opening.

PLASTEC
hole in the cupboard and sending the air velocity measurement obtained to a
display on the fascia panel.

The air velocity level is displayed on the fascia either by LED illumination or
digital read-out. An audible alarm will also sound if the air velocity is too low.

Installation, Calibration & Alarm Test

INSTALLATION

1) Drill a Ø 23mm / 0.91" hole either in the top or side of the fume cupboard to allow sensor
positioning. Make sure sensor is not in a turbulent zone where the pressure can fluctuate but
where it can monitor stable changes in pressure. Attention should be paid to dead zones near
the top of the fume cupboard.

2) Proceed with wiring as seen on page “Contacts & Features”.

3) Position and secure monitor to service panel of the fume cupboard with the two self-tapping
screws supplied. Do not forget to position “O” ring seal into the moulded groove in the back of
the face plate.

CONTROLLER SET UP PROCEDURE

All monitors unless indicated otherwise are factory pre-calibrated at 0.5 m/s or 100 FPM. If you need a
different sensor calibration and/or displayed speed reading:

1) Make sure that the ventilation is on. Raise the fume cupoard to its test height e.g. 500mm/19.69".

Control with an anemometer that you have the required front air velocity.

2) Push
or
LED is on and the red LED is flashing indicating controller is in manual set up mode. For the

model without digital display (819700), please go directly to step 4.

3) For digital display model (819701). The display shows automatically 0.5 m/s / 100 FPM. If you
want another value, press “Reset” button at the back of the controller to change the required
speed display from 0.3 m/s / 59 FPM to 0.7 m/s / 138 FPM; that will be memorized as the set
point.

4) Wait for 15 seconds or so for air speed to stabilize.

5) To return to “AUTO” mode, push

the green LED is illuminated: new calibration (above or equal at 0.2 m/s) is accepted.

This is automatically done after 7 minutes in manual mode.

The buzzer beeps 10 times in case of incorrect calibration.

for more than 5 seconds, then release and push simultaneously

for Night Setback within the following 5 seconds. Buzzer sounds twice, the green

again until the buzzer beeps 3 times (about 3 seconds) and

for Standard

All updated information is stored in an internal memory which saves and holds

the data even in case of power cut.

VELOCITY TYPE

To change Digital readout from/to m/s to FPM:

Press simultaneously the following buttons:

until buzzer sounds (about 5 seconds).

DISPLAY MESSAGES

The display will show “HI” for an airflow superior to 1 m/s / 196 FPM and “LO” for an airflow inferior to

0.20 m/s / 40 FPM.

In case of faulty, improper or absent sensor, the display will show “PB”.

FACTORY DATA RESET

Press “Reset” (at the back of the controller) for 15 seconds. Buzzer sounds 5 times.

When using this feature, you restore factory default settings: set point and display at 0.5 m/s / 100
FPM, 7V output to the inverter and all relays and LEDs deactivated.

This operation should be imperatively done in “Auto” mode.

TEST MODE

Test mode is to confirm that all functions are operational. To access test mode, follow this procedure:

1) Press simultaneously following buttons:

* Buzzer sounds twice

2) Press the 3 buttons alternately.

* Buzzer sounds 10 times if malfunction

In case of faulty sensor, the display will show “PB”.

* Buzzer sounds 3 times indicating normal operating mode

Maintenance, Troubleshooting & Warranty

MAINTENANCE

Front plate and stickers of airflow monitor may be cleaned with mild soap and water on a damp
cloth to remove finger marks, oils and residue. Do not use abrasives. Do not allow liquids to enter
the plastic casing. Dry the monitor thoroughly after cleaning.

TROUBLESHOOTING

PROBLEM CHECK

No indicators Power supply may not be plugged into AC supply.

Improper alarm setpoint Airflow sensor is factory precalibrated at 0.5 m/s or 100 FPM.

Field reading may be different if sensor is not properly located
or hood design affects stable airflow. If intended air speed is
different than 0.5 m/s / 100 FPM or if actual anemometer reading
is different, follow Controller Set Up Procedure on page 6.

WARRANTY

PLASTEC® Ventilation, Inc. warrants its equipment, products and parts, to be free from defects in
workmanship and material under normal use and service for one year after delivery to the first
user. Product must be returned to point of purchase, with dated bill of sale, within one year of
purchase. If factory return is required, please contact distributor first.
