AFA1000/2 MK2 Airflow Monitor
Installation & Operating Manual
6.1 Configuration
The Airflow Monitor can be configured via a Laptop or PC using a variety of ‘set up’ programs
each designed for a particular application with a combination of inputs, outputs and push
buttons.
This configuration can be changed via the key pad using the menu system if required or
re-configured by re-connection of the laptop or PC.
This allows the fume cupboard manufacturer to stock standard units and configure the monitors
to suit the application.
The configuration of the various functions and the calibration of the monitor face velocity display
is menu driven. Access to the menu will be via password (4 digit number) and will be two level.
The first level will be for calibration of the unit and the second level will be for ‘engineers’ to set
up the configuration of the alarm.
NOTE: If you enter the Calibration or Configure Menu by accident:
Press the + & - buttons at the same time to escape back to the main menu.
The menus and sub–menus are in ‘plain language’ and incorporate brief instructions where
appropriate.

operation document.
6.2 Start Up
When unit is powered up the following sequence of events occur:
1.
The 12V DC power is applied to the airflow sensor and a delay on timer is initiated.
2.
The alarm then performs a self test on the display and all indicators etc ( approx 5 sec )
3.
At the end of the delay period the unit performs one of two options:
a.
If the monitor calibration has been previously completed – the unit goes to normal
operating mode (Run)
b.
If the unit has not been calibrated the unit displays ‘Unit requires Set up -- press
Enter to access Set up menu ’ The set up menu allows calibration or configuration via the
password protection
Note -
If the unit has been set with a Fan Stop / Start pushbutton the monitor can be set to
Run mode before it is calibrated to allow the Fan to be Started. To Enter the menu from the Run
screen press and hold the ENTER button for 5 seconds or until the main menu appears.
During the set-up all alarms and output relays are inhibited.
