3.4.7 Airflow
Use Select (Sel) to highlight the section to be edited and + and – to increase or decrease its value.
Change the airflow to increase or decrease the blower speed if the airflow is in fault. Refer to the pipe
calculations for calculated values.
With scanning units, all the pipes will be shown on
the display.
It is important to allow at least five minutes for the
airflow to settle after the blower speed has been
altered before accepting the airflow. Otherwise an
airflow fault can occur.
Always refer to the results of the pipe flow
calculation for the pipe installation to ensure the
correct blower speed is being used.
3.4.8 Unit/pipe text
The display receives the text from the detector unit.
Use Up, Down and Edit to select the text to be edited.
Then use Left, Right and Exit keys to select a character.
To change a character, use + and – to scroll through the symbols and alphabet in the following order:
!”£$%&’()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]_’abcdefghijklmnopqrstuvwxyz
After editing as required, press Exit to return to the Unit / Pipe Text display.
Press Accept, when the text has been modified, to send the text to the Unit.
Pressing Exit leaves the menu with the text unchanged (even after editting) if Accept has not been
pressed.
