Operation by the user
If a valid Purging program has been set on the Purging unit, the unit operates in the automatic mode
and the status LED indicates the current condition.
In this case the Purging processes will be carried out automatically. If additional Purging processes
are needed, you can carry them out by pressing the external push-button „Manual activation",
provided that this feature has been prepared by the installer of the system. In this case, the com-
pressed air will be blown into the pipe network for as long as the push-button is being pressed, but
the maximum duration for one press of the push-button is limited to 2 minutes.
3.3
Operation by the installer
If a valid Purging program (Purging program „1" ... „C") has been set on the Purging unit, addi-
tional Purging processes can be started manually.
A manual Purging process can be started by briefly pressing the button TA1; depending on the Pur-
ging program that has been set with the rotary switch „Purging program" SW1, this will carry out a
long or short Purging process.
The button TA1 will only be accessible after removing the cover (see Fig. 4 on page 20).

Chapter 3 • Displaying of the operating conditions and operation
Condition of the control board / response time / effect / removal
Condition: A short circuit on the connection line to the fault contact of the aspirat-
ing smoke detector has been detected.
Response time: Immediately
Effect: If the Purging unit is synchronised by an external timer and the short circuit
exists for approx. 60 seconds, the internal clock will be synchronised to 00:00.
If the short circuit exists for less than 50 seconds, this will be indicated by the
status LED, but apart from that it will not be evaluated. If the short circuit exists
for more than 70 seconds, this will be evaluated as fault, the condition of the status
LED will change to illuminating yellow.
Removal: If the time has not been synchronised, the connection line must be
checked.
Condition: There is a fault.
Response time: Immediately
Effect: Maybe the aspirating smoke detector is partly or completely out of order
and must be checked.
Removal: If an air flow fault of the aspirating smoke detector exists, further
manual Purging processes should be carried out in order to remove the clogging
(see on page 31 in Chapter 9.3: „Location of the display and operating elements
and terminals on the control board of the Automatic Purging Unit F-BO-AFE70").
If there is another fault, it must be removed on the aspirating smoke detector.
If there is no fault of the aspirating smoke detector, the connection line must be
checked for freedom from faults.
