Parameterisation of the Purging unit
9.5.1
Setting the Purging program
The desired Purging program is set by means of the rotary switch „Purging program" SW1 (see on
page 36 in Table 8 and on page 39 in Fig. 16).
In switch positions „1" through „C" of rotary switch SW1, the selected Purging program will be
carried out as soon as the aspirating smoke detector reports a „fault" (e.g., the air flow through
the sampling pipework is impeded by contamination), independent of the time.
In the Automatic Purging Unit F-BO-AFE70, two Purging processes with different duration and
number of impulses can be selected:
the „short" Purging process carries out 3 impulses with a duration of 3 seconds each and with
2 pauses of 3 seconds in between, i.e., with a total duration of approx. 15 seconds, and is inten-
ded for normal contamination,
the „long" Purging process carries out 5 impulses with a duration of 5 seconds each and with
4 pauses of 5 seconds in between, i.e., with a total duration of approx. 45 seconds, and is inten-
ded for persistent contamination.
Please note that more compressed air is needed for the long Purging process.
SW1 Purging program
0
Setting the time – manual activation not possible
1
Once a day at 10:00 and in case of a fault, always with long Purging process
2
Twice a day at 09:00 and 14:00 and in case of a fault, always with long Purging process
3
Three times a day at 06:00, 12:00 and 18:00 and in case of a fault, always with long Pur-
ging process
4
Four times a day at 5:00, 10:00, 15:00 and 20:00 and in case of a fault, always with long
Purging process
5
Six times a day at 4:00, 8:00, 12:00, 16:00, 20:00 and 00:00 and in case of a fault, always
with long Purging process
6
Long Purging process in the event of a fault of the evaluation unit of the aspirating smoke
detector
This program is also to be used if the Purging processes are only started by a push-button,
or if the Purging unit operates as „slave".
7
Once a day at 10:00 and in case of a fault, always with short Purging process
8
Twice a day at 09:00 and 14:00 and in case of a fault, always with short Purging process
9
Three times a day at 06:00, 12:00 and 18:00 and in case of a fault, always with short Pur-
ging process
A
Four times a day at 5:00, 10:00, 15:00 and 20:00 and in case of a fault, always with short
Purging process
B
Six times a day at 4:00, 8:00, 12:00, 16:00, 20:00 and 00:00 and in case of a fault, always
with short Purging process
C
Short Purging process in the event of a fault
D
No Purging program; a fault will be transmitted without delay, manual activation is not
possible
E
No Purging program; a fault will be transmitted without delay, manual activation is not
possible
F
Setting the device number - manual activation not possible
