Commissioning and function test
This chapter is devoted mainly to providing general information and showing a recommended
sequence aimed at facilitating rapid and successful commissioning of an Automatic Purging
Unit F-BO-AFE70.
The major prerequisites for successful commissioning are the expert installation and the correct
connection of the Purging unit.
Before and during commissioning, go through the following checklist point by point in order to
make the commissioning smooth and safe:
Pay attention to the danger notices given on page 3.
In order to exclude an undesired activation of the Purging unit completely, you have to reli-
ably turn off or interrupt the compressed-air supply to the Purging unit prior to commis-
sioning and make sure that it can not be turned on or connected by mistake.
Before carrying out the first Purging processes, make sure that all connections in the sys-
tem are flawless and the glue of the joints has sufficiently hardened. Make absolutely sure
that both the supply line of the compressed air as well as the supply voltage are reliably
turned off or disconnected and that they can not be turned on or connected again by mis-
take.
Make sure that, during the first Purging processes, no persons are present in the area of the
pipe network and especially in the area of the Purging openings and the opening of the
check valve; solid bodies and liquids that are driven by the compressed air can escape with
high velocity and can cause injuries!
Take care that fingers, other parts of the body, and objects never get into the open pipe con-
nection opening. During the Purging process, the valve that is integrated into the Automatic
Purging Unit F-BO-AFE70 is closed with high velocity and great force. As a result, parts of
the body or objects, which are in the valve body, can be seriously injured or even severed or
destroyed respectively! In addition, the Purging unit can be severely damaged or destroyed
as a result.
Integration into the pipe network:
Has the Purging unit been integrated into the pipe network at the correct position and has the
glue of the joints hardened completely?
Have the 25mm push-in fittings been connected to the valve body and are these connections
firm and airtight?
You must never use any glue for the connections of the sampling pipes on the Purging unit and
on the aspirating smoke detector.
Opening the pipe connection to the aspirating smoke detector:
Open the pipe connection between the aspirating smoke detector and the Purging unit and make
sure that no contamination can get into the aspiration opening of the aspirating smoke detector.
Cabling:
Is the cabling both to the fire detection control panel and to the evaluation unit of the aspirating
smoke detector correct and complete?
Make sure that no fault of the aspirating smoke detector exists on the fault input of the Purging
unit. In order to make this absolutely sure, a 5.6kOhm resistor, instead of the aspirating smoke
detector, can be temporarily connected to the fault input for the time of commissioning.
Connection of the supply voltage:
Make sure that the compressed-air supply to the Purging unit has been turned off.
Set the rotary switch „Purging program" SW1 to „0", which means that no Purging program is
set.
Connect the supply voltage – the „status LED" of the Purging unit must be flashing green.
Set the program switch SW1 to position 6 (which means that only faults of the aspirating smoke
detector will be evaluated, but Purging processes according to the internal clock will not be car-
ried out).
