9.4.3 

Replacing the air flow sensor 

 

 

Warning 

When removing and mounting the air flow sensor, make sure that the sensor element is not damaged (i.e. does 
not break). Do not pull on the connection wires. 

After replacing an air flow sensor (new sensor), it is imperative to carry out a new initial reset (see Sec. 7.3.5). 

Remove connector 

A

 of the air flow sensor on the AMB 31. To remove an air flow sensor, gently press lock tab 

B

 towards the 

smoke sensor chamber. The air flow sensor can then be carefully pulled out of its holder by gripping tab 

C

 with thumb and in-

dex finger 

 

Attention: do not pull on the connection wires of the air flow sensor

. To install the new air flow sensor pro-

ceed in the reverse sequence. It is important to note the installation position (anti-twist safeguard) of the air flow sensor and 
that it is correctly seated in its holder. To do so, press the air flow sensor by its grip tabs 

C

 towards the housing base until the 

lock tab snaps over the air flow sensor 

 

Attention: do not press on the connection wires of the air flow sensor

.

9.4.4 

Replacing the AMB 31 Main Board 

To replace the AMB 31 Main Board, unplug all the plug-in terminals with installation wires. Likewise, all internal cable connec-
tions (ribbon cable connectors) must also carefully be unplugged. Once the 5 fastening screws of the AMB 31 have been re-
moved using a 

Torx T10 screwdriver

, the AMB 31 can be replaced. To install the new AMB 31, proceed in the reverse se-

quence. 

 

Warning 

When connecting the new AMB 31, take note of the correct assignment of the terminals and ribbon cable connec-
tors (see 

Fig. 5

). 

After replacing the AMB 31 it is imperative to carry out a new initial reset (see Sec. 7.3.5). Likewise, all customer-
specific configurations and project-specific settings from the “ASD PipeFlow” configuration software must be car-
ried out once again. To do so, proceed according to Sec. 7.3.1.
