The connection housing is designed as the common
platform for all external connections to the applicator.
The connections for material supply (AW) and return
(AV) are placed in the upper connection piece.
The connections are internal 3/8" BSP. One or two con-
nectors for electrical signals are mounted in the bracket
attached to the base module.
The base module may also include a PT100 tempera-
ture sensor (AK) in the material inlet and a pressure
transducer (AF) in the material return channel. When
spraying there is no return flow, the pressure then in the
return line is equal to the pressure just before the nozzle
head.
These sensors and the solenoid valves are connected
to terminals on the pin connector (AM). Note that differ-
ent pin connectors exist depending on applicator ver-
sions i.e. 5 or 18 pins.
