36 I DELLMECO I AODD DIAPHRAGM PUMPS
b) Option code SC5, SC6
Differently from the optional equipment codes SC1-SC3, the strokes of the pump are registered pneumatically on
the codes SC5 and SC6. The pressure transmitter registers the changes in pressure within the air chamber behind
one of the diaphragms and it converts the pneumatic impulse into an electrical signal.
The pneumatic stroke counting system is available in two types:
•
SC 5
consist of:
-
pressure transmitter 1-10 bar
-
socket with cable 2,5 m
-
adaptor elbo
w NPT ¼
(or adaptor straight M5 only for DM 15/30 pump)
-
hose DN 4/6; 2,5m
•
SC 6
consist of:
-
SC 5 plus stroke counter
For assembly, screw the adaptor straight into the pressure transmitter (connection P1) and adaptor elbow into
the additional air connection of the pump (it is possible that the adaptors are already installed). The position of the air
inlet varies depending in the pump type and the pump size (see comments below). Link up both adaptors with the
hose. Connect the socket to the electrical connection plug of the pressure transmitter and the cable to existing
registering devices (Code SC5) resp. to the enclosed stroke counter (Code SC6). Technical data, connection
schemes and further details can be found in the technical documentation delivered by the manufacturers of the
pressure transmitter and the stroke counter.
The air inlet for the pneumatic stroke counting system must not be confused with the actual air inlet of the pump.
Therefore, you will find some advises adapted to the pump type and the pump size.
