Control connections and configuration
Application: Water pumping with automatic pressure control
This setup is for a typical centrifical pump application that requires water pressure control using a water
pressure transducer and PID controller function provided by the MSC-3. Prior to commissioning, you
will need to know the type of water pressure transducer signal that is to be used (0-10V,4-20mA etc).
Procedure
STEP 1
Complete the power wiring according to the instructions on pages 9 to 18
STEP 2 Connect the control wiring as shown.
CAUTION
Do not connect the wire
to terminal 6 yet.
The terminal configuration
should not be changed
while the MSC-3 is
enabled.

STEP 3
Connect the signal wiring from the water pressure transducer as shown. Consult the
pressure transducer manufacturer’s literature for power supply requirements of the
transducer.
Go to the G00 INPUT/OUTPUT menu and select G10 AI(32,34). Set G100 for the type of
transducer signal to be used (mA or voltage). Set G101 Min Input and G102 MAX Input
to reflect the range of signal, typically 4-20mA or 0-10V. For more information, see page
89.
