WIRING PIN CONNECTOR

To access the terminals inside the DIN connector proceed as follows:

1. Remove the screw at the top of the connector.

2. Separate the DIN connector from the transducer.

3. Insert a small blade screwdriver into the slot provided and
pry the DIN connector apart.

4. After wiring the terminals, snap the DIN connector back together.

5. Mount the DIN connector to the transducer (using the rubber
gasket in between), observing the blade orientations.

6. Insert the screw at the top of the DIN connector and tighten.

WARNING! READ BEFORE INSTALLATION!

Fluid hammer and surges can destroy any pressure transducer and must always be avoided. A pressure snubber
should be installed to eliminate the damaging hammer affects. Fluid hammer occurs when a liquid flow is
suddenly stopped, as with quick closing solenoid valves. Surges occur when flow is suddenly begun, as when a
pump is turned on at full power or a valve is quicky opened.

Liquid surges are particularly damaging to pressure transducers if the pipe is originally empty. To avoid
damaging surges, fluid lines should remain full (if possible), pumps should be brought up to power slowly, and
valves opened slowly. To avoid damage from both fluid hammer and surges, a surge chamber should be installed,
and a pressure snubber should be installed on every transducer.

Symptoms of fluid hammer and surge's damaging effects:

1. Pressure transducer exhibits an output at zero pressure (large zero offset). If zero offset is less than 10% FS,
user can usually re-zero meter, install proper snubber and continue monitoring pressures.

2. Pressure transducer output remains constant regardless of pressure.

3. In severe cases, there will be no output.
