Warning: Introduction of contaminants or corrosive materials to the module

pneumatic inputs may damage module transducers, manifolds, and O-ring seals.

The RS-232 interface is capable of supporting simple asynchronous communications with fixed

parameters of 9600 baud, no parity, 8 data bits, and 1 stop bit. Only

communication cable lengths less than 30 feet (10 m) are recommended.

The 9016, 9021 and 9022 use the diagnostic interface for optional configuration and diagnostic

purposes only. The diagnostic port functions on the 9016, 9021, and 9022 are generally not

required by the end user. Standard cables for these modules do not include diagnostic port

connections.

2.3.6 Pressure Connections

All pneumatic connections to Model 9016 are found on the instrument top panel. The function

of each input port is clearly engraved or printed next to each input. Connections are through

bulge tubing, compression fittings or special user-supplied fittings on the tubing plate. All

pneumatic inputs to these modules should contain dry, non-corrosive gas only. For Model

9021/9022, all pneumatic or hydraulic connections are to the individual 9400, 9401, or 9402 (or

third party) all-media transducers mounted externally from the module itself.

All 9016 standard Intelligent Pressure Scanners are supplied with the purge/leak check

calibration manifold. Through software commands, this valve may be placed in one of four

positions; RUN, CAL, PURGE, or LEAK-CHARGE. Pneumatic input requirements for these

four operating positions are described in the following sections.

The following guidelines should be used when installing pressure connections to all

NetScanner



System Intelligent Pressure Scanner modules.

• Always wear safety glasses when working with pressurized lines.

• Ensure that user input pressure will not exceed the proof pressure ratings of the

corresponding instrument transducer. Applying excessive pressure to

measurement inputs can permanently damage the pressure transducers.

• Ensure that all tubing material is rated for the expected pressure and

environmental conditions. Failure to use the proper tubing material may result

in ruptured lines and possible personal injury.

• Ensure all high pressure lines are properly secured.

• Place retaining springs over all bulge tube fittings to ensure pneumatic lines

remain attached and leak free. Springs should be pushed down on connections so

that half of the spring length extends past the tube bulge.
