Setra 328 Operating Manual

Setra Local Display
Model 328
Installation and Operating Instructions
1.0 INSTALLATION
Setra’s Model 328 is a small, local display designed for installation in high density modular block gas sticks and panels. It can be used with voltage output and current output transducers using 15 Pin and 9 Pin D-Sub connectors. Consult Table 2, the Configurable Part Number Chart on page 3, to determine the configuration that is supplied. For setting optimum viewing angle, the 328 display housing can rotate 360º degrees. A built-in positive stop limits the rotation of the front portion to a maximum of 360º degrees. If resistance is encountered when trying to rotate in one direction, rotate in the opposite direction.
2.0 ELECTRICAL CONNECTIONS
The 328 can be supplied with either a 15 Pin high-density or 9 Pin D-Sub connector to the input transducer and to the power supply. Confirm the electrical connection supplied, and refer to the appropriate column below for proper connections.

2.3 EMC Certification
This product complies with EMC Directive 2004/108/EC per EN61326-1 Electrical Equipment for Measurement, Control and Laboratory use – EMC Requirements. In order to meet the EMC requirements, the following conditions must be followed during installation:
1. Shielded cable must be used, and the shield must be tied to earth ground (not power supply ground) on at least one end of the cable shield/drain wire. The shield must be maintained all the way from sensor to the power supply.
2. If unshielded cable is used, an earth grounded metal conduit fitting can be used to replace the shielded cable.

3. For a sensor with a metal body or enclosure, the body/enclosure must be grounded to earth. If a protective metal housing is used, the metal housing should be grounded to earth
2.4 RoHS Compliance
The Model 328 complies with the European Union (EU) RoHS Standards for the elimination of hazardous and non-environmentally friendly materials. The product is so marked as to desig­nate its compliance only on its external packaging.
3.0 MECHANICAL INSTALLATIONS
The Model 328, with its rotating front face, requires the use of a locking pin to maintain rigid installation with its mating transducer. This is accomplished by means of a locking pin on the Model 328 display. This locking pin engages with a matching bracket/hole on the interfacing transducer. This locking pin is replaceable should it become damaged during repeated installa-
tion events.
4.0 CALIBRATION
The 328 is factory calibrated to display engineering units. Setra recommends that the zero adjustment be done using the transducer zero potentiometer, whenever possible. The display zero should only be used for minor adjustments. Never adjust the span unless proper calibra-
tion equipment is used and proper calibration procedures are followed.
4.1 Auto Zero & Auto Span Adjustment
The auto zero and auto span adjustment buttons are located on the front of the unit just under the digital display. See Table 1 for details of functionality.
1. AUTO ZERO: Apply zero pressure to the transducer and adjust the 328’s zero if the 328 does not display ZERO reading accurately. Press and Hold the ZERO button and at the same time press and hold the ENTER button for 2 to 3 seconds.
2. AUTO SPAN: Apply full scale pressure to the transducer and adjust the span on the 328. Press and hold the UNITS button, and at the same time press and hold the ENTER button for 2 to 3 seconds. Make sure the display zero is accurate before adjusting auto span.
CAUTION: If you do not press the ENTER button within 5 seconds of pressing the UNITS but-
ton, the displayed units will change. (See section 4.3, page 3)
4.3 Pressure Units Change
The Model 328 is capable of changing the Pressure units by pressing and holding UNITS buttons for 5 seconds An illuminated LED will light under the respective Pressure Unit (e.g., “PSI”, “Bar”, or “KPa”). The unit conversion factors are pre-configured at the factory. Consult factory for re-
configuration when necessary.
4.4 Overflow/Underflow
The Model 328 will display an overflow or underflow condition by means of a visual indication. When in Overflow condition, the Model 328 will exhibit an “OUF” on the LED display. When in an Underflow condition, the
Model 328 will exhibit an “UDF” on the LED display.
