It is also preferable to install the FMA 1400/1500 transducer in a stable environment, free of frequent and sudden temperature changes, high moisture, and drafts. Prior to connecting gas lines inspect all parts of the piping system including fer- rules and fittings for dust or other contaminants. Be sure to observe the direction of gas flow as indicated by the arrow on the front of the meter when connecting the gas system to be monitored. - Page 8 FIGURE 2-1, WIRING DIAGRAM FOR FMA 1400/1500 TRANSDUCERS PIN FUNCTION Chassis Ground Common, Signal Ground For Pin 3 0-5 VDC Flow Signal +15 VDC Power Supply (-) 4-20 mA Flow Signal (optional) +7 VDC for Local Set Point (unassigned) TTL Valve Off Control (FMA 1400) Control Set Point Input 0 5 VDC (FMA 1400) Common, Signal Ground for Pin 9 Common, Power Supply...

Important notes: In general, "D" Connector numbering patterns are standardized. There are, how- ever, some connectors with nonconforming patterns and the numbering sequence on your mating connector may or may not coincide with the numbering sequence shown in our pin configuration table above. It is imperative that you match the appropriate wires in accordance with the correct sequence regardless of the par- ticular numbers displayed on your mating connector. -

FLOW MEDIUM: Please note that FMA 1400/1500 Mass Flow Meters and Controllers for ranges up to and above 10 L/min are designed to work with clean gases only. Never try to meter or control flow rates of liquids with any FMA 1500's or FMA 1400's. CALIBRATIONS: Performed at standard conditions [14.7 psia (1.01 bars) and 70... -

Omega7 makes no expressed or implied guarantees of corrosion resistance of mass flow meters as pertains to different flow media reacting with components of meters. It is the customers' sole responsibility to select the model suitable for a particular gas based on the fluid contacting (wetted) materials offered in the different models. -

Page 15: Flow Signal Output Readings
During initial powering of the FMA 1400/1500 transducer, the flow output signal will be indicating a higher than usual output. This is indication that the FMA 1400/1500 trans- ducer has not yet attained it's minimum operating temperature. This condition will automatically cancel within a few minutes and the transducer should eventually zero. -

age is a linear representation of 0 to 100% of the full scale mass flow rate. Response time to set point changes are 1 second (FMA 1400 for ranges up to 10 L/min) and 2 seconds (FMA 1400 for ranges above 10 L/min) to within 2% of the final flow over 25 to 100% of full scale. -
Page 17: Maintenance
To protect the instrument a 50 micron (FMA 1500/1400 for ranges up to 10 L/min) or 60 micron (FMA 1500/1400 for ranges above 10 L/min) filter is built into the inlet of the flow transducer. The filter screen and the flow paths may require occasional cleaning as described below. -

6.2.2 FMA 1400/1500 for ranges up to 10 L/min Unscrew the inlet compression fitting of meter. Note that the Restrictor Flow Element (RFE) is connected to the inlet fitting. Carefully disassemble the RFE from the inlet connection. The 50 micron filter screen will now become visible. -
Page 19: Calibration Procedures
Contact Omega7 for optional sealing materials available. Set the FMA 1400 into PURGE mode, and attempt to flush through with a clean, filtered, and neutral gas such as nitrogen. [Another option for fully opening the valve is to remove the plastic cap on top of the valve, and turn the set screw coun- terclockwise until it stops. -
Page 20: Calibration Of Fma 1500 Mass Flow Meters
All adjustments in this section are made from the outside of the meter, there is no need to disassemble any part of the instrument. FMA 1500 Mass Flow Meters may be field recalibrated/checked for the same range they were originally factory calibrated for. When linearity adjustment is needed, or flow range changes are being made proceed to step 7.3. -
Page 21: Zero Adjustment
LIKELY REASONS FOR A MALFUNCTIONING SIGNAL MAY BE: M Occluded or contaminated sensor tube. M Leaking condition in the FMA 1500 transducer or the gas line and fittings. M For gases other than nitrogen, recheck appropriate "K" factor from Gas Factor Table. -
Page 22: Zero Adjustment
7.3.2 ZERO Adjustment Shut off the flow of gas into the Mass Flow Meter. To ensure that no seepage or leak occurs into the meter, it is good practice to temporarily disconnect the gas source. Using the multimeter and the insulated screwdriver, adjust the ZERO potentiometer [R29] through the access window for 0 VDC (or 4 mA respectively) at zero flow. -
