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. Insert tubing into the compression fittings until the end

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. Make sure power is OFF when connectin

4. SPECIFICATIONS 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. F CALIBRATIONS: Performed at standard conditions [14.7 psia (1.01 bars) and 70 F F (21.1 C)] unless otherwise requested or stated.

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. INLET AND OUTLET CONNECTIONS: 1/4"compression fittings standard on ranges up to 50 L/min; 3/8” compression fittings standard on 60, 80, and 100 L/min ranges. Opt

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. Caution: If the valve is left in the AUTO (control) or OPEN mode for an extended period of time, it may become warm or even hot to the the  touch. Use car

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. On pin 6 of the FMA 1400 transducer is a regulated and constant +5VDC output signal. This signal may be used in conjunction with a local set point potentiome- ter for flow setting.

utilizing +15VDC valve configuration, connecting the TEST pin 12 on 15-pin "D" connectors) to ground will fully open the valve. For FMA 1400's with a +30VDC valve configuration, connecting the TEST pin to +15VDC will fully open the valve. 6. MAINTENANCE 6.1 Introduction It is important that the Mass Flow Meter/Controller is used with clean, filtered gases only. Liquids may not be metered. Since the RTD sensor consists, in part, of a small capillary stainless steel tube, it is prone to occlusion

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. Push the screen out through the inlet fitting. Clean or replace each of the removed parts as necessary. If alcohol is used for clean- ing, allow time for drying. Inspect the flow path inside the transducer for any vis

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. See section 7.4 for valve adjustment, to return the valve to functional use.] 7. CALIBRATION PROCEDURES Note: Removal of the factory installed calibration seals and/or an
