Product Overview
2-1
Advanced Energy®
When gas flows through the MFC it is split into two streams. A larger stream is routed
through the bypass assembly, and a smaller stream that is proportional to the larger
stream is routed through the flow sensor. The MFC is designed so that the ratio
between these two streams remains constant over the entire measurable flow range of
the instrument.
The flow sensor measures the flow of the smaller stream which represents the total gas
flow through the MFC. The flow sensor consists of a small stainless steel capillary
tube with two thermal resistors wound around the outside. Current passes through the
thermal resistors that function as heaters to warm the sensor tube. The thermal
resistors form part of a bridge circuit that senses the resistors’ resistance balance.
When gas is flowing, heat is transferred from the upstream to the downstream thermal
resistor. The degree of imbalance is proportional to the rate of the gas flow.
The control valve adjusts gas flow through the MFC based on the flow sensor reading
and the set point to ensure a stable gas flow from the MFC.
For more detailed information regarding the components in the MFC, see “MFC
Components” on page 2-2.
MFC COMPONENTS
The main components of the MFC are the flow sensor, bypass, electronics (bridge,
amplifier, and comparator circuits), and valve assemblies. Figure 2-2 illustrates these
major components.

Figure 2-2. MFC functional block diagram
Flow Sensor Assembly
The flow sensor consists of a capillary tube wound by two self-heating resistance
wires through which electrical current is passed. The resistance wires heat the sensor
tube and when gas flows through the flow sensor a temperature differential is
produced between the upstream and downstream wires. The temperature change
causes a change in resistance which is detected as an electronic signal by the bridge
circuit of the electronics assembly.
The MFC uses the mass gas flow measurement because the heat exchange between
the gas and the self-heating resistance wire depends on the mass flow. When gas is not
flowing, heat is distributed evenly over the upstream and downstream wires, therefore
the resistance of upstream and downstream wires is equal and the bridge circuit
outputs zero. When gas flows, heat is exchanged between the gas and the self-heating
resistance wires. The temperature distribution between the upstream and downstream
resistance wires changes causing an imbalance. The imbalance of the upstream and
downstream temperatures results in a resistance differential that is detectable by the
bridge circuit as an electronic signal. The electronic signal represents the mass gas
flow.

Product Overview
2-3
Advanced Energy®
As a result of the techniques of thermal mass flow measurement, gas flow can be
measured independently of factors which affect volume and density, such as
temperature and pressure.
Bypass Assembly
The bypass assembly diverts a small stream of incoming gas through the flow sensor
and channels the rest through the bypass and toward the valve assembly of the MFC.
The bypass assembly design ensures a constant flow ratio between the flow sensor and
the larger flow passing through the instrument, making the output signal of the flow
sensor proportional to the total (or mass) gas flow. A comparator circuit in the
electronics assembly compares the output signal from the flow sensor and the flow set
point. The signal created from this comparison drives the control valve until the
difference between the set point and the sensor output signal decreases to zero.
Electronics Assembly
The electronics assembly consists of a bridge circuit, a high resolution analog
converter, a valve drive circuit, and an analog I/O. The signal generated by the bridge
circuit is amplified and fed into the analog converter which outputs this signal into the
CPU (central processing unit). The CPU compares the set point signal to the sensor
reading to generate a signal to drive the control valve.
Valve Assembly
The valve assembly consists of a normally closed or normally open, solenoid control
valve.

Installation and Operation
5700512-C
Series FC-77X / 77XX, Series FC-78X / 78XX, and Series FC-79X MFCs
Hazardous voltages exist inside the mass flow controller (MFC). Do not
remove the MFC cover.
First-Time Operation
The first time you operate the MFC:
1. Ensure that you have installed the MFC properly by following the procedures in
“Installing the Unit” on page 3-2.
2. After energizing the MFC (turning on power) through the appropriate
communications interface, allow the MFC to warm up for at least 15 minutes
before supplying gas to the MFC.
If you observe deviation in the zero output, perform a zero-point adjustment (see
“Zeroing the MFC” on page 3-9).
3. When using the MFC with vapors at room temperature, set the supply pressure at
the minimum value capable of securing the full-scale flow rate to avoid liquid
recondensation in the pipes. Be sure to maintain stable temperature for all pipes.
Zeroing the MFC
Look to the following information to adjust the MFC to the zero point.
Note: Contamination can negatively affect proper flow rate control and measurement,
despite zero point adjustment.
Before Zeroing the MFC, Review the Following:
• Make sure that your MFC has a zero-point adjustment hole. To identify this hole,
see Figure 3-4 on page 3-10. If your model does not have this hole, you can not
adjust the zero point. In this situation, contact AE Global Services (see “AE
Global Services” on page 5-6).
• The MFC can be mounted in any position. However, if the MFC is in a vertical
position, thermal siphoning can occur with a gas that has a molecular weight that
is 140 or less, which may cause the zero point to shift. Make sure to adjust the zero
point in the intended mounting position and with pressured service gas.
• Adjust the zero point at the service operating temperature. Temperature
deviations, even within the specified range of operating temperatures, may cause
the zero point to shift.

Advanced Energy®
To Adjust the MFC Zero Point:
1. Make sure that the MFC has reached ambient temperature.
2. Energize the MFC, then wait at least 15 minutes. During this time, make sure that
the ambient temperature remains constant and that the output stabilizes.
3. Close the shut-off valves upstream and downstream of the MFC to ensure that
there is no gas flow.
4. For normally closed MFCs set the set point signal to 0 V. For normally open
MFCs, set the set point signal to 5 V. For more information on the set point
command, see Chapter 4, “I/O Connections and Communication.”
5. Use a small, flat head screw driver to make the zero-point adjustment as shown in
Figure 3-4.

MAINTENANCE
Recalibration and repair should be performed by Advanced Energy. See “AE Global
Services” on page 5-6 for contact information.
Note: Removal of an MFC should be done only after adequate purging with a
nonreactive gas such as nitrogen gas (N2). You should follow your company
procedures for removing gas line components.
Reactive gas calibrated MFCs may receive severe contamination or
corrosion from exposure to air or moisture. Check plumbing for leaks,
and purge thoroughly with dry nitrogen before operating or
disconnecting from the system.
STORAGE
Observe the following requirements when placing an MFC in storage:
• Temperature between 5ºC (41ºF) and 45ºC (113ºF)
• Relative humidity less than 60%
Additionally, prevent any mechanical impact or corrosion.

SPECIAL FUNCTION SIGNAL DESCRIPTIONS
The following sections provide detailed signal information for signals that are
dedicated to specific functions.
Alarm Output (Error Detection) Signals
Not all MFC models provide these signals. To see if your model provides alarm output
signals see the specifications for the MFC model in question (see “Model
Specifications” on page 6-1). For signal descriptions, see Chapter 4, “I/O Connections
and Communication.”
FC-77X and FC-77XX MFCs provide error detection as a standard feature. The
function is an option on some other models.
For MFCs with the error detection feature, the MFC provides alarm output if it detects
a difference between the flow rate set point and the actual flow rate for longer than
eight seconds.
5700512-C
I/O Connections and Communication
4-7
Advanced Energy®
As shown in Figure 4-4, ALARM H and ALARM L are connection terminals for the
open collector that is isolated with the photocoupler. To use the terminals, apply
appropriate power, as shown in the illustration. Use the ALARM ON/OFF signal to
reset the signal.
Note: If no gas is being supplied, but the MFC has a nonzero set point, the MFC will
report an error (because the flow rate does not match the set point).
Figure 4-4. Alarm connection
Control Valve Purge Function Signals
The control valve purge function allows you to completely open the control valve and
purge gas at many times the MFC full-scale flow rate. This function is particularly
useful for purging gas when using MFCs with a low full-scale flow rate or for leak
checking. The settings for opening/closing the control valve vary with the connector
type and, in some cases, with whether the MFC is normally open or normally closed.
For most applications, this signal is not connected.
The following illustrations show the connection and the internal MFC wiring, for the
purge function signals on all connectors.

RETURNING MFCS FOR REPAIR
Before returning any product for repair and/or adjustment, first follow all
troubleshooting procedures. If, after following these procedures, you still have a
problem, or if the procedure instructs you to, contact AE Global Services and discuss
the problem with a representative. Be prepared to give the model number and serial
number of the MFC, as well as the reason for the proposed return. This consultation
call allows Global Services to determine whether the problem can be corrected in the
field or if the MFC needs to be returned. Such technical consultation is always free of
charge.
If you return an MFC without first getting authorization from Global Services
and that MFC is found to be functional, you will be charged a re-test and
calibration fee plus shipping charges.
If you have received authorization for return, see “Packing an MFC for Shipping” on
page 5-10 for more information on packing the MFC for shipping.
To ensure years of dependable service, Advanced Energy® products are thoroughly
tested and designed to be among the most reliable and highest quality systems
available worldwide.
Packing an MFC for Shipping
Prior to shipping an MFC back to AE for repair or return, you must
receive authorization from AE Global Services. For more information,
see “Returning MFCs for Repair” on page 5-10.
Observe the following requirements when packing an MFC for shipment:
• Obtain a return authorization number from Global Services.
• Include the appropriate material safety data sheet (MSDS) information. Without
this information, AE will return the MFC to you without repair.
• Follow your company procedures for purging and removal of an MFC.
• Seal the MFC end-fittings for shipping.
• Place the MFC in two plastic bags (double-bag packaging) for shipment. Be sure
to vacuum seal each bag.
Pack the MFC with sufficient shock absorbent material to prevent damage to MFC’s
plastic bag from vibration or impact during shipment.

WARRANTY
All MFC warranties are void if the seal on the MFC cover is broken or
removed.
Advanced Energy® (AE) products are warranted to be free from failures due to defects
in material and workmanship for 12 months after they are shipped from the factory
(please see warranty statement below for details).
In order to claim shipping or handling damage, you must inspect the delivered goods
and report such damage to AE within 30 days of your receipt of the goods. Please note
that failing to report any damage within this period is the same as acknowledging that
the goods were received undamaged.
For a warranty claim to be valid, it must:
• Be made within the applicable warranty period
• Include the product serial number and a full description of the circumstances
giving rise to the claim
• Have been assigned an RMA (return material authorization) number (see below)
by AE Global Services
All warranty work will be performed at an authorized AE service center (see list of
contacts at the beginning of this chapter). You are responsible for obtaining
authorization (see details below) to return any defective MFCs, prepaying the freight
costs, and ensuring that the MFCs are returned to an authorized AE service center. AE
will return the repaired MFC (freight prepaid) to you by second-day air shipment (or
ground carrier for local returns); repair parts and labor will be provided free of charge.
Whoever ships the MFC (either you or AE) is responsible for properly packaging and
adequately insuring the MFC. See “Packing an MFC for Shipping” on page 5-10 for
more information on packing the MFC for shipping.
Authorized Returns
Before returning any product for repair and/or adjustment, call AE Global Services
and discuss the problem with them. Be prepared to give them the model number and
serial number of the MFC as well as the reason for the proposed return. This
consultation call will allow Global Services to determine if the MFC must actually be
returned for the problem to be corrected. Such technical consultation is always
available at no charge.
MFCs that are returned without authorization from AE Global Services and that are
found to be functional will not be covered under the warranty (see warranty statement,
below). That is, you will have to pay a retest and calibration fee, and all shipping
charges.

Series FC-77X / 77XX, Series FC-78X / 78XX, and Series FC-79X MFCs
REFERENCE INFORMATION
The following sections contain calibration references, as well as MFC label and model
code information for the MFC.
Calibration References
In order to ensure MFC cleanliness, AE may use a surrogate calibration gas rather
than the gas indicated on the label. The calibration ambient temperature is 22ºC. (If
the MFC requires a different ambient calibration temperature, that temperature is
indicated on the MFC label.)
Note: The calibration gas and its conversion factors are subject to change due to
technological innovation or changes in environmental regulations.
Table 6-37. Calibration references
Description
Specification
Calibration method
Primary, secondary, or rate of rise of N2 (or other
surrogate gas)
Reference conditions
0ºC / 760 Torr per SEMI E12-96
Traceablity
All calibrations are traceable to Japan standards
and/or United States standards (NIST)
FLOW INDICATION
Flow rate is indicated by standard cubic centimeters per minute (sccm), cubic
centimeters per minute (ccm), standard liters per minute (slm), and liters per minute
(lm) as follows:
• For sccm and slm, gas flow rates at 0ºC, 101.3 kPa
• For ccm and lm, gas flow rate at customer-defined temperature, 101.3 kPa
Note: Unless otherwise noted, sccm and slm are used for calibration.
