The CCR Model 400 is a high performance, microprocessor-based 4-channel power
supply/controller designed for use with Mass Flow Controllers (MFC). A linear regulator
provides a low noise, foldback current limited, thermal overload protected +15Vdc and
-15Vdc power supply @ 250mA each for each of the (4) MFC's. The CCR 400 accepts,
user selectable 0-5Vdc, 0-10Vdc or 4-20mA input signals. It also supplies 0-5Vdc, 0-10Vdc
or 4-20mA setpoint signals, for each channel, for flow control.
The firmware utilizes a Real Time Operating System (RTOS) for real time multitasking
capabilities. This allows continuous monitoring of each channel's flow rates, total flow and
setpoints regardless of the task being performed. A 16-bit multi-channel, high speed,
sigma-delta analog-to-digital converter provides accurate flowrate data. A 32K x 8 battery
backed RAM stores more than 90 Units of Measure and 190 Gas Identifiers selectable by
the user. All pertinent data, required by the microprocessor at power-up to re-initialize the
system, is also stored in the same RAM.
Ratio control is user selectable for master/slave operation. Channel 1 is always the master
and any of the other 3 channels may be selected as slaves. This master/slave arrangement
utilizes the actual flow of Channel 1 as the master signal.
The CCR400 utilizes a 4-line by 20 character back lighted LCD display. A built in Totalizer, one
for each channel automatically recognizes the units of measure selected and adjusts the
time base for the integrator accordingly. The user can select either Flow or Total to be
displayed for each channel. When selected, the setpoint signal is displayed and can be
altered via the front panel switches. Override controls for opening or closing the MFC
valves are also available for each channel. Annunciator LED's display the selected valve
override conditions.
Both RS232 and RS485 serial communications are available. All functions selectable from
the front panel switches are also accessible via the RS232/RS485 serial ports. Only one,
either RS232 or RS485, serial port is active at any one time. Selection, including a baud
rate of 9600 or 19.2K, is made via the front panel switches.
Each flow channel has a high and low user programmable alarm. The alarms activate an
opto-isolated open collector transistor output capable of switching 25Vdc @ 10mA.
The unit can be rack mounted using standard half-rack hardware or can be bench mounted
using the retractable stand provided. Input power is selectable, via the rear panel power
selector for 100, 115 or 230 Vac, 50-400 Hz.

The CCR 400 has a 100 Vac, 115 Vac or 230 Vac, 50/60 Hz power selector switch located at the rear of the
instrument. Please refer to page 4 to locate this switch. Verify the power selector switch is in the proper position
prior to connecting the power cable to the unit. Verify power ON/OFF switch is in the OFF position. Then perform
the following steps.
1. Connect the power cable to the instrument and apply the proper input power. Do not make any other
connections to the instrument.
2. Turn power ON/OFF switch ON.
3. The display will momentarily display the current version of the firmware utilized, then show the following
factory default display.
126.72 SCCM #1
126.72 SCCM #2
126.71 SCCM C3H6O
126.72 SCCM C2H3N
Note: All 4 channels should have the CLOSE annunciators illuminated. The values 126.71 and 126.72
are approximate and is the display for an open signal input . It may not correspond exactly to the
display shown on this unit.
4. Change the Units of Measure and Gas Identifiers as desired. Please refer to page 10. To blank the Units
of Measure select "00" then "ENT". To blank the Gas Identifier select "000" then "ENT". To blank the
entire line, please refer to RS232/485 Commands, Selecting/Blanking/Reading Display on page 21.
5. The CCR 400 is factory calibrated at 0.000 and 5.000Vdc to display 0.00 and 100.00 for each channel.
To change the display range, without recalibration, see MANUAL CAL/RANGE, Range(Changing Range)
on page 15. To enter a Gas Correction Factor or Multiplier, refer to MANUAL CAL/RANGE, Calibrate
(Multiplier) on page 16. The factory Multiplier setting is 1.0000.
6. The CCR 400 can accept 0-5Vdc, 0-10Vdc or 4-20mA input signals. If either 0-10Vdc or 4-20mA is
required, the instrument needs to be recalibrated. Select the proper signal input for the Transducer to be
used for each channel. Please refer to MANUAL SETUP, Selecting Input on page 11. Do not attempt to
recalibrate the instrument at this time. The factory Input setting is 0-5Vdc.
7. Select Filter to optimize reading stability and conversion speed. The factory Filter setting is 15Hz.
8. Allow 30 minutes warm-up time.
9. Turn power ON/OFF switch OFF.
10 . Connect Transducer #1 to J1 on the CCR 400 using the Connector Pin Designation information on
page 5. Connect all ground connections available to the transducer. Example: If the transducer has 3
ground pins, connect all three ground pins shown on J1. All ground pins on J1, J2, J3 and J4 are
common but are routed on separate wires from the connector to a ground plane on the instrument
motherboard.
11. Connect Transducers #2, 3 and 4 to the instrument. The instrument is designed to provide
+/-15Vdc @ 250 mA to each transducer. Do not use a Transducer that requires more than
+/-15Vdc @ 350mA on any channel.
12. Verify the display illuminates and the transducer readings are essentially correct. If the selected signal
input for a channel is 0-5Vdc proceed to Step 11 for that channel. If the selected signal input for a
channel is 0-10Vdc or 4-20mA, that channel needs to be recalibrated. Refer to MANUAL CAL/RANGE,
Calibrate section pages 14 and 15 to recalibrate that channel.
START-UP
PAGE 7

13. To utilize the Setpoint (Control) voltage for MFC's, set the Setpoint voltage for each channel to the
desired setting. Please refer to MANUAL SETUP, Selecting Setpoint (Control Voltage) on page 10.
The factory Setpoint default is 0.0000 for all 4 channels.
The Setpoint voltage, for a 0-5Vdc signal input, is calculated as follows.
Setpoint Voltage = (Setpoint Value/Range Value) * 5.000Vdc
Example: If the Setpoint Value = 120.00 SCCM and the Range Value is 250.00 SCCM,
the Setpoint Voltage = (120.00/250.00)*5.000 = 2.400Vdc.
For a 0-10Vdc signal input
the Setpoint Voltage= (120.00/250.00)*10.000Vdc = 4.800Vdc
For a 4-20mA signal input
the Setpoint Current = (120.00/250.00)*16mA + 4mA = 11.68mA.
14. The Flowrate Alarms are used to monitor the flowrate of the MFC. If the flow rate is not within the
selected HIGH and LOW Alarm values, an opto-isolated open collector output is activated. This output
can be used to illuminate warning lights to alert the user if the Flow Controller's Setpoint (Control)
voltage is not controlling the flow within a desired window. Refer to MANUAL SETUP, Selecting Alarms
on page 12. The factory default is HIGH Alarm set at 75.000, LOW Alarm at 25.000 and HYSTERESIS
at 010 counts.
15. To activate the Setpoint (Control) voltage to the MFC, select RUN for the desired channel. Reference
MANUAL SETUP, Selecting Valve Override (Open, Close or Run) on page 9. The default at power-up
is Valve Close.
16. If the Units of Measure are in flow units, the CCR 400 automatically calculates TOTAL flow using a
Riemann Sum Integration method. To display TOTAL or to reset the TOTAL display, refer to
MANUAL/SETUP, Selecting Display (Flow or Total) on page 9. If the Units of Measure are not in flow
units, the TOTAL is not calculated or displayed.
17. The CCR 400 has both RS232 and RS485 serial communications ports. Only one port is active at any
one time and is user selectable. The RS232 port has (1) 9-pin D-sub connector, while the RS485 port
has (2) 9-pin D-sub connectors. All Setups described earlier can be performed using the serial
communications ports. Reference RS232/485 Hookup and Commands on pages 17 through 26.

Selecting Display (Flow or Total)
If Flow is selected, the most significant digit location will be left blank. If Total is selected, a "T" appears in
this location and the Unit of Measure changes accordingly. If the Unit of Measure selected is not a flow
rate unit of measure, Total will not be displayed.
Selecting Valve Overide (Open, Close or Run)
Channel 1 is shown selected above. An asterisk appears to signify the Channel selected. To select
Channel 2, depress CH SEL switch twice, then select OPEN, CLOSE or RUN. If OPEN is selected,
ground is applied to the appropriate channel connector pin-4. This ground is at the same potential as
pin-9. If CLOSE is selected, ground is applied to pin-12. Both pin-4 and pin-12 are grounded with an
open collector transistor capable of sinking 250mA at 25V. If RUN is selected, no override signals are
sent and the MFC Setpoint control is activated.

Selecting Setpoint (Control Voltage)
The example above shows how the setpoint for Channel 2 is changed. When CH SEL is depressed an
asterisk points to the channel selected. To select Channel 4, depress CH SEL switch 4 times. The value
displayed after the asterisk is the current setpoint value. Typing in a new value overrides the old value. If
ESCis depressed instead of ENT, the old value is retained.
Selecting Units of Measure and Gas Identifiers
The bold characters shown in the above flow chart indicate the updated Units of Measure and Gas
Identifier selected. Note: When the Units of Measure and Gas Identifiers are selected, ENT must be
depressed before the selection is made. This is because it may require the inputting of more than 1 digit
to make the desired selection.

Selecting Filter (-3db A/D Converter Filter Frequency)
The Filter selection sets the output word rate which in turn sets the corner frequency for the sigma-delta A/D
converter. With an output word rate of 15Hz, the filter's corner frequency is typically 12.7Hz. The filters are
optimized to settle to full accuracy every conversion and yield better than 80dB rejection for both 50 and 60Hz
with output word rates at or below 15Hz. The last filter output word rate setting for the selected channel is
displayed for user convenience. Each channel may be set to a different filter output word rate. The factory
default is15Hz for each channel to optimize response time and noise rejection.
Selecting Input (0-5Vdc, 0-10Vdc or 4-20mA Signal Input)
The Input selection sets the full scale input signal and the full scale setpoint (control) signal for the selected
channel. The selected channel and the input signal setting that was previously selected is displayed during
selection. The factory default is 0-5V for each channel. Any input may be selected for any channel. The
instrument compensates for any incompatibilities even in the Master/Slave configuration.
Example: If the full scale input selected is 0-10V, then the full scale setpoint output is also 0-10V. If the
Master Channel is 0-10V and the Slave Channel is 4-20mA, the instrument compensates for the
incompatibility and sends a 0-10V setpoint signal for the Master and a 4-20mA setpoint signal proportional to
the 0-10V input signal for the Slave.
Note: For most MFC's the full scale input is 0-5V, while for pressure transducers the input is 0-10V.

Selecting Alarms (High and Low with Hysteresis)
Each channel has a HIGH and LOW alarm to monitor the flow rate signal. If the flow rate is higher than
the HIGH alarm or less than the LOW alarm, an optically isolated open collector output is turned on. This
alarm may be used as a warning that the flow rate is not within the limits set by the setpoint (control)
signal. A programmable HYSTERESIS of 1 to 999 counts provide a deadband for the alarms. To exit the
alarm setup a "4" to exit must be selected.
In the above example, the HIGH alarm limit was changed from 75.000 to 50.000, the LOW alarm limit from
25.000 to 10.000 and HYSTERESIS from 010 to 001. The factory default is 75.000, 25.000 and 010 for
the HIGH, LOW and HYSTERESIS settings, respectively.

Calibrate (Zero only)
The "Zero only" sequence shown above is used to zero the MFC. Verify the input signal is at or
close to zero prior to performing this sequence. In SCREEN 5, the data shown after "SIGNAL" is the raw
analog-to-digital data corresponding to the input signal applied. This data is live and will change as the
input signal is changed. It should be close to zero, unless the MFC is being zeroed at a point other than
zero. If ENT is depressed during SCREEN 5, the value present at the input will be zeroed on the display,
as shown in SCREEN 6. If ESC is entered, the previous zeroed value applies.
Calibrate (Range only)
The Range only sequence is used to calibrate the full scale reading of the MFC. Apply a full scale input
signal, typically 5Vdc to the signal input prior to performing this sequence. At SCREEN 5, the user has 2
alternatives. The first is to accept the display RANGE value shown by depressing ENT. The second is to
enter a new RANGE value, as shown above, prior to completing the RANGE sequence. The Signal
displayed on SCREEN 6 is the live, un-scaled analog-to-digital converter data, and will change as the
input changes. The value present when ENT is depressed will be used in the full scale calibration
calculations. If ESC is entered instead of ENT, the previous calibration applies. NOTE: DO NOT USE
THE RANGE ONLYSEQUENCE TO CHANGE RANGES. USE SELECTION 2 SHOWN IN SCREEN 2.

Calibrate (Zero & Range)
The Zero & Range calibration allows both zero and full scale calibrations to be performed in the same
sequence. The input signal needs to be changed from a zero to a full scale value during the calibration
sequence. The same rules apply as previously mentioned in the Zero only and Range only procedures.
Range (Changing Range)
The Range sequence is nota calibration sequence. Changing the Range value simply replaces the
Range value used during the previous full scale calibration. The analog-to-digital converter data used
during the previous full scale calibration is still valid. Ranging is a simple way to change ranges when
changing MFC's. It assumes the full scale output voltage of the new MFC is the same as the previous
MFC.

Calibrate (Multiplier)
Entering a MULTIPLIER value changes the display by that multiplier factor. All data values are multiplied
by the MULTIPLIER prior to display. The MULTIPLIER is sometimes referred to as a GAS
CORRECTION factor when used with MFC's. If the MFC is calibrated with nitrogen and another gas is
used with the MFC, a GAS CORRECTION factor can be entered to recalibrate the MFC to the gas used.
