I Safety Information
Explosive Gases
WARNING!
Do not use the Model 906A Convection Gauge Controller to measure
the pressure of combustible gas mixtures. The gauge normally operates
at low temperatures, but it is possible that momentary transients or
controller malfunction can raise the gauge above the ignition tempera-
ture of combustible mixtures, which then might explode and cause
damage to equipment and injury to personnel.
Limitation on use of Compression Mounts
WARNING!
Do not use a compression mount (quick-connect) for attaching the
gauge tube to the vacuum system in applications that may develop pos-
itive pressures. Positive pressures may cause the tube to be blown out
of a compression fitting and damage equipment and injure personnel.
Chemicals
WARNING!
Many organic cleaning solvents, such as acetone, produce fumes that
are toxic or flammable. Use such solvents only in areas that are well
ventilated to the outdoors and away from electronic equipment, open
flames, or other potential ignition sources.

IV Installation
A. Unpack the Controller
Carefully unpack the Model 906A Convection Gauge Controller.
The shipment includes these components:
• controller unit
• power cord
• mounting clips
•DB15 accessory connector
• this instruction manual
If your controller does not have all of these items, call Duniway Stockroom. If it appears to have
been damaged in shipment, contact the shipper.
B. Mount the Controller
You can mount the controller unit freestanding on a bench, table top, or shelf, or you can mount
it in a rack or cabinet. The controller unit is housed in a standard 1/8 DIN box.
If you are mounting the unit in a panel, the cutout dimensions are 44 mm by 92 mm. One mount-
ing clip attaches to each of the sides of the controller unit. To attach the clip, slide the beveled
surfaces of the clip under the cutout on the side of the box and push the clip toward the back of
the unit until the central tongue locks the clip in place. Then slide the unit into the panel; the clips
will hold the unit in place.
Be sure to leave enough clearance at the back of the controller unit for easy access to cable con-
nections.
C. Select the Gauge Tube
The Model 906A controller is designed to work with the Granville-Phillips CONVECTRON®, series
275 or HPS/MKS Enhanced Convection Pirani, series 317 tubes. If you have difficulty obtaining
a gauge, please contact us at Duniway Stockroom.
CAUTION
Use of a gauge tube other than those listed above may cause improper
readings, and may cause damage to the gauge tube.

D. Connect the Gauge Tube
Make sure that the gauge tube is securely connected to the vacuum system, using good vacuum
practice. The gauge tube must be mounted with its axis horizontal, and the port pointing down;
large errors may result at higher pressures if the gauge axis is not horizontal.
E. Attach the Gauge Cable
The gauge cable has a special connector for the gauge on one end and a 15-pin DB connector on
the other. Be sure to use the cable supplied with the Model 906A.
CAUTION
Make sure that the power to the controller unit is off before you connect
the gauge tube to the controller unit. Unplugging and then plugging in
the gauge cable with the power on can cause the gauge to burn out.
Connect the gauge cable to the gauge tube. Align the keyway of the connector with the key on the
gauge tube, and push the connector onto the gauge tube’s pins until it seats firmly.
Connect the 15-pin DB plug of the gauge cable to the 15-pin DB jack on the back of the controller
unit. Push the plug onto the jack until it is firmly in place. Tighten the retaining screws to make
certain the connector remains in place. Loose connections can damage the gauge.
NOTE
If you have a cable from one of the analog display Granville-Phillips
CONVECTRON® gauge controllers, it is an easy task to convert the cable
for use with the Model 906A. The analog controller uses a combination
cable for the CONVECTRON® gauge and for AC power input. To con-
vert the cable:
• You must have a DB15 connector with male pins; a connector with solder
cups is an easy version to work with. If you have difficulty locating one of
these, call us and we will send you one.
• Identify the cable which plugs into the CONVECTRON® gauge.
• Follow the cable to the edge-connector and cut the cable, separating the ca-
ble from the edge-connector.
• Remove the jacket of the cable, about 1.5 inch (40 mm).
• Strip the wires, about 0.25 inch (0.5 mm).
• Observe the pin numbers identified on the CONVECTRON® gauge con-
nector and the DB15 connector.
• Connect as follows (Granville-Phillips colors are shown, but you should
verify the connections with a continuity checker): see next page.

You can set two process control set points from the front panel of the controller (SET PT 1) and
SET PT 2). The set points control two relays that are accessible through the connector on the back
of the controller. SET PT 1 controls relay #1, and SET PT 2 controls relay #2. Relay contacts are
available through the DB15 Accessory Connector.
NOTE: See also Section VIII - Application Note - Protective Circuits for Set Point Relays
G. Accessory Connector
The Accessory Connector is the top DB15 connector on the rear panel of the 906A. The connector
has female pins, the mating connector must have male pins. If you need help identifying a con-
nector source, please contact us. Following are pin assignments for the Accessory Connector:

H. Check Voltage Setting
The Model 906A incorporates a universal power supply. This allows the 906A to operate on any
input voltage from 85 VAC to 240 VAC, 50/60 Hz. Earlier versions of the 906A, with serial number
lower than 2310 are not of this universal design. If you are in doubt as whether your 906A is uni-
versal input, please check the 906A rear panel for the recommended input voltage.
I. Attach the Power Cord
Plug the power cord into the receptacle in the power module. Plug the other end of the power cord
into an electrical outlet.

V Operation
A. Turn Power On
The loudspeaker will “beep” and all indicators will light for a few seconds while the controller
executes its self test. After the self-test, the display will show:
- the model number, e.g. 906,
- the software version, e.g. 1.20 for a second;
- then it will display the units of measure, torr or mbar, e.g. TOR or BAR for one second
- then the sensor curve chosen, 275 or CEP.
The 906A will then begin measuring pressure. If the gauge cable is not connected, the display will
show OFF. If the system pressure is greater than 990 Torr (mbar) or if the gauge is disconnected
from the cable, the display will show HI.
B. Choice of Model 317 HPS/MKS CEP or Model 275 Convectron®Response Curves
Default: G-P Model 275 Convectron®(“275”)
The “CEP” tube and the “275” tube have slightly different response curves over the 7 decades of
pressure indication. In order to provide the most accurate pressure indication, the user is offered
the choice of response curves, depending on the sensor tube chosen.
To change from “275” to “CEP” response curves, unplug the 906A from its power source. Press
and hold RAISE and SELECT buttons at the same time; while holding the RAISE and SE-
LECT buttons depressed, plug the power cord in. You will hear a two short ‘chirps’ from the
loudspeaker confirming the response curve has been changed. The digital display will show CEP
to confirm the reset has been entered. This process can be reversed by following the same proce-
dure. The unit will be returned to the 275 response curve during Reset of Stored (Default) Values.
C. Calibration
You can set the zero point of the display or calibrate it to atmospheric pressure; in addition, you
can recover the factory settings. These calibrations use the SELECT, RAISE and LOWER buttons.
D. Setting to Zero
The system pressure should be lees than 1 mTorr (1µbar).
Press the button labeled SELECT. You will hear a short ‘chirp’ from the loudspeaker and the VAC
LED will flash; you may now use RAISE and LOWER to set the pressure to zero. The actual pressure
must be less than approx. 50 mTorr (65 µbar); if you try to set zero pressure when the instrument
is greater than 50 mTorr (65 µbar), you will get a long beep from the loudspeaker.

E. Setting Near Zero
The display may be set to a specific value near zero. For example, if you know that the system
pressure is 10 mTorr (10 µbar), you can set the display to agree with this value, as follows: while
in VAC adjust, press RAISE or LOWER to set to the desired value. If the system pressure is greater
than approx. 50 mTorr (65 µbar), you cannot make these adjustments.
F. Setting Atmosphere
You should know the local barometric pressure before proceeding; your local airport may have
this information. Normal pressure is approximately 760 Torr (1000 mbar) at sea level.
Press the button labeled SELECT until the ATM LED is flashing. You may now use RAISE and LOW-
ER to set the pressure to the desired pressure. If you try to set ATM pressure when the pressure is
less than approx. 200 torr (350 mbar), you will get a long beep from the loudspeaker. As the dis-
play changes, you will hear a series of ‘chirps’ from the loudspeaker.
G. Reset of Stored Values
This allows recovering the factory settings for VAC and ATM and resets SET POINTS to minimum:
For a system that is far out of calibration, the factory settings provide a good starting point for re-
calibrating the gauge controller. This procedure also enters OFF for the set points. To recover the
factory settings, unplug the 906A for its line voltage power source. Press and hold RAISE and
LOWER buttons at the same time; plug the power cord in. You will hear a few short ‘chirps’ from
the loudspeaker confirming the factory settings have been entered.
H. Changing Units of Measurement
This allows you to change from measurement in Torr to mBar or from mBar to Torr. The internal
software allows the 906A to display pressure in either Torr or mBar. The 906A is shipped with
the unit of measure which was specified at the time of the order. If you wish to change the units
of measure, remove power form the 906A by unplugging it from the AC mains. Press and hold
all three buttons, SELECT, RAISE and LOWER; plug the AC power in and wait for the two “chirps”
from the loudspeaker to confirm the units change. After the display self-test, the display will show
TOR or BAR, to confirm the selected units.
NOTE: Make certain that the labels on the front panel units (torr and mTorr; or µbar and mbar)
match the selected units. If you need a different display overlay, please let us know. This proce-
dure is a bit inconvenient, but it is not intended to be a function that is changed often.

I. Set Point Operation
When the displayed system pressure is less than the value of the set points, the set point relay is
turned on; the corresponding LED lights to indicate that the relay is energized. The relay will be
turned off when the pressure rises to 5% above the set point, plus 1 mTorr. For example:
If the set point is 30 mTorr, the set point relay will turn on at 30 mTorr; it will turn off at
[30 + 0.05*30 + 1]=32.5 mTorr, and higher pressures.
If the set point is 3 mTorr, the set point relay will turn on at 3 mTorr; it will turn off at
[3 + 0.05*30 + 1]=4.0 mTorr, and higher pressures.
If the set point is 1 torr, the set point relay will turn on at 1.00 torr; it will turn off at
[1.00 + 0.05*1.00 + 0.001]=1.05 torr, and higher pressures.
NOTE: See also Section VIII - Application Note - Protective Circuits for Set Point Relays
J. Reading the Set Points
To see the value of a set point, push the SELECT button until the desired SET PT LED is flashing.
K. Setting the Set Points
The range for the set point settings is from 3 mTorr (mbar) to 500 torr (mbar). The OFF setting
disables the set point control and keeps the relays from operating. The OFF setting is the lowest
setting, below 3 mTorr (µbar).
To set a set point, push the SELECT button until the desired SET PT LED is flashing. The display
will indicate the current value of the set point. Use the RAISE and LOWER buttons to adjust the set
point to the desired value. As the indication changes, you will hear short ‘chirps’ from the loud-
speaker.
NOTE:
When using the SELECT button, the display will remain in the selected func-
tion until the SELECT button is pushed again; or if no button is pushed for 60
seconds, the instrument will revert to normal operation. This automatic reset
is to prevent any error to process control if the instrument is left in the adjust
mode.

L. Analog Output
The analog output is calculated from the value of the digital display. The output is logarithmic,
0.5 volt/decade; the source impedance for the output is 10 K ohm. The output voltage is calculated
from:
V=0.500(log10P)
where V is the Analog Output in volts; P is the pressure in mtorr or µbar.
The pressure as a function of the Analog Output voltage is:
P=log-1(2V)or
P=10(2V)
where P is pressure in mtorr or µbar; V is the Analog Output in volts.
Some examples follow; because of normal tolerances in the electronics, there may be minor dif-
ferences in the values you observe compared to those shown:

M. Serial Interface
The serial port gives pressure readings when requested by the RS-232 terminal. The interface is
standard RS-232 format; 9600 baud, 8-bits, no parity, 1 stop bit. The interface is through the
DB15 accessory connector.
pin 7 is Tx (signal from terminal to the 906A)
pin 8 is Rx (response from the 906A to the terminal)
pin 9 is return (ground).
To get pressure readings, send a lower case “p” (ASCII value 112). Output is converted from
the digital display, in the following format:
WXYeZ, where WXY is the multiplier and Z is the exponent; Some examples follow:

To read the stored Set Points, send a “1” (ASCII value 49) or “2” (ASCII value 50) to read Set
Point 1 or Set Point 2. Output is in the same format as for pressure readings. An added digit shows
whether the Set Point is active (system pressure is lower than the set point, and the set point relay
is energized); this digit is “0” when the set point is not active (set point relay is off), and is “1”
when the set point is active (set point relay is on).
To read the units of measure, send a lower case “u” (ASCII value 117); this returns “torr” or
“mbar” depending on the units selected.
To read the type of Convection Gauge Selected: Send “x” (ASCII value 120); the 906A returns
the type of convection sensor tube selected, either HPS/MKS CEP or Granville Phillips 275 Con-
vectron®, as in the following example:
CEP or 275
To read the Model Number and Revision Level: Send “v” (ASCII, value 118); the 906A re-
turns “906 ver 1.20”

For example, if you are measuring the pressure in a system that is backfilled with argon, and the
Model 906A display shows an indicated pressure of 23.9 torr, the true pressure is 760 torr. If the
indicated pressure is 14 mtorr (0.014 torr), the true pressure is 20 mtorr (0.02 torr).
These data were compiled from a variety of sources, and are believed to be reliable, however Ter-
ranova Scientific, Inc.takes no responsibility for errors in the data. If your application is critical,
we suggest you use the services of an independent laboratory to calibrate the gauge and Model
906A controller to your specific application.

VI Maintenance
A. Changing Fuses
The controller contains two fuses. Both fuses are held in the fuse assembly that is part of the pow-
er module located on the back panel of the controller. Follow the instructions below to change a
fuse.
Unplug the line cord from the power entry module at the rear of the 906A; locate the fuse block
immediately below the line cord socket. Press the tab of the fuse assembly and withdraw the fuse
assembly from the power module.
Turn the fuse assembly around so that the fuses are facing you. Check both fuses; replace the
burnt-out fuse with a fuse of the appropriate rating (refer to Specifications section). Reinsert the
fuse assembly into the power module; push it in until the ears click into place.
