1 INTRODUCTION
The Models T701, T701H, 701 and 701H Zero Air Generators are an excellent
source of clean, dry air for dilution calibrators. They also may be used as a source of
purge air for permeation tube ovens or burner air for FID analyzers. The T701 and
the T701H (T-Series) include Serial and Ethernet connectivity for remote monitoring
through MODBUS® protocol.
The regenerative, heatless dryer removes water and produces gas with a Dewpoint
of less than -40°C independent of the inlet Dewpoint and assists in the removal of
other gases, greatly increasing the life of the chemical scrubbers.
The units include an oil-free and diaphragm-free pump plus scrubbers to remove
SO2, NO, NO2, O3, H2S, CO (T701 and 701 option), and Hydrocarbons (T701 and
701 option).
Inlet air is pulled into the pump and routed through a pre-cooler and water trap to
remove moisture. The air then passes through the Regenerative Dryer for final
drying and then to the storage tank.
Tank pressure is monitored and maintained at a preset level by cycling the pump
automatically as needed, thereby extending both the pump and scrubber life. Outlet
air then passes through a filter to assure a clean, dry, analytical zero air supply.
These models are an ideal accessory to the Model T700 family of calibrators as a
zero air source for analyzers.
All four models operate the same way, except that the Models 701 and 701H do not
include communication connectivity. Throughout this manual, the zero air generators
will be referred to as the 701X or Model 701X unless specified otherwise.

3.1 Unpacking
CAUTION
TO AVOID PERSONAL INJURY, ALWAYS USE TWO PERSONS TO
LIFT AND CARRY THE 701X.
3.2 Installation
The basic 701X has rubber feet for counter-top use. If the rack mount option was
included in the order, the 701X is supplied with slides and angles for mounting in a
standard 19” RETMA rack.
In order to ensure safe operation of the 701X, the following steps must be taken
prior to installation for proper venting, access, weight support, and operation:
1. At least 6” (150 mm) clearance at the rear of the instrument.
2. At least 3” (75 mm) at each side.
3. Adequate support for the weight (Table 2-1).
4. Access at the rear for making the pneumatic and electrical connections.
5. Access at the front.
6. Operate the 701X with the cover on.
WARNING
ELECTRICAL SHOCK HAZARD
• High Voltages are present inside the instrument.
• Ensure that the power cord being used is capable of carrying the
power rating of the instrument (see Specifications Table 2-1)
• Power connection must have functioning ground connection.
• Ensure that installation provides access to disconnect power from
the instrument.
• Do not defeat the ground wire on power plug.
• Turn off power before disconnecting or
connecting electrical subassemblies.
• Do not operate with cover off.
Attach power cord to AC receptacle of instrument, and plug it into a power outlet
capable of carrying at least the rated current at your AC voltage range; also ensure
that it is equipped with a functioning earth ground.
ZERO AIR OUT Connect the AIR OUT port of the 701X to the
(1/4” swage type INLET fitting of the Model 700 Calibrator with
bulkhead union) clean 1/4” TFE tubing
Keep this line as short as possible to minimize
pressure drops.
3.5 Power-Up
Turn on the front panel POWER SWITCH (Figure 3-2).
• The front panel POWER light should come on.
• The cooling fan should start immediately.
• The compressor should start after a few seconds delay. The delay is to allow
the control board to initialize and boot up.
• After 30 to 60 seconds, the front panel pressure gauge should read 30 psig.
• The 701X is now producing clean dry air.
NOTE
If the 701X has been unused for several days, it may take 30-60 minutes to
achieve final purity and dryness.
NOTE
The 701X zero air has a 20 (T701, 701)/30 (T701H, 701H) liter/minute output
restriction. It must be connected to a Model 700 or similar calibrator to
restrict the zero air flow for lesser flow rates.
For a final clean-up, the dry, regulated air enters the specific scrubbers as follows:
1. The Hydrocarbon scrubber (option in the T701 and 701, which includes the CO
scrubber) where Hydrocarbons and CO are catalytically converted to CO2 and
water.
2. The NO scrubber where NO is oxidized to NO2.
3. The activated charcoal scrubber where the NO2 is absorbed.
4. The CO scrubber (option in the T701 and 701), where CO is catalytically oxidized
to CO2.
5. The clean dry air passes through a fine particulate filter and leaves the 701X
through the rear panel bulkhead union (Zero Air Out).
When air usage is high, the compressor may run continuously. When air usage is
low, the pressure switch turns the compressor off until the storage tank pressure
drops to 45 psig, and then turns the compressor on again.
NOTE
It is not necessary to turn off the 701X when the air usage is low.
4.2 Components
This section describes the main components of the instrument and their functions.
4.2.1 Compressor
The compressor is a dual-cylinder oscillating piston type driven by a split capacitor
AC motor. The compressor is dry; that is, there are no lubricants which can
contaminate the compressed air. The pistons are sealed by flexible TFE piston rings,
and after a short run-in period to seat the rings, should last for years. There are no
diaphragms.
The compressor is mounted on a sub-plate which is supported on four tuned
vibration isolators.
The operation cycle has been preset at the factory and is not adjustable.
4.2.14 NO Scrubber
The NO scrubber uses Purafil® to oxidize NO to NO2. Purafil® has a finite life and we
recommend that it be replaced (Section 6.5) annually or sooner if the level of NO in
the air is high.
4.2.17 Controller
WARNING
DANGEROUS VOLTAGES EXIST ON THE CONTROL BOARD.
All functions of the 701X are managed by the Control board (Figure 4-2). The
Control board provides connections for all switched and non-switched AC and DC
components, AC/DC input, front panel indicators, communications board (T-Series
only) and the front panel power switch/circuit breaker.
Switched DC components include the Regenerative Dryer valve, water drain valve,
and the relief valve. Switched AC components include the pump and HC Scrubber.
Provision for 120V/240V AC power is via a jumper plug (J5).
Non-switched components include the CO scrubber and fan.
All electrical connections are made by quick release connectors to aid in servicing.
Additionally, the tank pressure, output pressure and Dewpoint connections are made
to the control board with flexible tubing. Refer to Figure 4-2 for the layout and to
Appendix B for the interconnect drawing.
The 701X Control PCB is microcontroller based, and provides the following
functions:
• Cycles the four-way valve of the Regenerative Dryer.
• Cycles the water drain solenoid valve.
• Starts and stops the compressor in response to the pressure sensor. This
function includes cycling the Regenerative Dryer four-way valve and
momentarily opening the water drain solenoid valve before starting the
compressor. This momentarily reduces the pressure at the compressor outlet
to facilitate compressor starting.
• MODBUS® communication (T-Series only) via the Rear Panel Connectors to
remotely display instrument’s parameters.
• Monitors and regulates the HC Scrubber Temperature.
LED D13 (Figure 4-2) flashes at 1 second intervals as an indication that the
controller is functioning, and a watchdog timer is enabled to prevent any power line
disturbances from halting the processor.
To set the instrument for use with terminals (DTE), modems (DCE) and computers
(which can be either), use the switch labeled DCE DTE mounted below the RS232
ports on the rear panel to select one of these two data devices. This switch
exchanges the Receive and Transmit lines on RS-232 emulating a cross-over or
null-modem cable.
NOTE
2. Slide the rear panel Ethernet RS-232 switch down toward the RS232 port.
3. Check the activity indicators labeled Rx and Tx above the RS232 port: both the
red and the green LED should be lit.
• If the LEDs are not lit, change the DTE DCE switch to its other mode.
• If both LEDs are still not lit, ensure that the cable is properly constructed.
Received from the factory, the unit is set up to emulate an RS-232 DCE device as
follows:
• RS-232: RS-232 (fixed) DB-9 male connector
• Baud rate: 57600 bits per second
• Data Bits: 8 data bits with 1 stop bit
• Parity: Even
5.2 Ethernet
When using the Ethernet interface, the instrument can be connected to any standard
10BaseT or 100BaseT Ethernet network via low-cost network hubs, switches or
routers. The T701/T701H is DHCP-enabled by default (Section 5.2.2). This allows
the instrument to be connected to a network or router with a DHCP server, which
automatically assigns an IP address for the instrument. This configuration is useful
for quickly getting an instrument up and running on a network. However, because
DHCP can reset the IP address automatically, it is recommended that the manual
method be used for Ethernet configuration (Section 5.2.1) so that the IP address
remains static.
The Ethernet connector has two LEDs that are on the connector itself, indicating its
current operating status.

12. Click the Close button to close the dialog box and return to the main window.
2. Click the Search icon. After a moment a list of instruments on the network will
be displayed. The instrument should be listed as an XPORT-IAP type device.
3. Double-click on the device in the right-hand section of the DeviceInstaller
window; a list of configuration parameters will be shown, including the IP
Address. If multiple devices are shown, the correct one can be determined by
matching the Hardware Address shown with the address printed on the label of
the Ethernet module in the instrument. Remove the instrument cover or lower
the rear panel to find this address.

6.2 Cleaning
1. Occasionally, depending upon the local conditions, check the inside of the 701X
for excessive dirt or dust.
2. Particularly, check the cooling fan, cooling coil and compressor fan inlet.
3. Remove any dirt or dust with a vacuum cleaner.
Do not use an air jet. This will only redistribute the dirt and will not remove it.
WARNING
THERE ARE HIGH VOLTAGES PRESENT WHILE THE 701X IS
PLUGGED IN.
CAUTION
DO NOT LOOSEN ANY TUBING CONNECTION WHILE THE
701X IS RUNNING.
CAUTION
BEFORE WORKING ON THE 701X PLUMBING TURN OFF THE
701X, WAIT FOR THE PRESSURE GAUGE TO READ ZERO.
(THIS MAY REQUIRE THAT YOU LOOSEN THE REAR PANEL
BULKHEAD UNION TO ALLOW THE AIR TO BLEED AWAY.)
WARNING
EVEN THOUGH THE FRONT PANEL POWER SWITCH IS OFF,
THERE IS LINE VOLTAGE PRESENT AT THE POWER ENTRY
TERMINALS AND POWER SWITCH TERMINALS FOR ADDED
SAFETY, REMOVE THE POWER CORD FROM THE REAR

7. Remove the pad from the top of the canister.
8. Pour out the charcoal and dispose of it properly.
9. Refill the canister with fresh charcoal, up to 3/8” to 1/4” from the top. Rap the
sides of the canister gently to settle the charcoal and add more as necessary.
10. Replace the pad on top of the charcoal.
11. Wipe any charcoal dust from the top edge of the canister. This is the surface
which seals against the gasket.
12. Check that the gasket is in place in the cap.
13. Replace the cap and tighten it “hand-tight”.
14. Reconnect the lower 1/4” tube connection.
15. Reattach the canister with the fastening strap.
16. Reconnect the upper 1/4” tube.
17. Enable “maintenance mode” (Section 6.6) which will bypass the Dewpoint
warnings during scrubber drying.
18. After the compressor is turned on, it may be wise to check the scrubber for leaks
using a commercial soap solution leak finder.
19. Place the instrument in Maintenance Mode to dry out scrubber (Section 6.6).
NOTE
After replacing the material in these scrubbers it can take up to 48 hours
for the material to dry out before the 701X is functioning optimally.
2. With a wrench, remove the inlet and outlet tubing and the two unions from the top
of the scrubber cartridge.
3. Remove the four screws to remove the scrubber.
4. Pick out the retaining screens.
5. Shake out the catalyst beads and dispose. No special disposal methods
required.
6. Pour in new catalyst to 1/2” from the top of the bores. Tap the cartridge sides
gently to settle the beads and top up to the 1/2” level.
7. Replace the retainer screens.
8. Replace the TFE tape on the two unions and replace the unions in the cartridge.
9. Reassemble the scrubber, replace it in the chassis and reconnect the tubing and
receptacle.
10. Turn on the 701X and leak check using soap solution.
CAUTION
WAIT FOR THE SCRUBBER TO COOL. THE SCRUBBER CASING
AND THE COPPER COOLING COIL WILL BE VERY HOT.
6. Remove the four screws holding the scrubber, under the chassis.
7. Lift out the scrubber.
8. Install a new Teledyne API-supplied scrubber (these are purged at the factory).
9. Screw it down.
10. Attach and tighten the pneumatic connections.
CAUTION
ENSURE THAT THE COPPER COOLING COIL IS NOT TOUCHING
ANY WIRE OR CABLE.
14. Connect a millivolt meter to J17 (labeled “Thermal Couple” in Figure 4-2) on the
temperature controller.
Observe that the Heater Relay LED (D8) starts blinking at 11.2 mV (300ºC) and
that the thermocouple voltage holds steady.
15. When all traces of water have disappeared from the 701X output, the output may
be reconnected to the analyzers.
15. Place two new clean retainer pads on top of the molecular sieve. Push the pad
1/8” into the column.
16. Change the four o-rings in the circular grooves in the upper and lower manifolds.
17. Place the bottom of the columns with two pads in the circular grooves in the
lower manifold. Ensure that they are in the grooves and not caught up on the
edge.
18. Wipe the ends of the columns. These are the surfaces which seal against the
o-rings.
19. Place the upper manifold (new if replacing the shuttle valve, Section 6.11) on top
of the two columns. Ensure that the columns are in the grooves. (Wiggle the
columns sideways to ensure that the columns are seated in the grooves.)
20. Replace the nuts and lock-washers on the three tie rods BUT DO NOT TIGHTEN
THEM.
21. Push down hard in the center of the upper manifold with one hand and finger-
tighten the nuts until you feel a soft resistance.
22. With a wrench, tighten each nut in turn, 1/2 turn at a time. This will ensure that all
the nuts are tightened evenly. If the nuts are tightened unevenly, the column o-
rings may not seal and you may cause damage to the sealing surfaces.
23. Examine the fit of the columns in the manifold groove one more time.
24. Re-attach the 4-way valve bracket.
25. Replace the dryer in the 701X chassis and tighten the four captive screws.
26. Reconnect the two pneumatic fittings and the valve power cord.
27. Plug in and turn on the 701X.
28. Using soap solution, check the dryer for leaks.
If no leaks are detected, the 701X is ready for operation.
