NOTE: Calls attention to helpful tips about proper
installation, maintenance or use of the valve.
CAUTION: Highlights areas of concern that, if overlooked, could
result in damage to the valve or surrounding equipment.
WARNING: Alerts the installation, operating or maintenance
personnel of hazardous aspects of the valve, which, if
ignored could result in serious personal injury or death.
Thank you for purchasing a new Intellisys™ Tss SoftShut™ throttling gate valve from Nor-Cal Products. Before installing and operating the product,
please read this manual thoroughly as it contains critical hook-up and operating tips. If you encounter any problems, or if you have any questions,
please contact our Intellisys Customer Service Support at [phone] or visit our web site at www.n-c.com.
Nor-Cal Products’ TSS Softshut gate valves are designed for foreline isolation and downstream pressure control over a wide range of vacuum control applications
in conjunction with an APC-series buried box or IQ-series on-valve controller module. The TSS Valve cannot be operated by other manufacturers’ valve
controllers. All interface and communications connections are made directly to the controller module that, in turn, provides power and position signals to the
valve motor. Used with a controller module and the inputs from one or two pressure gauges the TSS-series gate valve forms an integral part of a complete
downstream pressure control system.
Important Personnel Safety and Product Protection Information
Throughout this manual, information that is of particular importance to the installation, the safety of
operating personnel and the protection of equipment are highlighted by the following three symbols.
The WARNING symbol is also used on the equipment wherever necessary.

Unpacking: Inspect the shipping box before unpacking. Any damage should
be reported to Nor-Cal Products or directly to the transportation carrier.
Carefully remove the product from the box and visually inspect it for damage.
NOTE: Do not discard the packing materials until the
product has been inspected to your satisfaction.
If return of the product to Nor-Cal Products should become necessary, please
contact Intellisys Customer Service to obtain a Return Materials Authorization
(RMA) Number.
Pre-Installation Functionality Check: Nor-Cal Products carefully ensures
that every product shipped is in perfect working condition. However, it is still
a good idea to quickly check the functionality of the unit prior to installation
into the vacuum system. To do so, connect the TSS-series valve to a Nor-Cal
Products APC-series controller (or directly to an appropriate DC power source
in case of an IQA or IQD-series valve). On the controller, press OPEN-OPEN-
CLOSE-CLOSE to start the valve homing sequence. The valve will complete
a 30-to-40-second initialization sequence during which the valve plate will
cycle back-and-forth a few times while the controller module OPEN/CLOSE
LEDs blink in an alternating pattern. The valve will eventually stop in the open
position.
WARNING: When working with or troubleshooting Nor-Cal
APC products extreme care must be taken to avoid putting bodily
parts in or near the valve gate mechanism or other moving parts.
These may move suddenly and unexpectedly, and many of them
are driven with sufficient force so as to cause significant harm and
possibly even dismemberment. Nor-Cal Products recommends
that a lock-out and tag-out procedure be strictly followed when
ever human physical intervention is required on all of its control
valves..
Further verification of the system can be done by toggling the “OPEN /
CLOSE” switch on the controller front/top panel. If the valve does not operate
as expected please contact Nor-Cal technical support.
Valve Installation: Install the TSS-series valve in your vacuum system using
the appropriate hardware and cables. To allow for proper ventilation and
access, make sure that at least 3” of unobstructed space is available adjacent
to all perforated sides when installing a IQA or IQD-series valve, and that at
least 3.5 inches of space is reserved above the top of the valve to allow for
cable connector hoods. A complete list of installation hardware and cables
assemblies available from Nor-Cal Products can be found in Appendices I
and II.
NOTE: Refer to the appropriate section of the Adaptive Pressure
Controller Operating Manual (APC-OP-LIT) for more details about
cable connections and pin-outs.
Once the valve is installed in the system, the approximate valve gate position
can be determined by referring to the black circular disk fastened to the rotary
shaft on the red gear box. The ut symbol represents an open valve,
whereas a closed valve is represented by the uIt symbol. Both symbols
are referenced to the small triangular mark on the gear box
3.0 - Unpacking and Installation
Heating the Valves
Heating the Valves: Sometimes it is necessary to heat the TSS-series valve
to prevent process contamination from condensing on the internal valve sur-
faces. The valve can be ordered as a heated valve, in which case the heater is
laminated to the exterior of the valve and the entire valve body is encased in a
hard insulated shell. As an alternative, Nor-Cal can offer retrofit heater jackets
that can be installed in the field. These heater jackets are available in both PID
and Thermostatically controlled versions, custom fit for each size valve. Please
call Nor-Cal Intellisys Customer Support for heater jacket and related acces-
sories ordering information.

4.0 - Theory of Operation
The TSS-series valve is designed for downstream pressure control. As such,
it is one of four important components in a pressure control system. The other
three essential components include a host system computer, a controller mod-
ule (APC, IQA or IQD) and one or two vacuum gauges, such as a Capacitance
Diaphragm Gauge (CDG). Most manufacturers’ vacuum gauges can be used
to provide the vacuum measurement signal, provided they have a voltage out-
put proportional to pressure. Please see Appedix I for summarized connection
information. More complete signal pin-out and communications information
can be found in Nor-Cal Adaptive Pressure Controller Operating Manual, part
# APC-OP-LIT
FIGURE 4.1 – TYPICAL INSTALLATION AND CONFIGURATION OF A
TSS-SERIES CONTROL VALVE (DASHED LINES REPRESENT TSS-IQA
OR IQD INSTALLATION)
Initialization Sequence: Before typical pressure or position control can
begin, the TSS-series valve needs to complete an initialization sequence that
lasts for approximately 30-40 seconds, depending on the size and start-
ing position of the valve. The primary purpose for this operation is for the
controller to determine the fully open and closed points, as well as for certain
motor and position calibration steps to occur. When the valve controller is
first powered on, the amber FAULT light will be illuminated and the OPEN/
CLOSE LEDs will blink in an alternating fashion. To start the initialization
sequence, press OPEN-OPEN-CLOSE-CLOSE on the controller panel. Once
the initialization sequence is complete, the valve will move to the fully open
position and the green OPEN LED will illuminate.

Normal Operation: After the initialization sequence is complete normal operation of the TSS control
valve is possible. There are two primary modes of operation, a) position control mode and b) pressure
control mode.
In Position control mode the valve will move to any position in its range based on a position set-point
command from the host. The valve will remain in that position until instructed to do otherwise. Position
control mode can be useful in certain cases where pre-determined amount of baffling or throttling is
necessary.
Pressure control mode, on the other hand, is used whenever control to a specific system pressure level is
desired. The host provides the set-point value and the throttle valve strives to achieve that set point as
quickly as possible. During pressure control mode, external perturbations such as flow changes and
plasma events will automatically be compensated for by the APC, IQA or IQD controller module so that
the pressure set-point is maintained.

Tuning: All Nor-Cal controller modules contain an Adaptive Pressure Control
Algorithm that has been designed to work over a wide range of flow- and
pressure-combinations. There are therefore no “learn modes” to execute, nor
does the user have to set PID parameters. In some instances, however, vacu-
um system design may affect the closed loop pressure control time constants.
As a result, pressure control performance may at times be affected. If satisfac-
tory pressure control cannot be achieved with the Adaptive Pressure Control
Algorithm, please contact Nor-Cal Products Intellisys Customer Support.

5.0 - Product Support
TSS Valve Service and Maintenance Intervals: The TSS valve was designed for long life and high reliability and, in clean environments, have been shown to
operate with a MTBF well in excess of a year of typical vacuum processing. Process chemistry, temperature and type of use do however affect the moving parts
of the valve and hence the necessary service interval. Therefore Nor-Cal Products recommends inspecting and servicing the valve on a regular basis to avoid
unexpected failures. Please refer to Table 5.1 for recommendations on TSS-series preventive maintenance and service.
TABLE 5.1 – RECOMMENDED TSS-SERIES PREVENTIVE MAINTENANCE ACTIONS AND INTERVALS
RECOMMENDED ACTION PURPOSE / WHAT TO LOOK FOR RECOMMENDED INTERVAL
With valve still installed in system and operating
normally, visually inspect the rotary indicator disk and
drive assembly.
Rotary position indicator disk may give early indica-
tions of mechanism hang-ups, especially if observed
movement is more erratic than typical. The motor
drive assembly may move back-and-forth slightly if
too much friction is present in the valve assembly
– also an early indicator of mechanism hang-ups
Weekly to monthly, initially, until a process specific service
interval has been determined for the valve.
Remove TSS control valve from system for visual inspec-
tion.
Look for process build-up. Also, inspect for areas
showing scratches in or near gate tracks. The latter
can be a sign of gate misalignment or roller wear.
Monthly, initially, until a process specific service interval has
been determined for the valve.
With controller power OFF, remove TSS motor drive
unit and inspect Oldham coupling disk (valve body can
remain installed in vacuum system)
Inspect for Oldham coupling disk wear and fit. The
presence of a whitish powder indicates disk wear.
Also, the disk should fit snugly on each of the two
hubs, and remain on even when upside down.
After 3 months of use, and then every 3 months, until a
process specific service interval has been determined.
Remove TSS control valve from system and perform leak
check across the seat and/or to atmosphere.
Determine loss of seal integrity due to process
buildup or degradation due to chemical or thermal
attack. All new valves are tested to 1  10-9 atm•scc/
sec He (Viton® seals)
Every 6 months, unless extremely high temperatures or
highly aggressive chemicals are used.
Disassemble valve body to access gate assembly, bear-
ings and O-rings. Replace seals, re-lubricate and clean
as necessary
High vacuum grease used in bearings and seals can
gradually disappear due to evaporation or chemical
attack. The O-ring seals can wear or crack due to
contamination, chemical attack or excessive heat.
Process residue can accumulate in gate tracks and
rollers, either leading to increased particle genera-
tion or ultimate seizing of the assembly.
In heated or chemically aggressive applications:
after 6 months of continuous use.
In low temperature and inert applications: after 12
months of continuous use. Or, whenever a leak is found via
leak detection.

5.3 - Troubleshooting
Some basic troubleshooting can be done by the user referring to the instructions and suggestions below. Table 5.3 describes possible
symptoms and recommended actions.
TABLE 5.3 – POSSIBLE FAILURE MODES AND RECOMMENDED ACTIONS
Symptom Possible Causes Recommended Action
The TSS valve does not appear to turn on or oper-
ate.
The TSS is not connected to the controller module
(standard TSS models only)
Check to make sure the controller-to-valve cable
is connected at both ends, using the correct con-
nectors.
The controller-to-valve cable is faulty (standard
TSS models only) Try another TBV-CRD-XX cable.
The controller module is not on, or is faulty. Check controller module and refer to appropriate
controller Operating Manual
The Oldham coupling is broken Turn off controller power. Remove motor drive to
inspect Oldham coupling
The TSS appears to operate but pressure- or posi-
tion control is inconsistent and poor
The valve gate is jammed or partially jammed in
the valve bore.
Turn off controller power and remove the motor
drive from the gearbox. Attempt to move
the gearbox input shaft by hand. If binding is
observed, remove valve from system to deter-
mine the root cause. Clean off process residue as
necessary using a non-abrasive method. If dam-
aged parts are found, contact Nor-Cal Intellisys
Customer Support
The Oldham coupling disk is worn or cracked
Turn off controller power. Remove drive unit from
gearbox. Replace the Oldham coupling disk as
necessary.
A whining or buzzing sound is heard from the TSS
motor drive
The Oldham coupling disk, or possibly hubs, is
loose or worn and a harmonic resonance point has
been excited
Turn off controller power. Remove drive unit from
gearbox. Replace the Oldham coupling disk as
necessary. If problem persists, contact Nor-Cal
Intellisys Customer Support.
The controller motor control coefficients have
been corrupted.
Turn off controller power. Turn back on and allow
initialization sequence to complete
The wrong controller is being used.
Note model and serial number of valve and con-
troller and contact Nor-Cal Intellisys Customer
Support
The motor and valve shaft rotate continuously in
one direction without stopping and without mov-
ing the valve gate
The square key between the rotary shaft and
gearbox is missing or broken.
Remove the rotary indicator disk, spacer and
screw. Remove the four screws holding the gear-
box to the valve. Slide off gearbox / motor assem-
bly from rotary shaft and inspect key and shaft
keyway. Replace items as necessary.
The gate actuation arm is broken or otherwise
decoupled.
Turn off vacuum system. Open the bonnet cover
by loosening the bolts on back plate. Look inside
to inspect short gate arm that links the rotary
shaft to the gate and carriage mechanism. NOTE:
It is impossible to move or turn the shaft with
the gearbox attached. If manual operation is
required, then removal of the gearbox is neces-
sary (see step above).
The valve has developed a leak to atmosphere
along the valve shaft
O-ring damage and/or loss of vacuum grease can
cause this
Follow steps above to open bonnet cover AND
remove gear head. Remove the square and plates
found under the gearbox, and remove the short
gate arm attached to the shaft. Pull shaft out
from bearing and seal cavity (this may require a
tool (Please contact Nor-Cal Intellisys Customer
Support to obtain instructions). Visually inspect
the seal, relubricate or replace as necessary.
