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 u
It 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.
