3.0 - Unpacking and Installation
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. 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.
NOTE: Do not discard the packing materials until the product has been inspected to your satisfaction.
Installation
To allow for proper ventilation, make sure that at least 3 inches of unobstructed space is available adjacent to all perforated
sides of the IQ+ controller. Then, complete all cable connections as required referring to the figures and pin assignment
tables in Sections 3.1 – 3.3 of this manual. A list of pre-manufactured cable assemblies available from Nor-Cal Products
can be found in Appendix I.
CAUTION: The optional +15V and –15V power supply pins of the IQ+ gauge connector are power sources
that are intended to power the optional system pressure gauge(s). It can supply a maximum of 1500 mA. Do
not use for any other purpose and do not connect to the tool main 15V supply as the two supplies would
interfere with each other.
NOTE: Low voltage controller models do not have a power on/off switch. Consider installing an external
power on/off switch between the DC power supply and the controller to allow for de-energizing the unit
without having to disconnect the cable.
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, for buried box IQ+ controllers,
connect the controller to the valve and then to an appropriate +24DC, 4A power source. For all valve IQ+ controllers simply
apply the +24DC, 4A power source. The butterfly valves will complete a 30 second valve initialization sequence ... the valve will
stop in the open positoin. For soft shut (TSS) valves and pendulum (TPV) valves press the open and close buttons at the same
time. The valves will begin the valve initialization sequence like the butterfly valve. The length of time to complete this sequence
will vary from 40-60 seconds depending upon the type and size of valve. The valve will complete a 30-second initialization
sequence during which the valve plate will cycle back-and-forth a few times while the OPEN/CLOSE LEDs blink in an alternat-
ing pattern. The valve will eventually stop in the open position. Further verification of the system can be done by toggling the
“OPEN / CLOSE” switch (if available) on the controller front panel. If the valve does not operate as described please contact Nor-
Cal Technical Support.
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 whenever human physical intervention is required on all of its control valves.
