1.0 - Introduction
Thank you for purchasing the new Intellisys™ IQ+ downstream adaptive pressure controller from Nor-Cal Products. Before installing and operating the product,

Nor-Cal Products’ IQ+ pressure controllers are designed for downstream pressure control over a wide range of vacuum control applications. The IQ+ controller
is a self-contained unit that incorporates all control electronics and associated pressure control software. IQ+ controllers are available in Analog, DeviceNet and
Ethernet communication protocols. Buried box versions connect to the valve via a valve cable, while QPA, QPD and QPE controllers are mounted directly on the
valve. Any IQ+ controller, regardless of type, accepts the inputs from one or two pressure gauges as well as communications to the host controller, thus making
it the heart of a pressure control loop.
All models have local open/close switches, LED status lights and RS232 communication.
NOTE: Calls attention to helpful tips about proper
installation, maintenance or use of the controller.
CAUTION: Highlights areas of concern that, if overlooked, could
result in damage to the controller or surrounding equipment.
WARNING: Alerts the installation, operating or maintenance
personnel of hazardous aspects of the controller, which, if
ignored could result in serious personal injury or death.
