These limits are designed to provide reasonable protection againstharmful interference when the equipment is operated in a commercialenvironment. This equipment generates, uses, and can radiate radiofrequency energy and, if not installed and used in accordance with theinstruction manual, may cause harmful interference to radiocommunications. Operation of this equipment in a residential area is likelyto cause harmful interference, in which case the user will be required tocorrect the interference at his own expense. The following techniques canbe used to reduce interference problems:1. Disconnect the unit from its power source to verify that it is or is not thesource of the interference.2. If the equipment is connected to the same outlet as the deviceexperiencing interference, connect the equipment to a different outlet.3. Move the equipment away from the device receiving the interference.4. Reposition the receiving antenna for the device receiving theinterference.5. Try combinations of the above.Product overviewThe controller displays sensor measurements and other data, can transmitanalog and digital signals, and can interact with and control other devicesthrough outputs and relays. Outputs, relays, sensors and sensor modulesare configured and calibrated through the user interface on the front of thecontroller.Figure 1 shows the product components. Components may vary accordingto controller configuration. Contact the manufacturer if parts are damagedor missing.Figure 1 System components1 Controller 3 Digital connectionfitting (optionaldepending oncontroller version.)5 High-voltage barrier2 Strain relief assembly(optional dependingon controller version)4 Network module(optional)6 Sensor modules(optional)Sensors and sensor modulesThe controller accepts up to a maximum of two sensor modules or twodigital sensors (depending on the controller configuration), along with onecommunication module. A single digital sensor and a single sensor modulecan be installed in combination. A variety of sensors can be wired to thesensor modules. Sensor wiring information is given in the specific sensormanuals and in the user instructions for specific modules.Relays, outputs and signalsEnglish 5
