correct the interference at their expense. The following techniques can be used to reduce
interference problems:
1. Disconnect the equipment from its power source to verify that it is or is not the source of the
interference.
2. If the equipment is connected to the same outlet as the device experiencing 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 the interference.
5. Try combinations of the above.
3.2 Product overview
The controller displays sensor measurements and other data, can transmit analog and digital signals,
and can interact with and control other devices through outputs and relays. Outputs, relays, sensors
and sensor modules are configured and calibrated through the user interface on the front of the
controller.
Figure 1 shows the product components. Components may vary according to controller configuration.
Contact the manufacturer if parts are damaged or missing.
