Changes or modifications to this equipment not expressly approved by the party responsible for
compliance could void the user's authority to operate the equipment. This equipment has been tested
and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC rules.
These limits are designed to provide reasonable protection against harmful interference when the
equipment is operated in a commercial environment. This equipment generates, uses and can
radiate radio frequency energy and, if not installed and used in accordance with the instruction
manual, may cause harmful interference to radio communications. Operation of this equipment in a
residential area is likely to cause harmful interference, in which case the user will be required to
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 Intended use
The SC4500 controller is intended for use by water treatment professionals who measure multiple

The SC4500 Controller is a 2-channel controller for digital analytical devices (e.g., sensors and
analyzers) and analog sensors that are connected to a digital gateway or expansion module. Refer to
Figure 1.
The controller shows sensor measurements and other data on the display, can transmit analog and
digital signals, and can interact with and control other devices through outputs and relays. Outputs,
relays, sensors and expansion modules are configured and calibrated through the user interface on
the front of the controller or remotely for network connected controllers. The controller connects to
