EZ SYSTEM
HIGH PERFORMANCE, LOW-COST
REMOTE CONTROL
FOR INDUSTRIAL EQUIPMENT

The Cattron EZ Product Group provides industry with a high performance, low cost, Portable Radio Remote Control (PRRC) alternative. The EZ System is an "off-the-shelf" product line that is "EZ" to install, "EZ" to maintain, and "EZ" on your budget. The EZ System is for use on overhead cranes, furnace doors, conveyors, and much more. The EZ does not require an operating license and can be easily installed and ready for use at the job site in a relatively short period of time. All EZ models are microcomputer-based, have high digital message security, and employ both system address and BCH error detection to assure safe, reliable control even in harsh, industrial environments. The EZ system is comprised of two primary components: a receiver/decoder and a choice of either Cattron-Theimeg’s MK or PS controller / transmitters. (See Controller Page for complete information on the MK and PS controllers).

The receiving and decoding hardware and the relay interface are contained within a compact, NEMA 12, IP65 steel enclosure. The receiver/decoder and power supply circuit boards are housed in a sub-chassis which provides EMI shielding and isolation from the output relay interface. The sub-chassis also provides an "EZ" way to change all of the electronics should a repair be required. The decoder makes extensive use of the microcomputer's self-diagnostic capabilities by using a two character display to show system status. The output interface to the machine is handled by plug-in relays rated for heavy industrial loads, both resistive and inductive. Each relay has two screw terminals, an output fuse, and an LED indicator showing when it is energized. A secondary contact on each relay is used by the decoder to sense and verify each of the radio transmitter commands. Should a fault condition be detected, the operator relay and all outputs will be disabled. Automatic Safety Override (ASO) is a safety feature in most Cattron-Theimeg Systems.
