The One Series UUC Feature: Keeping your Safety Secure

Most great ideas or inventions don’t reach perfection overnight; Rome wasn’t built in a day, as they say, and everything from the light bulb to the iPhone has seen improvements and innovations.

Oftentimes, improvements are made through trial and error—other times they come from customer feedback and changing needs. At United Electric Controls, we strive to make the best products of their kind, and often changes and improvements come from those who use them every day: our customers.One Series Safety Transmitter

This was the case for our One Series Safety Transmitter, a unique, groundbreaking product that goes beyond all other safety sensors, solving many of the problems related to the design, operation, maintenance, and modernization of a Safety Instrumented System (SIS).

The One Series Safety Transmitter was carefully designed to meet the requirements outlined in IEC 61508 and simplify SIS design. When first introduced, previous versions of the One Series didn’t include a passcode feature. While it was extremely easy to program and use, the One Series relied on a 2-minute timeout to safeguard critical settings. Many of our customers found the need for additional security in the form of a passcode. When we asked our customers how they managed their passcodes for safekeeping and quick access, a common practice they described was to record the number on the wall next to the instrument, negating the purpose. There certainly must be a better way…

We listened to our customers’ needs and answered accordingly, creating a feature that allows users to get into programming mode after inputting a four-digit passcode. We also designed the One Series Safety Transmitter so that if a user doesn’t know how to save the settings, there is a two minute timeout. Close, but not there yet.

We then found that issues would arise if users lost or forgot their passcode. Thus, the Unique Unlock Code (UUC) feature was created. With the UUC, customers visit a website, which asks specific questions. They must enter their unique Kanban number—similar to a serial number—and the UUC feature performs a mathematical operation delivering a unique four-digit code, which will only unlock their particular instrument; the UUC will always and only work on that one unit. As long as the device is in a secure area, this technology ensures their transmitter is as secure as it is safe.

After all, you can’t have safety without security, and with all of the features of the One Series Safety Transmitter, you have both.
