Unique I AM WORKING™ function
The One Series provides a continuous indication of its health AND the switch output status, both locally and remotely. An LED on the front panel and a discrete logic output signal are used to communicate three states:

• I AM WORKING™ but I Have Not Switched
• I AM WORKING™ and I Have Switched
• I Am Not Working

Signal	Interpretation
I AM WORKING™ output "On" continuously	Normal operation, unit operating properly
I AM WORKING™ output pulsed "On" and "Off"	Beyond set point, unit operating properly
I AM WORKING™ output "Off"	Loss of power or unit inoperable

100% Set point and deadband adjustment
Set point and deadband values are adjustable over the full range span using a convenient, simple to operate, front panel keypad. Access to the programming mode requires a simple, yet tamperproof, keying sequence... It's better than password protection!

Process variable extremes stored in non-volatile memory
System pressure or temperature extremes are retained in the One Series' non- volatile memory, assisting in troubleshooting problems. The One Series captures high and low pressure or temperature extremes constantly.

Unique switch operating mode
The One Series provides four convenient switch operating modes which determine the function of the switch output, deadband, LED status indicator and I AM WORKING™ signal. The desired switch operating mode can be selected from one of four options:

• High Limit Alarm - Close on Rise
• High Limit Shutdown - Open on Rise
• Low Limit Alarm - Close on Fall
• Low Limit Shutdown - Open on Fall
