Additional Features and Data as from UE Controls:
THEORY OF OPERATION and FEATURES
The One Series electronic switch product line is based on an all-solid-state electronic module that incorporates a microprocessor. The combination of features like no moving parts and IAW self-diagnostics provide a highly reliable, accurate and repeatable monitor for detecting pressure and temperature thresholds and, once reached, can make intelligent switch decisions based on retained settings and current conditions. Where a mechanical device has no way of determining its readiness , the One Series monitors its own health and reports it locally. This IAW (I Am Working) feature provides a solution to the blind device issue common with mechanical apparatus. You will always know the health status of the One Series. The One Series is also very rugged, featuring a Type 4X, weather-tight enclosure suitable for harsh environments and hazardous
(Class I, Division 2) locations. The 0.5% accuracy rating is maintained over a very wide -40 C - (+70 C) operating range using active temperature compensation. Repeatability rivals that of a process transmitter, with a 0.1% of full range rating. The set point and deadband (hysteresis) of the switch is fully programmable over the entire range of the sensor.
The One Series features a large, easy-to-read display, showing the process condition and the status of the instrument. (See Display Features for a complete description.) Set point, deadband and minimum/maximum process values can be easily accessed from the front of the unit while in operation. Programming and interrogating the One Series is done through two buttons on the faceplate.
DISPLAY FEATURES AND DIAGNOSTICS
The One Series features a large, easy to read LCD display. It is used for three main purposes: process indication, programming of key features and switch status/troubleshooting.
When the process goes beyond the set point, the display will begin to flash, alternating between the process value and SW1 . The display will continue to flash until the process has returned to a value beyond the deadband, at which point the display will revert to normal operation and process value display.
The One Series also contains UE s patented IAW diagnostic software. On a continuous basis, the One Series is checking itself for proper operation, and letting you know locally that things are OK using animated arrows on the display. For remote assurance, the output can be set up for 3-state operation,allowing the host device to detect normal, tripped, and fault conditions (see Key Programming Features, page 7 for a full description of the 3-state operation). IAW watches over many possible problems, both within itself and in the overall system (a list of the various parameters is outlined in the chart under Fault Codes, page 10). In the event of a fault condition, the One Series will attempt to display the problem and provide remote electrical
indication. In the case of certain micro-controller faults, the revolving arrow may freeze or go out, indicating that a failure exists.
The One Series has other advanced features:
When the Plugged Port feature is enabled, the One Series will watch for process conditions which could be evidence of a plugged sensing port or
an accidentally-closed instrument valve, and alert the user to potential problems.
The switch output can be configured for either automatic reset or latching, requiring the user to manually acknowledge the alarm.
