UE One Series Seal Oil Skid Cost Reduction

UE ONE SERIES APPLICATION NOTE
One Series electronic switch reliably protects generator with I Am Working^TM

A major electrical infrastructure company designs and manufactures power generation turbines that use natural gas, oil, coal and other fuel technologies. The company has standardized on One Series model 2XLP43 for measuring gage and differential pressure to replace traditional transmitters, UEmechanical switches and mechanical gauges on their seal oil skids.



THE PROBLEM:
The company needed to lower costs, reduce maintenance and provide more reliable hydrogen-cooled generators for their customers worldwide. In order to monitor pressure remotely, provide switch control and be able to instantly view pressure readings, three discrete instruments were needed – a pressure transmitter, a pressure switch and a local gauge. These three instruments were all connected to the same pressure source using the piping tree arrangement to the right.

Counting all of the tubing, elbows, t-fittings and connections to each instrument and the pressure source, potential leak paths quickly became a problem. Not counting block and bleed valves, there were a minimum of 12 threaded connections where the media could leak. The cost of the stainless steel tubing and fittings, the cost of the labor to plumb and leak-test and the maintenance required should clogging or leaking occur were all considered. Adding in the cost of the instrumentation and considering reliability, clearly a better method was needed.

THE SOLUTION:

The company needed a highly reliable instrument that could evaluate and report its own health status and provide the functions of the three instruments while reducing overall costs. The One Series 2XLP model is primarily a smart pressure transmitter with display that includes a programmable electronic switch – switch + gauge + transmitter all-in-one.

All One Series models include a self-diagnostic feature called I Am WorkingTM that monitors several vital instrument functions and reports health status three ways – locally on the digital display and remotely via the 4-20 mA analog and using discrete switch signals.

The One Series’ I Am WorkingTM feature watches for potential faults that could render the device unreliable. Unlike other blind instrumentation, the One Series can report detected faults with its own imbedded software, keypad, watchdog timer, power, switch and sensor. For example, if a clog occurs in an impulse line connected to the pressure sensor, the One Series can detect and report this fault before it becomes a larger problem – an undetected fault. In this case, the display will read “PLUG” while the switch opens (fail safe) and the 4-20 mA output saturates to 24 mA. The PLC evaluating these outputs then initiates an alarm or emergency shutdown, as appropriate.

For the company, the One Series carries worldwide hazardous location approvals and the units of measure are field adjustable, so no matter where in the world these seal oil skids land, the units of measure can be set to the local preference during commissioning. Reliability data is provided by a third-party failure modes and effects diagnostic analysis (FMEDA) report, available on UE’s website.

United Electric Controls Pressure & Temperature Plant Safety Solutions

Whether it’s protecting valuable equipment, processes or your loyal employees, creating a safe work environment is a corporate responsibility. Installing safety instrumentation not only protects critical equipment and processes; it also creates a safe work environment for your employees and a healthier environment for us all.

UE’s One Series digital pressure and temperature switch comes with complete Failure Modes, Effects and Diagnostics Analysis (FMEDA) data from Exida, enabling plant safety personnel to reliably calculate Safety Integrity Levels (SIL). The rugged One Series is installed in the field, at the point of critical monitoring, with response times 5X faster than a transmitter, providing immediate, local shutdown, while streamlining wiring and software. For your plant safety requirements, simplify and improve reliability with the One Series for all critical pressure and temperature shutdown applications.

Direct-Acting Safety Shutdown

The rugged and reliable One Series pressure and One Series temperature switch protects equipment, processes and personnel. It is installed where needed, in the field, with direct-acting on/off digital switching. With 0.1% repeatability combinded with solid-state reliability and on-board diagnostics, the One Series is the clear choice for critical plant safety applications.

Faster Response Time Than A Transmitter

Plant safety requires immediate response to dangerous conditions. The One Series response time is 60 mS, five-times faster than a process transmitter. And, with direct switching capability at the point of critical conditions, it provides an alternative technology to the overreliance on transmitters and central control systems, eliminating the possibility of “Common Mode Failure.”

 

ONE SERIES

Electronic Pressure, DP & Temperature Switches

• Fully adjustable set point and deadband

• 5X faster than a transmitter and 50% less installed cost

• Digital display includes process, status and self-diagnostics

• 2-wire and loop-powered 4-20 mA models available

• Measures gage pressure, differential pressure or temperature

• 0.1% repeatability with temperature compensation

• Provides the functions of a switch, gauge and transmitter

• Ranges to 6000 psi (410 bar), 200 psid (13.8 bar), 1000˚F (538˚C)

On-Board Diagnostics

The One Series continually checks health status for circuit and sensor integrity, providing extra assurance that it stands ready to perform when needed. In addition, it provides a “pulsed” output that can be activated to help distinguish a critical alarm or shutdown signal above the frequent control room “noise” of false trip signals that may be ignored or disabled at operator discretion.

Suitable For SIL2 Applications

Request the "EXIDA" Failure Modes, Effects, Diagnostics Analysis (FMEDA) report from UE covering the One Series, enabling you to calculate the Safety Integrity Level (SIL) for your applications. Also request the SIL Verification Summary report to compare the One Series with generic switches and transmitters. Go to www.ueonline.com for copies of these 3rd party reports.

I AM WORKING (IAW):

The Role of Self-Diagnostics in SIS Applications

All One Series electronic switches include powerful self-diagnostics. Critial functions of the One Series are checked during initialization, and then continuously monitored by the IAW® algorithm. Detected faults are reported using three methods of annunciation:

1. The local digital display provides clear fault indications at a glance
2. Each fail-safe switch will open, providing a remote fault indication
3. On models that include 4-20 mA output, the analog signal will indicate 0, 3.5, 22 or 24 mA, depending on the type of fault.

IAW PROGRAMMING MODE AND RESULTING SWITCH STATES

The fail-safe-open IAW® programming mode provides a predictable annunciation that differentiates between an upset process variable and a detected fault using a single discrete “switch” output.

• When process and instrument conditions are normal, the One Series switch is pulsed, sending out a continuous heartbeat signal that is easily detected by the safety PLC.
 
• When the process variable reaches the programmed set point, the One Series switch will close, indicating that the process is upset but the One Series remains functioning (no faults detected).
 
• If the switch opens, this condition indicates a fault detected by the IAW® self-diagnostics. The reporting scheme also accounts for wiring integrity. If a wire is broken or power is lost, this type of “fault” would also appear as an open switch to the safety PLC.
