Emerson Rosemount 56, Инструкция по эксплуатации

Страница: 12 / 136

Diagnostics: The analyzer continuously monitors itself and the sensor(s) for fault and warning
conditions. A display banner flashes red to indicate a Fault condition and yellow for a
Warning condition to visually alert field personnel. Details and troubleshooting information
for any specific fault or warning can be readily accessed by pressing the INFO key.
Local Languages: Rosemount extends its worldwide reach by offering nine menu languages
– English, French, German, Italian, Spanish, Portuguese, Chinese, Russian and Polish. Every
unit includes user programming menus; calibration routines; faults and warnings; and user
help screens in all nine languages.
Current Outputs: Every unit includes four 4-20 mA or 0-20 mA electrically isolated current
outputs giving the ability to transmit the measurement value and the temperature for both
sensors. Users have wide latitude to assign any measurement value or live diagnostic to any
current output for reporting. Output dampening can be enabled with time constants from 0
to 999 seconds. HART digital communications transmitted via current output 1 is standard
on all units (option code HT).
1.2 Enhanced Features
Process Trending Graphs: High-resolution color graphs of measurement data can be displayed
on-screen to pinpoint process disruptions or measurement problems and to estimate probe
maintenance frequency. The analyzer gives the user the ability to zoom in to a specific
narrow timeframe of process measurements for detailed on-screen evaluation.
Data Logger and Event Logger: Extensive onboard data storage captures measurement
data from both channels every 30 seconds for 30 days for on-screen display or local upload to
a USB 2.0 memory device. 300 significant analyzer events are recorded including start-up
time, calibrations, hold outputs, configurations, alarms, power interruptions, faults, and
more. All process data and events are time/date stamped.
USB 2.0 Data Transfer Port: A USB port is built-in to allow local data transfer of process data
and events using a standard USB memory device. Cleanly formatted EXCEL data is useful for
evaluation of process data on a computer and identification of critical alarm or fault events.
PID Control: Proportional, Integral and Derivative settings allow the analog current outputs
to adjust a control device that has continuous adjustability by acting on process
measurements or temperature. PID is typically used on modulating control devices such as
automated control valves or variable volume pumps. Any current output can be
programmed for PID functions.
Alarm Relay Capabilities: Four Single Pole Double Throw alarm relays are fully assignable
and programmable to trigger alarms upon reaching measurement or diagnostics setpoints
or fault conditions. Further relay settings include TPC, synchronized interval timers and four
specialized timer functions described below. All relays are independently activated. Failsafe
operation and programming of relay default state (normally open or normally closed) is
software selectable.
Timer Functions: Basic TPC (Time Proportional Control) settings are available. Interval
timers set relays by interval time, on-time and recovery time for discrete on/off control
devices based on measurement inputs. In addition, four real-time clock relay functions are
implemented including: bleed and feed, day and time interval timers, delay timer and a flow
totalizer. These advanced timer features support a number of specialized applications that
normally require dedicated timer control devices or DCS programming.
