Item
No. Item Name Description
————————————————————————————————————————
451 PLOG PRESSURE HIGH This item indicates if a PLog high pressure alarm was
generated. During a PLog sample (Item 401), if the
measurement for item 420 (PLog GAS PRESSURE) is greater
than the value entered at item 455 (PLog PRESS HILIM), an
alarm is initiated and is indicated by placing dots on the LCD
and ‘11111111’ at item 451. ‘00000000’ at item 451 indicates
there is no PLog pressure high alarm. The alarm indicators
will remain active until manually cleared (by software) or
automatically when RBX is enabled. The PLog Pressure High
Limit value (item 455) is user selectable and is normally set
somewhere between 50 and 100% of transducer range.
Default = 00000000
452 PLOG PRESSURE LOW This item indicates if a PLog low pressure alarm was
generated. During a PLog sample (Item 401), if the
measurement for item 420 (PLog GAS PRESSURE) is a value
less than the value entered at item 456 (PLogPRESS LOLIM),
an alarm is initiated and is indicated by placing dots on the
LCD and ‘11111111’ at item 452. ‘00000000’ at item 452
indicates there is no PLog pressure low alarm. The alarm
indicators will remain active until manually cleared (by
software) or automatically when RBX is enabled. The PLog
Pressure Low Limit value (item 456) is user selectable and is
normally set somewhere between 0 and 50% of transducer
range.
Default = 00000000
455 PLOG PRESS HILIM High limit for PLog pressure, initiates alarm (item 451), if
exceeded by item 420.
Default = 099999.99
456 PLOG PRESS LOLIM Low limit for PLog pressure, initiates alarm (item 452), if
higher than item 420.
Default = 0.00
459 PLOG PRESS DEADBAND A hysteresis band that provides a buffer below the PLog
Pressure Hi limit (item 455) and above the PLog Pressure Lo
limit (item 456) when alarms are automatically cleared by
RBX operation. The user-specified value determines the
magnitude of the band. The PLog pressure measurement (item
420) must pass completely through the dead band before the
pressure alarm is automatically cleared.
Default = 5.00 PSIG
