SYSTEM PERFORMANCE EVALUATION
For initial RUN mode entry (or after any programming alteration), do not use the XPL+ to operate process
control equipment until satisfactory system programming and performance is verified.
1. to enter the RUN mode...
"----" may be displayed briefly while the XPL+ takes measurements and calculates the Reading.
When a Transducer (P004) value is entered for Point # 1 only, the Reading and other data is displayed
continuously. When Transducer values are entered for more than one Point Number, Readings and
other data scroll display for each Point Number.
If an alarm symbol is displayed, the corresponding relay is de-energized.
POINT # ALARM INDICATOR SAM-20# RELAY #
1-10 Hi Alarm 1 1-10
1-10 Lo Alarm 1 11-20
1-10 Hi Hi Alarm 2 1-10
1-10 Lo Lo Alarm 2 11-20
2. to display Readings in
%
(percent of Span, P007) based upon Operation (P001).
OPERATION LEVEL SPACE or DISTANCE
*
Empty to Full = 0 to 100% 100 to 0%
*
Objects close to the transducer face (0%) are not detectable.
3. to observe the mA output value for the Point Number displayed (Auxiliary Reading).
OPERATION LEVEL SPACE or DISTANCE
*
Empty to Full = 4-20 mA 20-4 mA
*
Objects close to the transducer face (4 mA) are not detectable.
4. to observe the
Failsafe Time Left
(time left in percent before failsafe activation).
Each time a valid measurement is made for the Point Number displayed, this value
(Auxiliary Reading) is reset to 100 and begins to fall toward 0 until the next valid
measurement is made.
If the Failsafe Time Left reaches 0, the XPL+ flashes "LOE" in the Reading display.
All associated data is supplied to the Peripheral Communications terminals (42 and 43).
If a BIC-II is connected, refer to TECHNICAL REFERENCE BIC-II Support for message
format and protocol information.
