SYSTEM PERFORMANCE EVALUATION
For initial RUN mode entry (or after any programming alteration), do not use the DPL+ 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 DPL+ 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 Point #’s 1 & 2, Readings and
other data are displayed alternately. When a Point # 3 Operation is entered (difference or average),
the Point # 1, 2 and 3 displays scroll sequentially.
If an alarm symbol is displayed, the corresponding relay is de-energized.
POINT # ALARM INDICATOR RELAY #
1 Hi Alarm 1
1 Lo Alarm 2
2 Hi Alarm 3
2 Lo Alarm 4
2. to display Readings in

Objects close to the transducer face (0%) are not detectable.
3. to observe the mA output value for the Point Number displayed (Auxiliary Reading).

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 DPL+ flashes "LOE" in the Reading display.
All associated data is supplied to the Peripheral Communications terminals (27 and 28). If a BIC-II is
connected, refer to BIC-II Support for message format and protocol information.
