OUTPTG

Output Gain. The Output Gain parameter allows the user to adjust the

 

actual 20 milliamp (span) output value as referenced to the MST2000

 

displayed full scale value. The output gain parameter is displayed and

 

stored in memory as a gain multiplier. After the EDIT key is pressed, the

 

edit menu displays the actual multiplier value and the microprocessor

 

sets the output to the 20.000 milliamp value. The user then uses the

 

INC and DEC keys to adjust the desired full scale milliamps. Use the

 

MODE key to adjust the cursor position (i.e., x D1, x D01, x D001 etc.)

 

to change the gain multiplier in different increments. The available

 

range is 0.8000 to 1.1000. (Approximately 16.5 to 20.5 milliamp

 

adjustment range). The factory default is as set by the factory during

 

initial system calibration.

 

þNOTE: The minimum and maximum output current range is 3.9 milliamps

 

and 20.5 milliamps (3.8 milliamps is reserved for fault ‘low’ current and

 

21.0 milliamps is reserved for fault ‘high’ current).

 

þNote: If HART® com mu ni ca tions are en abled, the min i mum cur rent is lim-

 

ited to 4.0 milliamps.

This is a factory default setting determined during calibration. It should be recorded by the user in the event it will be necessary to restore the Output Gain to the original value. This setting is also recorded on a label located under the cover of the MST2000.

AVGFAC

Averaging Factor. The Averaging Factor controls the digital filtering 1= No Filtering level (damping) of the displayed pressure value (and the 4-20 milliamp

output). The average factor parameter controls the size (depth) of the digital FILO (first in – last out) filter algorithm. Available range is 1 to 10. The average factor does not affect the inherent update rate of the LCD or 4-20 milliamp output (approximately two times per second) except during power up initialization when the FILO registers are first being loaded.

DEFDSP

Default Display. The Default Display parameter assignment selects the LCD display mode after power up and initialization. Available assignments are:

Eng lish Unit Ver sion: 0 = INWC (pri mary vari able), 1 = SCFM, 2 = ACFM, 3 = LBHR or 4 = SCAN. Se lecting SCAN will cause the dis play to se quence through the cal cu lated vari ables at 4 sec ond in ter vals.

Metric Unit Version: 0 = MMWC (primary variable), 1 = NM3-HR, 2 = M3-HR, 3 = KG-HR or 4 = SCAN. Se lecting SCAN will cause the dis play to sequence through the cal cu lated vari ables at 4 sec ond in ter vals.

0 = INWC for English.

0 = MMWC for Metric.

DSPRES

aLARMS

Display Resolution. The Display Resolution parameter assignment

3 = X.XXX

controls the number of digits that are displayed to the right of the

 

decimal. The display resolution can be set as fol lows:

 

Eng lish Unit Ver sion: From 1 to 4 Digits to the right of the dec i mal. Met ric

 

Unit Ver sion: From 1 to 3 Digits to the right of the dec i mal.

 

The MST2000 has multiple alarm features. Alarms are available for

0 = Alarms Disabled

4-20 milliamp limit checks (under-range and over-range), RTD faults,

 

external 4-20 milliamp PCB communication failures and internal

 

hardware circuit faults. Alarms are enabled and disabled by setting the

 

individual binary bits in the ALARM WORD register to a ‘1’ or ‘0’

 

respectively. Since the individual binary bits cannot be displayed on the

 

LCD, the user must input the decimal word equivalent representing the

 

enabled and disabled bits. The individual alarm bit assignments and

 

the associated binary values are shown in Sec tion 9.
