PROGRAM PARAMETERS Parameter OPERATION MANUAL Description Fac tory De fault APSCAL Absolute Pressure Span Calibration. The Absolute Pressure Span Calibration value is the 20 milliamp (span) count value from the external 4-20 milliamp ‘absolute pressure’ input channel. This parameter is used to calibrate the span point of the incoming 4-20 signal from the external absolute pressure device. To calibrate the span point of the incoming 4-20 signal, press the EDIT key. The screen will display IN20MA.
OPERATION MANUAL Parameter OUTPTG PROGRAM PARAMETERS Description Fac tory De fault 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.
PROGRAM PARAMETERS Parameter OPERATION MANUAL Description Fac tory De fault P_WORD Password. The password is used to prevent unauthorized access to the 0 = Password programming parameters. The password may be any value between 0 Disabled and 9999. A password value of 0 disables the password feature. BD_ENB Blow Down Enable. The Blow Down Enable parameter allows the user to enable or disable the integrated blow down sys tem. 0 = Blowdown Disabled. • A value of ‘0’ disables the Blowdown Sequence.
OPERATION MANUAL ALARM PROGRAMMING INFORMATION 9. ALARM PROGRAMMING INFORMATION 9.1 Alarm ‘ENABLE’ Word Definition The ALARM ‘ENABLE’ WORD (16 bit word) is divided into two 8 bit bytes. The lower order byte (bits 1 – 8) is used to enable and disable the alarm functions. The higher order byte (bits 9 – 16) is used t o control how the alarm is displayed and/or output to the user interface. Some bits are currently undefined and reserved for future use.
ALARM PROGRAMMING INFORMATION OPERATION MANUAL E. Latched Output: Enabling the Latched Output bit will cause any active alarm to become latched and held active even if the alarm condition clears. Any ‘latched’ alarms can be cleared during RUN mode by pressing the EDIT key (if the active alarm(s) are no longer active). After pressing the EDIT key, any latched alarms that are no longer active will be cleared and any alarms that are still active will remain latched. F.
