Glossary

Adv Hi Level

Advisory High Level alarm set point. When the product level exceeds this point an advisory alarm will be generated.

Adv Hi Temp

Advisory High Temperature alarm set point. When the product temperature exceeds this point an advisory alarm will be generated.

Adv Lo Level

Advisory Low Level alarm set point. When the product level drops below this point an advisory alarm will be generated.

Adv Lo Temp

Advisory Low Temperature alarm set point. When the product temperature drops below this point an advisory alarm will be generated.

Adv Rtd Level

Advisory Resistive Temperature Device Level. Height of the RTD in the tank. An alarm is generated when the level goes below this level (temperature measurements can no longer be made).

Advisory Alarms

Process alarms intended to act as caution indicators providing users advanced warnings of unusual situations.

ATT

Varec Model 4000 Advanced Technology Transmitter.

ATTI Bus

Unpowered, non-intrinsically safe, HART compatible communication bus used on ATT.

Baud Rate

A communications measure of serial data transmission rate typically in bits per second. Normal baud rates for RS-232 interfaces are 300, 1200, 2400, 4800, 9600, 19200. The higher the baud rate, the faster the data transfer occurs across the data line.

Comm Port

Communication Port. An access point for data entry or exit.

Crit Hi Level

Critical High Level alarm set point. When the product level exceeds this point a critical alarm is generated.

Crit Hi Temp

Critical High Temperature alarm set point. When the product temperature exceeds this point a critical alarm is generated.

Crit Lo Level

Critical Low Level alarm set point. When the product level drops below this point a critical alarm is generated.

Crit Lo Temp

Critical Low Temperature alarm set point. When the product temperature drops below this point a critical alarm is generated.

oC

Celsius. A unit of measure for temperature readings. 0 oC is the freezing point for water, 100 oC is the boiling point of water.
