Low Gas Warning Limit

As the 

OPTI

mizer

2

 monitors the SF

6

 density or pressure, 

an alarm will be asserted when the density or pressure 

reaches or falls below the programmed Low Gas Warning 

Limit. 
The Low Gas Warning Limit can be set to the circuit 

breaker manufacturer’s “Alarm Limit” specification. If 

the 

OPTI

mizer

2

 is used in conjunction with an electro-

mechanical SF

6

  monitoring device, this Warning Limit 

can be set higher than the manufacturer’s “Alarm Limit” 

specification to provide an “early warning” that SF

6

 density 

or pressure is getting low.

Note:  

When the 

OPTI

mizer

2

 is cold-started, the Low 

Gas Warning Limit parameter is set to ZERO, which 

disables this alarm.

To set the Low Gas Warning Limit, select the 

CONFIGURATION tab and click “EDIT”:

Program:

 

Low Pressure Warning Limit = “76”

 

or

 

Low Density Warning Limit = "39.8"

Low Gas Alarm Limit

An alarm will be asserted when the density or pressure 

reaches or falls below the programmed Low Gas Alarm 

Limit. 
The Low Gas Alarm Limit can be set to the circuit 

breaker manufacturer’s “Lock-Out Limit” specification. If 

the 

OPTI

mizer

2

 is used in conjunction with an electro-

mechanical gas monitoring device, this Alarm Limit can 

be set higher than the manufacturer’s “Lock-Out Limit” 

specification to provide an “early warning” that a Lock-Out 

is imminent.

Note:  

When the 

OPTI

mizer

2

 is cold-started, the Low 

Gas Alarm Limit parameter is set to ZERO, which 

disables this alarm.

To set the Low Gas Alarm Limit, select the 

CONFIGURATION tab and click “EDIT”:

Program:

 

Low Pressure Alarm Limit = “72”

 

or

 

Low Density Alarm Limit = "38.2"

Density or Pressure Trend Limit

The

 OPTI

mizer

2

 will analyze the SF

6

 density and pressure 

fluctuations over a 15 day period and calculate the Density 

and Pressure Trends once an hour. The magnitude of these 

trends indicate whether the SF

6

 density and pressure are 

stable or decreasing. The Density Trend is expressed in 

grams-per-liter-per-day  (g / L / d). The  Pressure Trend  is 

expressed in the chosen units-per-day. They are shown as 

negative numbers in the Status, if there is a loss of gas. The 

Trend Limit is programmed as a positive number. 
An alarm will be asserted when the magnitude of the trend 

is the same or greater than the programmed Trend Limit.

Note:  

When the 

OPTI

mizer

2

 is cold-started, the Trend 

Alarm Limit parameter is set to ZERO, which 

disables this alarm.

To set the Trend Alarm Limit, select the CONFIGURATION 

tab and click “EDIT”:

Program:

 

Density Trend Alarm Limit = “0.03”

or

 

Pressure Trend Alarm Limit = "0.3"
