This procedure is also shown pictorially on the previous page.
1. Enter the “Limit 3 Rule.” This means you must select the function to trigger the Limit 3 relay.
Options are:

Job Total for A

Job Total for B

Job Total for A+B

Flow A

Flow B

Flow A+B
Press F4 to page through the options; press F6 to enter your selection.
The display flashes “DP Location Will Match KFT/KFR.” This means the number you entered for the Limit
trip point automatically takes the same decimal point location as the Total Scaling Factor (KFT) for Total
Limits, or Rate Scaling Factor (KFR) for Flow Rate Limits.
2. Type in the Limit 3 value; press F6 to enter (you must enter the Limit 3 number to proceed to
Limit 4).
3. Enter the Limit 4 Rule and number exactly as above (you must enter the Limit 4 number to
proceed to Limit 2).
4. Enter the Limit 2 Rule.
If you select Ratio A/B, the Limits 1 and 2 operate on the ratio percentage of error under F3 Ratio
Programming. Therefore, if you select Ratio A/B, limit programming is complete.
In another scenario, you can program Limit 1 and 2 for Warning and Alarm settings on Flow A, while you
can allocate Limit 3 and 4 to Warning and Alarm for Flow B or Flow A+B and Total B, respectively. In this
case, you can select Limits 3 and 4 independently but you cannot separate 1 and 2.
Other options are as follows (page using F4; enter, F6):

Ratio A/B

Job Total for A

Job Total for B

Job Total for A+B

Flow A
