Table 10.18. Setpoint 1 Configuration (“SP CNF”), Bits 2, 1, and 0

BIT NUMBER

2 1 0

CONFIGURATION

x x 0 SP 1 active above

x x 1 SP 1 active below

x 0 x Out transistor #1 on if SP 1 active

x 1 x Out transistor #1 off if SP 1 active

0 x x SP 1 uses unfiltered value

1 x x SP 1 driven from filtered value

Table 10.19. Setpoint 2 Configuration (“SP CNF”), Bits 5, 4, and 3

BIT NUMBER

5 4 3

CONFIGURATION

x x 0 SP 2 active above

x x 1 SP 2 active below

x 0 x Out transistor #2 on if SP 1 active

x 1 x Out transistor #2 off if SP 1 active

0 x x SP 2 uses unfiltered value

1 x x SP 2 driven from filtered value

Table 10.20. Setpoint Configuration (“SP CNF”), Bits 7, and 6

BIT NUMBER

7 6

CONFIGURATION

x 0 Enable SP 1 and SP 2

x 1 Disable SP 1 and SP 2

0 x Enable LEDs 1 and 2

1 x Disable LEDs 1 and 2

EXAMPLE: The computer requests the SP 1 and 2 status from the RAM of meter #15 hex with:

“*15G10<CR>”, and the meter responds without echo: “2F<CR>”, indicating that:

Setpoint 1 and its LED are enabled, active below, driven by the filtered measurements, with its transistor active

when that SP is OFF, and

Setpoint 2 and its LED are enabled, active below, driven by the filtered measurements, with its transistor active

when that SP is ON.

10.10 Alarm (Setpoints 3 And 4) Configuration (“AL CNF”)

The encoding of the byte for this “11” command suffix is identical with that immediately above for SP 1 and 2

except that the most significant bit does not allow the LED to be turned off when an alarm is ON (set this bit to

“0”, i.e., keep the MSN under 8).

Table 10.21. Alarm 1 (SP 3) Configuration (“AL CNF”), Bits 2, 1 and 0

BIT NUMBER

2 1 0

CONFIGURATION

x x 0 AL 1 (SP 3) active above

x x 1 AL 1 (SP 3) active below

x 0 x Out transistor #3 on if AL 1 (SP 3) active

x 1 x Out transistor #3 off if AL 1 (SP 3) active

0 x x AL 1 uses unfiltered value

1 x x AL 1 driven from filtered value
