22. ALARM LATCH FUNCTION
Write Command: 2b
Read Command: 5f
Interpret: 0 == NO LATCHES
1 == ALARM1 LATCH
2 == ALARM 2 LATCH
3 == ALARM 1&2 LATCH
23. ALARM1 DEADBAND
Write Command: 2d
Read Command: 61
Interpret: The span in temperature that the control sensor (INPUT1) must move before the ALARM1 output is
toggled off. For writing, multiply the desired deadband by 100
10
, and then convert to hexadecimal. For
reading, convert the hexadecimal value to decimal, and then divide by 100
10
.
1.00

24. ALARM2 DEADBAND
Write Command: 2e
Read Command: 62
Interpret: The span in temperature that the secondary sensor (INPUT2) must move before the ALARM2 output is
toggled off. For writing, multiply the desired deadband by 100
10
, and then convert to hexadecimal. For
reading, convert the hexadecimal value to decimal, and then divide by 100
10
.

25. SENSOR FOR ALARM2
Write Command: 3a
Read Command: 6e
Interpret: 0 == monitors INPUT2 for ALARM2
1 == monitors INPUT1 for ALARM2
26. ANALOG OUTPUT MULTIPLIER
Write Command: 2f
Read Command: 63
Interpret: For writing, multiply the desired analog output multiplier by 100
10
, and then convert to hexadecimal.
For reading, convert the hexadecimal value to decimal, and then divide by 100
10
. The allowable range
is 0 to 1.00.
0.00 multiplier would be 0
0.50 multiplier would be 50
10
1.00 multiplier would be 100

27. LATCH CLEAR
Write Command: 75
Read Command: NA
Interpret: Send this command to reset alarm latches.
28. OUTPUT ENABLE
Write Command: 30
Read Command: 64
Interpret: 0 == OFF
1 == ON
