Examples:
Channel Input Type Setpoint Entered Interpretation
Thermocouple 0050 50 Degrees F
Millivolt Range 0050 5.0% Full Scale
NOTE: No internal check is made to confirm that the setpoint entered is valid within
the channel input TYPE operating range. It is the users responsibility to insure that
valid setpoints are entered with respect to the channel type designated.
To set the High Alarm setpoint:
X (n) H (abcd) <CR> n is the loop number 1 to 8
H is the high alarm indicator
abcd is the setpoint, 0 to full scale
Example:
Command: X1H1100 <CR> sets loop 1 (J T/C) high alarm at 1100F
Response: X1H1100 <CR><LF>
X (n) HQ <CR>
Example:
Command: X1HQ <CR>
Response: X1H1100 <CR><LF>
To set the Low Alarm setpoint for a given loop:
X (n) L (abcd) <CR> n is the loop number 1 to 8
L is the low alarm indicator
abcd is the setpoint, 0 to full scale
Example:
Command: X2L0100 <CR> Sets loop 2 (Millivolt input) lower alarm
value at 10 % Full Scale
Response: X2L0100 <CR><LF>
To query the low alarm value for a given loop:
X (n) LQ <CR>
