Johnson Controls XT-9100, XP-910x appendix AI Input Type Alarm Limits

AI Input Type: Alarm Limits

Via the SX Tool

Input Type:
X7 = 0	0-10 volts
X7 = 1	0-20 mA
X8 = 1	20% suppression 2-10V or 4-20 mA)

Linearization and Sensor Type:

X11 X10 X9 = 000	Linear (Active Sensor)
X11 X10 X9 = 001	Ni 1000 RTD Passive Sensor (JCI Type)
	(-45 to +121°C/-50 to +250°F)
X11 X10 X9 = 010	Ni 1000 RTD High Temperature Sensor
	(+21 to +288°C/70 to +550°F)
X11 X10 X9 = 011	RTD Sensor A99
	(-50 to +100°C/-58 to +212°F)
X11 X10 X9 = 100	RTD Sensor Platinum 1000
	(+50 to +200°C/-58 to +320°F)

For active inputs, each analog input module channel performs the conversion of the input signal to a numeric value using the high range at Item HRn (RI.89, RI.97, RI.105, RI.113, RI.121, RI.129, RI.137, and RI.145) and low range at Item LRn (RI.90, RI.98, RI.106, RI.114, RI.122, RI.130, RI.138, and RI.146).

For RTD inputs, the range of the displayed value is fixed according to the type of sensor.

The high limit and the low limit define at which levels the analog input reading will generate an alarm, either for remote monitoring or for internal use within the control sequences in the DX-9100.

Note: The limits cannot be deleted. If you do not want alarms, enter limits beyond the range.
