Input mA Contact Honeywell Analytics' Service Department�
Indicates that mA input from sensor is less than 3 mA� Check wiring
between XNX and sensor� Also check the switches S3 and S4 are set
Input mA correctly� If the switch settings need to be change, power down the XNX
before changing the switch settings� If wiring and switches are okay,
replace sensor�
constant current A/D Check that correct mV sensor type is selected� Check wiring between
input mV XNX and sensor� If sensor type and wiring are okay, replace sensor�
Current baseline Perform zero calibration� If problem persists, replace sensor�
