: Pass the system cables through the appropriate M20 or M25 entry ports using approved explosion-proof conduit seals or cable glands. Connect Power and Signal : Wire the Terminal 1 to 24V DC positive (+). Wire the Terminal 2 to 0V DC negative (-).
Input the exact concentration value of the calibration gas cylinder you intend to use.
: Re-attach the housing cover, turning it clockwise until tightly sealed. Tighten the security catch screw. User Interface and Basic Operation
However, versatility comes with complexity. A rushed installation can lead to false alarms, communication errors, or hazardous conditions. This will walk you through the first 60 minutes of your Xnx transmitter’s life: mechanical mounting, electrical termination, sensor initialization, and basic menu navigation.
