Network Model Operation

The Network Model varies from the Standalone Model for Start-Up only in
that the LEDs have different functions.
LED Description
I/O Power
1 Built-in sensor Alarm A
2 Transmit
Sensor Warm Up
When the monitor is first powered up, sensors must go through a 5 minute
warm-up (15 minutes for the O
displays Warm-Up. The 4-20 mA is maintained at 4 mA for all sensors;
however, the O sensor is maintained at (approximately) 17.4 mA (equal to

20.9%).
Allow the sensor to operate for 12 hours with the enclosure closed prior to
testing the sensors. Optimal sensor performance is achieved 3 to 4 hours
after initial power up.
