Problems with Temp Sensor or
Pressure Transducer Displaying
Proper Value
16AI input dip switches are
set incorrectly.
The 16 dip switches on the 16AI board correspond

Dip Switches Up = Temperature Sensor
Dip Switches Down = Pressure Transducer

address.
Set proper board and point settings for both input

Setup screen and check Board and Point.

temperature sensor.
NOTE: The previous Eclipse and Standard sensors
are now 5V and 12V respectively.
