If the current loop is set for 0 to 20 mA operation, the A–LO function will not appear as a
menu item. The analog output always goes to 0 mA if the measured temperature is below
the Analog Output Zero Sale temperature.
5.7.3 A–HI – Analog Output High Temperature Alarm
Sets the Analog Output current value if the measured temperature is above the temperature that
produces Analog Full Scale Output as determined by the Analog Output Full Scale Temperature Scaling
explained above. Selectable range is 20.0 mA to 24.0 mA.

5.8 COMM – Setup of RS-485 Digital Communication Configuration
The Modline 5 RS-485 Digital Communication interface permits interchange of ASCII coded
information between the Modline 5 Sensor and a host computer, PLC (Programmable Logic Controller),
or any other RS-485 device.
The RS-485 data signal is transmitted on the Yellow and Yellow/White twisted wire pair of the Sensor’s
interconnecting cable. All communication is via half-duplex two wires.
Refer to section 6 RS-485 Digital Communications , page 107, for the complete explanation of the RS-485
