The 250 ohm resistor for milliamp inputs or the voltage divider for 0-10 Volt inputs are supplied 
with the controller when those inputs are specified. These items must be installed prior to start 
up when the controller is wired. For 0-20 mA applications, the resistor should be located at the 
transmitter terminals if Burnout detection is desired.
1
Splice and tape this junction between the two thermocouples. This junction may be located 
anywhere between the thermocouples and the instrument terminals, it does not need to be close 
to the other thermocouple junctions. Both thermocouples must be of the same type. For best 
accuracy, the two thermocouples should be matched or, preferably, made from the same batch 
of wire.
2
This controller does not produce a steady current for burnout detection. For that reason, when a 
thermocouple is used in parallel with another instrument, it may be desirable to configure the 
burnout selection for this controller to “NOFS” and use the burnout current from the other 
instrument to also drive this controller.
