Operation with two external temperature probes is supported by the
Integral IN and Variocool NRTL product lines.
The following is valid for Pt100/LiBus modules with coding switch:
The printed circuit board on the Pt100/LiBus module has a coding switch for
setting the address of the Pt100 interface:
Position 0: The Pt100 interface is assigned the name
External Pt100
(factory setting) in the menu of the constant temperature equipment.
Position 1: The Pt100 interface is assigned the name

.
Positions 2 – 9:
Currently without any function.
Only change the setting if you want to use this Pt100/LiBus module
to operate a second external temperature probe on the constant
temperature equipment.
Check the coding switch setting before installing the Pt100/LiBus
module in constant temperature equipment.
Setting the address of the second Pt100 interface:
1.
Use a slotted screwdriver to set the adjusting wheel (1) on the coding
switch.
2.
Turn the adjusting wheel (1) to position 1 (2) to address the Pt100
interface with the name
