INFORMATION!
The signal converter has a dual process input, A and B. Each process input has an own submenu
in this main menu. Process input A is always present, i.e. there is always a board in the interface
"Pos.A" in the connection area. The interface of process input B only has a board with the dual
channel signal converter. Be aware that the definition which kind of measurement a process
input can do is defined when ordering the device. The configuration cannot be changed later.
INFORMATION!
Note that the appearance of some submenus depends on the hardware setting and the used
sensor(s).
Level Designation / function Settings / descriptions
Process input A and B can be either a sensor 1 or a sensor 2. Further information about the type of sensor 1 or 2 please
refer to MAC 100 manual "Sensor input combinations". Process input A is always present, process Input B can be
present.
Note: The exchange of a sensors 1 with a sensor 2, or vice versa, can only be done by the manufacturer!
Depending on the sensor which is connected to a slot A or B the menu changes.

This menu item is for selecting the probe which is connected to process
input A/B. The entries of this selection depends on the chosen device
configuration. The device configuration is customer specific and set during
production.

probe Options:
• manual: used if no internal or external temperature sensor is connected to
the signal converter
• Pt100: used if the pH electrode has an integrated Pt temperature
measurement or if an external Pt100 temperature sensor is connected to
the signal converter
• Pt1000: used if an external Pt1000 temperature sensor is connected to the
signal converter
• process input A: choose this option if there is a temperature sensor
connected to input A of the signal converter
