Assignment of binary inputs
The Smartec S CLD132 transmitter has 2 binary inputs. They can be defined in field M1 as follows:
Settings of the 4 parameter sets
Example: CIP cleaning
Assignment of field M1 Assignment of binary inputs
M1 = 0 MRS not active. The binary input 1 can be used for external hold.
M1 = 1
The binary input 2 can be used to switch between 2 measuring ranges (parameter
sets). The binary input 1 can be used for external hold.
M1 = 2
The binary inputs 1 and 2 can be used to switch between 4 measuring ranges
(parameter sets). This is the setting used in the following example.
Binary input 1 0 0 1 1
Binary input 2 0 1 0 1
Parameter set 1 2 3 4
