Example 2:
An MFC-Cl
2
++ (master or slave) is installed with an MFC pH in
order to compensate the chlorine measurement with the pH value.
In this application, both units need not be operated in the same
segment. In the following example, segment 1 is used and the
following settings must be carried out.
Example 3:
An SFC-Cl
2
is installed with an MFC setpoint trim. The Cl
2
measurement is transmitted from the SFC to the MFC via CAN.
The following table lists possible settings for the MFC and SFC.
The measurements are transmitted in segment 1 to address 2.
A bus end (bus termination Rt) must be installed at the first and last
units in the bus. The MFC is equipped with a RT dip switch. Other
units (dip switch number 4 on switch block between terminals 22
and 23) require a menu setting that activates the bus termination.
Balancing of the CAN bus must take place once in the CAN bus.
However, the MFC does not offer this option.
