Multiple controllers
Several controllers can be connected to a single capacitance probe or a 4 - 20 mA (self-powered
or loop powered) source.
Connect wiring as shown in the Figures 8, 9 and 10.
Note: As an example, terminal numbers and switch positions of a second LC2300 are shown.
Wiring connections for other Spirax Sarco controllers / transmitters are different, and are given
in the individual Installation and Maintenance Instructions.
