External Supplies
For proper communication between the machine and an external
chemical supply system, it is important for the low-voltage signal
power to be connected properly. The included wiring diagram
shows several different options for safe and correct wiring of this
interface.
The preferred method for connecting the wiring from the external
chemical supply system to the machine is to use the 300mA pow-
er of the machine’s 24VAC control transformer, which is inten-
ded strictly for this purpose. Other voltage and current options
are available, but require some wiring changes and must be pro-
vided with an external power source. Under no circumstances
should the high-voltage machine supply connections or source be
used for the communication wiring.
Communication wiring connections, which include a single row
of identified terminal blocks, can be found under a service panel
at the upper back of the machine.
