External Supplies
For proper communication between the washer-
extractor and an external chemical supply system, it is
important for the signal power to be connected
properly. The included wiring diagram (F8133502)
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 washer-
extractor is to use the 300mA power of the washer-
extractor’s 24VAC control transformer, which is
intended strictly for this purpose. Other voltage and
current options are available, but require some wiring
changes and must be provided 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.
