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. Refer to Figure 30.
