Formula Selector Wiring: (Metric Models)
With the Metric Multi-Washer 3000 units, the Formula Selector(s) are connected directly to the control board, at the second
level of the X2 terminal block, as shown below. Brown to "-", Yellow to "+", White to A3 and Green to B3. If multiple
Formula Selectors are being connected, they must be connected in parallel, either at the control board or (recommended)
using a standard terminal box, as shown.

Washer Signal Wiring: (North America Models)
Be sure the unit is turned off, powered down, before connecting the communication boxes!
The North America Multi-Washer 3000 models use Communication Boxes as the interface between the signals coming from
the washer and the formula programming to deliver certain products at certain times. The simple On/Off signals from the
washer are translated into digital packets of information and transmitted back to the Multi-Washer control board over a digital
network. This allows a single four-wire cable to daisy-chain from one communication box to another, simplifying installation.
The connection at the main panel is on the second bank of Terminal Block X2; Black to "-", Red to "+", White to A1 and
Green to B1 as shown below. The four conductor cable runs to the "In" connector of the box closest to the main panel. Any
remaining boxes are connected with a cable running from the "Out" connector to the "In" connector of the next box.
The boxes are identified to the PLC by the DIP switch settings as shown below. If you are using the Remote Formula
Selection accessory, their DIP switches must be set to match the Communication Box to which they are connected.
