Chemical Connections for Milnor Washers

We send a signal to the chemical system. This signal may be vary in voltage based on the machine. Typically, washer-extractors will use 240VAC or 120VAC signals while a CBW tunnel washer would have the option for "potential free" contacts.

Be sure to confirm if the chemical signal is 240VAC or 120VAC first.

The table below shows connection points for various washer-extractors. Note that these terminals are often found close to the primary incoming power terminal blocks.

For screw terminal connections, C1 - C8 are controlled relay outputs of 240VAC or 120VAC. SC is the supply common. To create a "potential free" contact, a 240V or 120V relay will need to be supplied for each chemical necessary. For example wire C1 and SC to coil of the additional relay.

For terminal block connections, 95, 93, 91, 75, 85 are controlled relay outputs of 240VAC or 120VAC. 6 is the supply common.
