The Big Idea
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 signals while a CBW tunnel washer would have the option for "potential free" contacts.
240V Connections
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.
C1 - C8 are controlled relay outputs of 240VAC.
SC is the supply common. To create a "potential free" contact, a 240V relay will need to be supplied for each chemical necessary. For example wire
C1 and
SC to coil of the additional relay.
