This installation note covers L-series washers, such as L1125. Pulse control is used. Work in progress
Required parts
Reader
Cable harness
12Vdc power supply
High-Voltage sensor box (for sensing machine state/availability)
Installation Steps
Step 1: Turn Machine Power Off
Step 2: Remove coin-drop if present
Step 3: Number the reader using the DIP switch
See Reader DIP Switch settings
Step 4: START wires connectionOpen the machine and locate the brown wires with female spade connectors as shown below. There should be BLUE wires coming from X9-7 and X9-11 on the machine; these wires may be loose or going to an existing coin drop. Disconnect from the coin-drop if needed. Connect these two blue wires to the White and Green wires (called the START wires) on the provided cable harness (not shown)
On L1125, L1075
Machine Schematic - Coin Switch InputsOn L1040, the wires might be 37 and 38
Step 5: High voltage sensor connection
Locate the two blue wires with female spade connectors with as shown in the step above. These wires tie back to a 230Vac In-Use signal and will enable the reader to know when the machine is and is not available for payment. Connect these wires to the two red wires from the provided High Voltage sensor box.
Step 6: Reader Power ConnectionConnect the 120Vac side of the power supply, either to an available wall outlet, or splice the power supply directly to the machine, using an appropriate high-voltage connection inside the machine.When connecting to the machine directly, you'll be cutting off the AC prong, and splicing these wires directly to the machine (we recommend consulting the manufacturer, or an electrician, to confirm this type of connection).
Step 7: Mount the reader to into the place where the coin-drop would normally mount.

Note that the reader, is emulating a coin drop, and ONLY sends one pulse to trigger the machine to start.
You'll need to configure the machine to start a cycle off of this ONE pulse.
