Emerald Controls
This article covers installation of readers on Wascomat washers with Emerald controls (like E620 SU655E). The readers use pulse control
Required parts
- Reader (model CR-11-118-04. The board inside the reader must be "Generic Relay")
- Cable harness
- 12V power supply
- Splicers
- Installation Steps
Step 1: Turn Machine Power Off
Step 2: Remove coin-box
Step 3: Number the reader using the DIP switch
Step 4: Signal Connector
The reader simply replaces the coin-drop connection.
On most Emerald control washers you should see a coin board shown below with the X221 (Coin 1) connection slot. Connect the 3-pin signal connector (with white and green wires) to this slot.
There are some models that do not have this board. Instead these models have screw terminals shown below. In this case, connect the green/white wires from the cable harness to pin 1 and pin 3 (polarity does not matter).

Step 7: Activate Reader
Use the provided Activation card to activate the reader:
Setting Vend Prices
