Installation Overview

The BluKey (BK) Pulse device can be installed as a cashless, mobile payment option in coin-operated laundry appliances that use a pulse payment system. BK Pulse credits a machine by sending pulses, working the same way as if cash has been inserted. Using the RelayModule Harness Kit, the BluKey device can be connected to the coin acceptor to allow coin pulses to pass through unimpeded, while upgrading your machine to also accept mobile payments. The machine must have a coin acceptor to be compatible with the PayRange RelayModule.

Note: Coin acceptor must be pulse-type, RelayModule cannot interface with serial or MDB hardware.

Note: Ignore the twisted yellow/white pair of wires located on the RelayModule Harness for BluKey Pro (these wires will not be used at this time).

Installation Steps

Note: PayRange service requires data connection on a user’s mobile device. Prior to installation, verify location has adequate cellular reception or a WiFi network that users can access. If mobile web browser can load a website relatively quickly, data connection should be adequate.

Step 1: Prepare Machine

• Completely disconnect power (unplug or turn off breaker)
• Open machine control panel or lid to access coin acceptor and locate a power source

Step 2: Locate Power Source and Connect Adapter

The RelayModule is equipped with a DC jack which connects to a High Voltage or Low Voltage power adapter (included with harness). Do not attempt to modify the power connector or connect a power adapter that was not provided by PayRange.

Input Range

• Low Voltage: 20-36 VAC/VDC
• High Voltage: 100-240 VAC

1. Use the machine wiring diagram and a voltmeter to locate a wire pair carrying constant power within the appropriate voltage range
   Note: A label on a power transformer can be very helpful to identify voltages present. A section showing common power connections coming soon, bookmark this link and check back for updates.
2. Connect one input wire from the power adapter to one of the machine power supply wires
3. Connect remaining power adapter input wire to remaining power supply wire
4. Connect power adapter to Relay Module DC jack

Step 3: Connect BluKey to Relay Module. (Configure Laundry Interface Module if applicable)

Switches must be set to match install scenario. Incorrect settings may cause BluKey (BK) to behave unexpectedly.

Switch 1:

• Ensure it is set to ON position.

Switch 2:

• Ensure it is set to ON for ALL machines.

Switch 3: Set ON for all machines.
Switch 4: Unused

Step 4: Identify Coin Acceptor Type and Connection Method

The Relay Module harness has three wire leads for credit output. Only two will be used for any installation depending on coin acceptor type (COM & NO or COM & NC):

This guide splits coin acceptors into four categories: Optical Sensor, Microswitch, Coin Slide, and Third-Party. Determine machine coin acceptor type based on the category descriptions, then proceed to the respective section for connection method.

Optical Sensor: One coin inserted at a time, coin drops from chute through optical sensor opening, typically have three or four wire leads (some older optical sensors used five wire leads). See the Common Optical Sensors section below.

Microswitch: One coin inserted at a time, coin drops through chute and hits a wire lever/actuator, typically only two wire leads (there are three connection terminals, but only two are used). See the Microswitch Coin Acceptors section below.

Coin Slide: Multiple coins inserted at once, coins placed vertically in slide mechanism which can then be fully pushed in. Not all coin slides are compatible, see section for more information. See the Coin Slides section below.

Third-Party: This category includes retro-fit, aftermarket and multiple-denomination coin mechanisms. Such as Imonex, Setomatic, Keltner Research, etc. See the Third-Party Coin Acceptors section below.

Step 5: Verify installation

• Leave control panel open and restore machine power
• Verify solid blue LED on BluKey
  If status LED is off, flashing, or incorrect color, see Troubleshooting / Light Codes below

Step 6: Verify Machine Operation

Follow recommended procedure in Testing After Installation below to test mobile and coin payment

Microswitch Coin Acceptors

Common in Dexter equipment, also used by other manufacturers. A microswitch typically has three terminal contacts but only two are used. Each terminal identifier should be printed or etched on one side of the switch.

Figure 1 shows the most common pinout, but some switches have NC and NO reversed. Dexter uses the pinout shown; if the machine is not Dexter, check markings on switch to verify terminal orientation prior to install.

• NO: Normally Open
• NC: Normally Closed
• COM: Common (always used)

Normally Open (NO) Connection

Almost all microswitch acceptors are wired NO and use this connection method.

DEXTER machines are usually wired in NO orientation. Sometimes they’re NC but work either way. If switch is wired NC, remove the wire from NC terminal and connect to NO, then insert a coin or press the switch manually to verify the machine still receives credit. If it does, use the NO connection method; if it does not, move the wire back to the NC terminal and use the NC connection method.

1. Connect yellow wire (pin 1) to a wire connected to either COM or NO terminal (connection is not polarity sensitive)
2. Connect blue wire (pin 2) to a wire at opposite terminal (NO or COM)
3. Tie unused white wire (pin 3) to prevent contact with any part of the machine

Normally Closed (NC) Connection

Not common.

2. Connect yellow wire (pin 1) to one end of cut wire (connection is not polarity sensitive)
3. Connect white wire (pin 3) to remaining end of cut wire
4. Tie unused blue wire (pin 2) to prevent contact with any part of the machine

Coin Slides

Compatible coin slides activate an electronic timer. Mechanical timer coin slides are not compatible with the RelayModule harness. Timer type can be verified by looking under the service door.

Electronic timers usually have a switch behind the slide, but some use an optical sensor. Fish wiring through conduit so PayRange hardware can be placed behind the control panel and not under the service door where it may obstruct coin slide movement.

Coin Slide Switch Connection

Wires will be connected to two terminals on the switch.

1. Connect yellow wire (pin 1) to a wire connected to either switch terminal (connection is not polarity sensitive)
2. Connect blue wire (pin 2) to a wire connected to remaining switch terminal
3. Tie unused white wire (pin 3) to prevent contact with any part of the machine

Coin Slide Optical Sensor Connection

Affixing Machine Decals

• Number Decal – a unique number decal must be affixed to every laundry machine equipped with PayRange. Number decal not used for vending applications.
  • The decal should be placed on the machine in an area that is easily visible (near the coin slot is recommended) and that makes it obvious which machine the number is for.
  • Number machines left-to-right and top-to-bottom to make it easier for customers to locate machines. For stacked machines that require two devices, top machine should be lower number.

Note: Dexter and Maytag stacked machines only require a single device, and therefore should have a single number decal

• First Purchase Free Decal – this decal should be used only if the ‘New User Program’ is enabled on the operator account.
  • The New User Program allows brand new PayRange users to make a single transaction without adding funds and is a great way to incentivize mobile pay adoption.
  • To enable/disable feature, and set the maximum amount for transaction: login to Manage Console → select “Rewards” → select “New User Program”

Price Examples

It’s recommended to add a 25¢ option for all machines for greater flexibility (Quarter, Upgrade Cycle, Extra Dry Time, Top-Off)

Washer with Tiered Pricing

Full Cycle Dryer

Testing After Installation

It is critical to test each BluKey device to verify proper installation and setup. Use the app without adding funds by creating a Free Purchase offer (see the Laundry Operator Introduction Guide for instructions). Testing coin acceptor is also recommended, if applicable.

Recommended test procedure:

Repeat steps for all machines.

1. Select a machine from the app list. Select a 25¢ option from the price dropdown (“Quarter”, “Extra Dry Time”, “Top-Off”, “Upgrade Cycle” etc.) then swipe to pay,
2. Machine display should decrement by only 25¢ (or 1 coin).
   If display decrements by more, or not at all:
   1. Verify 25¢ price row is set for 1 pulse in device pricing
   2. Verify correct pulse timing
   3. Verify machine is programmed as described in installation steps
3. If machine accepts coin, insert coin, and verify machine receives credit. If not successful, check connection at coin pass-through harness.
4. Select full cycle price in app and swipe to pay again (for metered dryers, select option for at least $1.00). Machine display should quickly decrement reflecting the amount paid (or add time to metered dryer) and allow cycle to start.

Note: if app shows “Machine in use” and does not allow additional payment, verify correct switch settings on Laundry Interface Module.

Troubleshooting / Light Codes

Using 3M™ Scotchlok™ IDC Tap Connectors

Tap splice connectors make it possible to splice anywhere along a wire without having to first cut the wire. A tap splice connector has a metal brace with two slots in it; one for each wire that goes into the connector. When the brace is crimped down it is designed to cut through the insulation only. This allows the metal brace to contact the strands of conductive wire, which connects the two wires in the connector.

Using Included Red Tap Splice Connectors

1. Make sure brace is pulled out of splice far enough so wires can be fully inserted 

2. 

3. Insert the machine wire into the pass-through side of the connector 

4. 

5. Close the first part of the tab 

6. 

7. Insert a wire from BK Smart harness into the other slot of the splice connector. Push wire all the way in until it hits the stop 

8. 

9. Crimp the metal brace all the way down until it is flush with the plastic part of the connector (crimp from the center to ensure brace crimps down straight and even) 

10. 

11. Close the cover fully and check that the wire cannot be pulled out with a slight tug
