The Authority22 and Envoy lane machines have used different types of "End of Lane sensors" since their inception. The current part number for the sensor is 14-100235-091. This sensor (3rd Gen) can be used in both the Authority22 and Envoy lane machines.

Authority22 End of Lane (EOL) sensor types:

   1^st Generation was an adjustable type that was 3-1/8” long (85.3mm).

   2^nd Generation was a photo-optical type that was 2-1/8” long (55mm) and is NOT adjustable.

   3^rd Generation (Current) is an adjustable type that is 1-1/4” long (33mm).

Envoy End of Lane (EOL) sensor types (Same as A22):

   1^st Generation was a photo-optical type that was 2-1/8” long (55mm) and was NOT adjustable.

   2^nd Generation was an adjustable type that was 1-1/4” long (33mm).

Authority22 1st Generation End of Lane Sensor Replacement and Adjustment

The Authority22 first generation End of Lane sensor is a Capacitive Proximity Switch. The base is 3-5/16” long (85.3mm) and is adjustable.

Tools needed:

• (2) 15/16” wrenches or adjustable wrench.
  

Replacing the 1^st generation (A22 Only) End of Lane Sensor

1. Place machine in transport position with the cover open and power supply disconnected.
2. Loosen and remove nut at base of sensor.
3. Remove black O-ring from base of sensor.
4. Disconnect sensor cable from the quick-connect cable harness.
5. Pull sensor out from the top side of the machine and remove the second O-ring on top side of the sensor.
6. Place an O-ring under the top-side nut and then install new sensor from top side of the machine so that sensor extends 1-3/8" or 35mm beyond shield.

Note: The sensor must be set in proper position for accurate operation.

7. Place the second O-ring on the sensor pushing it up to the bottom side of the mounting shield.

8. Insert and tighten nuts at base of sensor.

9. Adjust sensor as needed.

Adjusting the 1^st generation (A22 Only) End of Lane Sensor

Tools Needed:

• Small screwdriver included in the spare parts

  kit.

• An accurate measuring device

• (2) 15/16” wrenches or adjustable wrench
  

1. Place machine in operating position with power supply connected.
2. This sensor must be set in proper position and at the proper sensitivity for accurate operation.
3. To adjust the physical position of the sensor, verify that the sensor extends 1-3/8" (35mm) beyond shield at its base and adjust if necessary using the 15/16" wrenches or adjustable wrenches.
4. To adjust the sensitivity of the sensor, use a small screwdriver supplied in spare parts kit, to increase (clockwise) or decrease (counterclockwise) the sensitivity adjustment (yellow slotted dial). The factory-set position is with the slotted dial at approximately 3 o’clock.
5. While the machine is on the approach, the LED on the sensor should be Off. Rotate the sensitivity adjustment clockwise so the LED turns On and then counterclockwise so it is Off. Place finger underneath sensor and the LED should turn On and then Off once the finger is removed. If the light stays on, then adjust sensitivity down (counterclockwise).
6. Run the lane machine to verify proper sensitivity adjustment, if it returns too early then increase the sensitivity.
7. Verify that the end-of-lane sensor does not contact the lane when the front lane-to-lane castors drop into the gutter at the foul line.

Adjusting the 3^rd generation End of Lane Sensor

This style End of Lane Sensor has an adjustable sensitivity control that has been preset to the position shown below by Brunswick. The range of this adjustment screw is 270 degrees (135 degrees to either side of the position shown).

Do not force this screw more than 1/3 turn past the position shown.

Sensitivity Control Operational Indicator (Yellow) Power Indicator (Green)

This sensitivity control should result in a steady signal (shown by the yellow operational indicator light) while the red end of the sensor is within 4-6” of the lane or approach surface. This yellow operational indicator light should turn off, indicating that the sensor has gone past the pin deck end of the lane, if the lane surface is greater than 6” from the red end of the sensor.

Note: The mounting nut will cover the sensitivity control when the sensor is properly mounted on the front of the lane machine. Also, make sure to re-use the black O-rings from the original sensor while installing the new sensor.

Check of GUI Settings, Run Time Log and Observing Travel in Pin Deck (no meter or opening of enclosure).

• STEP 1: When encountering any Envoy Travel Speed or Stalling issues, first determine the selected Travel Speed in the Pattern Design Parameters screen of the GUI. Record the selected speed below:   GUI Software version: ___

Quick Clean ______ ?                (62 – 72 second Run Time Range, Target 67 seconds)

Heavy Clean ______ ?               (70 – 80 second Run Time Range, Target 74 seconds for v3.04 GUI software)

Max Clean ______ ?                  (78 – 88 second Run Time Range, Target 82 seconds for v3.04 GUI software)

• STEP 2: Review the Run Time Log to see if the Actual Run Times are in the proper time ranges selected above. It is best to record the data for lane #5, lane #15 and the last lane in the space below:

Lane #5 Run Time:  Avg _____ , Hi _____ , Lo _____ , 3^rd _____ , 2^nd _____ , Last _____ seconds

Lane #55 Run Time:  Avg _____ , Hi _____ , Lo _____ , 3^rd _____ , 2^nd _____ , Last _____ seconds

Last Lane Run Time:  Avg _____ , Hi _____ , Lo _____ , 3^rd _____ , 2^nd _____ , Last _____ second

• STEP 3: Adjust the Base Voltage for Speed Calculation in the GUI SYSTEM SETTINGS screen. Every 0.5 Volt increase should reduce the Run Time Speed by ~1.5 seconds (unless the Envoy is nearly stalling in the pin deck). Run the Envoy again at least 5 lanes after making this adjustment to see if the run time changed as expected. Always ignore the slower run time of the first lane, unless it stalls in the pin deck.

• STEP 4: Observe the travel of the Envoy as it enters the pin deck. It should gradually slow down ~10 feet before the end of the lane and continue to move smoothly without any hesitation or risk of stalling before it reaches the end of the lane and reverses direction. If the Envoy stalls, note the position of the rear cover in relation to the pin spots (Did the rear cover go past the head pin before stalling? 2” beyond 2-3 spots is normal rear reverse point). Report if any pins are wedged by the side covers in the flat gutters. Does this happen on the same lane? Clean drive wheels with IPA 99 to remove accumulated cleaner or conditioner which would cause slipping.

• STEP 5: Increase the End of Lane speed adjustment in the GUI SYSTEM SETTINGS screen up to the maximum setting of +15. This setting only affects the last 12” of travel at the very end of the pin deck. Don’t be afraid to increase this setting in increments of 5 since the brakes will be applied very aggressively to prevent the machine from coasting past the end of the pin deck with the correct full CCW setting of the KB speed control board DECEL trimpot.

If you have increased the Base Voltage for Speed Calculation near 27 volts in the GUI SYSTEM SETTINGS screen, and the End of Lane speed adjustment is +15 and you are still observing slow, inconsistent travel speed or stalling, then you may need a Voltmeter to continue troubleshooting to determine if the KB speed control Board needs to be adjusted or replaced, if the traction motor is pulling excess current, etc. Inconsistent run times are usually caused by a bad KB speed control board, while rapidly decreasing speeds may be caused by a bad traction motor. 

• STEP 6: Use a voltmeter to check the KB speed control board output to Traction Motor during the Diagnostics Drive Test mode. (See below procedure - “Envoy Traction Motor Voltage Measurement Procedure” showing how to attach the voltmeter and warm up a few lanes)

            Note: This check is just the first indicator that the KB speed control board output is correct. It can easily be run on the approach, but it doesn't assure proper function on the lane where the GUI System Settings,                         squeegee pressure adjustment, and other variables are involved.

< Difficult travel issues require more information from the following steps to resolve >

• STEP 7: Use the following “Adjustment of the FMAX trimpot on the KB speed control board” procedure if diagnostics voltage is significantly less than 14.2V (Remember that the Base Voltage for Speed Calculation and the End of Lane speed adjustment do not affect the KB speed control board output to Traction Motor during the Diagnostic Drive Test mode. The GUI System Settings only affect the KB speed control board output to Traction Motor while running an actual lane.) Skip to step 8 if this voltage is above 14.0V.

• STEP 8: Check Voltage while running a combination Clean & Condition mode on the lane (close covers and tape voltmeter to T-Handle as close to the handle end as possible so you can see the reading while the Envoy is under the pin deck in step 9). Observe the KB speed control board output voltage to Traction Motor while the Envoy is moving at a steady speed on the center 20-40 foot section of the lane. Compare to chart below during Forward Travel (squeegee Down) and Reverse Travel (squeegee Up). Record these voltages and the Run Times for 10 lanes.

• STEP 9: If the Envoy hesitates or stalls in the pin deck, check the KB speed control board output voltage to Traction Motor at the very end of the lane while the Envoy is traveling slowly before it reverses. This voltage should never be less than 5 volt on the pin deck. Be careful to get out of the way when the Envoy returns to the foul line. Trip the Cord Kill Switch or Emergency Stop button if you need to stop the travel of the Envoy.

•  STEP 10: Check the Traction motor current with a Clamp-on Ammeter and compare to the chart above to see if the traction motor may need to be replaced. The covers will need to be left open to view the Ammeter while it is clamped over one of the individual blue or brown wire near the “Drive Motor” connector on the left side of the enclosure. A current reading above 3 Amps during the Diagnostic drive test mode on the approach or above 10 Amps while running a combination Clean & Condition mode on the lane may indicate that the traction motor needs to be replaced.

Envoy Traction Motor Voltage Measurement Procedure

Tools needed:

• Multi-meter that will read DC volt and DC Amperage.
• Small pocket type flat blade screwdriver.
• Sealer or whiteout for sealing the trim pot.
• Phillips screw driver to remove the cover on the electrical enclosure.

Note: Measuring the KB speed control board output voltage to Traction Motor should be made when the Envoy is connected to the AC/DC Power Supply. This will assure a steady 26.5 VDC supply to avoid any variables from a discharged battery. If time doesn't allow for this, the next best option is to run with a fully charged Lithium battery. 

To switch to using the AC/DC Power Supply, first disconnect the AGM or Lithium Battery power cable and power type jumper (#1) from the electrical enclosure (#2). Then locate the AC/DC Power Supply red 24 VDC power cable connector (usually coiled just under the left side of the electrical enclosure). Connect the AC/DC Power Supply cable and AC/DC power type jumper to the electrical enclosure. (See Figure #1)

Figure #1

Then, run 6-8 lanes in a clean and condition mode to warm up the drive motor.

Next, locate the “Drive Motor” connector on the same side (left side looking from handle) of the enclosure as the AC power plug was installed. Leave the drive motor connector plugged into the enclosure. Take your voltmeter leads and put the red lead into the connector wire for the brown wire, and the black lead into the blue wire on the connector like the illustration below (Figure #2). Select on your volt meter “DC Voltage” for this test.

Figure #2 

Using the GUI, navigate to “Maintenance” > “Diagnostics” > “Drive”, then make sure the “Forward” is selected on the right hand button display. Now select and press “Drive” on the left hand button. This should start the drive motor and continue to run at a set medium speed for 20 seconds. The voltmeter should read DC voltage from 14.0 to 14.3 VDC. If it is below 14.0 VDC or you have had to adjust the Base Voltage for Speed Calculation near the maximum 27.0 setting, then the FMAX trimpot of the KB speed control board will need to be adjusted to measure 14.2 to 14.8 VDC while running on the approach in the Diagnostic Drive Test mode (see next process).  

Last Steps: Opening Enclosure to adjust or replace KB board 

Adjustment of the FMAX trimpot on the KB speed control board (inside the Electrical Enclosure)

• Remove the top cover of the electrical enclosure by removing the six screws on the top of the enclosure.  
• Check for any loose terminal connections or discolored wires inside the electrical enclosure.

• Locate the KB speed control board “FMAX” trim pot. This is the first trim pot from the top of the KB speed control board (see Figure #3). While the Envoy is running in the Diagnostic drive test mode, adjust this trim pot to 14.5 VDC to 14.8 VDC. Once this has been obtained, go back to your base speed adjustment and start at the default voltage of 24.0 volts and adjust voltage for speed from there.

Be sure to seal the trim pot with a sealer from an electronics shop or use “White-Out” correction liquid from an office supply store. Otherwise, the adjustment may change from normal everyday transportation.

Figure #3

Again, below are the parameters for each cleaning mode.

   62-72 Seconds Quick Clean

   70-80 Seconds Heavy Clean

   78-88 Seconds Max Clean

Note: Please make sure you run 6 to 8 lanes to warm up the Envoy drive motor and wet the absorbent wiper so that you can get a more accurate time measurement.

• Remove the KB speed control board and replace it with a new 14-100822-800 part that has been pre-set by Electronic Repair if the speed or end of lane performance is still inconsistent.
