A. INSTALLATION QUESTIONS

Question: Do I need to connect the PINK and BROWN wires together to lift a forward axle?
Answer: No, the PINK wire will lift the axle the same as the BROWN wire and by using the four-way flasher feature. Connect the forward axle lift solenoid to the PINK wire; connect the rear lift axle solenoid to the BROWN wire.

Question: Should I connect my steer lock to the GREEN wire or to the BLACK wire?
Answer: They are opposite to each other, GREEN is 60 KMPH power ON, BLACK is 60 KMPH power OFF. Please refer to the Reverse-A-Matic(TM) for a complete description.

Question: Can I use an existing ABS block (PN# 200516) to mount my sensor (PN#200512)?
Answer: Yes, if you have an available block, it can be used to hold the Reverse-A-Matic(TM) sensor. The barrel clip (PN#200517) is the same used for the ABS sensors (PN# 200512).

Question: How do I test my Four Way Flasher connections to my RM-60 Module (PN# 200506-60OEM)?
Answer: The Reverse-A-Matic(TM) Diagnostic tool (PN# 200601) has a four-way flasher switch to test the system. A tractor may be used to test the connections.

Question: How do I test the speed lock functions of the RM-60 module (PN# 200506-60OEM)?
Answer: The Reverse-A-Matic(TM) Diagnostic tool (PN# 200601) has high speed sensor simulations to test all functions. A light on the side of the trailer should be connected to the axle functions for road testing a module.

Question: Where should I mount the module?
Answer: The module can be installed anywhere under the trailer within the reach of the sensor. The sensor cable is eight feet long. There is a sensor extension available if you want to move the module to another location. The module is environmentally protected and can be mounted on the frame of the trailer.

Question: Do I need a drop out wiring harness?
Answer: The drop out wiring harness can make installation easier by providing a power and ground connection. It also provides several wiring connections for the module. There are four and seven wire versions available. We highly recommend purchasing the power harness to prevent ineligible warranty claims. Individual male and female moulded bullets are available in all of our colours to make connections easy if you prefer to make your own wiring harness. Refer to the wiring Diagram in our manual.

 

B. OPERATION & SENSOR QUESTIONS

Question: My system is operating backwards?
Answer: The sensor controls this; it should be on the driver's side with the arrow pointing outward from the axle. It should be mounted on a fixed axle.

Question: My Reverse-A-Matic(TM) is not working?
Answer: Check the green LED to see if it has power and refer to the trouble shooting section.

Question: My Reverse-A-Matic(TM) is not working in the shop?
Answer: DO NOT USE A BATTERY CHARGER TO POWER THE MODULE. A battery charger typically delivers unfiltered DC / direct current. A battery must be used; a charger may be connected to a good battery. Use 9 to 16 Volts D.C.

Question: Do I need the Reverse-A-Matic(TM) RM-50 or the RM-60?
Answer:
1. RM-50 (PN#200501-OEM) - The RM50 can be used for three and four axle trailers to meet there SPIF regulations. Two axle trailers can use the backup beeper functions.
2. RM-60 (PN#200506-60OEM) - If you have a five or six axle trailer you need the RM60 to meet all SPIF regulations. The RM60 has many excellent features that can be used on other trailers. The Steer axle lock and the four-way flasher lift are two of them.

Question: How do I lift my axle using my four-way flashers?
Answer: Easy, turn them on for three second, off for three seconds and ON again. It should lift the forward axle if you are traveling under 60 KPH. (35 MPH)

Question: Is there a problem connecting other wiring in to the Reverse-A-Matic(TM) outputs?
Answer: No, the module has normally open relays, other switched inputs should not affect them as long as they are 12 volts and the current is less than 5 amps.

Question: Can I connect a spot light to the Reverse-A-Matic(TM)?
Answer: Yes, if the current is less than 5 amps, the Yellow wire will operate back up lights. An external relay is recommended for high power lights. The module can control the relay to provide more power. Any 12 volt external relay is OK; wheel monitor can supply a sealed unit with bullet connectors.

Question: What are SPIF regulations?
Answer: They are ONTARIO REGULATION 413/05 VEHICLE WEIGHTS AND DIMENSIONS -- FOR SAFE, PRODUCTIVE AND INFRASTRUCTURE-FRIENDLY VEHICLES. Quebec has similar regulations.

Question: Can I use the Reverse-A-Matic(TM) in the U.S.A.?
Answer: It can be used in the United States. Refer to FMCSA part 393 section 207, FMCSA 393.207. for information on suspension regulations. The RM60_D has a Dump valve feature to meet these regulations. Contact Wheel Monitor with more questions.

Question: My Sensor has melted.
Answer: The Reverse-A-Matic(TM) sensor may be damaged if the temperature from an overheated brake exceeds 300*F. Replace the sensor and check all other components on the wheel end.

Question: My ABS light does not work?
Answer: Check to ensure there is not a short circuit on the blue line. Check the connections of the dropout wiring harness if there is one. The Reverse-A-Matic(TM) module has an internal resetting fuse to ensure the module does not affect the blue line power.

Question: I replaced the Module but it still does not work?
Answer: All of our modules are tested before they leave our facility. A problem may exist with the trailer wiring, the ground connection or the sensor. It is likely that the removed module is working properly.

Question: Where do I connect the terminals of the 50 foot four-way flasher cable?
Answer: Connect the 50 foot cable to the left and right turn signals. That is the yellow and green wires on the J560 connector.

D. SIMPLE TROUBLESHOOTING: RM-50/RM-60

We have designed this document to assist with simple trouble shooting! If you are having a problem with a Reverse-A-Matic(TM) system, please check the list below. This process can be made easier by purchasing a Reverse-A-Matic(TM) Diagnostic Tool (PN# 200601) available at Wheel Monitor Inc. and distributors located across Canada.

  1. APPLY +12 volts to the trailer, DO NOT USE A BATTERY CHARGER.
  2. Is the Green LED ON? (This indicates the unit has +12 volts power.)
  3. When the module powers up it will turn ON all of its relays for 1 second and turn them OFF. For safety reasons it will only do this when it is not moving. This will allow you to check the wiring.
  4. THE GREEN LED - The Green LED on the module will help to determine if a problem exists and if it is the following;

    1. The Green LED can help with power input, ground connection, high current conditions, broken sensors and sensor operation.
    2. The Green LED will flash once per second when the trailer is not moving.
    3. The Green LED will be ON solid when the wheel revolves.
    4. The Green LED will flash 3 times per second if it has a problem.

The possible problems are:

I. An output is using too much current.
II. An output is short circuited.
III. The ground connection is bad.
IV. The sensor is broken.

If the Green LED is not ON, then the unit does not have power. Check power and ground connections and voltage.

NOTE: The LED may have been damaged while the unit is still working properly, Please check the relays outputs at power up.
If the LED flashes 3 times per second when the wheel is not moving, then the problem is too much current or and bad ground connection.
A. Check if any of the outputs are shorted. If the module resets within one second, then the current is very high.
B. Check that the unit is grounded to the harness. There can be a voltage difference between grounds on the trailer chassis.

TURN THE WHEEL
Find the wheel with the sensor on it. Jack up the axle.
Turn the wheel by hand.
The green LED will be ON when it reads wheel movement and has no problems.

If you move the wheel and the green LED remains flashing once per second, then it is not reading the ABS tone ring.
A. Check the connection to the sensor, it may have been disconnected.
B. Check the spacing and orientation of the sensor. It should be very close to the tone ring. It should be oriented with the arrow at the back of the sensor pointed outward from the center of the axle. This will require the tires and brake drum to be removed.

If you move the wheel and the LED flashes 3 times per second, it could be too much current draw or a broken sensor.
A. Check the total current, the Reverse-A-Matic(TM) is rated for 5 amps, if it takes several second to reset the module then the current draw is too large. A shorted output should reset the unit when it powers up. A large current may take more than one second to trip the fuse.
B. Check the connection to the sensor.
C. The sensor or sensor wiring may be broken. Replace the sensor and redo the test. This will require the tires and brake drum to be removed. A diagnostic tool (PN#200601) is very helpful here.

Question: My Module does not have an LED?
Answer: Older modules do not have the diagnostic LED light. The start up sequence of turning on the relays for one second will indicate if the unit has power. Disconnect and re-connect the blue wire to check for relays.

1. Check the input voltage on the blue and white wires. It should be 9 to 16 volts.
2. Rotating the wheel in reverse will activate the yellow wire. It is useful it connect a light to this output.
3. The Diagnostic tool will test the module and the sensor of any Reverse-A-Matic(TM) system.
