PM3 Troubleshooting

Stuck on Zero

Symptom

The Performance Monitor (PM) comes on and you can navigate the menus, but when you begin rowing or skiing, the monitor numbers stay at zero.

Resolution

  1. Ensure the “tach” (generator) cable is plugged in fully.
  2. Ensure the model type on the monitor matches the indoor rower or SkiErg in use. Check this as follows:
    • On the Main Menu, choose More Options.
    • Choose Utilities.
    • Choose Product ID and look at what appears next to "Model." This should be D or D/E for Model Ds, and D/E for Model Es, Dynamic Indoor Rowers and SkiErgs. If you’ve retrofitted a monitor to an older indoor rower, this should read C, B or A according to the indoor rower you have.
  3. Perform a full monitor reset.
    Warning: Depending on the age of your monitor, resetting the monitor may delete all workout data from the PM Memory; workout data stored on a LogCard will not be deleted. Additionally, following a reset, you may need to re-program your monitor with the correct language, and the current date and time.
    To perform a full monitor reset:
    • Remove both D cell batteries/the battery pack from the monitor.
    • Leave the batteries/the battery pack out of the monitor overnight.
    • Install fresh batteries/reinsert the battery pack.
  4. If the problem persists after resetting the monitor:
    • Unplug the monitor pickup wire and inspect it for frays or breaks. This is the wire that leads from the bottom of the monitor to the flywheel. If frays or breaks exist, the pickup wire will need to be replaced.
    • Inspect the monitor pickup wire port on the bottom of the monitor. If there is a crack in the port, the monitor will need to be replaced.
    • If the wire and port look fine, securely plug the wire back into the monitor.
  5. If the problem persists and you have access to a known working monitor, swap the monitors to determine whether the problem is with the monitor pickup wire or the monitor itself:
    • If the known working monitor stays at zero when you begin your workout, the monitor pickup wire is faulty and must be replaced.
    • If the known working monitor operates normally, the original monitor is faulty.
  6. If you do not have access to a known working monitor, contact Concept2 or your authorized dealer for further assistance. If the monitor is used in a health club or other setting where a user may have sprayed the machine down with a cleaning solution after use, inspect the inside of the monitor and the circuit board for contamination. To inspect the inside of the monitor:
    • Disassemble the monitor.
    • Inspect the circuit board. If contaminants are visible, wipe down the circuit board with a cloth slightly dampened with water.
    • Allow the circuit board to dry and reassemble the PM.

    If the problem persists, or if no contaminants were visible on the circuit board, the PM must be replaced.
