Charging the iProbe

The tire probe contains an intelligent charger circuit to help maintain the batteries. Charging of the tire probe is performed using the charger power supply that was delivered with it.

To re-charge the internal batteries of the tire probe:

1. Ensure the Probe is turned OFF.
2. Plug the 12VDC Power Supply (Item 4) into the ‘Charge Port’ (H) on the Probe.
a. The ‘Probe Indicator’ (B) should illuminate FLASHING RED to indicate the Probe is in conditioning charge mode.
b. After 2 to 10 minutes the ‘Probe Indicator’ should change to FLASHING AMBER to indicate it is in fast charge mode.
c. When the ‘Probe Indicator’ (B) goes out the probe is fully charged.

Important Notice:

FULLY CHARGED PROBE:  The charging circuit is ‘Intelligent’, so if the Probe's indicator LED does not illuminate when it is first plugged in, the battery is fully charged.

FULLY DRAINED PROBE: If the Probe’s battery has been allowed to go totally flat for an extended period of time this can cause the battery to reject the charge and terminate early. In this situation when the charging stops place the probe straight back on charge again. Keep putting the probe on charge repeatedly until it has had a total of 4 hours charge time. The battery should recover after 2-3 charge / discharge cycles.

Troubleshooting

If the ‘Probe Indicator’ remains in conditioning charge mode (FLASHING RED) for longer than 20 minutes this could mean the following:

  • The environmental conditions are not correct. (I.e. too cold or too hot)
  • The intelligent charger circuit has got out of sequence.
  • There is a fault with the probe or battery.

If this occurs first try unplugging the probe’s charge cable from the charge port on the Probe, waiting for 20 seconds and plugging back in again. If this has no effect try charging in a more acceptable environment.
