PG DRIVES TECHNOLOGY I-DRIVE TECHNICAL MANUAL – OPERATION
• Check the condition of the battery.
• Switch the machine on again and try to drive. If the safety circuits operate again, switch off and do not try to
use the machine.
• Contact your service agent.
8.2 TruCharge Indicator
The way in which the TruCharge Indicator should be read depends on whether the controller is driving, is in Sleep Mode or is in Trip
Mode. Each case is explained below.
8.2.1 TruCharge Indicator Steady
If the TruCharge Indicator shows red, yellow and green, the batteries are charged.
If the TruCharge Indicator shows just red and yellow, then you should charge the batteries as soon as you can.
If the TruCharge Indicator shows just red then you should charge the batteries immediately.
8.2.2 TruCharge Indicator Flashing 1 Bar Slowly And Continuously
The controller is functioning correctly, but the battery voltage has fallen below the level set by either
Battery Lockout Voltage or
Battery Lockout Voltage 2.
Do not operate the machine if the battery is nearly discharged.
8.2.3 TruCharge Indicator Flashes Slowly, Pauses, Then Flashes Slowly Again (even with throttle released)
The controller safety circuits have operated and the controller has been prevented from moving the machine.
This indicates that there is a trip. Please follow this procedure:
• Switch off the machine.
• Make sure that all connectors on the machine are mated securely.
• Check the condition of the battery.
• If the fault persists, count the number of flashes / bars and then try using the self-help guide in
Section 8.3.
• Switch the machine on again and try to drive. If the safety circuits operate again, switch off and do not try to
use the machine.
• Contact your service agent.
When a system trip occurs and the parameter Diagnostic Flash Sequence has been set to ‘PG’, a series of flashes / bars will be
reproduced on the TruCharge Indicator. The number of flashes / bars will mimic the TruCharge Status Indicator Trip Types, e.g.
when the TruCharge Indicator flashes 2 times / bars, pauses, then flashes 2 times / bars again etc., the controller has detected a
bad motor connection. Refer to
Section 8.3 for the full list of trip types.
8.2.4 TruCharge Indicator Blinks On Every 3½ Seconds
The controller has entered Sleep Mode. Recycle the power to reset.
8.2.5 TruCharge Indicator Flashing Rapidly
The controller safety circuits have operated and the controller has been prevented from moving the machine.
This indicates that there is a trip. Please follow this procedure:
• Switch off the machine.
