PG DRIVES TECHNOLOGY  I-DRIVE TECHNICAL MANUAL – DIAGNOSTICS 
2.1   Trip Type 1 – Low Battery Voltage 
2.1.1   Low Battery Voltage 
This occurs when the controller detects that the battery voltage has fallen below approximately 13.5V. Check the condition of the 
batteries, connectors and relevant wiring to the i-Drive.  
If the trip is still present after the batteries, connectors and wiring have been checked, the controller may be defective. Refer to 
Section 3. 
2.1.2  Very Low Battery Voltage 
This occurs when the controller detects a sudden drop in battery voltage. Check the condition of the batteries, connectors and 
relevant wiring to the i-Drive.  
If the trip is still present after the batteries, connectors and wiring have been checked, the controller may be defective. Refer to 
Section 3. 
2.2  Trip Type 2 – Motor Open Circuit 
This occurs when the controller detects that the motor has become disconnected at start-up or in standby. Check the motor, 
connectors and relevant wiring to the i-Drive. 
If the trip is still present after the motor, connectors and wiring have been checked, the controller may be defective. Refer to 
Section 3. 
2.3  Trip Type 3 – Motor Wiring Trip 
2.3.1   Motor Shorted To Battery Positive 
This occurs when the controller detects that the motor wiring has been shorted to Battery Positive. Check the motor, connectors 
and relevant wiring to the i-Drive. 
If the trip is still present after the motor, connectors and wiring have been checked, the controller may be defective. Refer to 
Section 3. 
2.3.2  Motor Shorted To Battery Negative 
This occurs when the controller detects that the motor wiring has been shorted to Battery Negative. Check the motor, connectors 
and relevant wiring to the i-Drive. 
If the trip is still present after the motor, connectors and wiring have been checked, the controller may be defective. Refer to 
Section 3. 
2.4   Trip Type 4 – Not Used 
2.5   Trip Type 5 – Not Used 
2.6  Trip Type 6 – Inhibit Active 
2.6.1  Inhibit 1 Active 
This occurs when the controller detects that the Inhibit 1 input is active, Inhibit 1 Speed has been set to ‘0’ and Inhibit 1 Operation 
has been set to ‘Latched’. This input is located on pin 6 of the 14-way Tiller Connector. Check the state of the input, Inhibit 1 
programming, connectors and relevant wiring to the i-Drive. 
If the trip is still present after the state of the input, programming, connectors and wiring have been checked, the controller may 
be defective. Refer to 
Section 3.
