Fault 07 Motor Over Temperature
InfoCenter Display:
Motor Over Temperature
Fault Description
The motor temperature exceeded the limit.
Circuit Description
Temperature sensors monitor the internal field effect transistors (FETs) and the motor components to protect them from
high-temperature damage. The motor controller reduces the motor current in response to the rising temperature until a zero
condition is reached, which stops the motor.
Conditions for Setting the Fault
The motor load is excessive, causing a high-temperature condition for the motor and/or the motor controller. This could
harm the motor.
Recommended Service Actions
Step 1:
Verify that the fault repeats.
1.
Clear the InfoCenter fault log. Refer to
Clearing the InfoCenter Fault Log (page 19)
.
2.
Disconnect the battery pack for 30 seconds. Refer to
Disconnecting the Battery Pack (page 17)
.
3.
Connect the battery pack. Refer to
Connecting the Battery Pack (page 17)
4.
Start and operate the machine. Refer to the
eFlex Operator’s Manual
.
Pass
The fault did not repeat. Go to
Returning the Equipment to Service (page 19)
and follow the
steps listed.
Note:
If the fault does not repeat, a false detect event may have occurred.
Fail
The fault repeated. Go to step 2.
Step 2:
Check the charge level of the battery.
Check the InfoCenter LCD screen to ensure that the charge level is adequate. If the battery indicator does not show at least 1
full block, connect the battery charger to the battery pack and charge the battery pack to at least 40% capacity.
Step 3:
Check for physical obstructions of the reel and of the traction drum.
WARNING
The reel blades are extremely sharp and can injure you.
When you are removing an obstruction from the reel blades, wear cut-resistant or heavy leather gloves.
Physical obstructions can include twine, rope, wire, debris, a tree branch, etc.
1.
Disconnect the battery pack. Refer to
Disconnecting the Battery Pack (page 17)
.
2.
Remove the obstruction.
3.
Connect the battery pack. Refer to
Connecting the Battery Pack (page 17)
.
4.
Start and operate the machine. Refer to the
eFlex Operator’s Manual
