The reset button is located next to the E-CART display at the right hand side of the E-CART in the electronic compartment. It is accessible from the outside and it lights red in case of a fault condition.

E CART Reset button

The reset button is used to confirm certain statuses or to reset fault conditions by the operator. Resetting a situation and / or a fault message should be done by trained and authorized personnel only because the situation needs to be verified by the operator before the fault gets reset.
The E-CART will start and moves forward after resetting the fault.
To confirm and reset a status where the red light at the reset button stays off, you can simply push the button for 1 sec. to reset...

There are three (3) different colored status lights installed in the front bumper of the E-CART. That makes them visible from a wide range looking at the front of the E-CART. The green, amber and red light can come on or they can blink. All light configurations with their respective meaning are summarized in the table below.

E CART Status light

E CART Status light explanation


Each E-CART has an illuminated display on the right hand side in direction of flow. It is used to communicate general condition and statuses of the E-CART and to call out fault messages.

E CART Display

Once the E-CART gets power it shows numerous screens in the program loading procedure. After that, the E-CART will display its name (number), its set speed and the status it is in.
The following table will call out the different statuses which an E-CART can be in.

E CART Display text

Fault messages will be also shown on the display and the following table calls those faults out and describes the status as well as the recovery procedure.

E CART Display error


Using the E-CARTS in a production environment is uneventful in normal operation. Each CART acts like a pallet on a roller conveyor and behaves as such. The biggest difference is that the E-CART has a controller and you can generate situations which generate faults in the E-CART. Knowing the different fault messages and being able to perform the correct action is mandatory to avert dangerous situations. The following paragraphs go through the potential fault messages and the operator instructions.
 
User interfaces
Each E-CART has a few user interfaces used to communicate to and from the operator. Identifying issues, getting status information and confirming abnormal situations are just a...

Please contact LOGOMAT Customer Service to change the drive wheel assembly if necessary.

Symptom:

The Track Rotate stalles under full load

Root Cause:
The Shuttle is not aligned correctly and it binds
Remedial Action:
Align the Shuttle, so that the carriage moves freely by hand if the motor is disengaged
Root Cause:
Something blocks the movement
Remedial Action:
Check the cable track to work properly and make sure that the Shuttle runs freely without high friction
Root Cause:
Torque setting too low
Remedial Action:
Call LOGOMAT to adjust the torque setting of the motor
Root Cause:
Shot pin doesn’t release
Remedial Action:
Check the program and the function of the shot pin

Symptom:

The Track Shuttle misses...


The switch bracket consists of two switches; one reference travel roller lever switch and one M18 inductive switch for position feasibility. The roller lever switch gets used to reset the motor encoder and the position feasibility gets used to make sure that the shuttle is roughly in the correct area. That double checks the encoder signal before an E-CART gets released.

    E CART Track Shuttle Replacing sensors switches

The shown sensor setup is located on either side of the travel. Intermediate stop locations would have the inductive sensor only.

Make sure that the roller lever switch is not activated when the shuttle is in position. It needs to sense a position behind the actual travel. DO NOT MOVE THAT SWITCH BECAUSE THAT WILL MESS UP THE...



Please contact LOGOMAT Customer Service if the guide rails need to be replaced. The procedure is unlikely but could be required if anything damaged the rail.

The main weight gets distributed by the 2 guide rails and the 4 runner blocks. Those runner blocks have to be greased every six (6) months according to the maintenance schedule. If for any reason a runner block runs hard, lost some balls or got damaged, it should get replaced. There are two fixed and two sliding blocks so that the shuttle doesn’t get stuck if the two rails are not running completely parallel. Both blocks get replaced with the same process and procedure.
  1. Disconnect the power supply and the air supply and prevent it from being switched on by any other person. Make sure that the Shuttle Track is empty and no E-CART is sitting on top of it.
