Controller

WARNING The WP2300 must only be operated with the SEM0 traction controller (Part No. 813096- 001).

The use of SEM0 traction controllers with different part numbers can change the characteristics and result in accidents.

When fitting a new SEM0 traction controller with part no. 813096-001 on a WP2300, the controller recognises the truck model and automatically loads the standard parameters for the WP2300 when it is powered up.

If you have changed and stored the standard configu- ration with the programmer, the stored parameters will be loaded the next time the controller is started.

Prepare to remove the traction controller as previously described in the Maintenance section.

Remove the 4 mounting screws and remove the traction controller.

Check the contact pattern left behind by the controller back plate on the heat dissipation sheet. The controller must lie fully flat on the heat dissipation sheet.

If there are large areas with no contact to the controller, replace the heat dissipation sheet to avoid thermal problems.

Clean the contact surface of the traction controller on the truck chassis with a lint-free cloth and use an industry-standard silicon rem- oval agent to remove the residue of the heat conducting paste.

Apply a thin and even layer of Dow Corningâ 340 heat conducting paste, part no. 053051-008 to the floorboard (= contact surface of the traction controller on the truck chassis).

Secure the traction controller again with the 4 screws.

If necessary clean the contact surfaces and refit the power cable (you must follow the instructions in the Maintenance section on the previous page) and refit the connectors for the control lines.

For cold store versions: coat the control line connectors with Dow Corningâ 4 Compound, part no. 053051-006. Paint the controller with an acid- resistant clearseal paint.

Important: After replacing the controller check and adjust the settings. You can adjust the settings to suit the customer’s requirements. Follow the order described as follows.

Brake

Blast off corrosion

check seal for damage

check air gap

The working air gap is measured between the magnetic body and the anchor disk while the brake is applied. It should be set to 0.2 mm. The max. permissible setting is 0.55 mm.

Unscrew the banjo bolts as far as the fixed stop on the friction plate.

Tighten the hex. bolts evenly.

Using a feeler gauge measure the working air gap at several points. It must be uniform throughout.

To increase the air gap slightly unscrew the hex. bolts.

To reduce the air gap slightly screw the banjo bolts into the magnetic body. Then proceed as described above.

When the air gap has been correctly set, torque the hex. bolts to 6 Nm using a torque wrench.
