Coding of components
All components have been provided with number codes.
Structure of the code
First digit
Where one connection performs several functions, additional 1st digits will be allocated. These are separated by a hyphen.
Often used:
1energy supply (pressure)
2energy discharge (outgoing command)
3bleeding
4control connection (incoming command)
Little used:
0 suction connection
5vacant
6vacant
7anti-freeze connection
8lubricating oil connection
9coolant connection
Second digit
If there are several connections with the same function, a 2nd digit will be added immediately after the 1st one.
Application example: empty/load relay valve
Meaning:
1air compressor energy supply
2energy discharge (command) to the next component
41control connection (incoming)
42second control connection (incoming)

The bearing pattern of the brake lining can be improved by grinding down the brake lining to a diameter which is max. 1 mm smaller than the drum diameter.
The space between brake shoe and lining must not be more than 0.1 mm.

Brake drum General
A brake drum may be used until the inside diameter has reached the maximum permissible value, as specified in the table below.
As soon as this diameter is exceeded, the brake drum must be replaced.

This tyre class information is also necessary |

If the tyre size is changed in an EBS 2 system and |

the tyre size of the front and rear axle no longer |

fall in the same tyre class, it is not necessary to |

This overview lists the braking forces graphs |

force graphs can be used to check the braking |

performance of an EBS prime mover. |
