Bendix antilock systems utilizing the EC-15

™

 electronic

controller assembly provide full vehicle, wheel control braking
for buses, trucks, and truck tractors. By minimizing the
potential of “brake lock-up” on all wheels during aggressive
braking the vehicle retains a high degree of stability and
steerability, and in most cases vehicle stopping distance is
reduced.

In order to provide full vehicle, wheel control braking, the
EC-15

™

 controller assembly is used in combination with the

following components:

- Four, individual wheel speed sensors

- Four, air pressure modulator valves

- Antilock condition lamp (dash mounted)

The EC-15

™

 controller electronics, that regulate the function

of the antilock system, are contained in a die cast aluminum
housing and are environmentally protected. The metal
housing, coupled with the design of the digital electronics,
is intended to provide a high degree of protection from radio
and electromagnetic interference.

A diagnostics display window with 9 light emitting diodes
(LEDs) and a magnetically actuated reset switch is
incorporated in the housing for troubleshooting and
diagnostic purposes.

Two types of electrical connectors are currently used to
connect the EC-15

™

 controller assembly to the antilock

system components; a single, 30 pin, Packard Electric,
150 series “Metri-pack” or a pair of 14 pin, Deutsch, HID 30
series connectors.
