Electric Retarder Accessories

KLAM offers a wide range of accessories that guarantee a total compatibility between the electric retarder and the vehicle.

To make a correct installation of the electric retarder in your vehicle, it’s essential to count on the control systems that guarantees the compatibility between both. KLAM designs and manufactures a wide range of electronic devices already programmed depending on the configuration of the vehicle in which they are going to be installed.

Electric retarder control system

Operating with 4 independent high-quality mechanical relays it supplies power in stages to the circuits of the retarder coils. Typically the relays are activated (a) when the driver applies the brake pedal (b) or when the throttle pedal is released or (c) when a manual hand control lever is applies.

5 position lever control (0 plus 4 stages) with this command the driver manually activates the retarder braking power in stages of 25%, 50%, 75% and 100% as needed.

By means of mounting a pressure transducer or (4) independent pressure switches in line with the vehicle air brake line, allows the driver to activate the retarder in 4 stages when applying the brake pedal. The (4) relays will close independently in stages depending on driver brake pedal pressure. Each rely or “STAGE” once closed will result in the retarder to produce 25% of its total output torque, meaning that when all 4 relays are closed 100% output torque is achieved resulting in 85% vehicle braking before the foundation brakes are engaged.

Deactivates the retarder when the vehicle is moving below 2mph or is stopped, thus avoiding unnecessary energy consumption when the retarder does not apply braking. It should be installed whenever the brake pedal control is used and is recommended when installing the manual control only.

Disables the retarder when an ABS event occurs, thus the ABS has full control of the braking on each wheel. When the ABS event is over, the retarder will resume braking one stage at a time.

Electronic retarder control system

New control unit for the electric retarder that supplies voltage to the coil circuits at the same time and proportionally. The braking portion can be activated through a manual switch in the dashboard or a pressure transducer mounted in the air brake line that contains the output air pressure of the vehicle brake pedal. The KLAM control module incorporates features as low-speed retarder cutoff and ABS event retarder cut off, eliminating the need for additional components. As well, it has bi-directional communication via CANBUS SAE J1939, enlarging the electric retarder managing possibilities. It also interacts with the most modern EBS braking systems from manufacturers like WABCO or KNORR-BREMSE. Tailored applications are also possible due to the great versatility of the system.

5 position lever control (0 plus 4 stages) with this command the driver manually activates the electric retarder braking power in stages of 25%, 50%, 75% and 100% as needed.

By means of mounting a pressure transducer in line with the vehicle air brake line, allows the driver to activate the electric retarder when applying the brake pedal. Depending on the drivers brake pedal pressure, the transducer sends a voltage signal to the ECU allowing the electric retarder to produce between 0-100% output torque. The retarder will handle up to 85% of the vehicle braking before the foundation brakes are engaged.

An incorporated function in the KLAM POWER MODULE. Deactivates the electric retarder when the vehicle is running at a very low speed or is stopped, avoiding an unnecessary energy consumption when the retarder is not braking.

An incorporated function in the KLAM POWER MODULE. Deactivates the retarder when an ABS event starts, so this way the ABS has total control of the braking in every wheel.
