How many stages does the Telma transmission retarder operate in at off throttle?

The Telma transmission retarder operates in two stages at off throttle. This system is designed to provide additional braking power to a vehicle, particularly valuable in downhill scenarios or when heavy braking is required.

In the first stage, when the driver takes their foot off the accelerator, the retarder engages and begins to slow down the vehicle using magnetic resistance. This initial stage provides a moderate level of deceleration, helping to enhance vehicle control.

The second stage activates as braking needs become more pronounced. At this point, the retarder increases the magnetic resistance further, allowing for greater deceleration. This dual-stage operation is efficient and maximizes braking performance while minimizing wear on the vehicle's conventional braking system.

Understanding these stages is crucial for operators, as it allows them to effectively manage vehicle speed and enhance safety in various driving conditions.
