TrCM | Trailer Control Module
The Trailer Control Module is a trailer brake valve with an emergency brake device, combined with a double push-pull valve (shunt- and parking valve) as well as a pressure protection valve. The shunt valve allows the cancellation of the „emergency braking“ function by pushing the black knob (with the supply line disconnected). Actuation of the parking brake valve by pulling/pushing the red knob applies or releases the spring braking system.
IMPORTANT! The parking brake system must always be manually activated before uncoupling (pull the red button).
The pressure protection valve, integrated with backflow prevention, ensures the priority compressed air supply to the braking system and prevents any adverse initial pressure influence between the braking system and auxiliary equipment (e.g., air suspension). The provisions of 71/320/EEC and ECE RB/09 and § 41 StVZO are fulfilled, see TÜV Report No. KO250.3E on the documentation page.
