Installation Guidelines

The TrCM should be attached to the vehicle chassis through
its mounting fl ange, using two or three M 8 (15 Nm) screws
and spacing washers. The maximum tightening torque for the
threaded bushings is 34 Nm. The function plate must be attached
to a visible area near the palm coupling. Ensure that the operating
equipment is easily accessible. Ports that are not needed must
be closed off. When painting, the valve openings must be
protected to prevent paint penetration. Refer to the respective
manufacturer's instructions for the screwed/push-in fi ttings.
Maintenance
Control according to the legal requirements of § 29 StVZO. If
defects are found during vehicle inspections or travel, the valve
must be replaced. In case of soiling or damage, replace the
basket fi lter in connection.
Inspection:
Carry out a sealing and function check as described below.
1. System without pressure
Release valve (black button) must be pushed in (securing the
trailer vehicle previous to this test), parking valve (red button)
automatically pushed out.
2. Initial fi lling
Supply pressure to connection 1. The release valve (black
button) must switch to the operating position (jump out). The
parking valve (red button) remains pushed out.
3. Automatic emergency brake
Lower the pressure at connection 1 to 0 bar. The emergency
brake connection 21 must be automatically activated and the
red button jump out.
4. Pressure limit
Opening and securing pressure (closing pressure) to be
checked with a test gauge at the connections 23, 24 and
25 corresponding trailer manufacturing information. Review
leakage, for example with a leak detection spray.
