9 Maintenance

Electronic unit

The electronic unit does not require any maintenance if it
operated in line with intended use under normal operating
conditions.
Note
Manipulation by users shall immediately render the warranty for
the device invalid.

Control actuator

Note
For detailed information on the maintenance of the actuator,
consult the operating instruction of the actuator!
Contrac actuators feature a robust construction. As a result,
they are highly reliable and require minimal maintenance. The
maintenance intervals depend upon the effective load and are
therefore not specified here.
The built-in microprocessor evaluates the actual load factors
(e.g. torques, forces, temperatures, etc.) and derives the
remaining operating time until the next routine maintenance is
required.
Use the configuration program to view this information.
