• Notes on circuitry and on wiring:
– The lines used for speed sensors are to be shielded. The shield must be connected to the electronics on one side or to the
machine or vehicle ground via a low-resistance connection.
– Cables to the electronics must not be routed close to other power-conducting lines in the machine or vehicle.
– The electronics and the power outputs of a controller must be fed from the same power source.
– The wiring harness should be fixated mechanically in the area in which the controller is installed (spacing < 150mm).
The wiring harness should be fixated such that a phase excitation with the controller occurs
(e.g. at the controller mounting point).
– When wiring the output stages, the maximum cumulative output current for each output stage group should be noted. The
cumulative output current means a permanent, simultaneous actuation of the output stages.
• Notes on proportional solenoids and switching solenoids and other switched inductive consumers:
– The electronics may only be tested with the proportional solenoids connected.
– The proportional solenoids must not be wired with suppression diodes.
– Switching solenoids at the outputs of the controller RC do not need to be connected to suppression diodes.
– Other inductive loads that are in the system but not connected to the controller RC must be connected to
suppression diodes.
Safety features in the RCE
– Faults in the supply voltage are detected by internal monitoring.
– All output signals can be monitored by the microcontroller with the appropriate software.
– For service purposes, the controllers can be operated with all power outputs de-energized.
– The internal watchdog module centrally switches off all proportional and switched outputs in the event of disturbances to the
program execution.
Product-specific notes
– Via the release input, the output stages (proportional and switched outputs) are switched off independent of the CAN bus.
