4.6. Redundant Speed Signal
If precautions are to be taken with regard to failures of the pulse pick-up, a second pulse
pick-up can be connected to the control unit. In case that an electric generator with
terminal W is available, this signal may be used for emergency operation as well as any
other signal of a tachogenerator.
In case of a failure on puls pick-up 1, the governor automatically switches over to the
redundant speed signal and gives an alarm.
