The travel command with number 0 deenergizes immediately «K2» and «K3».
If a new travel command is given before the control time has elapsed, the RWF40...
ascertains the direction of rotation requested by the command. If the direction of rotation
does not change, the control time will immediately be replaced by the new value. If
the direction of rotation must be reversed, the controlled output will be dactivated and,
for the next scanning cycle, the appropriate control time is used (time contact interval).
If, simultaneously with the control strategy for the floating output, outputs «K2» and
«K3» (via «RK2» and «RK3») are directly set by the management system, the relay
information from the control strategy and output information «K2» and «K3» have a
logic «OR» connection. «RK2» and «RK3» (opening / closing) must never be energized
simultaneously. In such a case, the response is «K2 = K3 = denergized».
