Motor control "round" time logic for Hella

Application:

The Rastlogik Rund 24V control unit is used in decentralized systems. Here, the control units are installed near the motors or, in the case of the control unit
Round 24V control unit is installed behind the switch in a deep switch box. Integrated in boxes, they can be accommodated in suspended ceilings, wiring ducts or on-site recesses
can be accommodated. The control line is looped, i.e. routed from control unit to control unit and connected to it on site.
The control unit is used to control motors with max. 250V~. The control voltage is supplied via an upstream power supply unit.

Function:

Operation is via a control panel and/or switches. The term latching logic stands for a special sequence within the control units for carrying out group and/or individual operation within groups = hierarchical operation
or individual operation within groups = hierarchical structures with latching switches. The latching logic deletes commands that are permanently present via mechanically engaged direction switches
are always deleted when higher-level commands are issued for them, regardless of whether they are in the same or the opposite direction.
This prevents the system from automatically moving in the specified direction again once the higher-level command has been executed
is executed. After the latched position is released, commands issued by these switches are accepted again. via the central or individual switch input
as long as a signal is present, motors can be moved in either direction according to the output voltage. For this purpose, the central input +24VDC is connected to
to the central high/low terminals for the central input and to the high/low switch terminals for the individual switch input. With simultaneous signals from the central control unit and
Switch are present at the same time, the central command has priority over the switch command. Priority is given to the retract command if both direction signals of the central unit or the individual switch are present at the same time
are present at the same time. If operation is carried out via the single switch input and a counter command is issued via the central control unit at the same time,
the relays are switched over with a delay via special electronics to prevent the relays from sticking as with conventional control units
When used as a group control unit, +24V is switched to the terminal, the conductor rail from the control center is connected to the control center input and the group to be switched is connected to the motor output
Group to be switched is connected to the motor output.
