3.2 Description
The RLL400 is a control unit to control a Ridder RW motor-gearbox. The
control unit is part of drive units with motor gearboxes type RW45,
RW200, RW240/400/600, RW800, RW1000 /1400, RW1200/1600S or
RW2000S.
The control unit is applicable to:
•
Different supply voltages
•
Different mains frequencies
•
3-phase and 1-phase voltages.
The control unit has a control board with a microprocessor and a semiconductor relay.
The control board has connections for:
• The supply voltage
•
The power supply for the electric motor (EM)
•
An automatic control signal (24 V AC/DC) from an automatic control-system (ACS)
•
A manual control (MC)
•
A fault contact (NC) that can be part of an alarm circuit
•
The PTC thermistor in the electric motor (EM) (if applicable) for thermal protection
•
A digital positioning-meter (RPU).
The limit-switch system is also connected to the control board of the control unit.
The RLL400 control-unit transmits control signals from the automatic control-system (ACS) or
manual control (MC) and monitors if these are processed without malfunctions. The control unit has
rotational-field detection and phase detection of the supply voltage.
The 24 V AC/DC control input is protected from:
•
Control in two directions at the same time
•
Sudden changes of direction.
The control unit has status LEDs to show error messages of the system.
The RLL400 control-unit has plug connectors and terminal strips to connect the cables. To pull the
cables through, out of the housing, the control unit also has cable glands. The protection rating of
the RLL400 housing is IP54.
