6.4 Alarm
The RLL400 control-units have a fault contact for feedback. The maximum current for the fault
contact is 0.5 A at 24 V AC/DC.
The fault contact is in operation:
• When the electric motor is thermally stopped
•
When phase failure occurs
•
When the safety switch is operated
• When there is no power supply.
6.5 Safety functions and stop functions
The RLL400 control-unit has the safety functions and stop functions that follow:
1.
Phase detection to protect from a change of phases in the power supply. This makes sure that
the direction-of-rotation of the motor gearbox is correct.
2.
Delay time when the direction-of-rotation is suddenly changed. This prevents that it continues in
the initial direction.
3.
Stops automatically when the safety switch is operated. Manual or automatic control in the
opposite direction-of-rotation stays possible.
4.
Error-message indication with four LEDs on the control board (A2).
5.
Feedback of error messages with a fault contact.
Connect the fault contact to an alarm unit or an alarm input of a
control system.
