System error / warning
Red Off Yellow
• Current not flowing despite ON command
(residual current detected)
• Internal trip
Off Green
(when
switching
element is
ON)
Flashing yellow Group warning due to:
• Thermal motor model overload
1)
• Temperature sensor overload
1)
• Asymmetry detected
1)
• Current limit violation
1)
• Connector monitoring
1)
• Circuit breaker tripped/switched off
1)
• Group warning via input action
• Maintenance timer limit violation
• Invalid parameter value
Off Off Yellow No switching element supply voltage (DC24V S)
1)
Parameterization:
(0): Group fault
(1): Group fault only after ON command
Red Off Flashing yellow No switching element supply voltage (DC24V S)
1)
Parameterization:
(2): Group warning
Off Off Off No electronics supply voltage (DC24V NS)
Red Off Yellow External encoder supply short-circuit
1)
Depends on the parameter assignment
