LED Signal Description
UL/DIA Green Logic supply U
Red • Valve driver overload, a message for the channels
• Module failure
• System error (see g 14.2 Malfunctions)
• SREG short circuit
Off No logic supply U
2)
UQ1 Green Load supply UQ1 present (UQ1 > threshold)
Red Undervoltage (12 V < UQ1 < threshold)
Off Load supply UQ1 not present (UQ1 < 12 V), e.g. emergency OFF
1)2)
UQ2 Green Load supply UQ2 present (UQ2 > threshold)
Red Undervoltage (12 V < UQ2 < threshold)
Off Load supply UQ2 not present (UQ2 < 12 V), e.g. emergency OFF
BF Red Bus error:
No physical connection
Participant not yet or incorrectly configured
LNK/ACT 1 Yellow Active data exchange with network
Green Connection of the port to the PROFINET IO network active
LNK/ACT 2 Yellow Active data exchange with network
Green Connection of the port to the PROFINET IO network active
1)
The UQ2 LED does not light up at the product variant with 7/8" plug.
2)
The switching point (voltage) for LED UQ1 and UQ2 can be changed.
