LED
Description
Q1
Switching output indicator Q1
• Orange LED: switching output active
• LED off: switching output inactive
Q2
Switching output/Qa analog output indicator Q2
• LED orange: Switching output active/measurement
value within analog output scaling
• LED off: Switching output inactive/measurement value
outside analog output scaling
Q1 and Q2 in run
mode
•
"Q1" and "Q2" LEDs flash alternately for longer than
10 seconds: fault exists. Check general conditions
such as supply voltage, temperature range,
EMC disturbances, etc.
Q1 and Q2 in teach
mode
•
"Q1" and "Q2" LEDs flash simultaneously: teach is being
performed.
•
"Q1" and "Q2" LEDs flash alternately for 5 seconds:
teach failed.
