Description
Q1
Q1 switching output indicator
• Orange LED: switching output active
•
LED off: switching output inactive
Q2
Q2 switching output/Qa analog output indicator
• LED orange: Switching output active/measured value
within analog output scaling
•
LED off: Switching output inactive/measured 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.
