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 ash 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 ash simultaneously: teach is being
performed.
• "Q1" and "Q2" LEDs ash alternately for 5 seconds:
teach failed.
