Measure the Resistance Between the Common
Connection and the 24V Digital Power Connection
1. Test the resistance as shown below:
2. Look at the value displayed on the multimeter screen and determine if the
resistance is acceptable:
• Pass - The value is initially <500 Ω and then quickly rise to >1000 Ω .
This occurs because the capacitors are charging.
• Fail - The value quickly settles at <5 Ω . This indicates that a short
exists.
See A short exists between the 24V digital power connection and the
common connection or ground (frame). on page 253.
