page 2. Use a multimeter to measure the resistance between the
24V digital power connection and the common connection.
If the value displayed on the multimeter screen is OL, a
short exists between the 24V digital power connection and
the ground (frame). If the value displayed on the
multimeter screen is <1000
Ω , the short exists between the
24V digital power connection and the common connection.
Isolate the short:
1. Disconnect a 24V digital power connection at each end of
the system. This divides the system in half electrically.
2. Use a multimeter to measure the resistance of each half of
the system. The half of the system with a measurement of
<1000
Ω is the half containing the short.
3. Disconnect a 24V digital power connection in the middle of
the isolated half of the system.
4. Repeat step 2.
5. Locate the connection between the 24V digital power
connection and common connection or ground (frame).
A short exists between the
motor power connection
and the 24V digital power
connection. Isolate the short:
1. Disconnect a 24V digital power connection at each end of
the system. This divides the system in half electrically.
2. Use a multimeter to measure the resistance of each half of
the system. The half of the system with a measurement of
<10
Ω is the half containing the short.
3. Disconnect a 24V digital power connection in the middle of
the isolated half of the system.
4. Repeat step 2.
5. Locate the connection between the motor power connection
and the 24V digital power connection.
