Troubleshooting Connections
Basic Unit/Optional Switches Unit
To troubleshoot control loop connections:
1. Connect a DC voltmeter across the input terminals.
For an input current between 4 and 20 mA the voltage varies between 11V
and 9 V respective.
If voltage exceeds 11 V check that polarity is correct.
If the polarity is correct but the voltage is less than 8.05 V, then the current
source voltage is not compliant.
2. Verify that source can supply 20 mA to SVi1000 input. If 20 mA is not attainable,
troubleshoot the source.
