Epson 214D-1 user manual Counting erratically, Instrument acting erratically

46 Trouble Shooting

Scaling Factor should be set to 1 and the Resolution to whole numbers.

Counting erratically

This can be caused by two factors:

§Setting the input circuit incorrectly

§Lack of shielding on the input wiring

Ensure that the input selection DIP switch is correctly set for the flowmeter attached. Shield the input signal with the shield connected at the batch controller only.

Instrument acting erratically

Erratic operation can be the result of severe electrical interference. Considerable attention has been given to designing the Batch Controller to withstand electrical interference.

However, in extreme cases, loads may be encountered which are exceptionally inductive and may require additional protection. One measure is to use an RC Suppression Network as described in the previous section of this manual.

Another remedy for this problem is to use an isolating relay to switch the load and use the Batcher to drive the isolating relay. The isolating relay should be mounted away from the Batcher and from the signal wiring.

No end of batch, pulse output, or flow alarm

This fault is usually caused by lack of a pull-up resistor or load on the output. The outputs have no internal pull-up resistors and require on an external load.
