Wiring the Series 93 The Series 93 wiring is illustrated by model number option.Check the unit sticker on the controller and compare your modelnumber to those shown here and also the model number break-down in the Appendix of this manual. All outputs are referenced to a de-energized state. The final...

Sensor Installation Guidelines We suggest you mount the sensor at a location in your process or system whereit reads an average temperature. Put the sensor as near as possible to the mate-rial or space you want to control. Air flow past this sensor should be moderate.The sensor should be thermally i...
